Making Cement & Concrete Crafts: Mixes & Sealers

Everything you need to know about concrete and cement mixes and sealers for making concrete crafts.

This is the first in a series of concrete crafts posts. This information will provide you with details to help you understand cement crafts mixes and sealers.

After a couple of years of making cement and concrete crafts like planters, and other concrete decorative craft, I wanted to teach myself the nitty-gritty of concrete and cement crafts mixes and sealers.

6 bowls with different mixes for making cement & concrete crafts

The way to learn was to start experimenting. 

What’s a better way to learn about cement and concrete crafts than to conduct experiments?

My goal for this was to usurp as much concrete-making knowledge as possible, so I can make concrete crafts more easily, and better help you. 

I have even more in-depth information on cement/concrete crafts including materials, terminology, safety and clean-up tips, in the post Getting Started: Techniques For Making Cement Crafts.

This post has the 10 best beginner projects for new concrete craftsmakers.

If you are looking for how to know which mix is the right choice for your project, then I recommend you start here first.

However, after reading this, to understand more about the strength and importance of aggregate sizes in concrete mixes, then take a look at The Best Concrete Mix For Your Project.

That will give you more specific information on specifics on why some concrete mixes are stronger for some projects but weaker in others. You’ll learn the best concrete mix for large planters, the best mix for small planters, and what concrete mix to use for stepping stones or pavers.

Cement vs. Concrete For Crafts

First, let’s have a discussion about the terms cement vs concrete for making crafts. Are the terms interchangeable?

Yes and No. In reality, the materials are not 100% of the same ingredients. 

Let me first explain, the “No” (sort of). Most forms of cement are composed of sand and minerals such as clay, limestone, and shale.

Concrete will have these same properties but contains an aggregate such as gravel.

The short answer is- Cement is the main component of concrete, just without the aggregate. 

Now for the “Yes”. When you want to make something like a concrete planter and want to find a tutorial on how to make something, what do you do?

You go into the Google machine and search for ‘DIY concrete planter’.

Google will favor showing you results from websites that use the term concrete more so than show you sites that use the term cement.

This is because, in the U.S., concrete is the term more commonly used. 

But in actuality, do us cement/concrete makers really care if the official tutorial uses cement instead of concrete? Nope.

Why? Because it’s likely the look of a concrete planter that led us to use that term in our search.

You can’t tell just by looking, whether concrete or cement was the material that was used.

By the way, if you’re interested in hypertufa– you can learn more about the mixture recipes and how to make a large hypertufa trough planter here.

You may notice that I sometimes use the term concrete scattered in the introductions of my posts and sometimes even the title. However, I will clearly list the actual material used.

If it was cement, that will be in the materials list and if it was concrete, it will say concrete. I also link to the products you can see which exact type it was.

See my Google quandary? I do this to combat the problem of people not finding my tutorials because of this semi-interchangeable term.

Just rest assured that in my tutorials, the materials list will always use the exact term for the concrete/cement mix I used.

Make sense? 

I have a whole article that goes into more detail on cement vs concrete.

Differences In Concrete and Cement Craft Mixes

comparison of bowls made with 6 different mixes for making cement & concrete crafts

At the bottom of this post, I have given my personal review on the different types of cement and concrete mixes for making crafts.

My review is based on these test results. For a deeper understanding please read through the tests here first.

Pocket Guide to Concrete & Cement Mixes For Crafts
Grab the free pocket guide. It has a handy chart for choosing the right mix for your project.

To gain a better feel for the various mixes, I have tested and compared six different concrete and cement mixes.

I chose these particular mixes because I suspected they were viable for being good contenders for making cement/concrete crafts.

I also made my selections based on availability in my area. 

My tests included making a couple of bowls, small and large for each type of craft mix.

First I’ll give you the official description from the manufacturer, then tell you about my experiences working with these mixes. 

