Directions for Use

Surface Preparation

Concrete substrates shall be sound, clean and free from dust, dirt, grease, oils, laitance and other contaminants.
A roughened or profiled surface will ensure optimum adhesion.
Mild steel and other metallic substrates shall be degreased, power wire brushed or grit blasted and vacuumed free from dust.
Other substrates shall be sound, clean and free from dust, dirt, grease, oil and any oxidised surface layer.

Mixing

The Base and Curing Agent components shall be thoroughly mixed together using a stiff spatula or a slow speed drill with paddle attachment until a uniform grey mixture has been produced.

Application

The application of CPR 702 – Epoxy Bonding Adhesive is best achieved using a spatula, trowel, serrated trowel or stiff bristled brush depending on the area to be treated.

Bonding Surfaces Together

CPR 702 – Epoxy Bonding Adhesive shall be applied to each of the two surfaces to be bonded.
The surfaces are then pushed together to achieve the required bond thickness.
Excess adhesive should be removed and the joint protected from movement until the resin has set.

Patch Repairs

Scrape or ‘knife in’ the CPR 702 – Epoxy Bonding Adhesive and finish with trowel, palette knife or spatula.
Note: For more inaccessible areas, CPR 702 – Epoxy Bonding Adhesive may be placed into empty cartridges and injected/‘gunned’ into place using a standard sealant gun.

Equipment Cleaning

Clean equipment with CPR 201 Tool Clean Solvent prior to curing of the coating.

Curing

CPR 702 – Epoxy Bonding Adhesive will be hard dry following 10-12 hours cure @ 20°C.
At higher temperatures this period will be reduced and at lower temperatures this period will be increased.
Allow 7 days for optimum mechanical properties and full chemical resistance.

Storage and Shelf Life

Store in dry conditions at temperatures between 10°C and 25°C.
Protect from frost.
CPR 702 – Epoxy Bonding Adhesive has a minimum shelf life of 12 months when stored in original, unopened containers in accordance with manufacturer’s instructions.

Packaging

CPR 702 – Epoxy Bonding Adhesive is supplied in 1kg, 2kg and 5kg packs
