Surface Shine Gray

25% solids solvent-based cure & seal (ASTM C309 compliant)

Surface Shine Gray is a VOC compliant acrylic polymer designed to cure, seal, harden, and dustproof both freshly placed and aged concrete surfaces. This product, with its light gray pigmented acrylic sealer, dries to a medium to light gray finish, enhancing the aesthetic and durability of concrete surfaces.

  • Colorless and non-yellowing
  • Long-lasting protection for new as well as old concrete and stone surfaces
  • Reduces water penetration minimizing the effects of freeze-thaw and weathering on concrete structures
  • Dries quickly, tack-free and skid-resistant
  • Low VOC (< 100 gm/l) formula; SCAQMD, OTC, LADCO, compliant
  • Fast drying and can be recoated
  • USDA accepted for indirect food contact
  • Excellent oil, water and stain repellent for interior/exterior surfaces subjected to motor oil, de-icing salts and other damaging contaminants

Surface Preparation

  • For optimal adhesion and performance, the concrete substrate should be free of contaminants and either clean and dry or slightly damp. Dense, hard-troweled concrete should be profiled or roughened to enhance adhesion.

Application Instructions

  • Ready to use; do not dilute. Apply with a sprayer for uniform thin films, which is the preferred method for best results. Apply two thin coats, allowing the first coat to thoroughly dry before applying the second. Never apply one heavy coat to avoid puddles.
  • Coverage for curing: 300 – 400 sq ft/gal.
  • Coverage for dustproofing and sealing: 400 – 600 sq ft/gal.

For New Concrete:

  • Apply as soon as surface water has evaporated and the surface can be worked without being marred. Apply in a uniform coat, and for enhanced protection and finish, a second coat can be applied at 400 sq ft per gallon.

For Existing Concrete:

  • Ensure the surface is clean, dry, or damp, and free from stains, oil, grease, dirt, and incompatible coatings. Application will enhance the appearance of existing concrete, brick, or terrazzo floors, making them brighter and easier to maintain.


  • Available in 5 gallon pails.

Shelf Life

Two years from the date of manufacture when stored in original tightly closed containers. Avoid accumulation of water, dirt, or other contaminants.


  • Meets ASTM C-1315 and ASTM C 309, Type 1, Classes A & B.
  • VOC content less than 700 g/L, complying with EPA limits and regional standards for curing and sealing compounds.
