706 MMA Floor Primer is a rapid curing, general purpose primer enabling fast overcoating. The product exhibits outstanding adhesion to concrete, as well as steel, masonry, and marine plywood, and the fast curing characteristics allow rapid application of subsequent coatings, mortars or screeds.

706 MMA Floor Primer has been developed as a general purpose primer, being used prior to any of our MMA range of coatings, mortars, and screeds.

706 MMA Floor Primer is supplied as a two pack material, comprising pre-weighed amounts of Base and Catalyst components. The mix ratio is fairly tolerant to variations within the range of 1% to 5% addition of Catalyst, so that part packs may be used if care is exercised.

This product is for Professional Use Only.

Coverage

• A 5kg pack is sufficient to prime an area of 15-20m²
• Exceptionally porous surfaces may require a second coat

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, and existing paint finishes, etc
• Suitable mechanical treatment such as vacuum grit blasting or mechanical scabbling is recommended to ensure the removal of contaminants and to provide a mechanical ‘key’ for the primer

Mixing:

• Pour the contents of the catalyst container into the base container and thoroughly mix, preferably by mechanical means

Mixing Ratio:

• (% Catalyst by Weight) = 2.4

Application

• Apply by squeegee to distribute evenly over the floor, and then use a long nap lambswool roller to achieve a nominal application rate of 0.25-0.30kg/m²
• Allow to cure for a minimum of 40 minutes prior to applying any other MMA products from our range
• If an interval of more than 8 hours between primer application and subsequent overcoating is anticipated then the primer shall be scattered with fine silica sand before hardening

Cleaning

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

Curing

• Minimum overcoating interval: 40 minutes @ 20°C

Limitations

• Do not apply to wet, uncured concrete surfaces

706 MMA Floor Primer will taint food during application, so that all foodstuffs in the immediate vicinity must be removed or properly covered
