How to use

SURFACE PREPARATION & PRIMING

All the surfaces must be cleaned and made free of dust,
dirt, moss, oil, grease and other loose particles. This can
be achieved by grit/sand/shot blasting. As a minimum,
vigorous wire brushing should be employed. All pin holes and surface defects shall be repaired with a suitable
Polycrete* concrete repair mortar.
Polythane P does not require priming and can directly
be applied onto the concrete surface. In case of highly
porous surface, a priming coat is recommended to seal
the pores and stabilize the surface. The primer coat can
be produced on site by diluting Polythane P 1 to 1 with
water. Apply the primer coat @ 5m²/L and allow to dry.

MIXING & APPLICATION

Polythane P is a single component product but mix the
contents of the pail thoroughly prior to application to
remove any sediment. A slow speed drill and suitable
paddle mixer shall be used to avoid the formation of air
bubbles.
The coating can be applied with a brush, roller or airless
spray and shall be applied in a minimum of 2 coats. The
1st coat shall be allowed to dry completely before the 2nd
coat is applied. The 2nd coat shall be applied cross wise
to the first coat. The coating will achieve its full strength
after a curing period of 7 days. 

CORNER DETAILING

It is recommended to reinforced all corners with
Watertite CL 252 sealing strip. The sealing strip shall
be embedded into the first coat whilst it is still wet and
covered fully with the second coat.