Note: The water ratio mix for concrete of cement for concrete crafts will vary from mix to mix. Climate conditions will also play a factor in the ratio.

Using CTS Rapid Set Cement All For Crafts

the best mix for making cement crafts -Cement All cement mix

Official Description
Cement All® is a high-performance, fast-setting concrete repair material that is durable in wet environments. Apply Cement All from featheredge to 4” thick.

Use for general and structural concrete repair, doweling and anchoring, industrial grouting, formed work, vertical and horizontal trowel applications.

Cement All rapid set. A favorite for making cement crafts

My Tests
Working time is about 10-15 minutes and it can be demolded in an hour. It reaches its final color within a couple of hours after demolding.

The dry mix is a fine cement when water is added, is very smooth and clay-like in texture. The color is more of an off-white to sometimes beige.

The shade of the color can vary slightly from box to box or bag to bag. 

It is easy to work with when making cement & concrete crafts and isn’t finicky in terms of the amount of water needed.

This is in comparison to most of the other types of cement and concrete I have tried here.

Cement Crafts Mix Quikrete Portland Cement -Type I/II

Bag of portland cement for making concrete crafts

Official Description
Complies with current ASTM C150 and Federal Specifications for portland cement.

It can be mixed with aggregate and other ingredients to make concrete mix, mortar mix, and base coat stucco. Available in Type I, Type I/II and Type III.

Dry Portland cement mix. A good option for making concrete and cement crafts

Sand must be added to Portland cement or it will crack (trust me, I did try) ;0}. The Portland mix is a fine cement, but that changes when you add the aggregate.

This Portland mix is the cheapest of the concrete mixes.

Demold time is 24 hours, but it will take another 2 days for the cement to reach its final color. This will dry to a light-medium grey.

The directions call for at least a 3:1 ratio of sand to cement, but this is unnecessary for most cement & concrete crafts.

When I used a 3:1 ratio, I ended up with a great deal of pitting.

I made a bowl using a 1:1 ratio and at that ratio. This was as smooth and moldable as Cement All to work with, and the bowl had the same smooth finish.

I did a whole series of tests on Portland cement and sand ratios where I tested 5 different ratios to see which one was best.

My initial tests show that a 3:1 ratio is durable enough for smaller crafts like small to mid-sized planters, and has the least amount of pinholes.

I found the mix to be as smooth and moldable as Cement All at a 1:1 ratio. The cured bowl came out just as smooth as the Cement-All bowl.

For larger crafts, a 2:1 ratio is what I recommend, which is what I used for the 3D cement tiles in the DIY Cement Tile Planter Box tutorial.

A 2:1 ratio is required for durability beyond that size, but please reference the article I mentioned above for full details on when to change up your ratios.

Using Quikrete Quick Setting As A Cement Crafts Mix 

(Not the same as Quikrete’s Fast Setting Concrete)

Quick setting cement mix to use for concrete crafts

Official Description
Specially formulated to set in approximately 10–15 minutes. This can be molded or sculpted into place.

  • Making concrete repairs where rapid setting is required
  • Ideal for repairing broken edges of concrete steps and curbs
Dry quick setting cement

My Tests
This sets about as fast as the Rapid Set Cement All and is similar in texture, in that it is very smooth and clay-like.

It can be demolded after 16-24 hours.

The final color will be medium grey with just the slightest hint of brown, and will take about 2 days to reach that color.

And like the official description claims, it is quite moldable. 

Using Sakrete Top n’ Bond Concrete Patcher 

Top n' Bond mix to use for diy concrete projects

Official Description
Sakrete Top ‘n Bond Concrete Patcher is a polymer modified sand cement repair mortar requiring only the addition of clean potable water.

For applications from 1/2” (13 mm) to feather edge. For refinishing, patching and general repairs to concrete/masonry.

Dry Top n' Bond cement

My Tests
The Top n’ Bond demolds in 24 hours, and takes 2 days after demolding to fully cure and reach its true color of light grey.

