Temperature during application of primer must be above 5oC. Apply a single coat of EasiSeal Pro Primer to the surface with a brush or roller. Follow coverage rate to ensure minimum thickness is achieved. Leave to fully cure, normally overnight, in cold weather it may require 48 hours to fully cure. It is essential that bituminous materials are completely covered with EasiSeal Pro Primer prior to application of EasiSeal Pro. Particular care must be given to rough surfaces such as bitumen felt, where any gaps in primer coverage can lead to product failure. Two coats of EasiSeal Pro Primer are required on uneven surfaces and over waterbased bitumen coatings. Allow each coat to dry fully before overcoating. Continue with the application of EasiSeal Pro Waterproofing Compound as per the Technical Datasheet/ packaging details.
