I might be misunderstanding your question. It also can be seen as an indication of the builders insurance against moisture-related issues in the slab. Xypex does not require a dry surface; in fact, a wet surface is necessary. A vapor retarder is a material that reduces the rate at which water vapor can move through a material. Siloxane products may slightly darken the treated surface. It is used to reinforce overlaps of PERMINATOR EVOH. Sodium silicate solutions perform very poorly and ineffective as waterproofing sealers since they have a limited depth of penetration and they are unable to stop or reduce hydrostatic pressure. The ambient air above the sample was 73F and 50% relative humidity. I will always recommend some type of retarder in this situation due to the increased potential for mold and mildew. If you need immediate assistance, please call (800) 342-5976. I dont know what is reasonable concrete cover for slab over vapor RETARDER (not barrier).
