The membrane is easily and consistently applied to any shape of roof or balcony, and vertical and horizontal surfaces, including drains and upstands. Maclennan applied Polyprufe Waterproof Coating system is a long-lasting, reliable seal which is resilient, protecting against water leakage, garden chemicals and oil spillages, mineral residue leaching, and resisting root penetration. Even at low temperatures (0°C/32°F and rising), It can be ready for use within hours of application, and tough enough to withstand full construction traffic without any need for protection boards. The Maclennan applied Polyprufe Waterproof Coating system is impermeable to water with long-lasting protection.

Other key benefits:

  • Seamless membrane safeguards against water leakage.
  • Durable wear coat protects against damage.
  • Provides up to 2.5mm/100mils crack bridging ability onto a variety of prepared substrates.
  • Localized repairs can be made without removing the whole membrane.

Polyprufe Waterproof Coating system can be applied in temperatures of 5°C/41°F and above. Its wear coat prevents physical damage during installation of the garden and reduces the need for subsequent protective layers. Unlike sheet membrane this seamless, single fully-bonded elastomeric membrane is supplied in liquid form, hence cannot be punctured during storage prior to use. The membrane, applied by spray or hand, creates no noxious odours to disturb current building tenants, and does not require the use of naked flames or hot kettles, naked flames or solvents.
