Spreading Rate
These will vary depending on substrate, the site conditions and longevity required.
Typically spreading rates will vary depending on the end use.
As a guide, 1-2 kg/m2 (equivalent to 0.5-1m2)
Coverage will depend on the type and profile of the surface
Drying Times
Dry in 3 hours at 10°C (BS EN ISO 1517 dry surfaces)
Apply in dry conditions at >10°C
Do not apply below 10°C in wet or frosty conditions
Resistant to light showers after 40 mins (on dry surfaces)
Should not be completed in poor drying conditions or when rain is imminent
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 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
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
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:
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 topcoat of Aquashield Eco should then be applied
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 Eco Waterproof Roof Coating by brush or squeegee, at the minimum specified spreading rate as stated above under the heading

Hello. I would like to use Britannia Aquashield Eco to paint a small area of GRP on my boat (above waterline and not walked on/heavily used - purely decorative). What preparation is required, please? Planning to sand GRP, apply a water-based primer (Zinsser Bulls Eye 123 - all products must be water-based) and then paint with Britannia Aquashield Eco. Is primer necessary? Do I even need to sand the surface? What do you advise, please? Thank you.
Answer from Rawlins’ Technical Team:
While Britannia Aquashield Eco can be applied to GRP assuming it is clean, dry, sound and prepared as detailed in the technical data sheet, we would not recommend it for any area subject to foot traffic.
The GRP should be sanded prior to application.

Question:
Is Aquashield suitable as evironmentally, wildlife friendly coating for the wood frame form my raised beds. I am using old wooden wardrobes an they have a varnish on them.
Answer from Rawlins’ Technical Team:
This product is designed for application to roof and not timber surfaces, so will not be suitable for this application.
The lifespan of the timber and paint in this application is difficult to predict as ideally you would use treated timber for raised beds.

Question:
Is Aquashield Eco for professional use only - (though, since I built the garage I intend to use it on, would I be classed as Professional, anyway?) Can this product be used to coat the existing torched-on felt flat roofing? Is the adhesion to cleaned roofing felt good without the use of any primer? Many thanks.
