Description

Reinforced polyurethane (PU) flat roof waterproofing system for flat and pitched roofs.


Features and benefits:




  • The embedment and protective coats can be applied by hand using sacrificial brushes and rollers.
  • The mat is highly flexible: Easy to cut, mould and lay with no spring back (even on sharp angles), and has a fast and consistent wet-out speed for rollering of liquid waterproofing components. No fibre wicking will occur.
  • Short curing times allow the product to be quickly over-coated.
  • Highly waterproof.
  • 15, 20 or 25 year waterproofing warranty as standard (depending on film weight of UV coat).
  • 12 year Insurance-Backed or full single-point Latent Defects Insurance Guarantees available at extra cost via installer.
  • BBA certified.

Components (in order of application):




  • Liquasil Ultra PU Embedment Coat: One-component, moisture triggered elastomeric urethane coating, specifically developed to be the first/ embedment coat of a waterproofing membrane for use on roof surfaces. Applied via brush, roller or powered roller.
  • Liquasil Ultra Chopped Strand Reinforcement Mat: Emulsion coated system reinforcement. To be rolled into the embedment coat. Will dissolve after approximately two minutes, allowing free-forming of the mat around to facilitate ease of installation around details.
  • Liquasil Ultra PU UV Coat: One-component, moisture triggered elastomeric urethane coating, specifically developed to be the second, protective coat of a waterproofing membrane for use on roof surfaces.
  • Applied via brush, roller or powered roller.


Surface preparation:



  • Surfaces must be clean, dust-free and dry before application.
  • All chippings, dirt, soil, and fungal growth must be removed from the surface prior to installation, through either power washing or fungicidal wash.
  • Remove any defective coating back to a firm edge.
  • All wood, wood based materials and mortar are to be primed with Liquasil Ultra Primer. Metal surfaces should be primed with Liquasil SWT Corrosion Primer.

Where slip resistant walkways are required, this can be achieved by the application of an extra coat of Liquasil Ultra PU Top Coat incorporating an aggregate.

See manufacturer's literature for further details on installation and surface preparation techniques.
