Easy DIY Concrete Coasters With Leaves

These handmade concrete coasters are the perfect way to accent your home decor for fall.

I never seem to have much fall decor, so I’m changing that this year by making my own concrete coasters with fall leaves.

The Easiest Way To Make Concrete Coasters

Last year I made homemade concrete coasters using a cardboard mailing tube, which was a great use as a concrete beverage coaster mold.

But using pre-made silicone molds is the easy way to make DIY coasters, and so this time, it’s the route I decided to take.

At first, I thought I would make square ones because I already had a square concrete coaster mold.

But I had forgotten how rounded the corners were, which made them less modern, so I opted for these round ones.

How To Make DIY Concrete Coasters With Fall Leaves Materials List

*Materials Note UPDATE: When I originally made these I used Cement All and not Sand Topping Mix. I have since had trouble with water mark rings caused by from sweating from glasses.

This is likely from sanding the top to remove the scratches. I have not had any staining with my heavily used flower coasters, in which I used Sand Topping Mix.

Because of this, I have re-written the tutorial using Sand Topping Mix instead. It actually saves you a step, but you do need to wait 24 hours before you demold this mix, instead of the 1 hour with Cement All.

How To Make Concrete Coasters With Leaves Tutorial Steps

Concrete Coasters-materials for making concrete coasters that have fall leaves imprinted in them and painted fall colors

Before starting the tutorial, it may be helpful to read my article comparing the different concrete mixes and sealers– Cement & Concrete Crafts Tests!

Another important article is Making Cement Crafts Techniques & Tips with info on cement materials, mixture consistencies, demolding, safety and clean up!

Step 1. Find Leaves For Making The Concrete Imprint

Concrete Coasters- shiny young leaves from sapling in ground.

Take a walk around your yard or neighborhood park and look for the smallest leaves you can find. Sometimes these will be stems growing from the grown that were seedlings. 

The fresher, the better. If the leaves are a little old or dry, they’ll be tougher to remove from the cured concrete. 

The leaves should be no bigger than 3” long because the silicone mold is 4”. But if you are placing the leaf diagonally, you’ll have a little more room.

I like to leave a fair amount of empty space around the leaf so that it doesn’t overtake the whole coaster.

Step 2. Adhere The Leaves to The Concrete Mold

Concrete Coasters- spray adhesive and two leaves, face up on cardboard- with adhesive sprayed on top of them.

You will want the leaves face down when inside the mold so that the backside is facing you because the veins are stronger and it will leave a finer imprint.

You will use spray adhesive to glue each leaf to the bottom of the silicone mold.

Start by placing the face (smooth side) of the leaves facing up on cardboard on either newspaper or old cardboard.

Follow the instructions on the spray adhesive and then spray the entire surface of the front of the leaf.

And since spray adhesive works very quickly, I recommend only spraying the leaves two at a time to give you enough time to position them. 

Concrete Coasters- silicone mold with a leaf inside of each cavity, smooth against bottom.

Carefully lift the leaves and place them diagonally into the concrete silicone mold cavities.

Position them first before pressing, then press firmly and be sure you have them fully flat against the mold.

If any part of the leaf is raised from the mold, the concrete will get underneath, which will make it difficult to remove.

Step 3. Prepare The Concrete Mold For Casting

First, place your mold onto a flat surface that you can transport, like a rigid board. This will help you vibrate it after casting because the mold has soft sides.

The rigidity of the board allows you to vibrate it without deforming the soft sides of the mold while doing so.

Concrete Coasters- close up of leaf inside mold cavity and craft stick showing marks of 1/4" from bottom.

Now if you want thinner coasters like mine then make the thickness of the coasters about ¼”.

So place a ruler inside and measure up ¼” from the bottom and mark this with a permanent marker on the side of the mold.

This will be the stopping point for the cement.

Now if you prefer chunky-style coasters, then you can pour the concrete closer to the top of the mold.

You’ll see in the photo, I couldn’t find my ruler, but I had another coaster I could use as a guide.

So I just marked a craft stick at the height of the coaster and then used that to make my marks inside the cavities. 

Step 4. Mix And Cast The Cement Mixture

Concrete Coasters- wet concrete mix with black powdered pigment sprinkled on top.

Add the dry concrete mix to the bowl and then add some black powdered pigment. You can see how much I added here.

It can be difficult to tell how much you need and is a little easier when it’s wet, so mix the black in with the dry first and then add water.

Concrete Coasters-hand over cement mixture, holding cement that has slow drip back into bowl.

