KAMICRYL-LAVATEX
HIGH PERFORMANCE RUBBER MODIFIED LIQUID WATERPROOFING  MEMBRANE

LAVATEX is a high performance ready to use, cold applied, high build liquid waterproofing membrane based on polymer modified bitumen emulsion. LAVATEX forms a seamless, highly elastic and durable film that adheres well to most of the common substrates e.g. concrete, cement blocks, wood, existing roof felts. LAVATEX is highly resistant to chlorides and sulphates commonly present in the soil.
 
Uses
·  Waterproofing of concrete and block foundations, retaining walls, basements and wet areas 
   such as kitchen, toilet floors and balconies.
·  Damp proof membrane in sandwich panel constructions
·  Curing membrane cum protective coating for sub structure
·  Facade damp proofing
 
Features
o Single component, ready to use
o Creep resistant to temperatures up to 120 0C 
o Easy to use
o Non-flammable and Non-toxic
o Applicable immediately after removal of the formwork
o Resistant to chlorides and sulphates commonly present in the soil.
o Environment friendly
Typical product characteristics
Appearance :

Thixotropic black emulsion dries to a black  Flexible protective membrane.
Specific Gravity : 1.04   +/- 0.01
Non-volatile content : 65% Min
Rubber content : 10% Minimum
pH : 10.0 – 12.0
Drying Time : 1 – 3 hours
Full dry : 3 –4 days
The drying time depends on the type of substrate, temperature,humidity and thickness of layer, etc.
Properties of dry film :
Softening point R & B (ASTM D36 - 84) : >120°C
Water vapour permeability (ASTM E96 - 92) : >0.15gr/m2/day
Elongation at break (ASTM D412) : >900%
Recovery at 350% elongation (ASTM D412) : >50%
Resistance to water (ASTM D2939) : No Blistering or re-emulsification
Protection of buildings against Ground water : As per BS 102 Code of practice.
Curing membrane : ASTM C 309:1998
Surface Preparation
All surfaces should be sound, clean and free of contaminants. Absorbent surfaces e.g. concrete should preferably be dampened with water.  In kitchens, toilets and other wet areas all the openings should be properly sealed.  On all weak points such as cracks or around the pipes use a woven fibreglass mesh as reinforcement between the two coats of LAVATEX.
Application
LAVATEX can be applied by brush, roller or squeegee. Hot, dry or very porous substrate should be dampened with clean water prior to application of LAVATEX.  When two or more coats are required, ensure that the preceding coat is fully dry before applying the successive coat, which should be applied at right angle to proceeding coat.  LAVATEX also acts as a non-degradable curing membrane; hence it may be applied immediately after the removal of mould, to the concrete structure, which has no aesthetic value such as the sub structure of the building.
Application Rate
* For damp proofing/vapour barrier Apply two coats @ 250-300 grams/m2/coat
* Waterproofing membrane Apply two coats @ (approx.) 1.0 kg/m2/coat
* Curing membrane     Apply two coats @ 0.4 kg/m2/coat
