Eagle All Weather Roof Coat is an effective, general purpose roof coating that is resistant to water almost immediately after application, ideally suited for winter use. The solvent based, cold applied bituminous compound contains a small amount of organic fibre to add strength and stability.

Features

• Great for winter use
• Water resistant almost immediately after applying
• Reseals, waterproofs and repairs
• Use on roofs, sheeting, slates and tiles
• Can be applied by brush or by airless sprayer
• Just 2 coats required

Eagle All Weather Roof Coat may be used to reseal, waterproof and repair many different types of roof coverings, including:

• Asphalt roofs
• Built-up felt roofs
• Concrete roof decks
• Asbestos-cement sheeting
• Metal sheeting including iron, steel, zinc and lead
• Slates and tiles

All Weather Roof Coat may be used in conjunction with a rot-proof hessian reinforcement scrim or a bituminised glass fibre scrim, and also as a vapour barrier. All Weather Roof Coat is not suitable for use in silage pits.

Preparation & Application

Apply Eagle All Weather Roof Coat by brush or airless spray, cleaning tools with white spirit.

Stir Well Before Use

The roof must be structurally sound and stable before use; all cracked, broken, slipped or missing slate, tiles, sheets or other forms of covering should be replaced or re-fixed and cracks in felt or asphalt filled before using a roof coating.

Care needs to be taken over preparation of surfaces before application and will influence the degree of adhesion and life of the renovation. All surfaces must be free from oil, dirt, dust and loose debris. All traces of algae and fungus growth should be removed using a stiff brush and the surface treated with a fungicide to kill any remaining spores thereby discouraging the return of any growths.

Asphalt Roofs: Where blisters have occurred, these should be heated with a blow lamp until soft and then smoothed out. If the asphalt is crumbling or badly cracked, it must be removed and replaced with a polyester based underlay. All Weather Roof Coat should be applied by brush in two coats, the first being allowed to dry before the second is applied.

Built-Up Felt Roofs: Remove any loose chippings and carry out the preparatory work detailed above. Minor marks and defects will be effectively filled and covered by All Weather Roof Coat but where these are wider than 0.75mm they should be filled with Trowel Mastic and allowed to dry. Blisters in roofing felt should be opened out, cleaned with a stiff bristled brush and coated with All Weather Roof Coat at 1.5m² per litre. The All Weather Roof Coat should be allowed to set until tacky and then the felt should be re-fixed by bonding it down. In each of the above cases the All Weather Roof Coat and a glass membrane should then be applied.

Reinforced Concrete: Carry out preparatory work. If the deck is new it should be first allowed to cure and then priming using Bituminous Primer at 6-8m² per litre (rate depending upon porosity).

Asbestos-Cement Sheeting: Carry out preparatory work. It is particularly important that the asbestos cement is not saturated with water before protective coating commences. Wait until the asbestos cement sheeting is dry and then apply one coat of Bitumen Primer. Allow the primer to dry and apply two coats of All Weather Roof Coat. Ensure that complete contact is achieved and no air is trapped beneath the All Weather Roof Coat.

Metal Surfaces: Where these show sign of corrosion, such as loose rust, this should be removed by using a wire bristled brush. A rust inhibitive treatment should be applied to ensure that the rust will not return. For normal circumstances, scrubbing with a wire brush is sufficient preparation. All Weather Roof Coat should then be applied in two coats at the rate of 1.5m² per litre per coat.

Slate and Tiles: Carry out preparatory work. The roof should be examined for damaged or loose slates or tiles. Any loose tiles or slates should be re-fixed firmly in place. All Weather Roof Coat and a glass membrane should then be applied.

Scrim Treatment: In order to bridge gaps, cracks and fissures and in all cases where roof surfaces are in advances states of decay, it is recommended that All Weather Roof Coat be used in conjunction with a reinforcing membrane, either rot-proof Hessian or, preferably glass membrane. Having ensured that the surface is clean and receptive to the coating product, apply a first coat at 1m² per litre. Immediately apply the glass membrane into the wet All Weather Roof Coat film using a brush charged with All Weather. Ensure that complete contact is achieved and that no air is trapped beneath the All weather Roof Coat. The glass membrane should be lapped by 50 to 75mm and the inside of each lap should be painted with the All Weather Roof Coat. Small gaps and differences in levels should be bridged ensuring that the glass membrane is not pulled too tightly across the gap so that any movements in the structure will be accommodated. Least 150mm and secure using self adhesive flashing (150mm width) allowing 75mm to be in contact with the brickwork above. Apply a second coat of All Weather Roof Coat and allow this to dry.

Final Surface: It is beneficial to the coating and to the rest of the roof structure to give a final solar reflective finish. An exposed black bituminous surface should be avoided on a pitched or flat roof. When using All Weather Roof Coat a third and final coat should be preferably applied at 1.5m² per litre and, while the film is still tacky well blinded with 1 to 2mm (7 to 14 mesh) stone chippings or clean sharp sand. Alternatively onto the final All Weather Roof coat which should be allowed to weather for a minimum of two weeks, preferably one month, a solar reflective coating can be provided using Solar Reflective Paint.

Vapour Barrier: When insulating material is placed on a flat roof deck it is essential to prevent condensation water vapour from entering the insulation. If this is allowed to happen it can damage the insulation. Two coats of All Weather Roof Coat, the first applied at 1m² per litre, will help prevent this. The All Weather Roof Coat should be applied to the ‘warm’ side, care being taken to avoid pinholes and imperfections in the coating. After the All Weather Roof Coat has dried the insulation may be applied over it.

Coverage

All Weather Roof Coat should normally be applied in two coats at 1-1.5m² per litre depending upon the porosity of the surface.
