Surface Preparation

Make sure the surface is free of all debris, such as nails, screws or any other construction rubbish that may damage the product once the floor finish is applied on the product. Generally, a good cleaning is enough to prepare the surface. Also make sure that there are no gaps between the two floor support panels. If necessary, fill those gaps with acoustic sealant.

The same preparation as for the wood deck should be performed, but since this product is a vapour barrier, you must also make sure that the concrete deck does not have a moisture rate so high that the product traps the moisture in the concrete. A maximum moisture content of 3 lb/1,000 ft2/24 h (1.46 kg/100 m2/24 h) is recommended. This reading can also be taken with a calcium chloride test.
