Preparation

Clear all areas of moss, lichen and debris by brushing or power washing and remove surface water and any contamination such as Oil or Grease and allow to dry. Apply Britannia Fungicidal Wash to prevent further fungal/algal growth.

• Stir well before use
• Do not thin

To the dry and cleaned surface, apply a generous coat of Britannia Durashield FD Primer by brush or roller (solvent resistant), at the minimum specified spreading rate. The substrate and ambient temperature for the application of the system must be between 5°C – 30°C.

Felted surfaces, fibrous cement corrugated cladding, sheeting and guttering should be primed with Britannia Durashield FD Primer.

Fibrous cement corrugated sheeting: two coats of Durashield FD Primer must always be applied to this substrate.

OSB/Plywood, wooden substrates and insulation boards must be primed with Britannia Durashield FD Primer and fully scrimmed with the built-up system (wet on wet).

Pay particular attention to clean out any splits/cracks/joints and seals by scraping or brushing off with a stiff bristle brush before applying the Britannia Durashield FD Primer. Repair all faults in the surface by using a proprietary filler.

Repair all faults in the surface with either Britannia’s Reinforcing Scrim in the first of two coats or using a proprietary filler.

Application

• After the drying of the primer, embed the reinforcing scrim into the wet Durashield basecoat applied at a rate of 1 litre/m², whilst avoiding creasing
• Adjacent lengths of the reinforcement must overlap by 50mm
• Finish with a further coat of Durashield as a topcoat at a rate of 0.5 litre/m² ensuring that the reinforcement scrim is completely encapsulated
• The substrate and ambient temperature for the application of the system must be between 5°C – 30°C
• Final drying time is up to 1.5 hours or overnight depending on temperature and conditions
• Note: DO NOT APPLY to frozen or damp surfaces
• Note: DO NOT APPLY in hot direct sunlight or coating may skin. 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
