Applications & Uses

Application Instructions

Preparation of substrates:

Surfaces to be bonded should be cleaned of all dust, oils or other contaminates. A solvent wipe is often adequate.
Bonds to rigid surfaces are usually improved by a solvent wipe followed with light abrasion (180 grit) and solvent wiping to remove abrasive residue. Dry surfaces thoroughly before applying sealant.

Method of application:

DC12718 All Weather Sealant can be applied by ordinary caulking guns or pressure pumping equipment. Pumping equipment should be of the follower-plate type and have a pump ratio of at least 40:1. Aro, Binks, Devilbiss, Graco and Lincoln all produce satisfactory equipment for handling this material.
Apply a bead of DC12718 All Weather Sealant to surface at temperatures above 40°F. The applied bead will self level and shrink approximately 30%, so no tooling is necessary for most applications. The bead surface will be tack free in 15 - 45 minutes, depending on ambient conditions.

Cleaner and thinner: Naphtha
