Britannia Aquashield Eco is an excellent waterproof coating that is suitable for general maintenance work. Only one coat is required, and this will provide a durable water-resistant finish. The coating is a water-based elastic acrylic coating that is eco-friendly. Ready for use on flat and pitched roofs, weathered asphalt and bituminous surfaces, gutters, concrete, brickwork, GRP and fibreglass, felt and metal (galvanised and ferrous).
Features & Benefits
- A water-based highly elastic acrylic coating.
- Dries to form durable and water-resistant finish.
- Low odour.
- Safe and eco-friendly.
- Solvent-free.
Preparation & Application
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. To the dry and cleaned surface, apply a generous coat of Britannia Aquashield Eco Waterproof Roof Coating by brush or squeegee, at the minimum specified spreading rate as stated above under the heading. Application Temperature should be between 5°C-25°C.
Substrate Types
Highly porous/friable surfaces: Concrete and Asbestos Cladding, Sheeting and Guttering should be primed with Britannia Aquashield Eco Waterproof Roof Coating thinned 10% with water prior to overcoating with a second coat of Britannia Aquashield Eco Waterproof Roof Coating. These Surfaces must be jet washed prior to priming.
Fibrous cement corrugated sheeting: two coats of Aquashield Primer must always be applied to this substrate.
Metal surfaces: Ferrous-New, Weathered and previously painted galvanised iron and steel. Non-Ferrous Metals - Aluminium sheeting & Aluminium Alloy Box gutters and previously painted non-Ferrous Metals. All these areas should be suitably prepared and primed as appropriate (see separate technical sheet) before application of Britannia Aquashield Eco 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 Eco Waterproof Roof Coating.
Bitumen and asphalt surfaces: Can be used as an isolator over new asphalt, tar or bitumen surfaces. Aged bitumen can be liable to crack and therefore further advice must be taken.
Splits, cracks, joints, seals and crazed areas: These should be cleaned out with either a scraper or a stiff bristle brush and primed before applying Aquashield Eco thinned down 10% with water. A top coat of Aquashield Eco should then be applied.
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.
Previously painted or coated substrates: It is good practice to inspect and carry out adhesion tests on any existing coating prior to application of the coating.
In areas where excessive movement may occur, additional reinforcement must be incorporated into the coating.
It is your responsibility to read the Product Data Sheets (available below) before you place an order and prior to application of the product. The content of this website is our best recommendation and is not advice. Coverage rates quoted are approximate, you agree that coverage depends on the condition of the substrate, surface absorption, texture and application method. We ALWAYS recommend a trial area is coated to ensure the product meets your requirements before use.
