SpecChem 5 Gallon Cure and Seal 25 EX

  • Sale

25% solids, low VOC, solvent based cure and seal

CURE & SEAL 25 EX is a VOC compliant acrylic polymer engineered to cure, seal, harden, and dustproof freshly placed concrete and improve the wearability and durability of aged concrete surfaces.

CURE & SEAL 25 EX is formulated with a unique solvent blend allowing fast-drying, solvent-base performance along with VOC compliance in the OTC/LADCO/MRPO regions. 


Cure & Seal 25 EX dries much faster than standard solvent-based products. Cure & Seal 25 EX should not be applied on hot surfaces or in direct sunlight as this could cause rapid evaporation and will not allow the film to form properly. Under these conditions the film may bubble, peel and/or blush. Tip: If spraying Cure & Seal 25 EX keep pressure in pump up sprayers as high as possible to ensure a steady and even spray pattern. Maintain the prayer top near the concrete, within 12 inches.

Curing: 300 – 400 sq ft / gal
Dustproofing and Sealing: 400 – 600 sq ft / gal
Aged concrete: 400 – 600 sq ft / gal
For dustproofing and sealing benefits, apply two coats at 500 sq ft / gal. On broom or rough finished concrete, double the coverage rate. Coverage may vary due to porosity and conditions of the concrete.

New Concrete: CURE & SEAL 25 EX should be applied as soon as the surface water has disappeared and the concrete surface will not be marred by the walking applicator. At this point, apply in a uniform coat. For a superior finish and added curing and sealing protection, apply a second coat at 400 sq ft / gal.

Existing Concrete: Concrete surface must be clean, dry or damp and free of all stains, oil, grease, dirt, and incompatible coatings prior to application. An application of CURE & SEAL 25 EX will renovate existing concrete, brick or terrazzo floors. These surfaces will be brighter and easier to clean and maintain.

CURE & SEAL 25 EX is compatible with most carpets, tile and floor covering adhesives. Due to the wide variation in the chemistry of adhesives, a test section is always recommended
