<br />B. Concrete Subfloors: Verify that concrete slabs comply with ASTM F 710 and the following:
<br />1. Slab substrates are dry and free of curing compounds, sealers, hardeners, and other materials
<br />that may interfere with adhesive bond. Determine adhesion and dryness characteristics by
<br />performing bond and moisture tests recommended by carpet tile manufacturer.
