Joint Sealants N1 and N2 are BS EN14188-1 compliant. They’re used to take care of horizontal joints and cracks in concrete and asphalt carriageways and airfield pavements and give a black, strong, plastic finish. They are suitable for repairing joints up to 30mm. Joint Sealant N1 has 25% elasticity and is very suitable for high motion joints. Joint Sealant N2 has 15% elasticity.

AC-20: Non-sag, acrylic latex caulking compound for common function inside and exterior caulking in architectural functions the place slight to moderate motion is anticipated; Excellent sealant for caulking inside concrete joints, hollow core ceiling and flooring planks, window and door frames, vinyl, aluminum, steel and plywood siding, sheetrock, baseboards and bathroom and kitchen fixtures.

If sealant slumping/sagging is unavoidable resulting from onsite situations, Pecora recommends installing the sealant in multiple “lifts.” A elevate refers to the appliance of two layers of sealant. For instance, where the sealant depth as measured at the middle of the joint should be ½-inch (for 1- to 2-inch broad joints), two ¼-inch layers should be put in. The primary layer ought to cure before the second layer is applied. If the sealant is silicone, the second elevate may be installed immediately over the first.

Conventional joint techniques for growth joints on industrial floors are based mostly on polyurethanes, silicones, MS polymers or polysulphides. These are often less resistant than the adjoining coating and susceptible to chemical assault, quickly becoming brittle and needing to be repaired within comparatively quick intervals. Mycoflex Resyst can eliminate this vulnerability. MC-Bauchemie’s product system consists of prefabricated mouldings made from a particular polymer foam that is extremely resistant to chemical attack, mechanical stressing and permanent water exposure. It delivers a completely reliable joint system for floors and enlargement joints, even the place components undergo vital thermal enlargement and heavy mechanical put on and tear. This makes the joint system notably suited to a wide range of industrial ground purposes, especially the chemical and oil industries and within the sewage therapy sector.
