For Best Results:

Not for use as a structural sealant. Not for use in place of appropriate through-wall flashing. Not for use below grade or in locations designed to be continuously immersed in water. Do not apply to surfaces with standing water or frost. Pressure-treated lumber should be wiped with a solvent wipe prior to product application. Keep containers closed and out of direct sunlight when not in use. In low humidity conditions, curing may take longer than 12 hours. Lightly misting treated surfaces with fresh water will accelerate curing. If air or surface temperatures exceed 95°F (35°C), apply to shaded surfaces and before daytime air and surface temperatures reach their peak. Hot surfaces may be cooled with a mist of fresh water.
