Step One: Assess the Wall and Window Edges

Your first task should be to assess the wall and window edges for weak spots. To do this, start by taking a small piece of wood and taping it to the part of the wall you want to tile. This will expose any lumps or bumps that can get in the way of the process.

Once you’ve identified parts of the wall that are weak or irregular, use a scraper, a hammer, or a chisel to level the surface of the wall. Clean up any loose chippings with a vacuum.

Note: If you’re using drywall, you’ll need to ensure it’s resistant to moisture. Assess the surface carefully, and make sure that all the joints between the boards aren’t exposed. To do this, make sure you cover each one with tape and plaster.

Now you’ve evened out your wall and cleaned up the mess you’re ready to start the tiling process. When you tile a window with trim, the trims act as a support system to keep the tiles balanced and prevent them from moving.

Without trim, it’s advised that you use a mix of plaster and concrete to mimic this system. It will also make the process of attaching the tiles to your wall much quicker and easier, and prevent a build-up of excess dirt and debris from occurring.

Step Two: Priming

Now it’s time to prime. The easiest way to do this is to fill up a spray can with your primer and dilute it lightly with water. Once the mixture is diluted, you can begin spraying it directly onto the window frame and the edges of the surrounding wall.

By spraying primer on the walls and the window frame, you can ensure that the application process is more manageable. Primer will also prevent the risk of rust buildup, improving the longevity of your windows.

Step Three: Mix Your Concrete

Once the surface is primed, you can move onto the next steps. First, you’ll need to mix your concrete, either by hand or machine.

To do this, stir your chosen mixture together for a minimum of three minutes or until it reaches a thick consistency. If you’d prefer not to use concrete, you can opt for a thin-set powder like mortar powder.

Step Four: Attach Your Wooden Planks

To ensure your tiles are attached evenly, you’ll need to use a guide. Grab your wooden planks and a drill, and attach one to the bottom end of the window frame.

This will also ensure your concrete or mortar powder is poured evenly. Once the plank is secured, go ahead and apply your concrete.

Step Five: Prepare and Apply Your Plaster

Now the concrete is in place you can start to prepare and apply your plaster. Remember: plastering can get messy, so move any obstructions out of the way first. To avoid contamination, use a clean bucket and follow the manufacturer’s instructions for mixing plaster.

Once your mixture is prepared, start applying the plaster around the border of the window – this will act as a replacement for the trim. Now, apply mesh to the plaster, and smooth the edges down.

Plaster mesh will improve structural integrity, prevent cracks, and create a stronger bond.

Step Six: Remove The Wooden Panel

When the concrete and plaster have completely dried, you can begin removing the wooden panel at the bottom of the window frame. Once the frame is removed, you will probably find holes in the wall that need to be filled.

You can do this by applying any leftover plaster or concrete to the cracks. To distribute weight evenly, you should only use concrete at the bottom of the window, and plaster should be applied around the edges.

Step Seven: Attach your Tiles

If you’ve made it this far, congratulations! We’re now at the final part of the process. Once the concrete and plaster have dried and you’ve removed all other materials out of your way, you can start attaching your tiles.

First, make sure you attach your adhesive to the back of each tile. Once the adhesive is in place, you can begin attaching your tiles one by one to the window frame. As the wall has already been plastered, there should be no lumps or bumps, and the tiles should go on evenly.

If they don’t, remove the tiles and scrape off any protruding bumps or edges. Once your tiles are attached to the wall, use a leveler to check they’re evenly secured to the masonry.
