BITUPROOF.

DESCRIPTION. A bitumen emulsion of medium brushing consistency

USES. For use as a waterproofer for most roofing surfaces, as a protective coating for metal and as an insulator (providing a barrier against vapour loss).

APPLICATION. Following recommended preparation. Apply two coats by brush. In areas likely to be by expansion and contraction, reinforce with an open woven glass fibre membrane and apply a further coat. Not suitable for use if there is an imminent threat of rain.

DRYING TIME. Under normal conditions, 4 - 6 hours, but allow 24 hours between coats.

COVERAGE.  1.4 square metres per litre per coat.

SIZES. 25 Litre, 5 Litre Tins.

WATERPROOFING.  Always ensure the appropriate waterproofing product has been selected. Water based emulsions can be applied to substrates that are slightly damp whereas generally based solvent solutions need a totally dry surface. Avoid the use of emulsions if there is an imminent threat of rain, however a solvent based product such as RUFABRUSH can be used even where there is a likelihood of either rain or frost as it becomes water resistant quickly after application.

Most jobs will require two coats, with the second coat being applied at right angles to the first. These coats should not be applied too thickly and care should be taken not to allow the coating to collect at the bottom of corrugated gullies as this may result in blistering when it has fully dried. Waterproofing should extend up any adjoining vertical surface to approximately 200mm (8"). Always ensure that the roof/wall angle has a continuous coating.