Don’t forget to wear gloves when you mix concrete. You will need to mix this to the right consistency, which is like brownie batter.

Once this is mixed well, check to see if you think you want to add more color.

You can see from my wet mix, what the color was–compared to the color they cured to. The dry piece will always be quite a bit lighter.

Concrete Coasters-concrete mix in silicone cavities, lumped up inside.

Double check that there aren’t any lumps and then scoop some mix into each mold cavity. 

Give the mold a few shakes to settle the concrete and check to see if you need to add more, or remove some to meet your marked stopping points.

Concrete Coasters-silicone mold with 6 round cavinbities, filled with vibrated cement.

Once each cavity is filled to the line, use the board the mold is on and shake and tap it onto the table to get the mold vibrated. 

You should see air bubbles rising to the surface of the coasters and once they slow down or stop, you can let this sit to cure. I vibrated mine for about a minute and a half.

After vibrating, let these cure for at least 24 hours, depending on room temperature/climate conditions.

Step 5. Demold And Sand The DIY Concrete Coasters

Concrete Coasters-coasters on table with silicone mold. Mold is upside down and peeled back with some coaster out and others coming out.

Turn the mold upside down and then press each concrete coaster out of its cavity and then remove the leaves from inside the concrete.

Be sure to wash the silicone mold with warm soapy water when you’re done, especially because there will be some adhesive residue stuck to it.

Some of these leaves you may be able to lift with your finger to peel them out. For others, you may need to get an edge started by using the backside of the X-acto knife blade to lift up a corner.

Take care not to scratch the coaster while doing so. You may have a little debris leftover from the leaves.

Now sand the sharp edges on the bottom and make sure they are sanded well enough that they are flat and don’t wobble.

Step 6. Paint The Fall Leaves With The Acrylic Paints

To paint the concrete coasters, first place a little dab of gold paint into the paint tray, then paint the leaf with a dry brush–don’t dip the brush into water.

 Just tap and dab it on the leaf, taking care to get the gold into all the veins.

Now take a soft cloth and dip it into some water. You only want the rag to be damp. The paint has probably mostly dried already, so take the cloth and rub it over the painted concrete.

The harder you rub, the more paint you’ll remove so how much you rub will depend on how dark you want the gold paint. 

The good news is that this is something you can play with. If you don’t like the way it is turning out, you can rub it all off.

I recommend letting it fully dry first though before deciding because when you first do this, the wet areas of the concrete will be dark, which will look different when it dries.

If you want to add orange, then after the concrete from the gold has partially dried, dab a little bit of orange on a dry brush.

I placed my orange through the center of the leaf and its lobes (the pointy parts).

Now use the damp cloth to first blend the orange in and then you can rub it off.

If you got paint on the non-leaf area of the coaster, you can sand it off with the wet sandpaper.

But you need to wait until the paint is dry, because you’ll need to rinse off the coaster after and you don’t want to rinse off the paint inside the leaf.

Step 7. Seal The Coasters To Protect The Finished Product

Once the paint on the concrete coasters is completely dry, and the concrete itself has been demolded for at least 6 hours, you can seal them with the acrylic concrete sealer. 

It’s especially important the paint is dry as you don’t want to accidentally rub any off as you are applying sealer, so it’s best to wait until the next day to be safe.

Concrete Coasters-finger with cloth wrapped around it, rubbing concrete sealer into it.

Pour some of the sealer into a small bowl or a cup and use the foam brush to apply the sealer to the coaster. 

Sometimes the brush marks will show when using a foam brush or any brush, so instead of using that to brush the sealer on, I recommend using a soft cloth.

Take the cloth and dip it lightly into the sealer and then rub the sealer in.

This dries fairly quickly, so I first sealed the back side of each coaster. Then after about 5 minutes, I was able to seal the top and sides of each.

To give the coasters extra protection from stains, I like to apply a second coat. If you use my sealer, then you should wait a minimum of six hours before recoating. 

I have the flower concrete coasters I made a year ago and this is how I sealed them, using the same sealer and none of them have any staining. 

However, they have not been tested with red wine, as I am a white wine drinker. :0)

The sealer should be fully absorbed and completely dry before moving on to the final step. This should be safe to do after about 2 hours.

Step 8. Add Protective Pads To The Bottoms Of The Concrete Coasters

Adding a cork bottom will help prevent scratches on your furniture. Just peel the sticker off of a cork pad and place four of these around the bottom, spacing them equally apart.

You will place them fairly close to the edges, but not right at the edge because then they will be visible.

Now flip them over and enjoy using your new coasters, under your favorite beverage!
