Surface preparation

Surfaces should preferably be as dry as possible. Emergency patch repairs can however be successfully completed to surfaces with running water. Remove any loose material and dirt. Very porous, dry surfaces should be primed with Watco Roofite diluted with 25% white spirit. A wire brush should be used to remove all traces of moss etc. A fungicide may be required for heavily contaminated surfaces. Specialist advice must be sought when dealing with old asbestos/cement roofs.


The coating should be applied generously by brush at the rate of 1m² per kilo. If a second coat is required it should be applied at right angles to the first coat. Do not brush out to a thin film. Cracks, splits, holes and leaks around roof sheet overlaps should be treated in the following manner.

Apply a generous coat of Watco Roofite and immediately bed in a strip of Watco Scrim cut to a suitable size. Apply a further coat of Watco Roofite over the scrim using a stippling action and leave to cure. Deep pits and cracks in flat concrete roofs etc can be filled with a mortar consisting of Watco Roofite mixed with Roofite Additive. The surface should be primed first with Watco Roofite before trowelling in the Watco Roofite and additive mix.

In exceptional temperature conditions advice should be obtained from Watco’s Technical Department.
