You can easily rout decorative edges or grooves with routers or shapers, but use carbideedged bits. Sawn edges won’t have the same shiny finish as factory edges, so if you can, plan your work so that cut edges will be hidden, and let the smoother factory edge show wherever possible. Sanding isn’t always necessary, especially if you plan to paint, but if you have a rough-cut edge near a highly visible area, use a random orbital sander with 100-grit paper. Belt sanding doesn’t work well because the friction from the belt melts the plastic rather than smoothing it.
Sand down the high spots with a belt sander using a 40- or 60-grit belt. This is a dusty job, so turn off your furnace to avoid spreading dust all over the house, and wear a dust mask. Fill the low spots (1/4-in. ), gaps and seams in the plywood with floor patch (Photo 1). If the plywood is in pretty rough shape, the pros will skimcoat the whole floor with floor patch. This seems like a big job but takes only a few minutes. Andy prefers Ardex Feather Finish but says the products sold at home centers will work too.
Tile your way in cardboard cut witH a utility knife 10 You can cut LVT with just a utility knife. That means you don’t have to run back and forth to a saw every time you need to make a cut. An upside-down tile and a little cardboard make an excellent cutting station. Since all the other tiles rely on the position of the first one, it’s critical that you set the first tile straight (Photo 6). Unlike ceramic tile, LVT tiles stay put, so you can work your way into the room without waiting. When sliding tiles under doorjambs and door trim, lift up on the back of the tile and carefully slide it into place (Photo 7).
