Surface Shine Gray EX

25% Solids low VOC solvent-based pigmented high-gloss sealer (ASTM C309)

Surface Shine Gray EX is a VOC compliant, gray pigmented acrylic polymer engineered to cure, seal, harden, and dustproof freshly placed and aged concrete surfaces. This product is designed with a unique solvent blend for fast-drying, solvent-base performance and VOC compliance in the OTC/LADCO/MRPO regions. It dries to a medium to light gray finish, enhancing the aesthetic and durability of concrete surfaces.

  • Dries tack-free and skid-resistant
  • 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
  • Water-based, colorless and non-yellowing
  • Low VOC formula; OTC, LADCO, SCAQMD compliant
  • Excellent oil, water, and stain repellent for interior/ exterior surfaces subjected to motor oil, de-icing salts, and other damaging contaminants

Surface Preparation

  • Ensure the concrete surface is clean, dry, or slightly damp, and free of all stains, oil, grease, dirt, and incompatible coatings.

Application Instructions

  • Ready to use; do not dilute. Apply with a sprayer in uniform thin films for best results. Two thin coats are recommended over one heavy coat to avoid puddles and ensure even coverage.
  • For curing: 300 – 400 sq ft per gallon.
  • For dustproofing and sealing: 400 – 600 sq ft per gallon.
  • Apply a second coat after the first has thoroughly dried for enhanced gloss and protection, especially on rough or broom-finished concrete.

For New Concrete:

  • Apply as soon as the surface water has disappeared and the concrete can be worked without being marred. Apply in a uniform coat, with a second coat at 400 sq ft per gallon for a superior finish and added protection.

For Existing Concrete:

  • Application will renovate 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 the original tightly closed containers. Avoid the accumulation of water, dirt, or other contaminants.


Coverage may vary based on the porosity and condition of the concrete.


  • Meets ASTM C-1315 and ASTM C 309, Type 1, Classes A&B.
  • VOC content less than 350g/l, complying with Federal AIM rule VOC requirements and regional standards for concrete curing compounds.


Clean application equipment immediately with xylene or other approved solvents after use.
