HOW TO USE
Make sure the joint design is correct. Proper joint design minimizes stresses on the sealant.
Clean the joint surface on both new and old jobs. Surfaces must be clean, dry, and sound. Since new materials often comes with a protective film, solvent-wash all surface materials with a wet brush and an oil-free solvent. Use masking tape where bead lines of exact shapes are required. Masking tape should be removed immediately after a bead is completed before a skin begins to form. Apply sealant to dry, clean surfaces. An air-operated or hand operated cartridge gun may be used. Do not break cartridge seal until just before use. Surfaces in this instance should be dried before the sealant is applied. Uncured sealant may be cleaned from tools using commercial solvent. Tool joint, if necessary, and remove masking tape. Tooling should be completed in one continuous stroke. Tool immediately after sealant is applied and before the skin begins to form. Do not use soap or oil as a tool aid. Remove masking tape immediately after tooling is completed.
