MORTAR FOR ISOLATION JOINTS
■ Outdoor exposure
■ Aboveground exposure
■ Exposure to rainwater
Isolation joints are commonly used in modern building construction in order to prevent masonry facings from cracking. Isolation joints allow walls to expand or contract in multiple directions. To allow this expansion or contraction, caulking joints are generally applied. Unfortunately, these joints are not particularly attractive.
To improve the aesthetics of isolation joints, Sika offers a polyurethane mortar. This mortar looks like a masonry joint; it is flexible, resistant to UV rays and resistant to de-icing salt.
■ Mortar recommended: King® Reconstec MF
