bitu.seal liquid

Any surface to which bitu.seal liquid is applied must be clean, sound and dry. Steel – must be free of grease, oil, rust and scale. For best results steel should be abrasive blast cleaned to a minimum standard of SA 2 on the Swedish Code of Practice SIS 055900.

If hand cleaned, a standard of SA 3 should be aimed at. Galvanised steel – must be completely free of grease and of anti-white rust compounds, which should be removed by scrubbing with a mixture of abe^® super brush cleaner and abrasive soap. All residues must be washed off with clean water.

Concrete and other cementitious surfaces – must be free of dust and laitance.

Timber – must be clean and fairly smooth.

Weathered roofing membrane – remove all dust and chalky surface products.

Prime with a coat of bitu.prime, which should be allowed to dry prior to overcoating, except for steel which must be coated with a suitable anti- corrosive primer like 4 metal primer.

bitu.seal liquid must be stirred well to disperse fillers, and intermittent stirring during use is advisable. Always use a flat paddle.

bitu.seal liquid may be applied by stiff brush, such as a worn paint brush.

bitu.seal liquid can be used in conjunction with a glass fibre membrane to build and reinforce thicker coats. The membrane must be set into the still wet film of bitu.seal liquid and ideally all bubbles and wrinkles should be removed by means of a laminating roller.

The film is allowed to dry and then a second coat is applied at a sufficient thickness to completely obliterate the weave and pattern of the membrane.

Tools, brushes and mixing equipment should be cleaned immediately after use and before material has set with abe^® super brush cleaner followed by washing with soap and water.

Where the bitu.seal liquid film is finally to be exposed to the effects of sunlight and ultra-violet radiation, it is recommended that, some 3 – 4 weeks after being applied, it be overcoated with silva.^®kote.

bitu.seal liquid is also an excellent reviver coat for roofing membranes that are showing signs of breakdown of their binder. The cleaned surface should be treated with bitu.prime and a final coat of silva.^®kote should be applied over the bitu.seal liquid film.

Application temperature range: 5°C to 40°C

Do NOT apply if humidity is in excess of 85%.

Do NOT apply if surface is less than 2°C.

Heavy duty bituminous coating for bridge abutments, foundations, retaining walls and similar installations.

The coating will be bitu.seal liquid, a solvent-borne, fibre-filled, bituminous solution applied in accordance with the recommendations of a.b.e.^® Construction Chemicals, including bitu.prime or 4 metal primer where necessary. The solution will have a minimum solids content of 46%.
