What is Nox-Crete Cure & Seal 1315 A?

It is a solvent-based acrylic cure and seal sold mostly through concrete supply houses. Nox-Crete calls it an “economical high-solids solvent-based non-yellowing copolymer acrylic” (Nox-Crete data sheet). The product page gives it 25% solids.

It meets the cure and seal spec, ASTM C1315, Type 1 Class A and B, and the plain curing spec, C309. If you are new to the category, read what a cure and seal does before you pick one.

What does the 1315 A data sheet say?

It says 25% solids, about 250 ft²/gal (6.1 m²/L) for curing, two VOC versions, and exterior use only. The sheet was updated 04/29/25. “Not stated” means the sheet does not give the figure.

One conflict on the sheet: the Advantages list says dust free in 30 minutes, while the dry time table says 2 hours. Plan around the 2 hours.

Should you buy A-350 or A-700?

Buy A-350 if your area has tight VOC rules, and A-700 if you need to spray in the cold and A-700 is legal where you work. Nox-Crete says A-700 “meets all federal VOC requirements,” and A-350 “is VOC-compliant in Canada and all U.S. states but California.”

The sheet also warns that it “may be prohibited as a sealer” in some VOC districts while still allowed as a curing compound. If you are using it to reseal old concrete, check your local rule first.

Where does it fit and where does it not?

It fits exterior flatwork that you want cured and sealed in one pass with a heavier film. The product page lists residential sidewalks and driveways, stamped concrete, pool decks and parking decks. It does not fit anything indoors or enclosed, because the data sheet says its low flash point limits it to exterior use.

The flooring row matters because interior floors are where cure and seal films cause trouble. Read curing compound and flooring before you use any film-forming product on a slab that will get a covering. An AECOM quality bulletin notes that “almost all floor leveling & flooring manufacturer[s] require the concrete be free of curing compounds” (AECOM).

How do you apply it on fresh concrete?

Spray it right after final finishing, once the surface sheen is gone, to a continuous film without puddles. These steps come from the data sheet.

1. Check the temperature. Do not apply below 40°F (4°C), or if it will drop below 40°F within 12 hours.
2. Wait until bleed water has evaporated and the sheen is gone. The concrete should be damp, not wet. Spraying over bleed water can blister the film, and the risk is higher over a vapor barrier.
3. Use a sprayer with an 8006 nozzle and chemical-resistant hoses. Do not thin it.
4. Apply at about 250 ft²/gal (6.1 m²/L) to a continuous film. Avoid over-application, puddles and runs.
5. If you want a second coat, wait until the first is thoroughly dry.
6. Clean tools with xylene or Aromatic 100.

On older, previously cured concrete the sheet calls for cleaning with TSP, rinsing, letting it dry 24 to 48 hours, then applying, with a second coat 24 hours later. It is slippery when wet, and Nox-Crete sells a non-slip additive for it.

What does Nox-Crete 1315 A cost?

At Vieira Concrete, the A-350 was listed at $45.00 for 1 gal and $177.00 for 5 gal, price checked 2026-11-08. The same page showed “Not Available For Sale,” so call before you count on it. At $177.00 and 250 ft²/gal, that is about 14 cents per square foot.

Nox-Crete’s own product page showed a range of $133.98 to $1,546.55 across its 4-pack of 1 gal, 5 gal pail and 55 gal drum, checked 2026-11-08. The page text did not break that out by size.

What are the alternatives?

Pick by where the slab is and what goes on it next. The best curing compounds comparison lines up eight products by data sheet.

• Water-based, lower VOC, big box shelf: Quikrete Acrylic Concrete Cure and Seal 8730, 20% solids, meets C309.
• Water-based, lowest VOC on the shelf: Sakrete Cure ‘n Seal, 10 g/L, meets C309 when used as directed.
• Water-based cure and seal from a supply house: Dayton Cure & Seal 25% J22WB.
• Solvent acrylic, same 25% solids, by mail: Concrete Sealers USA TS200, C1315 Type 1 Class A, high gloss, under 700 g/L only.
• Interior slab getting flooring, epoxy or densifier: a dissipating resin cure such as Euclid Kurez DR VOX or W.R. Meadows 1100.

If you already sprayed it inside or on a slab getting a finish

Nox-Crete’s sheet itself says to site test before applying other sealers or adhesives over it. If the test fails, plan on mechanical removal.
