Joint Sealants N1 and N2 are BS EN14188-1 compliant. They’re used to keep up horizontal joints and cracks in concrete and asphalt carriageways and airfield pavements and provides a black, solid, plastic finish. They’re appropriate for repairing joints up to 30mm. Joint Sealant N1 has 25% elasticity and is especially suitable for prime motion joints. Joint Sealant N2 has 15% elasticity.

AC-20: Non-sag, acrylic latex caulking compound for common purpose interior and exterior caulking in architectural purposes the place slight to average motion is anticipated; Glorious 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 due to onsite situations, Pecora recommends installing the sealant in multiple “lifts.” A lift refers to the appliance of two layers of sealant. For instance, the place the sealant depth as measured at the middle of the joint should be ½-inch (for 1- to 2-inch huge joints), two ¼-inch layers ought to be put in. The primary layer should cure before the second layer is utilized. If the sealant is silicone, the second lift could also be put in straight over the primary.

Standard joint programs for enlargement joints on industrial floors are based on polyurethanes, silicones, MS polymers or polysulphides. These are normally much less resistant than the adjoining coating and vulnerable to chemical assault, quickly changing into brittle and needing to be repaired within relatively brief intervals. Mycoflex Resyst can remove 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 completely dependable joint system for floors and enlargement joints, even where elements endure important thermal expansion and heavy mechanical wear and tear. This makes the joint system significantly suited to a wide range of industrial flooring functions, especially the chemical and oil industries and in the sewage remedy sector.
