Thompson's One Coat Roof seal is a modified bitumen coating developed to give lasting weatherproofing protection to a variety of roofing materials in a single coat.
The one coat formulation cures to form a flexible membrane that flexes with the natural movement of the roof resisting cracking and splitting.
Added fibres give superior tensile strength and crack bridging qualities ensuring complete weatherproofing protection in a single coat. Developed for application to damp surfaces the one coat formulation protects against light rainfall in minutes, giving immediate weatherproofing protection.
Suitable for use on a variety of roofing materials, roofing felt, asphalt, tiles, slate, corrugated metal, bricks, concrete and wood.
Ideal for use over flashings and in roof valleys.
