    Business Information
    Shelf Life Details Shelf life of Chem-Calk® 1200 must be checked prior to using the product, do not use past its shelf life. Caulk past its shelf life may not perform or adhere as described by this data sheet. High temperature and high relative humidity may reduce significantly the shelf life of polyurethane sealants.
    Not Good For
    Don't Use For Horizontal joints or traffic-bearing joints where abrasion resistance is required (walkways, driveways, runways, etc.), Submerged joints, Exterior or interior structural sealing below the waterline in marine applications.
    Don't Use With Concrete, Marble, Limestone, Lead, Lead coated surfaces, Zinc coated metals (galvanized), Copper, Construction materials that may exude oils, resins, plasticizers or solvents., Uncleaned or wet surfaces
  • Best Practices for Bostik 1200

    *See Terms of Use Below

    1. Design

      In general, more joint movement can be accommodated in a thin bead of sealant than a thick bead. Chem-Calk® 1200 Silicone Sealant should be no thicker than 1/2” (12.7mm) and no thinner than 1/4” (6.4mm). In joints between 1/2” and 1”, the ratio of sealant width to depth should be approximately 2:1. Sealant depth in joints between 1/4” and 1/2” should be 1/4” deep. Joints with dynamic movement should not be designed in widths less than 1/4”.

    2. Surface Preparation

      See limitations about surface preparation. Surfaces must be structurally clean, dry (no frost) and structurally sound, free of contaminants, including, but not limited to, dust, dirt, loose particles, tar, asphalt, rust, mill oil, etc. If substrate is painted or coated, scrape away all loose and weakly bonded paint or coating. Any paint or coating that cannot be removed must be tested to verify adhesion of the sealant or to determine the appropriate surface preparation if needed. (See ASP section on next page for details.) To remove laitance and any other loose material, clean concrete, stone or other masonry materials with non-alcoholic based solvent by washing, grinding, sandblasting or wire brushing as necessary. Do not use water to clean substrates. Dust must be thoroughly removed after cleaning. Alcohol is not compatible with polyurethanes and its use can cause irreparable damage to the sealant. If alcohol is used as a cleaning solvent, all traces of alcohol must thoroughly be removed prior to the installation of the polyurethane sealant. Lastly, alcohol is not recommended as a tooling medium.

    3. Curing

      Bostik 1200 is a silicone sealant. On wood, with ambient air at 50% relative humidity and at 73°F, polyurethane sealants will generally skin within one hour and cure 1/16 of an inch per day. Lower temperature and lower relative humidity will significantly increase the skin time and cure time of a silicone sealant.

    4. Clean-Up

      After dry-wiping uncured sealant from substrates and tools, remaining uncured sealant can be removed by using Xylene, Toluene or similar aromatic solvents. Please refer to the MSDSs provided for these solvents before use. Bostik® Hand Towel & Specialty Adhesive Remover can also remove uncured sealant. Cured sealant is usually very difficult to remove without altering or damaging the surface to which the sealant has been misapplied. Cured sealant can be removed by abrasion or other mechanical means (scrapers, putty knives).