It’s a little easier to form into shape than many of the others tried here. It is supposed to be suitable for making cement & concrete crafts requiring layering.

Using Quikrete High Strength Concrete Mix For Crafts

High strength concrete mix

Official Description
This is the original 4000 psi average compressive strength blend of portland cement, sand, and gravel or stone.

Just add water. Use for any general concrete work.

Dry High strength concrete mix

My Tests
This concrete will require sifting out some of the aggregates to be used for crafts. The gravel is quite large and there’s a lot of it.

For this test, I only sifted out the larger rocks, and the concrete bowl still resulted in a fair amount of pitting.

I believe with more sifting, you could reduce most of the pitting. 

The color is a light to medium grey but does have a bit of brown in it. It almost looked as though it contained some dirty sand.

The high strength mix demolds in 24 hours and takes 2 days after demolding to fully cure and reach its true color.

This is not the best mix for casting concrete if your mold has narrow cavities.

Using Quikrete Sand Topping Mix

Sand topping mix

Official Description
Consists of a uniformly blended mixture of portland cement, commercial grade sands and other approved ingredients.

sand topping dry mix cement texture for making cement and concrete crafts

My Tests
This sand and cement mix has a very sandy texture when working with it.

Demolding time for Sand Topping Mix is 24 hours. It takes 2-3 days after demolding to reach its final color which is a light grey.

The demolded bowl looks similar to the Quikrete High Strength mix, but it doesn’t contain stone aggregate.

I repeated this test twice and both times the cement bowls came out with large pinholes.

When using this mix for a thicker project, pitting hasn’t been a concern.

With the concrete coasters test, I needed to add a lot of water to the mix to get it thin enough that I would be able to vibrate out the air bubbles.

The mix doesn’t do well with too much water and weakens the cured piece. 

I had no problems with pitting in these two projects, which were both 2 inches or thicker, or slightly more.

This concrete mix is best for making stepping stones. It’s what I used for the DIY Natural Looking Stepping Stones and Concrete Side Table With Flowers.

Demold and Cure Time Effect On Cement Crafts Sheen

I performed the same test on both a matte cement piece and a shiny cement piece for most of these.

I believed this was important to do since sheen has a big effect on things such as water evaporation, color, and texture.

To get a matte texture, I needed to demold the Cement All early.

By waiting another 1-2 hours past demolding time, I was able to ensure that cement piece would be shiny.

I made sure to test both sheens of cement where I thought it could come in to play.

The cement demold times in the tests are based on a temperature of about 68-73 degrees.

In colder temperatures, the demold time will be extended and warmer temperatures, demold may be shorter. 

Another large factor in the demold and cure time is going to be the thickness of the cement craft.

Something with a ¼” thickness can often be demolded in under an hour.

Whereas when something is ½” or 1” thick, you may want to wait several hours.

These cure times and sheen tests are based on crafts that are closer to ¼” thick.

matte and shiny cement planters

Cement All has the most pronounced effect on sheen, which comes from the duration of cure time before demolding.

In the photo, I’m showing two examples of cement planters.

I made these in a tutorial and put magnets in them so they can hang on your refrigerator.

Here’s the DIY Cement Magnetic Planters post if you haven’t seen it.

The 1st cement planter ball (on the left) was demolded in less than 45 minutes. You can see that it is nearly completely matte.

Cement ball #2, on the right, was demolded after a couple of hours and is glossy.

a matte and shiny sheen left on cement bowls, difference to know for making concrete and cement crafts.

Here’s an example of sheen differences using the Top n’ Bond Concrete Patcher.

I made these concrete bowls twice using this mix. The first concrete bowl, I demolded after 24 hours and the surface was matte.

I demolded the second bowl after two days and the surface was shiny. Even though it did lose some sheen over time, it has settled in with a satin finish.  

