RussTech SEALERS are both breathable and membrane forming. SEALERS are applied when the concrete requires excellent resistance to salt and waterborne contaminants. SEALERS are designed to give the customer the option of a durable glossy or matte finish and can even resist oil penetration. Your local RussTech representative can recommend the right product for your application. SEALERS should never be applied over any other concrete coatings.


Concrete sealers are used on concrete to close up the pores in the concrete surface so it will resist water, de-icing salts, and other aggressive chemicals. Sealers are often used to prevent soiling, resist staining, facilitate the ease of cleaning, brighten concrete colors and exposed aggregates, and produce a water resistant surface. Sealers may also be used to dustproof concrete surfaces. Superior quality sealers usually consist of pure forms of acrylic resin that are non-styrenated and non-yellowing. Quality concrete sealers will last three to five years and require minimal maintenance.

A proprietary polymerized solids in a water- based V.O.C. compliant system, ready-to-use liquid that reacts with the free lime in concrete to form an insoluble crystal within the concrete pores to help repel water, de-icing salts and to seal, harden and dustproof concrete surfaces.


SilicaSeal-W is a transparent compound that:

  • Aids in minimizing efflorescence, scaling and staining
  • Reduces deterioration of concrete and masonry surfaces by helping to protect against freeze-thaw damage
  • Keeps masonry cleaning costs to a minimum and protects with one application


SilicaSeal-W gives the concrete a hard, dust free surface that resists staining and bonds securely with paint and resilient flooring mastics with the proper application. It is recommended for interior or exterior use on vertical and horizontal surfaces. It is ideal for industrial and commercial applications.

SilicaSeal-W should be used as an effective above grade barrier against the penetration of water when applied to the following:

  • Brick
  • Exterior pavements
  • Mortar
  • Concrete block
  • Concrete floor slabs
  • Concrete tilt-up panels
  • Walls & Columns
