NOTICE:
•Weather conditions can cause unsatisfactory results when spraying some coatings.
•High humidity prolongs set, and cure times.
•High temperatures decrease set, and cure times.
•Cold temperatures extend set, and cure times.
•Variations in temperature, and humidity can cause variations in finish quality.
•Coating manufacturers can recommend additives to resolve some of these problems, and should be contacted for assistance with particular problem resolutions.
