Smooth, cold applied rubber based waterproofing topcoat for a longer lasting seamless coating.

Just one coat over primed surfaces.

Advantages

  • Exceptional durability and performance up to ten years
  • Cold applied - no hot works on roof
  • Ready to use
  • Works instantly
  • A single coat system developed over primed surfaces for larger-all-over roofs where greater life expectancy is needed
  • Flexible, highly elastic solvent-based single pack coating with excellent adhesion to almost any wall or roof substrate
  • Rainfall immediately after application has no adverse effect
  • Excellent UV and resistance to movement of the substrate
  • Fast curing, can be applied at low temperatures

Colours

Grey, Black and Solar Reflective White.

Pack Size

5 and 20 litre containers

Suitable Substrates
  • Ready for use on all Primed Surfaces: Flat Roofs, Pitched Roofs, Weathered Asphalt and Bituminous Surfaces, Gutters, Concrete, Brickwork, Fibreglass and GRP, Felted Surfaces, Fibrous Cement Corrugated Cladding, Sheeting and Guttering, Metal (Galvanised, Ferrous and Non-Ferrous), Old Lead, Existing Painted Surfaces and EPDM.
  • OSB/Plywood and Wooden Substrates (must be taped and fully scrimmed and an additional coat of Durashield added) - see Typical Spreading Rates.
  • Fibrous cement corrugated sheeting and skylight surrounds must be reinforced with scrim to laps and around ALL fixings (see Scrim Recommendation).
  • Can be roller or brush applied.

Not for use on Walkways, Balconies, tanking, fish and aquatic ponds, plasticised PVC (Plastisol) new lead, slate or internal use.

DO NOT USE ON NEW BITUMINOUS PRIMERS/COATINGS OR SURFACES.

Repairs to Substrate

Including splits, cracks, joints, seals and crazed areas.

  • Repair faults in the surface by using a high quality waterproof mastic/filler.
  • Apply Duraproof system to repaired areas incorporating Reinforcing Scrim overlapping by 5cm.

Scrim Recommendation

  • Apply Reinforcing Scrim to all areas which can be ponded.
  • Reinforcing Scrim must be used on all upstands, curves, skylight bases and rainwater outlets.
  • Reinforcing Scrim to be used on all gutter expansion joints.
  • Reinforcing Scrim to be used on all repaired areas.

For fibrous corrugated concrete sheeting and skylight surrounds:

  • Apply to both horizontal and vertical laps including around ALL fixings. Before starting, carefully tighten any fixings that may be loose.
  • When reinforcing the horizontal laps, ensure the reinforcement follows the profile of the sheet exactly, eliminating any possibility of air pockets being trapped under the reinforcement.
  • Any cracking within the sheets should also be reinforced.
  • Finish with an additional coat of Duraproof over the scrimmed area.

Priming

All roof substrates require priming with Duraproof Primer before over-coating with Duraproof. See Primer Guide for the following substrates.

These surfaces should be cleaned prior to applying Duraproof:

  • Highly Porous/Friable Surfaces: Felted surfaces, fibrous concrete corrugated cladding, sheeting and guttering should be primed with Duraproof Primer (see separate technical data sheet).

  • Fibrous concrete corrugated sheeting: Two coats of Duraproof Primer must always be applied to this substrate.

  • Concrete & Masonry: Prime with Duraproof Primer.

  • OSB/Plywood & Wooden Substrates: OSB/plywood, wooden substrates and insulation board must be treated with a 50mm wide strip of tape (any other tape must be adhesion tested before use). A continuous surface should be created before commencing with the application of Duraproof Primer (see separate technical data sheet).

  • Weathered Asphalt & Bituminous Surfaces: Prime with Duraproof Primer. Note: discoloration can occur over Weathered Asphalt or Bituminous Surfaces. An extra coat may therefore be required for decorative purposes. Do not use on new bituminous primers/coatings or surfaces.

  • Metal: All ferrous metals should be primed with Metal Primer (see separate technical data sheet).

  • Lead: No primer required on old lead, sheet/valleys. Do not use on new lead.

  • Aluminium, Copper & Galvanised Steel: These should be primed with 1 Pack Etching Primer (see separate technical data sheet).

  • Fibreglass & GRP: Prime with Duraproof Primer.

  • Previously Painted or Coated Substrates: Prime with Duraproof Primer.

  • EPDM: Prime with Duraproof Primer. Note: It is good practice to inspect and carry out adhesion tests on any existing coating or substrate prior to application of the coating.

Drying Time

Duraproof Primer can take up to 1 day to cure but can be over coated when dry.

Duraproof Topcoat:

Surfaces must be COMPLETELY DRY prior to application of Duraproof.

  • Up to 8 hours or overnight depending on temperature and conditions.
  • Full cure: up to 7 days.
  • The product may remain slightly soft for a further period depending on climatic conditions; this is not detrimental to the waterproofing qualities of the product.
