Use Gripset XpressLay Self Adhesive Waterproofing Sheet for: Rapid and reliable waterproofing of internal wet areas, and providing anti-fracture protection under tiled surfaces.
Gripset XpressLay Self Adhesive Waterproofing Sheet is a high-strength, reinforced PVC sheet designed for efficient waterproofing and anti-fracture applications. Its self-adhesive backing significantly speeds up installation, making it a preferred choice for tilers and waterproofers. This sheet provides excellent moisture and vapour resistance, safeguarding internal wet areas like bathrooms and laundries. For renovators and builders, its anti-fracture properties offer added protection to tiled surfaces over existing or cracked substrates. The versatility of Gripset XpressLay extends to various substrates, including concrete, timber, and existing tiles, streamlining material selection on site.
Primer Information: Gripset XpressLay requires priming for optimal adhesion. Use RLA Universal Primer (diluted for porous surfaces, neat for non-porous) or Gripset E60 for green/damp surfaces. Priming ensures a strong bond, especially crucial for demanding wet area applications.
Installation: The self-adhesive nature of XpressLay allows for quick and easy installation. Simply measure, cut, peel, and stick. Ensure overlaps are a minimum of 50mm and firmly rolled. For plumbers and tilers, this significantly reduces installation time compared to traditional methods.
Thickness and Strength: At 1mm thick with a tensile strength of >2MPa and elongation of >60%, XpressLay provides a durable and flexible waterproofing layer. This is vital for preventing cracks in tiles due to substrate movement, a common concern for builders and homeowners.
Waterproofing Performance: Gripset XpressLay boasts excellent waterproof and vapour resistant properties with a water vapour transmission rate of 0.1g/24h/m². This effectively protects structures from moisture damage, meeting the stringent requirements of AS4858 for internal wet areas.
