Description
1.5 GALLON
ML819 CONCRETE PRIMER/SEALER is a 100% solids, solvent free epoxy compound designed for use either as a stand-alone sealer or as an undercoat for Concrete Patch and Slip-Not. It is approved for use in food processing plants. It has been formulated to provide deep penetration into the surface without the use of solvent, thus eliminating any objectionable solvent odor, particularly inside buildings or around food processing or storage areas. It fills small voids and hairline cracks, and helps seal air entrained concrete to prevent “out gassing”. Concrete Primer/Sealer is also a stand-alone concrete sealer which can be applied in one or two coats and provides a tough, durable, hard film which prevents dusting and deterioration of concrete surfaces and the effects of water, chemicals or freeze/thaw cycles. This product can be applied to damp or moist surfaces without affect to performance.
DIRECTIONS FOR USE:
1. Follow concrete Surface Preparation Guide to assure all loose and unsound concrete, contaminants, and other foreign deposits are removed.
2. Add 2 parts Base (Part A) to 1 part hardener (Part B) by volume (or all of both containers if entire batch is being used). Mix well using a power mixer for approximately 2 minutes.
3. For best results, apply by roller, using a medium nap, phenolic core roller cover. Apply an even, wet film while working material into surface. Do not allow material to puddle.
4. Spread rate will be approximately 200 to 400 square feet per mixed gallon, depending upon porosity of concrete surface.
5. Concrete Primer/Sealer can also be sprayed applied, followed by “back-rolling” the material into the surface, or be applied by squeegee. Small areas can be brushed using a pure Chinese bristle brush.
