Step by step

SURFACE PREPARATION

Concrete surfaces:

The concrete surface to be coated must be clean, dry and free of laitance, oil, grease or any substance that may impair adhesion. Methods of substrate preparation includes, grit blasting, highpressure water jet cleaning, surface grinding etc. Weak or damaged concrete must be removed and repaired properly with Polypoxy NF.

PRIMING

Prime the surface with Polyprime eP (Solvent free 100% solid epoxy primer @ 4-5 m2/kg) depending on the substrate condition.

Metal surfaces:

Surface should be sand blasted or should be manually or mechanically sanded get a rust free finish. if necessary prime the surface with Polyprime ePS.

Fully cured epoxy surface Clean the surface thoroughly, remove dust or any oil which is left on the surface and directly apply Polyguard PU. noTe:-Primers should be completely dry before applying Polyguard PU.

MIXING

Mix both parts of Polyguard PU thoroughly for a few minutes to remove any sediment. Then add the contents of Part B to Part A and mix with a suitable paddle mixer fitted to a slow speed electric drill. The mixing is to be continued till a uniform and homogenous consistency is achieved.

APPLICATION

The material can be applied with a brush, roller. Apply the mixed material @ 120–150 micron WFT. if required a second coat can be applied at right angles to the first coat at the same coverage rate. For getting an anti skid finish, broadcast Aggregate no. 8 @ 0.5-1.2 kg/m² on the wet primer. leave it for 24 hours and then when the primer has fully set, brush/vacuum away the excess aggregate from the surface. Apply the top coat as specified.
