CPR 727 – Epoxy Grout

Description

Epoxy Grout

CPR 727 – Epoxy Grout is a three pack, pourable, resin based grout with high mechanical strength. It consists of a combination of formulated resin and specially graded fillers which produce a high
performance, free-flowing resin grout for gap widths between 5 – 40mm.

Typical Properties

• High Strength
• Very good flow properties
• Excellent mechanical properties
• Very good chemical & weather resistance
• Minimum creep
• No primer required, excellent adhesion
• Pre-weighed components for ease of use

Direction 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

• CPR 727 – Epoxy Grout is supplied as a 3 pack material: BASE component, CURING AGENT component and the FILLER component.
• Mix the BASE and CURING AGENT components under mechanical stirring, and gradually blend the FILLER into the mixed resin components for 1-2 minutes.

Application

• Pour the mixed grout from one side, ensuring a sufficient hydrostatic, ‘head of grout’ is created to achieve the desired flow.
• Where multiple mixes are required to fill the void ensure that no delay occurs between mixes.
• Do not vibrate the material.

Curing

• CPR 727 – Epoxy Grout will be hard dry following 4 – 6 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.

Equipment Cleaning

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

Limitations

• Do not apply to wet or uncured concrete surfaces.
• Do not apply at temperatures of 5°C or less.

Coverage

• A 26Kg pack will yield 12.5 Litres of mixed grout
