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.



Surface preparation

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.
