Description

Roof Primer Coating

Durashield FD Primer is a fast-drying exterior roof primer designed to prime very porous substrates. It should be applied before topcoats of Durashield liquid waterproofing membrane.  

As a solvent-based roofing primer, it comes ready to use and easy to apply by brush or roller. 

Uses of Roof Waterproofing Primer

Durashild FD Primer should be used as a roof primer coating on the following friable and porous substrates:

  • Concrete 
  • Asbestos cladding
  • Sheeting and guttering 
  • Wooden substrates - OSB/plywood
  • EPDM rubber

Primer for Green Roof Waterproofing

In a green roof system, you need to be completely confident in the waterproofing of the substrate. If it is a porous substrate, we recommend applying this primer before the  Durashield  top coat liquid roof membrane. This ensures long-lasting primary waterproofing of your roofing substrate that can then take the green roof system build-up. 

Applying roof primer

Preparation

Make sure you are wearing gloves, goggles and suitable protective clothing. Remove all debris, loose materials and plants from the roof substrate and ensure that outlets and gutters are clear. Using a pressure washer, clean the surface thoroughly to get rid of moss and algae. Once the substrate is clean, you should then dry it. You are now ready to apply the primer coating.

Application

Stir the roof primer well before applying. Consult the manufacturer's technical datasheet for coverage rates and never thin this product.

You can apply Durashield FD Primer by brush or solvent-resistant roller. We recommend working away from the newly coated area and towards your access point. Avoid walking on the newly coated surface whilst application is in progress.

Important note: Never apply in direct hot sunlight, or on frozen or damp surfaces. The temperature needs to be between 2°C and 35°C.

Drying Time   

This roofing primer will be dry under normal conditions in 2 - 4 hrs depending on humidity and temperature. It can be overcoated when dry.
