• METHOD OF USE Apply by stiff brush, mop or squeegee. Preparation Ensure that the surface to be repaired is dry and clean, i.e. free from all loose debris, rust, dirt and grease. All traces of algae and fungus growth should be removed using a stiff bristled brush. Where algae and fungi have been present, remove all traces completely and treat the surface with Fungicide in order to kill any remaining spores, thereby discouraging the return of the growths. In general the felt laying techniques employed should be those detailed in BS Code of Practice 144 Part 3 1970, Clause 4.6. Certain types of felt (particularly organic fibre reinforced felts: type IF BS747) should be prepared for laying by first cutting into convenient lengths (5 metres) and leaving these sections laid flat and weighted down for 24 hours. The FELT ADHESIVE should be brush applied to the surface and left "open" for 15 to 30 minutes (depending upon drying conditions) in order to develop its full tackiness. The felt should be placed into the wet adhesive film carefully, rubbing or rolling each section down to ensure maximum contact with the adhesion and ensuring that all air has been excluded. Whenever possible, the felt should be unrolled into the FELT ADHESIVE and rolled home with a light roller (approx. 25 kg, 55 lbs). Lap Cement: Laps at the edges should be at least 75 mm (3") wide and laps at roll ends should be at lease 150 mm (6"). Laps and final edges should be liberally treated on their undersides with FELT ADHESIVE and well compacted. Timber Roofs: On timber roof structures, the first layer of felt must be nailed down to comply with BS CP 144: Part 3: 1970, the second and third layers may be bonded with FELT ADHESIVE.