When I tested a few of the non-Cement All products, the results showed somewhat of an effect with sheen. These effects were not nearly as pronounced as the Cement All.

Aside from the Cement All pieces, the sheen on the concrete became muted as the days and weeks went by.

The pieces that were demolded later, did retain some sheen, but were closer to a satin appearance.

The lesson here is, demold early (though not too early) for a matte appearance.

Demold late for a shiny appearance. The longer you wait, the more sheen you will have. 

For more information, here is an article on four ways to make concrete shiny.

Effects Of Using Lubricant On Cement Crafts Molds

For this cement crafts test, I wanted to prove what I had noticed on the few occasions when using a lubricant to help in the demolding process.

The first part of this experiment was to determine if discoloration was caused by lubricants, and if so, to what extent?

3 cement spheres tested with lubricants for demolding and how they would look on concrete crafts

Effect Of Concrete/Cement Crafts Lubricant On Color

There were two types of lubricants that I used on the molds of these cement spheres.

I made one sphere without using any lubricant so we’d have a good comparison. 

The sphere on the left is the subject without lubricant.

The middle cement sphere has baby oil applied to the mold. And the third lubricant has vegetable oil sprayed inside.

To start with, the baby oil is clear in color and the vegetable oil, of course, has a yellow tint.

Did this color difference transfer to the cement?


You can see in the photo, the non-lubricated sphere has no discoloration.

The middle sphere does have a slight yellow tint and the cement sphere to the right has a pretty distinguishable yellow tint.  

Effect Of Concrete Crafts Lubricant On Texture

Now, the second part of the cement lubricant test was to check to see what the lubricant did to the texture of the cement.  

Referencing the same photo above, again, the sphere on the left didn’t have any lubricant in the mold.

I applied baby oil, using a cotton ball, to the middle sphere. This gave me something to compare to the bubbles that are created by a vegetable oil spray. 

The results were that the non-lubricated cement crafts piece is the smoothest and has the least amount of pinholes.

You’ll see a moderate amount of pinholes on the sphere with the rubbed-on baby oil.

And the vegetable oil sprayed sphere has the most amount of pinholes and even has some pitting. 

Vibration Effect on Concrete and Cement Crafts

3 cement pieces with pinholes and pitting

This one should be pretty obvious on how it turns out.

However, I wanted to compare just how different the effect would be, based on the level of vibration and how much is really necessary when making cement & concrete crafts. 

These cement pieces were cast inside a plastic cup.

Other than a couple of quick taps on the work surface, which allowed a bit of cement to settle, the piece on the left was left alone.

For the middle piece, I tapped on the work surface and tapped and shook the sides for about 30 seconds.

The third piece, to the right, was tapped a few times and then I used a power sander (without the sanding pad) and vibrated it against the cup for about 20 seconds. 

As we all probably expected, the piece on the left that was basically left alone has lots of pitting and pinholes.

The piece in the middle that was manually vibrated and tapped, has a few pinholes and just a little bit of pitting.

And finally, the right-side piece with the power vibration, shows the smoothest texture, no pitting and has only a few pinholes. 

Concrete Crafts Sealant Effect

The Effect Sealant Has On Cement Sheen

** Updated 3/6/20– see the colored planters below*
The concrete sealant I used is a matte sealer, which is what I had on hand, and at some point in the future, I will perform these tests with a high gloss sealer.

I applied a matte sealer to three different cement planter balls, but to only one side of each cement planter ball.

I chose three planters that had different sheens before the cement sealer application.

Being a matte sealer, instead of shiny, there isn’t a strong visual difference, but the results were still interesting. 

In real life, I can actually see the sealer on each of these.

Unfortunately, no matter what I did with the contrast and lighting, I couldn’t get the camera to pick up what I could see with my naked eye, so bear with me.

I have the arrows pointing toward the side where the sealer was applied.

3 cement planters with sealer on them

Here’s what I did to test the effect of a concrete/cement sealer on cement.

