Joint Sealants N1 and N2 are BS EN14188-1 compliant. They are used to keep up horizontal joints and cracks in concrete and asphalt carriageways and airfield pavements and provides a black, strong, plastic end. They are appropriate for repairing joints as much as 30mm. Joint Sealant N1 has 25% elasticity and is very appropriate for top movement joints. Joint Sealant N2 has 15% elasticity.

AC-20: Non-sag, acrylic latex caulking compound for normal function inside and exterior caulking in architectural applications where slight to moderate movement is anticipated; Glorious sealant for caulking interior concrete joints, hollow core ceiling and ground planks, window and door frames, vinyl, aluminum, steel and plywood siding, sheetrock, baseboards and bathroom and kitchen fixtures.

If sealant slumping/sagging is unavoidable because of onsite circumstances, Pecora recommends putting in the sealant in a number of “lifts.” A elevate refers to the application of two layers of sealant. For instance, the place the sealant depth as measured at the center of the joint needs to be ½-inch (for 1- to 2-inch large joints), two ¼-inch layers should be put in. The primary layer should cure earlier than the second layer is utilized. If the sealant is silicone, the second elevate could also be installed directly over the first.

Typical joint programs for growth joints on industrial floors are primarily based on polyurethanes, silicones, MS polymers or polysulphides. These are usually much less resistant than the adjoining coating and susceptible to chemical assault, shortly changing into brittle and needing to be repaired within comparatively brief intervals. Mycoflex Resyst can eradicate this vulnerability. MC-Bauchemie’s product system consists of prefabricated mouldings made from a particular polymer foam that is highly resistant to chemical attack, mechanical stressing and permanent water exposure. It delivers a totally dependable joint system for floors and growth joints, even where components undergo vital thermal expansion and heavy mechanical put on and tear. This makes the joint system notably suited to a variety of industrial flooring functions, particularly the chemical and oil industries and in the sewage remedy sector.
