Some interesting tile tidbits for you today:
–A wet piece of tile that is still dripping when removed from the wet saw will interfere with the mortar bond.
–‘Keying in” tile is covering an area with thinset with the flat side of a notched trowel before tile is placed. A trowel with notches impregnates the substrate with setting material; and thinset bonds to itself really well.
–For proper installation, trowel in one direction at a 45 degree angle, and as you place the tile, press it forward then pull it back to ‘burp’ out any air that might interfere with the bond in the future, as you collapse the ridges the notch trowel has made.
–For appropriate trowelling, 80 percent coverage is necessary. ‘Five-spotting’ just won’t do.
–Only cement-based setting materials can be used in a wet area.
–All installations need movement joints.
–The minimum grout joint for tile is 1/16″. Large format tile and offset patterns must have larger joints.
–Large format tiles require a substrate that is twice as flat (no more than 1/8″ variation from plane in 10 feet).
–Grout joints up to 1/4″ allow for 1/32″ of lippage (variation in the height of adjoining tiles).
–You need 3 times the facial dimension variation of the tile for minimum grout joint width.
–Wall-wash lighting can be a problem unless it’s out 24″ from the wall because no tile is perfectly flat.
–Too much sealer can cause hazing on the surface, damage, or change the color of your installation.
