K Pro CRS is recommended for use as a binder for both chemical and abrasion resistant mortars and grouts. When used neat, it produces a high gloss, chemical and abrasion resistant coating for concrete or steel. K Pro CRS is recommended for use as a chemical resistant lining for tanks, sanitary manholes and secondary containment. Use it whenever a durable coating, grout or mortar is desired on floors and walls.
- Directions
Surface Preparations: Satisfactory performance of K Pro CRS is dependent upon the surface to which it will be applied. Only sound, clean surfaces should be coated. Remove all grease, oil, wax, curing compound, laitance and other foreign matter according to ASTM D-4258. Water blasting followed by shot blasting is the preferred method of preparation. Also satisfactory are sandblasting or shot blasting individually, according to ASTM D4259. Acid etching as per ASTM D-4220 with 10 15% muriatic acid solution can be used as an alternative. Be sure to rinse thoroughly with clean water to remove residue.
Mixing: Stir both components and combine into a clean container. Combining ratio for #741 pigmented is 1:1 by volume; while #740 clear has a 2 parts A to 1 part B by volume mixing ratio. Stir both components thoroughly with a paint mixer, attached to a low speed (500 rpm.) drill. Up to 4 parts loose volume, SurePoxy Aggregate may be added to produce a mortar. Mix until uniform in consistency with a low speed (400-600 rpm) drill or mixer.
Application: Apply neat with 3/8" - 7/16" nap roller, brush or spray (Graco 1:1 King with 40:1 lowers, Fixed Ratio Hydrocat, system number HC 7888 or equal). Binks model # 18 air atomized spray gun (#68 fluid nozzle, #68 PB air nozzle, #68 fluid needle, #83-5661 two gallon pressure fluid tank). Allow each coat to dry before applying next coat, however, never wait more than 36 hours before recoating. Mortar - Apply neat CRS clear to properly prepared surface as a primer. Apply mortar while primer is tacky.
Non-Slip Surface: Although, K Pro CRS is not a slippery product, it can become so, if foreign matter lays on it. To provide non-slip properties, simply sprinkle an excess, approximately 1/3 lb./ft2. of SurePoxy Aggregate Mortar on the surface of the first coat while it is still wet. When it is dry, sweep off excess and apply second coat.
Precautions: This product is not meant to be subjected to temperatures above 130°F Avoid driving or parking rubber tire vehicles or using surface for storage until K Pro CRS is thoroughly cured. K Pro CRS forms a vapor barrier after cure. Do not apply to surfaces where vapor condenses and freezes under coating. Apply when substrate temperature is 45°F or above. Do not apply over wet substrate. Concrete should be at least 3 weeks old, depending on climate. Read Safety Data Sheet before using. Please refer to the General Epoxy Instructions for complete details on proper application during cold and hot weather.
