EXTRACOAT is a bituminous water soluble emulsion dark brown in colour, pulp in form. It consists of bitumen, water and special additives. The film that is formed after the application and drying out of EXTRACOAT is not affected by thin acids and alakalis solutions and various corrosive chemicals.
It does not resist to oils.
EXTRACOAT can be applied to many substrates such as concrete ,stone or wood.
It is compatible with polyurethane and polystyrene.
EXTRACOAT is an excellent waterproofing material which can be applied on foundation basements, walls, roofs (flat or inclined). Also it is used as an adhesive for thermal insulation materials. It can also be used as a water vapour barrier.
Diluted with water it can be used for bonding bituminous membranes.
INSTRUCTIONS FOR USE
The surface must be smooth ,clean and dry ,free from dust,oils , grease and other debris.
EXTRACOAT is cold applied by brush, roller or spray gun.
For the application of bituminous waterproofing membrane only one layer of EXTRACOAT is sufficient. The recommended dilution is up to 30% with water The installation of the membrane to the primed substrate can start 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 first layer is completely dry.
The application of one thick layer of EXTRACOAT must be avoided
The use of a reinforcement between two coatings of EXTRACOAT increases the mechanical strength of the system.
When EXTRACOAT is used for the waterproofing of surfaces exposed to direct sun radiation, it must be protected with bituminous aluminium paint ALUCOAT to extend its life span and avoid premature ageing.
It is used at a consumption of 0.5- 1 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 should be kept in firmly closed cans at a temperature higher than 0°C .The properties of the EXTRACOAT remain unchangeable for at least one year under normal storage conditions.
The product is supplied in cans of 5kg, 19 kg and in barrels of 220 kg.
