Best Practices for Dow Paintable Silicone Sealant
Cut out and remove all old caulk for repair applications.
For best results, apply sealant at temperatures between 35 and 90°F (2 and 32°C) and when no rain or high humidity is expected within 24 hours of application.
Install back-up spacing material for better filling, especially if width exceeds 1/2" to maximize Dow Corning Paintable Silicone Sealant is available from: bonding results. Open-cell polyethylene foam backer rod can be used.
Cut snub nose above threads, reattach and cut nozzle to desired size. Insert into a caulking gun.
Extrude sealant with a smooth, steady motion, and ensure complete fill of joint cavity before proceeding.
First, apply solvent to a lint-free cloth and vigorously wipe bonding surfaces to remove dirt and residue. Then, use a dry wipe to remove remaining solvent and residue for optimum cleaning. Repeat if necessary. Surfaces must be clean, dry, oil- and frost-free for best results. (Recommended solvents include isopropyl alcohol, toluene, xylene, naphtha or similar solvent.)
Remove uncured sealant with a water-dampened cloth.
