This Fastrack Liquid is a quick drying moisture suppressant product which is effective against rising damp and construction moisture. The standard procedure using a two-part system is drastically more hazardous and complex, this product is a great solution. Just a 0.2mm coating will provide an effective moisture barrier for your new hardwood flooring. Following the application, you will be able to lay your brand new flooring after just 30 minutes, after which it will have turned from blue to a clear film. Each 5 litre bottle covers approximately 5 metres square with the necessary 0.2mm film thickness. Stir before use.
