Tarkseal Silox SAC

Use Instructions

Apply only to untreated surfaces. New concrete must be cured 45 days. If, a cure and seal was used, it must be stripped off the concrete to allow penetration..  Adjacent surfaces such as doors, windows, and other non-absorbent surfaces should be masked before spraying to avoid contact with the impregnating solution. Tarkseal Silox SAC may be applied over itself or generic equivalents that have aged or have been applied at less than specified spread rates. A test application is necessary on each surface to be treated to ensure compatibility and desired water repellency. Test areas are also useful in determining finial application rate and procedures. If the material in the test area does not fully penetrate due to coatings or inadequately cleaned surface, use one of Tarksol’s concrete cleaners, coating stripper, degreaser, or acid etch. Two coats are recommended. Tarkseal Silox SAC will form a surface film; it is also a penetrating product. Protect new applications from rain for 4-5 hours after application for the water repellent to become effective. Tarkseal Silox SAC will react with moisture. Tarkseal Silox SAC is a fast drying VOC compliant solvent based product.

Applications

  Always apply with uniform pattern until surface is saturated and the material starts to run down or puddles. Tarkseal Silox SAC should not be diluted or altered. Apply with low-pressure (20 PSI) chemical resistant airless industrial spray equipment, however, brush or roller application is adequate where appropriate. When applying Tarkseal Silox SAC, it is suggested that the substrate receive an initial light mist coat to break the surface tension. This should then be followed immediately by a uniform flood coat which allows just enough material to carry a 4 inch rundown from contact point or flood coating on horizontal surfaces.

HORIZONTAL SURFACES: Tarkseal Silox SAC should be applied with a second coat with sufficient material applied so the surface remains wet for a few minutes before penetration into the surface. Surface residues, pools and puddles should be broomed or brushed out until they completely penetrate into the surface.

VERTICAL SURFACES:  Tarkseal Silox SAC should be applied and absorbed on the substrate to the specific coverage rate. In the case of extremely dense, mirror finish architectural concrete and similar surfaces, it may be necessary to restrict the amount of material by applying a light mist coat in order to prevent surface darkening. Allow the mist coat to penetrate the masonry surface (approximately 3-5 minutes) and apply a second coat in the same saturation manner. Apply Tarkseal Silox SAC in a flooding application, from the bottom up with sufficient material applied to provide a 6” to 8” run down below the contact point of the new spray pattern with masonry surface.

All surfaces must be clean, dry and free of grease, oil, paint, sealers, etc. To clean, use Tarksol Consolv or Tarksol Oilsolv III. Prepared concrete should have a pH between 6 and 10. All horizontal concrete must be etched with Concrete Etching Solution, prior to applying Tarkseal Silox SAC.  

Coverage Rates

Although the recommended spread rates are generally adequate, there may be variations in substrate porosity, which may require more or less material for optimum results. Apply at recommended spread rate after determining the size of the surface. With Tarkseal Silox SAC one coat is normally adequate; a two-coat application reduces the potential for inadequate coverage.
