New surfaces: Surface must be thoroughly cleaned, free of dust & grease and washed well with water. Treat any areas affected by algae, moss or fungal growth with Polycolor Fungicidal Wash & Treatment. If cracks of up to 3mm is present, it shall be treated with Polycolor Waterproofing Crack Filler.
Surface Preparation for Old/Repainted Substrate

Existing substrates must be cleaned to remove all dirt, mildew and other contaminants. Treat any areas affected by algae, moss or fungal growth with Polycolor Fungicidal Wash & Treatment. This is accomplished by pressure-cleaning equipment with a minimum capability of 100-140 bar water pressure. All grease, oils and asphalt materials must be removed completely. Also, remove any other old film on the surface.

Sealing: After the proper surface preparation and curing of repaired areas, wash the surface well and maintain it. In dry surface condition, proceed with priming by using Polycolor Durabond A; dilute with water in 1:3 ratio (1-part Polycolor Durabond A diluted with 3 parts water). Maintain the spreading for a single coat application to achieve about 20 – 25 microns DFT. Allow it to dry for 4 hrs.

Priming: Apply 1st coat Polycolor Acrylic Waterproofing with a dilution up to 30% and let dry for 4 hours.

Membrane: Bed the Polytol membrane into the wet coat by using a roller avoiding bubbles and wrinkles formation.

Coating:
1. Apply 2nd coat Polycolor Acrylic Waterproofing without dilution.
2. Apply 3rd coat of Polycolor Acrylic Waterproofing without any dilution.
