Wash the surface with Dulux Aquatech Pre-Treatment coat and fill the cracks with Dulux Aquatech Crackfiller (in case of cracks larger than 20mm repair the roof with plaster) and ensure slope is maintained.

Apply the first coat of undiluted Aquatech Roof using brush or roller on roof and parapet surface. Allow the surface to dry for 5-6 hours. Apply the second coat of Dulux Aquatech Roof Waterproof at 90 degree angle to the first coat application. During application ensure that the forced coverage of 8-10sqft per liter is maintained to reach at the desired dry film thickness.
Step 3 : Drying time
Touch Dry for the basecoat is up to 2 hours and allow 5-6 hours for complete drying.
