These will vary depending on substrate, the site conditions and longevity required.
Typically spreading rates will vary depending on the end use.
Standard Coat - Approximately 1 kg per square metre dependent on substrate
High Build Coat - Between 1 kg – 2 kg per square metre dependent on substrate
Drying Times
Up to 6-7 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
Dirt build up, moss and loose material should be removed by scraping or brushing. In cold conditions any ice present on the surface must be removed.
Most roofing substrates to be treated will not normally require priming
Application Temperature should be between 5°C-25°C
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 Smooth Waterproof Roof Coating
Fibrous cement, corrugated cladding, sheeting and guttering: other than repairs, we recommend the use of Durashield for this application
Metal Surfaces:
Ferrous-new, weathered and previously painted galvanised iron and steel
All these areas should be suitably prepared and primed as appropriate (see separate technical sheet) before application of Britannia Aquashield Smooth 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 Smooth 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 on any existing coating or substrate prior to application of the coating
Splits, Cracks, Joints and Seals, Crazed Areas:
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
Surface Faults:
Repair all faults in the surface with either Britannia’s Reinforcing Scrim in the first of two coats or using a proprietary filler
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 Smooth Waterproof Roof Coating by brush, roller or squeegee, at the minimum specified spreading rate as stated above under the heading
