Rapid curing and highly flexible PMMA (polymethyl methacrylate) surface waterproofing resin for horizontal areas.

Jump to:
+44 (0)330 058 0668 www.soprema.co.uk

Application

To be applied only to prepared substrates.

  • It is applied along with Alsan Fleece P reinforcement for waterproofing large areas, and for the waterproofing of joints on water impermeable concrete (flat roofs, car parks/ parking decks, balconies, terraces, walkways etc).
  • For accessible areas, the Alsan 770 waterproofing membrane is applied in combination with surfacing finishing products from the Alsan range or other finishes (e.g. tiles).

Description

A high‐performance, PMMA (polymethyl methacrylate) based waterproofing resin with low‐temperature flexibility. The resin is used in conjunction with reinforcement fleece, to create a seamless, durable and reliable waterproofing membrane. It can also be used to waterproof movement joints. Can be used with Alsan 070 catalyst.

Features and benefits:

  • Highly flexible and crack‐bridging even at extreme sub‐zero temperatures.
  • Permanently weather‐resistant.
  • UV, hydrolysis and alkali-resistant.
  • Watertight and fully bonded to the substrate, therefore no water ingress.
  • Easy and fast application via sheepskin roller or brush.
  • The most complex roof penetrations can be securely incorporated into the seamless waterproofing system.
  • Fast‐curing.
  • Can be applied to almost all substrates, including substrates of variable materials (in combination with either Aslan 170 or Aslan 172 primer).
  • Solvent‐free.

Applications:

To be applied only to prepared substrates.

  • It is applied along with Alsan Fleece P reinforcement for waterproofing large areas, and for the waterproofing of joints on water impermeable concrete (flat roofs, car parks/ parking decks, balconies, terraces, walkways etc).
  • For accessible areas, the Alsan 770 waterproofing membrane is applied in combination with surfacing finishing products from the Alsan range or other finishes (e.g. tiles).
