Resist Epoxy

Resist Epoxy is 100% solids, solvent-free, two-component epoxy system. Formulated to seal, protect and lengthen the life of concrete and parking structures, RESIST SAND FINISH OVERLAY also provides exceptional skid resistance with a top layer of specially selected aggregate.

RESIST EPOXY FEATURES

• Excellent bond strength for a durable, yet flexible coating that is insensitive to moisture.
• Superior resiliency and impact resistance.
• Bonds directly with the surface for exceptional chemical resistance and waterproofing.
• Non-shrink and flexible enough to withstand slight movement and extreme temperature changes.
• Provides skid resistance with a top layer of specially selected aggregate.
• Economical and long-lasting.
• Easy to use 1:1 mixing ratio.

USES

Suitable for exterior use on new or existing concrete and parking structures.

Surface Preparation

The user should be familiar with the application instructions found on the container’s label prior to using this product. The aggregate to be used should be washed, graded, and dry prior to application. A proper inspection of the concrete is required to check for structural deficiencies, and any deteriorated areas should be promptly marked and removed. Repair delamination, potholes, and cracks with Resist Crack Treatment. The entire surface should be shot blasted or ground to a CSP #2 to #3 or depth that ensures that all deteriorated and contaminated concrete (oil, dirt, rubber, paint carbonation, laitance, weak surface mortar, etc) is removed. Remove any remaining dust with compressed air, using
a properly maintained and filtered compressor that will not spray oil or moisture onto the deck. If you pressure wash make sure the concrete is fully dry. The overlay should be applied to the surface within 24 hours of cleaning.

In the case of concrete slabs that are soft or extremely porous, a prime coat of RESIST Epoxy will be required. The prime coat applied at a rate of 200 sq² per gallon, should be treated with a light broadcast of RESIST-approved wear surface aggregate and allowed to cure prior to installing the main RESIST application.

RESIST Sand Finish Overlay may be used at a range of temperatures, however, the user should be aware that temperature plays a role in the pot life and cure times of this product. Higher temperatures will result in shorter pot life and cure times, while lower temperatures will result in longer pot life and cure times.

MIXING

1. The mixing ratio for the Resist Epoxy is 1:1 by volume (not weight).
2. Components “A” and “B” are supplied in separate containers and should be combined using a paddle mixer (powered by a low-speed electric drill) or a proportioning pump for 3-5 minutes.
3. RESIST SAND FINISH OVERLAY does not contain volatile solvents and solvents should not be added to this product
