in a straight line. There are several ways to cut tile, click here if you need
To fill pieces near the window
column use a tile snip or Rotozip.
For a small project like this, it is
best to cut and trim each tile to fit. Be sure to leave a
grout gap of about 1/8" around the edges. Now carefully, remove
all the tiles from the sill and set them aside.
Spread the adhesive
The adhesive, known as mastic, goes onto the window sill with the
notched trowel. We used a small "V-notch" for the small 2"
tiles. When applying the adhesive, use the flat edge to apply a layer of
adhesive first. Next, hold the trowel at a 45 degree angle to the wall and
"comb" the mastic out. With less than 10 square feet,
probably cover the entire surface in one pass.
