Best Practices for Bostik Chem-Calk Fast Set

*See Terms of Use Below

Application

Install backup material or joint filler, spacer shims and tapes as specified. Apply Chem-Calk Fast Set polyurethane sealant in a continuous operation using a positive pressure adequate to properly fill and seal the joint. Tool the sealant with adequate pressure to spread the sealant against the backup material and onto the joint surfaces. A tool with a concave profile is recommended to keep the sealant within the joint.
Clean-Up

Excess sealant should be dry-wiped from all surfaces while still uncured, following with a commercial solvent such as xylol, toluol, or methyl ethyl ketone. Should sealant accidentally begin to cure on adjacent porous surfaces, the excess sealant should be allowed to progress through the initial cure or setup. It should be removed promptly by abrasion or other mechanical means. Bostik recommends the use of Bostik Hand & Tool Towels for easy removal of uncured Chem-Calk Fast Set from surfaces, hands and tools. CURED SEALANT IS USUALLY VERY DIFFICULT TO REMOVE WITHOUT ALTERING OR DAMAGING THE SURFACE TO WHICH THE SEALANT HAS BEEN MISAPPLIED.
