ProTXcoat 754RB Membrane

Solvent based rubberized acrylic roof coating

ProTXcoat 754RB is a single component solvent based rubberized acrylic waterproof coating. The product is supplied ready to use and is ideal for water proofing roofs, gutters and fibreglass in colder climates (product cures at 5°C/ 40°F).

The product has been developed using a complex range of acrylic resins, fillers and polymers which combine to provide a high performance waterproofing membrane with long term UV stability.

  • UV stable membrane for roofs and GRP structures
  • Seamless & flexible waterproofing system
  • Single component
  • Cures at temperatures as low as 5°C/ 40°F
  • Shower resistant within 15 minutes

Typical applications

Suitable for coating the following surfaces – Roofs, gutters, fibreglass structures

TECHNICAL SPECIFICATIONS

ProTXcoat 754RB is ready for use on flat roofs, pitched roofs, weathered asphalt, bituminous surfaces, concrete, brickwork, fibreglass, felt, metal, plywood and wooden substrates.
All surfaces have to be cleaned appropriately and must be free from mould, moss, algae, dust and debris. The surface of the roof must be pressure washed at a minimum 2000psi. The roof surface must be dried off using squeegees or allowed to dry overnight.

  1. Concrete and porous surfaces
    All surfaces must be primed using ProTXcoat 302 SPEP a low viscosity epoxy primer applied at a wet film thickness of 150 microns (6mil).
  2. Plywood and wooden surfaces
    All surfaces must be primed using ProTXcoat 302 SPEP a low viscosity epoxy primer applied at a wet film thickness of 150 microns (6mil).
  3. Bituminous or asphalt surfaces
    All surfaces must be primed using ProTXcoat 389 APBP Primer a low viscosity solvent based acrylic primer applied at a wet film thickness of 100 microns (4mil).
  4. Mineral Felt surfaces
    All surfaces must be primed using ProTXcoat 389 APBP Primer a low viscosity solvent based acrylic primer applied at a wet film thickness of 100 microns (4mil).
  5. Metal surfaces
    All surfaces must be primed using ProTXcoat 306 A-prime a low viscosity solvent based epoxy primer applied at a wet film thickness of 150 microns (6mil)

Prior to mixing please ensure the following:

  1. The base component is at a temperature between 15-25°C (60-77F°).
  2. The ambient & surface temperature is above 5°C (40F°).
  3. The ambient & surface temperatures are not less than 3°C (6°F) above the dew point.

Once these 3 checks have been met, please proceed with mixing the product.

  1. 554 RB Membrane is a single component material.
  2. Agitate the product using an electric paddle mixer to ensure you have a consistent mix of acrylic emulsion.

Brush or roller applications

  1. Apply the 1st coat of material using a medium pile roller at a wet film thickness of 750 microns (30mil).
  2. While the coating is still wet lay 100gm glass fibre chop strand matting onto the surface.
  3. Back roll a thin layer of 754 RB membrane onto the surface to ensure the matting is fully encapsulated.
  4. Allow to cure for approximately 8 hours (20°C/ 68°F).
  5. Apply a 2nd coat of ProTXcoat 754RB at a wet film thickness of 750 microns (30mil).
Coverage Rates5ltrs (1.3 US gallon) of fully mixed product will give the following coverage rates
