Dayton Superior J22WB and J11W Curing Compound Review

This review is built from Dayton Superior’s two data sheets, not from field trials or star ratings. No affiliate links are on this page. To see these two next to other products, use the best curing compounds roundup.

What are Dayton J22WB and J11W?

They solve different problems. Cure & Seal 25% J22WB is “a water based acrylic copolymer containing 25% solids” that cures, seals and dustproofs, drying to “a non-yellowing, durable, clear film” with a high gloss (Dayton Superior). Dayton calls it ideal indoors because it is low odor and nonflammable.

Clear Resin Cure J11W is “an all resin, dissipating water-based curing compound” for horizontal and vertical concrete. Its membrane “will begin to dissipate after exposure to sunlight, weathering and/or traffic” (Dayton Superior). For how that class works, see dissipating curing compound.

What do the Dayton data sheets say?

These are Dayton’s published numbers. “Not listed” means the sheet gives no figure.

The J11W sheet also says it is “Tested and compliant per CDPH V1.2” and approved by “numerous state highway departments,” with separate product codes for TxDOT and Illinois DOT orders. Ask for the code your agency lists.

Where do J22WB and J11W fit, and where do they not?

Pick by what goes on the slab next. J22WB is the finish; J11W is a cure that gets out of the way.

Both sheets point to ACI 302.2R before moisture-sensitive flooring goes down. Neither product makes the flooring maker’s own approval unnecessary.

How do you apply J22WB and J11W?

Both go on once the free water is gone and the surface cannot be marred. Both sheets say do not delay and do not thin.

For J22WB:

1. Agitate before each use. Do not use high speed mixing equipment.
2. Use a low pressure sprayer, roller or brush, or Dayton’s Spray-Pro power sprayer.
3. Apply uniformly without puddles at 200 to 400 ft²/gal for the first coat.
4. Add the optional second coat at 400 to 600 ft²/gal for longer life and more gloss.
5. Clean tools with water while wet.

For J11W:

1. Stir before each day’s use. Do not use high speed mixing equipment.
2. Spray if you can; Dayton calls spray the preferred method. A roller also works.
3. Hold 200 ft²/gal on broom finish and 400 ft²/gal on tight troweled concrete.
4. On walls, spray two light coats with a fine tip, the second while the first is wet.
5. Clean tools with warm soapy water before it dries.

The J11W sheet warns that “Cool, damp conditions and/or over application may extend drying and dissipation time.” Do not lay it on heavy to be safe.

If you need to coat or floor over J22WB or J11W

Indoors, J11W will not clean itself. The sheet says that for “interior applications not exposed to weathering and sunlight the Citrus Cleaner J48 is to be used to remove the curing membrane.” Budget that step in the bid rather than waiting for it to wear off.

How much do J22WB and J11W cost?

On 2026-11-08, Certified MTP listed a 5 gal pail of J22WB at $267.02, a 5 gal pail of J11W at $88.08 and a 55 gal drum of J11W at $627.50. All three showed an estimated ship time of 2 to 3 weeks.

J22WB costs about three times as much per gallon because it is a 25% solids sealer, not just a cure. The J11W pail page said it ships as hazardous material by heavy freight, not small parcel.

What are the alternatives to Dayton J22WB and J11W?

For a dissipating cure like J11W, W.R. Meadows 1100 and Euclid Kurez DR VOX fill the same slot. For a cure and seal like J22WB, compare solids and C1315 listing before price. The best curing compounds table lists standards, rates and sizes side by side.
