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.
