When curing conditions will remain around or below 70°F, Sterling gloss coatings will usually require acceleration to produce a chemical cure before moisture from rain, fog, or dew causes damage to the film. It is best to complete gloss application early in the day, to prevent blushing, by the use of U-2900 Accelerator.
On warm days it is advisable to use only enough accelerator to create a tack-free surface within 15-30 minutes or so, and this may require from a few drops to 1/8 ounce of accelerator per mixed quart. Increase quantity of accelerator as temperatures drop below 70°F during application and curing periods. A maximum of 1/2 ounce of U-2900 Accelerator per mixed quart may be used under extreme conditions. Always use accelerator sparingly at first until its action becomes predictable.
