Installation of floorcovering article on chemically abated flooring surface and composite article

A process for decreasing the rate at which abatement chemical migrates from concrete and into a floorcovering article comprising the following steps:

• (a) Providing a flooring surface having a mastic material thereon;
• (b) Applying at least one natural-based abatement chemical to the mastic material on the flooring surface;
• (c) Agitating the at least one abatement chemical into and/or onto the mastic material of the flooring surface to form a chemically treated pre-abatement flooring surface;
• (d) Allowing the chemically treated pre-abatement flooring surface to rest/soak for a period of time;
• (e) Removing at least a portion of the chemically treated pre-abatement flooring surface to form a chemically abated flooring surface;
• (f) Applying a polymer-containing barrier material to at least a portion of the chemically abated flooring surface to form a chemically abated flooring surface containing a barrier coating thereon, wherein the polymer-containing barrier material comprises a mixture of:
• (i) an acrylic material,
• (ii) a first kaolin-based pigment having a plate-like morphology, and
• (iii) a second pigment that differs from the first pigment;
• (g) Applying a floorcovering article to the chemically abated flooring surface, wherein the floorcovering article contains at least one adhesive material, wherein the at least one adhesive material is in physical contact with the barrier coating of the chemically abated flooring surface and is comprised of an acrylic emulsion;
• and
• (h) Analyzing the floorcovering article using headspace solid-phase microextraction gas chromatography-mass spectrometry-flame ionization detection (SPME-GC-MS-FID) to measure the decreased rate that the abatement chemical migrated from the concrete into the floorcovering article.
