Q. I plan to install self-stick vinyl tile on a basement floor. I do not believe I have a moisture problem, but I plan to tape two-square feet of plastic down. If the floor is clean and dry, is there any other prep that would be necessary? I have read something about a primer that can be used on concrete. Is this a necessary step?
A. Primer will not be necessary, but you will want to back up the glue with some clear spread adhesive since self-stick tiles do not stick that well. Since this is a peel and stick tile and not a dry back, use a paint roller to apply the adhesive. If it were dry back tile, then the recommended 1/16-inch-by-1/16-inch trowel should be used.
You must let adhesive dry several hours (maybe about eight hours) so the tiles do not slew out of place. Plus, it is easier to work and what seems dry will soon grab the tile. Unless you are applying over existing tile, the self-stick by itself is not substantial. There are arrows going the same direction on back of tiles to keep pattern uniformed.
Tip 1: If you notice that a couple of tile squares back, a gap has mysteriously appeared with gripy type shoe soles, you can apply constant leaning pressure and gradually close up the gap. It takes patience, but you will be glad not to have to look at a less-than-closed joint. If you do need to lift a square in 10 minutes, or 10 years later, use a heat gun or hair dryer but do not over-heat what stays or gets re-used.
Tip 2: The slightest little piece of debris can be like a boulder when it gets under the tile. You can sweep or vacuum the floor and still discover that some small debris was left and gets under the tile. Change the vacuum hose to blow, start in the furthest corner and progressively blow toward the exit. It is the only way to avoid boulders under the tiles.
When making trim fitting, be aware that trim slivers and crumbs of tile can fall into work area and be like boulders under tile. But good grade vinyl tiles have nice looking, durable and easy-care surface. Vinyl squares can be repaired or replaced. Stow several squares for repairs. However, in-laid vinyl requires much skill to fit around object edges. Even well fitted wall edges need shoe molding or will later curl up. In-laid vinyls typically have a soft backing and are easily torn when moving appliances or furniture, and patching will look terrible.
