TDS For Polypoxy CR
- Step by Step
Surface Preparation
New concrete surface to be treated must be 28 days old. Ensure that the moisture content of the surface is less than 5%. The surface shall be free from dust, dirt, curing compound and laitance. The cleaning shall be done by grit/captive blasting or mechanical grinding. The concrete should be sound and any cracks, pot holes shall be repaired with Polypoxy BF* or Polypoxy NF*. Prior to the application of the coating make sure that the surface is absolutely dry.
Priming
The coating can be directly applied on new concrete surface, provided the surface preparation is done thoroughly to ensure good adhesion. For old and porous concrete, prime the prepared surface with Polyprime EP@ 4-5m2/l. The coating is applied when the primer is dry. However, in all circumstances, the coating shall be applied within 24 hours of application of the primer. If the primer surface is left open for more than 24 hours, then a fresh coat of primer has to be re-applied.
Mixing
Mix part A (resin) and part B (hardener) separately for 1 minute using a slow speed drill fitted with a paddle. Then add Part B into Part A and mix thoroughly for 2 – 3 minutes to achieve uniform consistency. Apply immediately after mixing.
Application
Polypoxy CR may be applied by brush, squeegee, roller or industrial sprayer. The coating shall be applied @0.3 l./m2 to achieve a Dry Film Thickness of 300 microns. on horizontal surfaces the coating can be applied in a single coat of 300 microns. As the coating is heavy bodied, on vertical surfaces it shall be applied in 2 coats of 200 microns in each coat to avoid sagging/slumping. Each subsequent coat shall be applied only after the previous coat dries off completely. After application the coating must be back rolled to reduce surface irregularities and improve bonding.
