Carpet Squares Over Residual Glue

The first complaint i ever went out on was at a hospital where a custom installation of flooring was failing in all the patient rooms.

Carpet squares over residual glue.

Asphalt based cutback adhesive remaining on a concrete floor after removing old vinyl tile and other flooring represents one of the most difficult and risky subfloors for the installation of new flooring. Use atlas carpet tile adhesive for installations over concrete substrates with up to 85 relative humidity rh current version of astm f2170 and ph of 7 0 9 0. Materials and adhesive must be maintained at 65 85 f and the humidity below 65 for 48 hours prior to during and after the testing and installation. But now that you have ripped up the old carpet you ve got a sticky situation.

The removal of cutback using grinding sanding or blasting may contain asbestos. Dritac eco dribloc can be applied over carpet adhesive residue and asphalt cutback adhesive residue as long as the adhesive ridges and raised residue have been completely removed from the subfloor with only minor stains remaining. All soft loose and raised residue must be removed before encapsulation begins. Care must be taken here as not all patching manufacturers recommend skim coating over all types of adhesive residue.

Don t worry it looks a lot worse than it is. You can t tile over old carpet glue but it s not hard to remove carpet adhesive before tiling. Replacing carpet with tile can give your home an exciting new look. This poses serious health concern.