To get three different sheens as starting points, each of these cement planters was demolded at different times during the curing process.

The cement ball on the left started out matte and has a rougher appearance. If you look at the photo, you can see the sealer on the left half of the ball.

On this matte planter, there is a visible sheen from the unsealed half. You may also notice, the sealed side is a bit darker.

The middle ball started out with a natural satin sheen. Again, the sealer was applied to the left side.

On this satin cement planter, the sealer is barely visible and doesn’t add any shininess, but is slightly darker.

The ball on the far right shows the sealer applied on the right side.

The results were nearly the same as with the satin sheened cement ball.

It also has a slightly darker look where the sealer was applied, but it is also very difficult to discern any difference in shininess.

3 cement crafts comparisons with sealant

Now, when I tested these sealers with matte cement planters that I colored after curing, using alcohol ink- look what happened.

The one I sealed (on the left) does have a very noticeable sheen despite the sealer being “matte” according to the manufacturer.

This sealer was the Easy Seal.

The cement planter in the middle had the Stone Care spray sealer and it is truly matte.

The one on the right doesn’t have any sealer and is equally as matte as the planter in the middle.

To learn about how I tested various ways to color concrete crafts, check out the Concrete Crafts Pigment Tests- How To Color Concrete And Cement.

The Effect Concrete Sealant Has On Discoloration From Soil

This was probably the test that I most looked forward to as I was especially curious about this.

I had noticed with my own cement planters that some of them become discolored after being planted.

I assumed this was due to the soil mixing with water and then coming through the pores of the cement. 

This discoloring effect doesn’t happen with every cement planter I make, so I decided to test the effect of whether a sealer would avoid or at least reduce the amount of discoloration.

The other question was whether or not the shinier cement planters were naturally protecting the cement from discoloration. 

Each planter had its drainage hole plugged (for quicker results) and was filled with soil and water.

The first 2 test planters were unsealed. For the unsealed, I had one that was matte in sheen and one that was shiny.

The planter that I sealed, was very matte to start with and I applied sealer on the inside and out with one coat. 

3 different cement planters sealed and unsealed and discoloring effects

In order from left to right in the photo, these were the results.

Cement Planter Ball 1 (Left)
Sealed: No
Sheen: Smooth, shiny
Result: No discoloration

Cement Planter Ball 2 (Middle)
Sealed: No
Sheen: Matte
Result: Dark discoloration due to salts in the soil

Cement Planter Ball 3 (Right)
Sealed: Yes
Sheen: Matte
Result: No discoloration on one side, but the backside has a grey color- wet appearance
-I suspect the sealer wasn’t evenly applied on the backside, but without sealer, it would have looked like the planter in the middle.

The Effect Concrete Sealant Has On Water Evaporation In Planters 

These next two tests will show us how much water is absorbed in a cement planter.

We all care about plants and want to care for our plants properly.

I wanted to know if by sealing a cement planter, would the planter retain more water?

Surely a plant in a plastic pot will need less watering than a cement pot.

But how much of a difference in evaporation between a sealed cement pot and unsealed? 

If you are wondering about whether Concrete Pots Are Safe For Plants, then check out this article about plant health and concrete.

And here’s a tutorial on how to seal a concrete planter.


To get a good comparison, I started the test by comparing water evaporation in a plastic container, vs an unsealed cement pot.

bowl showing water absorption with plastic cup

I added 4oz of water to a plastic cup and 4oz to a cement planter.

It took a little more than a week for the water to disappear and of course, it was from the cement planter.

The plastic cup still contained 3 of the 4 ounces of water. Quite a difference.

How Much Water Evaporation Is There in Sealed Cement vs Not Sealed?
2 cement vessels one empty, one with water

The second stage of this test was to compare the absorption of water in an unsealed planter versus a sealed cement planter. 

I made two cement vessels (no drainage holes) and I sealed one, both inside and out. The other remained unsealed. 

