How to latex a floor
Remove any carpeting or tile.
If you already have carpet or tile on your floor, you will need to remove it before you can examine the subfloor. If the floor is concrete, clear away any furniture or rugs on top of it.
For carpet, you can cut off pieces with an utility knife and pull it up using a pry bar. To remove tile, cut the grout with a utility knife and lift up each piece with a chisel.
