Polymer treatment for roofs
Cleaning and drying the surface; applying two coats (DFT of 200-300 micron) of a translucent brown coloured phenolic resin based single component high performance polymeric waterproofing compound (sp. gr. 0.87, rosin content nil and a solid content of minimum 0.47%), e.g., PERMAPROOF @ 0.6 litre per square metre, with demonstrable properties of resistance to water and acid; spraying a layer of dry coarse sand on the second coat when it will still be wet; removing excess sand on the following day; permitting the coatings to cure and dry naturally for 3-7 days
Requirement : 0.60 litre/sqm for roofs and similarly exposed surfaces above ground, other than water retaining structures
