Application
Can be applied conventionally by brush, roller or spray equipment. It is recommended to apply first coat by brush to obtain optimum adhesion. DRYTEX VASTAF PW400 Waterproofing Membrane has excellent high build properties, and can be built up to 2000 micron wet in one application. However from a curing point of view and dependant on weather conditions at the time of application, it is more pertinent to apply and build up the membrane in two or more coats, to allow quicker cure in each stage. The thicker the application the longer the cure.
