The Job Guide
A subway-tile backsplash, set like a pro.
The short answerTo tile a backsplash, turn off the power and remove outlet covers, clean the drywall, and snap a level line. Spread premixed mastic (or modified thinset) with a 3/16" V-notch trowel, set the tile with spacers, and cut around outlets. Let it cure 24 hours, grout, sponge off the haze, then caulk where the tile meets the countertop and cabinets. Most kitchens take a weekend.
A backsplash is one of the most-searched DIY upgrades, and one of the biggest visual returns per square foot. Here's the kit and method for clean, level lines.
