KAMICRYL ELASTOFALT

HIGH PERFORMANCE Aliphatic Polyurethane MODIFIED LIQUID WATERPROOFING MEMBRANE

KAMICRYL ELASTOFALT is a high performance, ready to use, cold applied, single component, elastomeric high build liquid waterproofing membrane, based on Aliphatic Polyurethane modified bitumen emulsion. KAMICRYL ELASTOFALT 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. KAMICRYL ELASTOFALT is highly resistant to chlorides and sulphates commonly present in the soil. It is also highly UV resistant.

Uses

• Better film thickness - Provides 1mm dry film thickness in 3 coats as compared to 300-400 microns in 2 coats of other products.

• High Crack bridging ability - Bridges cracks upto 2 mm width as compared to 0.5 mm by other products

• No need to remove existing sound BB coba, Plaster, concrete surface

• Can be used for flat as well as sloping roofs

• High tensile strength, tear resistance & bond strength - With cementitious substrates as compared to available products

• Good resistance - Against UV, Infrared rays and algal & fungal growth Light in weight

• Easy in application - Can be applied by roller.

• Non toxic, breathable & washable

• Aesthetic finish – Available on request in White, Dark Grey & Light Grey colours for different coats

• Existing cementitious waterproofing treatments like brick-bat-coba, concrete screeds, acrylic coatings, etc.

Existing cementitious waterproofing treatments like brick-bat-coba, concrete screeds, acrylic coatings, etc.

Method of Application

Surface Preparation

• Prepare the surface thoroughly by cleaning, washing and removing dust, dirt, oil, grease and loose particles.

• Ensure that the roof slope is a minimum of 1 in 100.

• In existing old terraces such as brick-bat-coba or screeds, the substrate must be checked for its soundness. Damaged or hollow portions, sharp edges etc. must be cut and repaired with a polymer-modified screed. Surface cracks must be filled with polymer-modified mortar in case of wider cracks.

Application Procedure

• Apply one coat of SEALCOAT PRIMER (SEACOAT diluted with water in the ratio 1:1) at the rate of 12-15 sqm per litre. Allow it to dry for 2-3 hours

• Apply the first coat of SEALCOAT at the rate of 4 sq.m. per litre and allow it to dry before taking up the second and third coats, the rate of application being the same.

• The sequence of colours viz. White, Dark Grey and Light Grey can be decided depending on the desired top coat colour.

• In case only two colours are being used, ensure that the colour of the first and the third coat are the same. This would ensure correct consumption of material that will deliver a total DFT of 1 mm.

• Drying time between coats will be 6 - 8 hours

• Ensure that the primer and the 3 coats of SEALCOAT totally achieve a minimum thickness of 1 mm DFT

Allow the system to air cure for 7 days.
