Part of the Durashield Waterproofing System, this FD Primer is developed for times when priming and topcoat needs to be done in one day. Typically drying within 2-4 hours, this primer will penetrate porous substrates with ease.

Features & Benefits

  • Allows priming and top-coating in one day.
  • Rubber solvent-based primer.
  • Fast drying.
  • Penetrates porous substrates.
  • Rainfall immediately after application has no adverse effect.
  • Clear in colour.


Ensure the substrate is free from old plant and debris and cut all brick chases if required. The outlets and gutters must be free from obstruction.

Clean the surface with a powerwash of up to 2,000 psi, depending on the substrate. If needed clean the area with Britannia Fungicidal Wash. This eliminates all moss/algae. The wash must be applied and left on the substrate for 7 days, then washed off prior to the application. The substrate must be dried off using squeegees/rags. Gas guns should not be used. Once the substrate is clean and dry you can then begin the application.

Repair faults in the surface by using a high quality waterproof mastic/filler. Apply Durashield FD Primer followed by Durashield Waterproofing System to repaired areas incorporating Britannia Reinforcing Scrim overlapping by 5cm.


Important information

Do not thin. Stir well before use as separation could occur. Do not apply in hot direct sunlight or coating may skin. Do not use on new bituminous primers, coatings or surfaces. Cannot be used as a topcoat.

To the dry and cleaned surface, apply a generous coat of Britannia Durashield FD Primer by brush or roller at the specified spreading rate as stated under the heading. The substrate and ambient temperature for the application of the system must be between 2°C and 35°C. DO NOT APPLY to frozen or damp surfaces. Work away from the area immediately being applied and toward a suitable escape access. Do not walk on newly coated surface whilst application is in progress. For cleaning equipment use Britannia White Spirit.
