Drying Times
Up to 4-7 days depending on temperature, thickness of coating
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
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.
Most roofing substrates to be treated will not normally require priming.
Highly Porous/Friable Surfaces:
Concrete, Concrete and Asbestos Cladding, Sheeting and Guttering should be primed with Britannia Aquashield Primer (see separate technical sheet) prior to over coating with Britannia Aquashield Aggregated Waterproof Roof Coating
All these areas should be suitably prepared and primed as appropriate (see separate technical sheet) before application of Britannia Aquashield Aggregated Waterproof Roof Coating
Non-Porous Substrates:
Slate, Polished bricks should be power washed abraded and completely dry, free from any contamination to achieve adhesion of the Britannia Aquashield Aggregated Waterproof Roof Coating
Bitumen Surfaces:
Discolouration may occur over a new asphalt, tar or bitumen surface; therefore an extra coat may be required, for decorative purposes only
Aged bitumen can be liable to crack, therefore further advice must be taken
Previously Painted or Coated Substrates:
It is good practice to inspect and carry out adhesion tests prior on any existing coating or substrate prior to application of the coating
Splits, Cracks, Joints and Seals:
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 Aquashield Primer
Repair all faults in the surface by either Britannia’s Reinforcing Scrim in the first of two coats or using a proprietary sealer
Crazed Areas:
These should be primed with Britannia Aquashield Primer prior to the application of a coat of Britannia Aquashield Aggregated Waterproof Roof Coating
In areas where excessive movement may occur additional reinforcement must be incorporated into the coating.
Application
To the dry and cleaned surface, apply a generous coat of Britannia Aquashield Aggregated Waterproof Roof Coating by brush, roller or squeegee, at the minimum specified spreading rate as stated above under the heading
