EXTRACOAT RUBBER is a bituminous elastomeric water soluble emulsion which is brown in colour. It consists of bitumen, resins and special additives.
The film of EXTRACOAT RUBBER which is formed after the evaporation of water has an excellent elasticity and exhibits good resistance to diluted acids , alkalis solutions and to various corrosive chemicals.
It does not resist to oils.
EXTRACOAT RUBBER is an excellent waterproofing material which can be applied on foundations, basements, walls, roofs (flat or inclined). Also it is used as an adhesive of thermal insulation materials It can also be used as a water vapour barrier.
Diluted with water can be used for fixing bituminous membranes.
EXTRACOAT RUBBER can be applied to many substrates such as concrete ,stone, metal or wood. It is compatible with polyurethane and polystyrene.
INSTRUCTIONS FOR USE
The surface must be smooth ,clean and dry ,free from dust,oils ,grease and other debris.
EXTRACOAT RUBBER is cold applied by brush, roller or spray gun.
For the application of bituminous waterproofing membrane it is advisable to dilute the product up to 30 % with water in one layer. The installation of the membrane to the primed substrate can start in a crisscross way only after the evaporation of the water (at least 24 h) and the dry film formation.
For the waterproofing of surfaces the application of at least two coats is recommended provided that the previous layer is completely dry.
The application of one thick layer of EXTRACOAT. RUBBER must be avoided.
The use of a reinforcement between two coatings of EXTRACOAT RUBBER increases the mechanical strength of the system.
When the surface waterproofed with EXTRACOAT RUBBER is exposed to direct sun radiation it must be protected with bituminous aluminium paint ALUCOAT to prolong its life span and avoid premature ageing.
It is used at a consumption of 0.5- 1.0 kg/m² depending on the porosity and smoothness of the surface.
When the material is still wet cleaning can be made with water.If it has dried gasoline, oil or other proper solvent can be used.
Extended contact with skin is to be avoided .For more information, please consult the Material Safety Data Sheet.
EXTRACOAT RUBBER should be kept in firmly closed cans at a temperature higher than 0°C. The properties of the EXTRACOAT RUBBER remain unchangeable for at least one year under normal storage conditions.
The product is supplied in cans of 5kg, 19kg and in barrels of 220 kg.
