ClearGrip Coatings

ClearGrip concrete floor coating systems combine the ease of installation with the required toughness and durability for challenging industrial and chemical environments.

In addition with this toughness and durability ClearGrip concrete floor coating systems can be installed in a variety of existing colors. ClearGrip coatings, offer some of the best stain protection in the market and are highly chemical resistant.

INSTALLATION

Surface Preparation

Always mechanically prepare (profile) surface. An open, porous surface is necessary for proper bonding. The surface must be deemed structurally and mechanically sound, clean, and dry. Proper surface preparation is required for decorative-concrete, thin-film “Class-A-type” flooring systems or sealer/finish coatings. This is best achieved with mechanical grinding machines using diamond heads achieving a final 30 to 100-grit profile. Recommended surface profile is a CSP-2, Reference ICRI Technical Guideline No. 03732. Surfaces to be coated must be free of sealers, grease and any other contaminants that may impede adhesion. Always check the surface for any bond inhibitors prior to application. Do not use Alcohol to clean or tack substrate or previous coat prior to application. Any repairs must be addressed prior to application and should be repaired in accordance with ICRI standards. A moisture emission measurement system is necessary to assess the moisture drive of a concrete slab prior to installation of any toppings or coatings. The relative humidity of the slab must not exceed 75% as tested per ASTM F2170 Relative Humidity in Concrete Slabs test. If there is a moisture emission situation in excess of the above rate, use professional grade concrete moisture vapor barrier. The application process will depend on the system being installed, reference appropriate specification for details.

Pigmented Coatings:

Add full contents of ClearGrip Polyaspartic Pigment directly into short filled Part A pigment base. Mix pigment into Part A with a slow speed drill mixer for 2 minutes to fully disperse the aspartic pigments. Failure to properly mix pigments may lead to an inconsistent finish and reduced product performance.

Mixing Part A with Part B:

Mix part A and part B in equal parts (1:1) using a clean, dry working vessel. Stir with a drill mixer on slow speed for 2 minutes. Avoid overmixing or creating a vortex that would introduce air. Do not mix below the dew point, which will shorten the pot life. No induction time is required prior to use. If micro-media agents (e.g. ClearGrip Blended Quartz Aggregate) are to be incorporated, they are to be added after thoroughly mixing A and B. Product may be thinned up to 10% with Xylene. Do not use alcohol at any point during application of the system.

Flat or foam squeegee application is recommended with a double perpendicular back-roll. Roller must have an industrial grade phenolic resin core with a synthetic nap or lambs-wool cover. 3/8” (10 mm) nap. Small chip brushes may be used along the perimeter and in more difficult to reach areas. ClearGrip will typically be dry to the touch 1 to 2 hours after application, dependent on ambient temperature, slab temperature and humidity. Product may be recoated at that time or when deemed appropriate by system specification. Foot traffic is generally acceptable after 2 to 4 hours with
24 hours minimum required for vehicular traffic.
