Ceramic tile is a gorgeous floor covering and, believe it or not, can be installed directly over a vinyl floor. It's easy! First, use a belt sander to clean and score the vinyl. Next, apply two coats of bonding agent. This will help the mortar to stick to the floor. As with any tile job, the most important step comes next -- layout lines. Always start laying tile from the center of the floor and outward toward the edges. Keep it simple, and use premixed mortar. Work on small areas at a time. A day of drying is needed before applying grout. Once grouted, a light vinegar wash will make your job shine. You won't believe the difference. And that's the On The House tip for today.
