Finish TradesQuestion 278 of 700
A vinyl composition tile (VCT) floor is being installed and will be maintained with floor finish. The subfloor must be smooth because:
a.VCT is thick enough to hide any bump
b.Thin VCT telegraphs (shows) subfloor irregularities and holes through the surface
c.The finish coat fills all holes
d.Roughness improves adhesion of VCT
Explanation
Because VCT is thin, any bumps, gouges, or holes in the subfloor telegraph through and show in the finished floor, so the substrate must be patched smooth and clean. VCT does not hide bumps, floor finish does not fill substrate holes, and roughness harms both appearance and adhesion.
