Protection liquid waterproofing Polyurea Rayston X5

Polyurea Rayston X5 is an expandable polyurea applied with a hot spraying machine, it increases its initial volume from 3 to 5 times helping to fill voids and regularize supports. Once cured, it forms a flexible and elastic waterproofing membrane, capable or bridging possible cracks in the support. If exposed, it must be protected with an aliphatic protective finish (Impertrans, Impertrans ECO, Colodur, Impertop Fast 2K, Impermax A). Roof waterproofing applied in two stages, when a solution is needed, simpler, faster, and cheaper than a traditional polyurea system (primer membrane and finish). • Waterproofing of roofs that can’t be visited or with light traffic (limited resistance to punching). • First layer of primer (adhesion and support regulator) for polyureas, when a primer applied at high productivity is necessary. • Comfort layer for floors or continuous sheet for absorbing impact noise. • CE marked EN 1504-2: 0370-CPR-2247 • Asbestos encapsulation certificate (finished with pigmented Colodur or Impermax A) To achieve a good penetration and bonding, support must be: 1. Compact and cohesive (pull off test must show a minimum resistance of 1,5N/mm2). 2. Free of cracks. If any, previous selling is necessary. 3. Clean and dry, free of dust, loose particles, oils, organic residues, or laitance Fibrocement substrates with humidity may require the use of a special primer (H Primer) before application onto them. Support temperature must be between 10ºC and 40ºC. Support moisture must be less than 1,5%.
