Coverage

• 2.0 - 3.3m²/Kg depending on surface texture

Surface Preparation

• New concrete surfaces shall be a minimum of 7 days old
• Old oil-contaminated concrete surfaces shall be washed with detergent and water and allowed to dry
• Suitable mechanical treatment such as vacuum grit blasting or mechanical scabbling are recommended to ensure the removal of contaminants

Mixing:

• 403 Oil Tolerant Primer is supplied in pre-weighed containers ready for mixing
• Pour the contents of the curing agent tin into the base container and thoroughly mix, preferably by mechanical means until a uniform colour is achieved

Mixing Ratio:

• By Volume - 1.94 Base : 1 Curing Agent
• By Weight = 100 Base : 48.8 Curing Agent

Application

• Apply by brush, roller or squeegee to the prepared surface at a nominal rate of 0.3 to 0.5Kg/m²
• Ensure that the surface is thoroughly wetted out
• If the primer is to be allowed to cure prior to overcoating, then it is permissible to broadcast 0.4-0.7mm 504 Standard Anti-Slip Aggregate into the wet primer to assist subsequent adhesion of our Epoxy Coatings
• Our Epoxy Screeds and Mortars may be applied to the wet primer

Cleaning

• Clean equipment with 109 Tool Cleaner prior to curing of the coating

Curing

• Touch dry after 8 hours @ 20°C
• Hard dry after 16 hours @ 20°C

Limitations

• Do not apply to temperatures below 3°C, or if there is a risk of frost during the initial curing period
• With severely contaminated old concrete it is recommended that a pull off adhesion test be carried out prior to full scale application
