Directions for Use

Surface Preparation

  • Concrete shall be a minimum of 21 days old and/or the residual moisture content shall be below 6%.
  • The concrete shall then be prepared by grit blasting, mechanical scabbling, or similar, to produce a clean, exposed aggregate finish, free from dust, dirt, oil, grease, laitance and other contaminants.
  • Old concrete shall be mechanically prepared to remove all contaminants.
  • Defective concrete shall be removed, cutting back to sound substrate and patch repairs may be carried out as required.

Mixing

  • The use of mechanical, forced action mixer such as a Creteangle, is strongly recommended.
  • Pour the contents of the CURING AGENT container into the BASE container and mix thoroughly.
  • The mixed resins shall be poured into a mixing vessel, (Creteangle bucket or similar), and the AGGREGATE added steadily whilst the mixer is in motion.
  • Mix for 2-3 minutes until a uniform consistency is achieved.

Priming

  • Apply a coat of CPR 410 – Acid Resistant Epoxy Concrete Primer to the prepared surface at a a rate of 3.3 to 5.0 m²/kg (depending upon surface texture).
  • Within 90 minutes of the primer application, CPR 604 Acid Resistant Screed – Epoxy HB shall be applied.

Application

  • Lay the material, utilising screeding bars or screed box, ensuring good compaction, and finish with a stainless steel or chemically resistant plastic float.

Sealing

  • For chemical resistant applications it is necessary to seal CPR 604 Acid Resistant Epoxy Screed with a minimum of two coats of CPR 602 Acid Resistant Epoxy Paint . Please refer to the CPR 602 Acid Resistant Epoxy Paint data sheet for application details.