I added 2 oz of water to each cement vessel.

In less than a week, the water had completely evaporated from the unsealed vessel.

In the sealed vessel, a little more than a tablespoon of water remained in the sealed container.

There you have it. Something to consider when making your planters.

Depending on the type of plant, is it more helpful to seal it, or leave it unsealed?

Sanding Options for concrete & cement

one cement planter sanded, one not sanded. Sanded is yellow.

And for the final test, sanding effects on cement crafts.

For those of you who have followed some of my tutorials, you probably notice that, with few exceptions, I don’t sand my cement crafts.

I usually only do this when there are sharp edges or a rough, top edge of something like a planter, bowl or vessel.

Here’s why, with most of the crafts I make, I usually choose a smooth cement-like Cement All.

There are other concrete and cement mixes here that also are very smooth and I wouldn’t sand those either.

In this test, I demolded the planters early to achieve a matte sheen when cured.

I used a 220 grit sanding sponge for the one on the right and did not sand the planter on the left.

Do you see the yellow tinge? 

I don’t know what causes this effect, but sanding creates an unwanted effect on the cement’s sheen and color.

I have tried all levels of sand-paper grits, as well as various diamond grit sanding sponges and they all create the same effect.

Other than the very uneven rough spots, I do not typically sand the majority of my pieces.

My Personal Review Of The Six Different Types Of Concrete And Cement Crafts Mixes

This review is based on what I’ve learned so far about the six different types of cement and concrete mixes specifically for making crafts, through these tests. 

I had high hopes for the Quick Setting Cement.

Though this can be demolded in a couple of hours, it still takes a day or so to reach its final color and be cured enough to use.

It’s more practical for me to just use Cement All and add a little black to it if I’m going for a grey color.

I don’t have much experience with this product outside of the tests, but I have a whole bucket-full of it so I will continue playing.

There are two mixes for cement crafts that piqued my interest the most.

One is the Portland Cement because it’s moldable, very smooth and can have a sheen. It’s very much like the Cement All, but has a longer working time.

This can be incredibly helpful at times. It takes a day before you can demold and two days more to be fully cured.

If I need a long working time, this could be a good choice. I do like the control of how much sand to add.

The negative to this Portland Cement is that in my area, it’s only available in a 90lb bag. Okay, really? 90lbs is pretty impractical. 

The Sand Topping Mix is just over-the-top sandy, and very rustic.

If you prefer a really rustic look, the Topping Mix may be a good option as the sand is already added, so it’s one step (unlike Portland Cement)

The other product with high potential is the Top n’ Bond.

It’s not too sandy and therefore I find it easy to work with and also easier than the others (for me) to determine how much water it needs.

I like the grey color it has, and I find the frosted/satin finish interesting. The bonus is that it is available in 40lb bags in my area, so is easy to handle.

The High Strength Concrete mix is the least expensive mix out of the six concrete types listed here.

However, if you are making smaller crafts, by the time you sift out all the aggregate you may not be left with a whole lot of workable concrete. 

What’s the best concrete mix for crafts?

There’s no perfect concrete or cement, the best mix is what works best for you, your project and what’s available in your location. What’s my favorite? 

Well, concrete and cement have about a 6 month shelf-life, after being opened.

As a concrete craftsperson, I have to be practical and it is easier to stick to one type of cement or concrete, even though sometimes there may be a slightly better choice.

Cement All is still my favorite for crafts for its quick setting workability and cure time. I love its moldability, and extremely shiny and smooth final texture.

Additionally, Cement All is the smoothest mix for making cement crafts, and the hardest after it cures.

I’m impatient and it’s helpful to know in a few hours if my cement projects have failed.

If I need a cement that has a longer working time, at the time of writing, Top n’ Bond will be my cement mix of choice.

Please keep safety in mind when working with concrete and cement mixes. To read more about this, take a look at Safety Concerns With Concrete For Crafts.
