Instructions for Use
Preparation of Substrate
All surfaces should be thoroughly cleaned to remove dust, dirt and other foreign matter which may affect adhesion.
Wet surfaces should be brushed free from water and wiped with a dry cloth to remove any excess moisture which remains.
Concrete, asbestos cement and other porous surfaces should be primed using FEB AQUASEAL FLASHING & ROOF PRIMER and allowed to dry.
Application
Apply FEB AQUASEAL BITUMEN ROOF REPAIR MASTIC by trowel so that it fills the imperfection and overlaps adjoining surfaces by 50mm (2?) to a thickness of 1.5mm (1/16?).
For cracks exceeding 3mm (1?8?) in width lay a reinforcing strip of metal foil, canvas or thin roofing felt to cover the imperfection allowing a 400mm (1£?) overlap, bed well in and cover the reinforcing strip with a further 1.5mm (1?16?) thick coat of FEB AQUASEAL BITUMEN ROOF REPAIR MASTIC. FEB AQUASEAL BITUMEN ROOF REPAIR MASTIC may be overcoated with other FEB AQUASEAL roofing products. Oil based paint should not be applied over FEB AQUASEAL BITUMEN ROOF REPAIR MASTIC as discolouration will result.
Coverage
(For Guidance Only) 0.7m£ per litre at 1.5mm thickness approx. depending on substrate. Tools should be cleaned with white spirit after use.
