Description
12-34 NSF is a clear, water-based concrete curing compound that is
formulated to ensure proper concrete strength development, prevent shrinkage cracks
and leave a bondable surface for further coatings, treatments or flooring. 12-34 NSF will
not discolor concrete surfaces, nor does it need to be
removed before applying further surface coatings. 12-34 NSF is a premium
cure, sealer, hardener and dustproofer for new or aged concrete surfaces.

Application
NEW CONCRETE:
Horizontal floors and slabs: After bleed water has disappeared and surface can
support the weight of the applier, apply 12-34 NSF with a low-pressure
sprayer such as a Chapin sprayer equipped with a fan tip that produces a flow of 0.3-0.5
gal. (1.14-1.89 L) per minute under 40 psi (0.276 MPa) of pressure in a uniform
and continuous manner. (See prescribed coverage rate table at left.) Avoid
over-application. Do not allow material to puddle on concrete surface.
Vertical concrete: After stripping vertical framework, immediately apply
12-34 NSF with a sprayer. Hold spray tip approximately 2 feet from the
surface and apply in a uniform and continuous manner at 400-500 sq. ft./gal. Do not
apply when temperature is below 40°F (4°C). Do not apply 12-34 NSF
over free-standing water.
SUBSEQUENT COATINGS:
Allow new concrete to cure for 28 days before applying paint or other coatings.
Application procedures do not supersede further surface coatings – see
manufacturer's instructions.

Limitations
- Do not dilute or alter in any way.
- Must be agitated prior to use.
- Do not dilute or alter in any way.
- Do not apply to frozen surfaces or when temperature is below 40°F (4°C).
- Protect material from freezing.
- If white crystals begin to develop, this is an indication that too much
material has been applied. Rinse over applied areas with water and squeegee off
remaining puddles.
- If material is sprayed on glass or other finished surfaces, quickly wipe up
with warm soapy water.
- May not be suitable on colored concrete applications. Always perform a small test
or mock-up.
- Check with coating manufacturers for their preparation guidelines. These
instructions do not supersede their guidelines.

Cautions
Always wear protective goggles and gloves when using this product. Do not take
internally. If swallowed, do not induce vomiting. Contact a physician immediately.
If eye contact occurs, flush eyes with fresh water for 15 minutes and contact a
physician. Wash all exposed skin with soap and water after use. Keep out of the reach
of children.
Shelf Life
1 year in unopened container. Store above 40°F (4°C).
Cleaning
12-34 NSF may be cleaned from equipment using soap and warm water. If
material is accidentally sprayed on metal, aluminum, glass or painted surfaces, rinse
immediately with water.
