  • Best Practices for Bostik Chem-Calk FCB Textured

    *See Terms of Use Below

    1. Application

      Install backup material or joint filler. Apply Chem-Calk® FCB urethane 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.

    2. 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.
