Question posted - November 26 to December 2, 2012:

How do you keep sealants in control joints from cracking or separating from the substrate?

Selected Answers

From Ken Johnson of Heritage Preservation on November 29, 2012:
      Proper joint design and substrate preparation are the best solutions. A properly designed joint will not exceed the elasticity to the jointing materials. Surface preparation of the substrate is very important. Sealants will not adequately bond to dust,dirt and moisture that may may lie upon the surface of the substrate. When in doubt, use a primer, even when the manufacturer's data sheet indicates that one is not required.
