Poly-Alphamethylstyrene Concrete Curing Compounds
DESCRIPTION
The 2200-WHITE series includes 2245-,
2250- and 2255-WHITE. These ready-to-use concrete curing compounds are high
solids, white-pigmented, poly-alphamethylstryene-based. These formulations were
developed for various Departments of Transportation as premium-grade concrete
curing compounds. The 2200-WHITE series offers rainfall protection typically
within four hours of application, developing sufficient hardness and film integrity.
The 2200-WHITE series is white-pigmented to reflect the sun's rays. This maintains cooler concrete, that reduces the expansive and contractive stresses which cause cracking during the hydration process. When properly applied, each product in the 2200-WHITE series provides a tough, smooth, uniform film with excellent adhesion to the fresh concrete surface.
All products in the 2200-WHITE series meet maximum VOC content limits of 350 g/L for Concrete Curing Compounds as required by the U.S. EPA Architectural Coatings Rule.

APPLICATION
Surface Preparation
If the surface of the concrete is clean and free of foreign
matter, no further preparation is required. If foreign matter, such as dirt
and dust, has accumulated on the surface, it should be removed before applying
the compound. If surface moisture has evaporated, as in the case of formed concrete,
or the concrete is beginning to dry out, best curing is obtained if the concrete
is wetted before application of a 2200-WHITE series product. NOTE: The concrete
surface should be moist, but free of standing water. Once the concrete will
accept walking workmen without marring, the surface is ready for the application
of any 2200-WHITE series product.
Mixing Any settling in the drums can be re-dispersed with gentle agitation prior to use. CAUTION: TO AVOID FOAMING, DO NOT MIX EXCESSIVELY.
Apply curing compound to the surface of the concrete with spray equipment as soon as possible after the moisture has left the surface. Spray equipment should be capable of spraying a smooth, uniform coat.
Workmen should not track across freshly poured concrete until after the concrete is coated with the curing compound and the film has dried thoroughly.
Drying Time The product dries in approximately one hour. Restrict foot traffic for at least four hours.
Clean up Clean equipment promptly with mineral spirits or other suitable petroleum distillate.
PRECAUTIONS
Do not apply on interior surfaces. Do
not apply when the temperature of the concrete is less than 40° F (4°
C). DO NOT MIX "WATER-BASE" COMPOUNDS WITH ANY COMPOUND CONTAINING
SOLVENT - SEPARATION WILL OCCUR.
