Which tool is used to accurately transfer an irregular wall profile onto a tile for a precise fit?
Answer: Contour gauge (profile gauge)
A contour gauge has sliding pins that conform to any irregular profile, which can then be traced onto the tile.
What is the recommended notch trowel size for 4×4 inch ceramic wall tiles?
Answer: 1/4" × 1/4" square notch
The TCNA handbook recommends a 1/4" × 1/4" square-notch trowel for small ceramic wall tiles to avoid excessive mortar squeeze-out.
Why is it important to back-butter a tile in addition to troweling the substrate?
Answer: It improves adhesion and helps achieve full mortar coverage on the tile back
Back-buttering ensures mortar bonds to the tile back directly, achieving the minimum 95% coverage required for wet areas.
Which type of grout float is designed to minimize scratching on polished tile surfaces?
Answer: Foam grout float
A foam grout float has a softer surface than rubber and reduces the risk of scratching highly polished or honed tile finishes.
What is the function of a tile nibbler tool?
Answer: Removing small irregular pieces of tile for fitting around obstacles
A tile nibbler uses a punching action to break away small bits of tile, allowing you to fit around pipes, outlets, or curved edges.
When using a laser level during tile installation, what is its primary benefit?
Answer: It projects reference lines that ensure tiles remain straight and level across large areas
A laser level projects perfectly straight horizontal and vertical lines across an entire room, serving as a continuous alignment guide.
