100% Water Based
Prime Sealer is a highly elastic sealant ( elongation over 500% ) for a perfect seal on any type of porous surface, made with our nanotechnology, and based on our Swiss Formula.
This product is 100% water based and completely ecological.
Prime Sealer is formulated with Nano Acryl GP, our 100% ACRYLIC RESIN WITHOUT STYRENE(**): this ensures total waterproofing and maintains this material property even in the constant presence of water.
Once applied as directed in the application manual, it withstands weathering, contact with acids and temperature fluctuations.
It is ideal for sealing all types of surfaces of materials such as asbestos, cement, brick, asphalt, etc.
10 Year Guarantee
Its proper application, over porous materials, allows for significant economy ( up to 50% ) in the use of NASACOAT® products such as Sun Glare.
Prime Sealer withstands temperatures from -15°C to +80°C.
Consult NASACOAT® technicians for any questions about its use and application.
(**) Common waterproofing products contain acrylic resin modified with styrene. This is not waterproof but water resistant because "waterproofing" containing styrene eventually lets the water through. For this reason, the manufacturers show either on their pails or on the warranty sheet that their products should not be applied on flat surfaces because it does not support the prolonged and constant presence of water. They are merely water resistant.
NASACOAT® coatings are the only ones that can actually guarantee real waterproofing of a flat surface.
