Best Practices for Bostik Chem-Calk Painter's Caulk
-
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 nonalcoholic-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.

Curing
Bostik® Chem-Calk® Painters’ Caulk is a siliconized acrylic latex caulk formulated for the professional painter. Usually tack free in 15 minutes and paintable after one hour, its low odor and dirt resistance allows for use in many interior environments. Painters’ Caulk offers outstanding adhesion and flexibility when fully cured.
-
Clean-Up
After dry-wiping uncured sealant from substrates and tools, remaining uncured sealant can be removed by using soap and water or Xylene, Toluene or similar aromatic solvents. Please refer to the MSDSs provided for these solvents before use. Bostik® Hand and Tool towels 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).
