M&L in repair for preparation of existing concrete surfaces and applying 5 mm thick epoxy polyurethane system including cleaning of surface from dust, dirt, moisture & all foreign materials from the floor. All floors to be cleared by means of scrubber, Acid itching shall be done to the floor followed by alkaline wash & then the surface shall be cleaned by potable water . After that the floor shall be cleaned by using solvent/degrease cleaner to remove residues for floor cleaning all mechanized equipment shall be used like scrubber, sanders, hot blowers, vaccum cleaners, moisture test machine complete all as specified. Note:- Screed, Primer and top coat shall be measured and paid seperately under respective items of BOQ.

M&L for epoxy based self leveling screed having a minimum thickness of 3800 microns. The self leveling screed shall consist of a low viscous epoxy-amine cured system and graded aggregates. The epoxy system shall have a volumetric ratio of mixing of resin in (2:1) ratio. The aggregates shall be added in the ratio of (1:3) or (1:3:5). The screed shall have compressive strength of minimum 70 N/Sqmm. The layer shall be desecrated by spike roller to dislodge air pockets.

M&L for applying primer of two component, solvent-free, epoxy-polymido amine system having a volumetric ratio of mixing of 2:1. Mixing resin and hardener by weight shall not be allowed. The primer shall be applied @ coverage of 5 Sqm per litre, yielding a DFT of 200 microns complete all as specified and as directed.

M&L in repair for applying EPU based self levelling top coat. The top coat shall be of EPU type where urethane linkages are infused in to epoxy matrix, so as to enhance wear resistance, flexibility and impact resistance. EPU top coat shall have a columetric ratio of mixing of (2:1). No filler or aggregates are added in the topcoat at the site, as the addition of fillers will reduce the flexibility. It should yield a thickness of 1000 microns. The volumetric mixing ratio will be (2:1). The compressive strength of the top coat shall be in the range of 60-70 MPa, Tensile strength will be 15-20 MPa, Elongation in the range of 45-50% and flexural strength in the range of 40-50 MPa. Top coat wear resistance (weight loss)/ Abraission Resistance<37 mg.
