SC 100 FC-Base Coat

Application

Concrete Surface Preparation: New Concrete must be a minimum of 28 days old and possess an open surface texture with all curing compounds and sealers removed. The concrete must be clean and sound. All oil, dirt, debris, paint and unsound concrete must be removed. The surface should be prepared mechanically using sandblast, shotblast or scarifier, which will give an open surface profile of a minimum CSP3 or greater.

Steel Surface Preparation: All metal surfaces to be coated must be free of contaminants such as paint, oil and grease and sand blasted down to white metal.

Joints and Edges: If the floor is subjected to heavy wheel traffic, the edges of the floor should be sawcut 1/4” deep to locked in the edge. Moving joints as in the case of expansion joints should be maintained through the coating. All cracks over 1/16” wide should be filled. Use a
100% solids epoxy mortar to fill wide cracks, joints and keyed edges.

Mixing: All materials should be conditioned to temperature range of 60oF to 90oF. Mix parts A and part B separately for one minute using a drill and mixing prop. For ease of mixing, add 1- Part B to 2- Parts A (not the reverse). Mix the Part A and Part B together for 3 minutes. The epoxy must be well mixed to ensure proper chemical reaction. After mixing, place immediately.

Placement: This product may be applied by notched squeegee or roller. After application, it is suggested the coating be back rolled with a spiked roller to reduce surface imperfections, entrapped air and to improve bond.

Top Coat: If desired, additional coats of this product or SC 90-Clear Coat may be applied just after the initial coating has become tack-free. This could be as early as 3-4 hours, but must be within 18 hours of initial coating placement. The choice of topcoat is selected based upon
chemical and wear resistance desired. Contact your local SpecChem for specific recommendations.
