drying time should be allowed after placement of concrete before installation of<br />

the flooring.<br />

Particular care should be taken with installations on lightweight concrete. It<br />

always has a higher gross water requirement than ordinary concrete <strong>and</strong> therefore<br />

takes longer to dry. So a longer drying period should be allowed before installation<br />

of flooring. Flooring manufacturers provide advice <strong>and</strong> sometimes also equipment<br />

to test for moisture.<br />

As indication of dryness at any given time is no assurance that a concrete slab<br />

at or below grade will always remain dry. Therefore, protection from moisture from<br />

external sources must be given considerable attention. (See also Art. 3.4.)<br />

Some concrete curing agents containing oils <strong>and</strong> waxes may cause trouble with<br />

adhesive-applied flooring. Commercial curing agents that have been shown to be<br />

satisfactory include styrene-butadiene copolymer or petroleum-hydrocarbon resin<br />

dissolved in a hydrocarbon solvent. These products dry to a hard film in 24 hr.<br />

Parting agents, used as slab separators in lift-slab <strong>and</strong> tiltup construction, may cause<br />

bond failure of adhesive-applied flooring if they contain nonvolatile oils or waxes.<br />

Concrete surfaces that have been treated with or have come in contact with oils,<br />

kerosene, or waxes must be cleaned as recommended by the adhesive manufacturer.<br />

All concrete surfaces to receive adhesive-applied, thin flooring must be smooth.<br />

Also, they should be free from serious irregularities that would ‘‘telegraph’’ through<br />

the covering <strong>and</strong> be detrimental to appearance <strong>and</strong> serviceability. For rough or<br />

uneven concrete floors, a troweled-on underlayment of rubber latex composition or<br />

asphalt mastic is recommended. It can be applied from a thickness of 1 ⁄4 in to a<br />

featheredge. Small holes, cracks, <strong>and</strong> crevices may be filled with a reliable cement<br />

crack filler.<br />

* The adhesives listed are intended for each type of flooring; i.e., asphalt adhesives used for asphalt <strong>and</strong><br />

vinyl tiles are not the same as asphalt adhesives used for wood blocks. There are a number of adhesives<br />

having special properties <strong>and</strong> characteristics, such as heat resistance, resistance to water spillage, <strong>and</strong> brushon<br />

types not included in this table.
