A notched
trowel is a tool with a serrated edge used to spread and comb tile adhesive
evenly across the substrate. Notches come in different sizes, and choosing the
right trowel is essential to ensure proper adhesive coverage, stronger bond and
long-lasting installations.
So, which
trowel should you use according to tile size? As a general rule, the larger the
tile format, the larger the trowel notch should be.
