Amount

M&L for surface preparation - Concrete floor should be clean, sound and free from contamination such as oil and grease, mortar and paint splashes or curing compound residues and previously done resin flooring, etc. These deposits are best removed by mechanical grinding/scarification or light shot blasting followed by thorough cleaning using vacuum cleaners. Removal of all oil, grease, etc can also be done using a degreasing solution and brushing the floor with hard broom or wire brush and then detergent washing and mopping. If wetting of the floor has taken place during preparation, it must be allowed to dry out (surface moisture content should be less than 5%) before commencement of EPU floor application. All cracks and construction joints need to be cut open. Cracks need to be cut open in a 5mm x 5mm groove and construction joints at full width up to 1/3 rd depth of the concrete thickness or till the loose concrete and to be filled with rigid epoxy putty (as per manufactures specifications), complete all as specified and directed.

Supplying and applying 5 mm thick heavy duty, chemical resistant, abrasion resistant Epoxy Polyurethane Flooring system over old concrete surface (3 mm thick epoxy primer/ scratch coat and screed + 2 mm thick self leveling/ smoothing top coat) - (i) Immediately prior to priming, the surface (application area) should be thoroughly cleaned to remove any remaining traces of dust or other loose materials using suitable means. Providing and applying solvent free epoxy primer at a coverage rate (Base : Hardener proportion as per manufactures specification) in two coats using a brush or short/ medium pile roller at a time gap of 8 hrs, ensuring a uniform coating is achieved, allowing second coat to dry for 24 hrs or as per manufacturers instructions, care should be taken to avoid over application. (ii) Providing and applying a epoxy screed (Base : Hardener : Aggregate) at a coverage rate (as specified by the manufacturer) of up to a nominal 3 mm thick (including thickness of epoxy primer) over prepared (old) concrete floor (application area) using a notched trowel or a pin screed. Immediately roll the spread material with spiked roller to release all entrapped air and remove trowel marks. The rolling should be carried out using a back and forth technique along the same path. An overlap of 50% with adjacent path is recommended. The screed should be allowed to cure for 12-48 hours at 20 o C before applying top coat. (iii) Providing and applying a self leveling/ smoothing top coat of EPU resin (Base : Hardener : Aggregate : Color pack) at a coverage rate (as specified by the manufacturer) of up to a nominal thickness 2mm over previously cured surface of epoxy screed using notch trowel or pin screed and using the approved color shade. Immediately roll the spread material with spiked roller to release all entrapped air and remove trowel marks. The rolling should be carried out using a back and forth technique along the same path. An overlap of 50% with adjacent path is recommended. The finished surface should be protected from other trades using kraft paper or similar breathable material. Polythene should not be used. Protect the installed floor from damp, condensation and water for at least 4 days, complete all as specified and directed.

Note for Ser Item No 1 & 2 :- (i) Anchorage groove cutting by mechanical cutter machine with double size of proposed PU floor thickness to all end points of flooring, offsets and as per the instruction of manufacturer should be provided without any extra cost before application of primer/ scratch coat.
