Professional Application Tips

Surface Preparation

Power wash thoroughly, repair all seams and penetrations, and allow surface to dry completely. This step is critical for coating adhesion and warranty coverage.

Weather Conditions

Apply when temps are 50°F and rising with no rain expected for 24-48 hours. Avoid application in direct hot sun or when dew is expected.

Mil Thickness

Follow manufacturer specifications for wet mil thickness. Most silicone coatings require 20+ mils for warranty coverage. Use a wet mil gauge during application.
