How to use

APPLICATION CONDITIONS & SURFACE PREPARATION

The application temperature should be between 5°C to
45°C. Application procedures may vary slightly depending
upon site conditions.
The surface shall be cleaned thoroughly of all contaminants
like dust, traces of curing compound, oil and grease. Light
mechanical grinding/grit blasting/high pressure water jet
may be used to clean the surface of all the contaminants
depending on the degree of contamination on the surface
to be coated. All surface imperfections and protrusions
shall be removed and repaired. Structurally unsound and
friable concrete must be removed and repaired with a
suitable Polycrete* concrete repair mortar.

PRIMING

A primer coat is recommended, particularly on the vertical
surfaces to seal the pores and stabilize the surface. The
primer coat can be made in the site by diluting the Polycryl
FR 1 to 1 with water. The primer should be applied at a
coverage rate of 4-5m2/L. On horizontal surfaces Polycryl
FR can be applied directly without primer provided that
recommended surface preparation has been carried out. 

MIXING & APPLICATION

Polycryl FR is single component but stirring of the pail is
recommended prior to the application of the coating. This
will remove any sediment which may occur during storage.
The use of a slow speed drill and suitable paddle should be
used in order to avoid the formation of air bubbles.
Apply the coating with a brush, roller or airless spray.
Allow the coating to dry completely before applying the subsequent coats. 2 coats should always be applied; the
second coat at 90° to the first. We recommend that a nonwoven geo-textile membrane be embedded into the first
coat whilst it is still wet at all expansion joints projections
and corner fillets to reinforce these areas. Allow the final
coating to cure fully (72 hours) after which it can be put
in service. For roof applications, the coating should be
applied @1.1 L/m2/coat for a DFT of 1.5mm in 2 coats.
As a protective coating, vapor barrier on concrete/render/
plaster surfaces, the coating should be applied @0.70 L/
m2/coat for a DFT of 1mm in 2 coats.
