Kaufman Products SureSeal OTC

Quality sealers are composed of film forming resins or binders that provides the wear, durability, and chemical resistance; pigments (when desired) provide color; and thinners that evaporate but are needed to make an easily applied liquid material. The difference between ordinary sealers and floor paints is the amount and type of resin or film former used. Typically, sealers contain anywhere from 150-200% or more film formers than paint. This is why a properly applied floor sealer will outlast a properly applied paint.

SureSeal OTC provides a long-wearing film to protect the floors from abuse, from a wide variety of foot and vehicular traffic, chemicals, etc. It reduces dusting of a concrete floor to provide a clean atmosphere in which to work. Inventory and equipment stay clean and look better. Maintenance is considerably reduced, since dirt stays on the surface for easy removal. Use it in schools, offices, hospitals, clubs, warehouses, manufacturing plants, and commercial office buildings. When used on floors to receive tile or carpet, SureSeal OTC reduces the quantity of adhesive necessary.

Apply 2-3 coats at 400-600 ft2/gallon per coat.

Surface Preparation: The satisfactory performance of any coating system is directly related to the preparation taken to the surface to be coated. Only apply to sound, clean surfaces. Surfaces should be cleaned thoroughly. Remove all dust, wax, grease, oil and all foreign matter according to ASTM D-4258. If smooth, dense troweled concrete, then sand blasting and mechanical scarification according to ASTM D-4259 are the preferred methods of properly preparing the floor and removing laitance.

Acid etching as per ASTM D-4260 with a 15-20% muriatic acid solution can be used. Be sure to rinse thoroughly with clean water to remove residue.

Application: Stir pigmented SureSeal OTC before use. Apply by brush, roller, or paint sprayer. Test small area first for correct application procedures. On rough surfaces, use a long nap roller. Thin the first coat by up to 15% with SAC. Apply 2-3 coats at 300-500 ft2/gallon. Allow each coat to dry before applying subsequent coats. The use of spiked rollers helps to reduce bubbles in film.

Non-Slip Surface: When a non-slip surface is desired, sprinkle approximately .25 lbs./ft2 of SurePoxy Mortar Aggregate on the surface of the first coat while the coating is still wet. After the coating dries, sweep off loose material to save for reuse, then apply the second coat.
