• 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
• These surfaces must be jet washed prior to applying the Britannia Aquashield Primer
• 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

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
• Please follow the coverage rates shown in Spreading Rate Section
• Application Temperature should be between 5°C-25°C

Cleaning

• Clean all equipment with water immediately after use and cured coating with white spirit

Shelf Life & Storage

• Up to 12 months if stored correctly in an unopened container
• Store within the temperature range 5°C-25°C

Precautions

• Keep out of reach of children
• In case of contact with eyes wash immediately with plenty of water
• Remove splashes from skin with soap and water or a recognised hand cleaner
• Protect from freezing
• Do not apply paint if there is a risk of heavy rain or frost
• Do not use near fishponds
• Shade variations may occur between different batches
• When completing projects requiring more than one tin ensure they are from the same batch
