Directions for Use

Surface Preparation

Concrete surfaces shall be a minimum of 21 days old and/or the residual moisture content shall be below 6%.
Ensure that the concrete is clean and free from dust, laitance, grease, oil, curing compound, existing paint finishes, etc.
Suitable mechanical treatment such as vacuum grit blasting or mechanical scabbling are recommended to ensure the removal of contaminants and to provide a mechanical “key” for the CPR 413 – Acid Resistant Concrete Primer.
Steel reinforcement shall be abraded, wire-brushed etc. to remove all traces of rust. Priming should immediately follow preparation to obviate the possibility of flash rusting.

Mixing

Pour the contents of the CURING AGENT container into the BASE container and thoroughly mix, preferably by mechanical means until a uniform colour is achieved.

Application

Apply by brush, roller or airless spray at a nominal rate of 0.15 to 0.30kg/m².
Ensure that the surface is thoroughly wetted out.
Allow the primer to “tack up” for a minimum of 10 minutes prior to the application of CPR 605 – Self Sealing Acid Resistant Screed or Acid Resistant Epoxy Screed.
In thin section the primer will remain “open” for 90 minutes @ 20°C, within which time subsequent application should be carried out.
Should this period be exceeded then the surface must be re-primed prior to continuing.
As a sealer for Bund Coat 3 if required, the CPR 413 – Acid Resistant Concrete Primer may be applied following 6 hours cure of the coating @ 20°C.

Equipment Cleaning

Clean equipment with CPR 201 – Tool Clean Solvent immediately after use.

Curing

Touch dry after 3 hours @ 20°C.
Hard dry after 6 hours @ 20°C.

Storage and Shelf Life

Store in dry conditions, out of direct sunlight, at temperatures between 10°C and 25°C.
CPR 413 – Acid Resistant Concrete Primer has a minimum shelf life of 12 months when stored in original, unopened containers in accordance with manufacturer’s instructions.
