Tutorial Steps For Making An Outdoor Concrete Wall Tile With Flowers

Step 1. Cut The Wood For The Concrete Tile Mold

Use a table saw or circular saw to cut the melamine board to approximately 13 x 13”. 

Next, cut 4 pieces of 2 x 2” or 1 x 1”. One piece will be 9”, and three will be 14”.

You are making 3 of the pieces for the side of the mold extra long.

This is to provide you with leverage when you demold the tile.

The extra length will actually overhang the board.

Step 2. Fasten The Sides To The Base

Place the 9” piece on the board so that it is straight. Use the brad nailer to to secure this into place near each end.

Now take the 3 longer pieces and arrange them so that the inside square is 9” around.

Use the framing tool to get everything square. Nail these in with the brad gun.

Step 3. Lubricate The DIY Concrete Wall Tile Mold

Use a rag and paste wax to lubricate the inside edges of the wood sides and then caulk each piece on the inside.

Use your finger to get a nice smooth line, because the caulk will round the edges of the tile.

Step 4. Create The Tile’s Hanging Holes

To create the slots for where the screws will be for hanging the tile, you’ll use straws.

Cut two pieces of straw and fill both ends with hot glue. Now use the paste wax to lubricate the whole straw, including ends. 

Measure and mark 2” in from each side from what will be the top of the tile.

Set these aside for now and keep the ruler nearby.

It turned out that the width of my ruler was a great width to use as a guide for where I would place the straws. 

Step 5. Cast The Outdoor Concrete Wall Tile

Mix the concrete to a soft mud pie consistency and pour it into the tile mold.

Use a flat trowel to level it, as well as lift the board and shake and tap it to help vibrate the concrete to release air bubbles.

Let the concrete set for maybe 20-30 minutes so that it thickens a bit.

This will help keep the straws from pushing themselves out of the concrete.

They will better stay in place with the concrete being slightly set.

Place the ruler across the top inside of the tile and at the 2” marks, insert the straws right at the edge of the ruler.

Be sure that they are flush with the top of the concrete.

The tile will need 24 hours before it can be demolded.

Step 6. Remove The DIY Concrete Tile From The Mold

To demold the tile, use the back of a hammer for leverage and pull up on one or two of the overhanging ends.

These wood sides should come off pretty easily. Now lift the tile out and sand any rough edges with the #200 grit diamond sanding sponge.

Make sure the concrete is completely dry before painting since moisture is still retained in the concrete, and then wait 2 more days before painting. 

Step 7. Print The Flower Design For The Concrete Wall Tile

While the cement is drying, go ahead and print the summer flower design template.

With this printable, you will use transfer paper to trace it in the next step. Just fill out the form to receive the flower design download.

Step 8. Trace The Flower Design Onto The Outdoor Tile

Take the transfer paper and place it shiny side down onto the coaster and tape it in place.

Now take the printable and place it on top of the transfer paper and tape that into place. 

Use a pencil to trace the flowers onto the tile, but check that the design is transferring before tracing the whole design because sometimes more pressure is needed or the paper is upside down.

After the flowers have been transferred to the tile, use the Sharpie Oil Marker to trace over the graphite outlines.

Thicken the lines in some places on the stems, to make them look more natural.

Step 9. Paint The Outdoor Wall Tile’s Flower Design

Sorry- I didn’t get a photo of painting the tile, but it’s the same as what I did here for this coaster.

I recommend painting these in two batches. Start with the blue centers and then once those have cured (after a few hours), then paint the petals. 

Mix the resin at a 2:1 ratio for two minutes. Next, dip a toothpick into the blue colorant.

You only need a tiny bit of color, so one or two dabs of blue will be enough. Let this sit for about 15 minutes so that it thickens slightly. 

If you don’t wait, it will be too runny and spread past the center you painted.

Once the resin starts to mound up a little on the toothpick, then it is ready.

Repeat this process with the white colorant for the petals.

Don’t forget to Pin it for later!
