Helpful Tips for Tile Installation
Carefully measure tiles to be cut and mark with a pencil or felt-tip pen. Make straight or diagonal cuts with a wet tile cutter (dry cutting is not recommended - see FAQs), curved cuts with a nipper and full-length curved cuts with a rod saw.
When installing countertop tiles, begin with counter trim, then set full tiles from the first row working back – thus all cut tiles will be placed on the back row against wall.
It is critical that large format tile be installed on a level substrate. Additionally, there must be at least 90% mortar contact and a minimum grout joint of 3/16" depending on the tile.
