DIRECTIONS FOR USE

Perma Bitu Coat Primer
Mix one volume of Perma Bitu Coat with four Volumes of water. One litre Perma Bitu Coat can prime 450 Sqft of area.

Perma Bitu Coat Putty
Mix one volume of Perma Bitu Coat with two volumes of quartz powder or silica flour.

Perma Bitu Coat Mortar
Mix one volume of Perma Bitu Coat with three volumes of dry natural sand. One litre Perma Bitu Coat yields two litres of mortar.

1. Waterproofing normal concrete and brick bat coba:
   Clean the surface to remove all loose particles. Cracks if any on the surface can be suitably widened. Prime the widened cracks and fill them with Perma Bitu Coat Putty. If there are depressions and pot holes then prime the depressions with one coat of Perma Bitu Coat and fill and level the depressions and pot holes with Perma Bitu Coat Mortar. Brush apply Perma Bitu Coat on entire surface in two or three coats. Provide fibre glass of scrim fabric at junctions of vertical and horizontal surfaces.
2. Repairing damaged bituminous felts:
   Cut to widen the cracks and cut out the de-bonded felt. Prime and fill the cracks with Perma Bitu Coat Putty and fill the de-bonded cut out areas with Perma Bitu Coat Mortar. Brush apply Perma Bitu Coat on the entire area in two coats.
3. Asbestos /Zinc /Aluminium Sheet roofing:
   Provide scrim or fibre glass fabric at J. Bolts and junction of sheet over one coat of Perma Bitu Coat and then brush apply Perma Bitu Coat on the entire surface in two to three coats.
4. Cracked drainage pipes:
   Brush apply Perma Bitu Coat on the cracked pipe. When the first coat is still wet wrap glass / scrim fabric around the pipe and apply second coat of Perma Bitu Coat on the fabric.
5. Damp proof course:
   On the cleaned plinth apply two coats of Perma Bitu Coat. The second coat applied after about four hours of first coat. When the second coat is still wet blind it with clean sharp sand to provide mechanical key.
6. Concealed water and drainage pipes:
   It is a good idea to coat all concealed water and drainage pipes with Perma Bitu Coat to protect concrete from damage due to leakages. Apply one coat of Perma Bitu Coat on the pipe and wrap it with fibre mesh and apply second coat of Perma Bitu Coat and back fill.
7. Subsoil Structures:
   Subsoil structures though main load bearing, in majority of the cases are subjected to water pressure along with termite chloride and sulphate attack. Hence before back filling all subsoil structures such as basement walls, footings etc should be coated with two coats of Perma Bitu Coat before back filling.
8. Anti-termite treatment:
   Coating of Perma Bitu Coat applied on to the footings and columns up to ground level serves as highly effective anti-termite treatment. Most often when conventional anti-termite treatments fail, Perma Bitu Coat gives permanent anti termite protection. Two coats of Perma Bitu Coat applied over Perma Bitu Coat primer serves as very effective anti-termite treatment.
