Step By Step Guideline - Tiling Window Recess

Step 1: Remove Casing & Sill

Using a pry bar and hammer, remove the window sill and casing. You may also insert a piece of scrap wood to avoid damaging any surface. 

Step 2: Insulate any Gap

Insulation is an important step! So, now it's time to add some fiberglass insulation into the gaps between the jamb and the wall. However, remember not to hinder the movement of the window sash, especially for double-hung typologies. If you’re also tiling the wall, ensure to add fiberglass drywall tape and compound. 

Step 3: Choose Type of Edging

How would you like the edge of a tiled window? First and foremost, you can set the bullnose on the wall. At this time, let the recess tiles set in first followed by the bullnose on the wall. The second method is to use the corner edging tiles! You can mark the wall where the edges of the corners will fall. Then later, set the wall, then corners and lastly jamb tile. Lastly, you can also apply a decorative border strip around the recess and then apply the bullnose tiles. In this way, you can set the tiles and border prior followed by the jamb tiles.

Step 4: Set Tiles

It’s time to spread and comb the thinset on the sill plate before the sides. Furthermore, you may mortar the jambs and lay the side tiles, holding the entire structure using 8-diameter nails. Lastly, grout these tiles using a float!

Step 5: Add Supports

To ensure the grout lines are straight, install the wall tiles flushed with the jamb. Now set the ceiling tile in mortar paste and support it with three boards or battens to strengthen the structure. Lastly, avoid pushing these tiles too hard into the mortar so they don’t end up dislocating. Yes! Let the mortar dry. 

Step 6: Caulk the Joints

Use a caulk which has the same color as the grout! Now, remember to caulk the joints between the tiles and window to prevent any water damage. Lastly, smoothen the surface using a caulking tool!

Voila! You have just tiled your window recess at home. Yes, it may seem like a tedious task but is definitely fun to DIY!
