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 give a black, solid, plastic end. They’re appropriate for repairing joints up to 30mm. Joint Sealant N1 has 25% elasticity and is very suitable for top motion joints. Joint Sealant N2 has 15% elasticity.

AC-20: Non-sag, acrylic latex caulking compound for normal purpose inside and exterior caulking in architectural functions where slight to moderate movement is anticipated; Wonderful sealant for caulking interior concrete joints, hollow core ceiling and floor 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 circumstances, Pecora recommends putting in the sealant in a number of “lifts.” A lift refers to the application of two layers of sealant. For instance, where the sealant depth as measured at the center of the joint needs to be ½-inch (for 1- to 2-inch wide joints), two ¼-inch layers must be put in. The first layer should cure earlier than the second layer is applied. If the sealant is silicone, the second raise could also be put in directly over the first.

Conventional joint techniques for growth joints on industrial floors are primarily based on polyurethanes, silicones, MS polymers or polysulphides. These are usually less resistant than the adjoining coating and vulnerable to chemical assault, shortly becoming brittle and needing to be repaired within relatively quick intervals. Mycoflex Resyst can eliminate this vulnerability. MC-Bauchemie’s product system consists of prefabricated mouldings made from a special polymer foam that is highly resistant to chemical attack, mechanical stressing and permanent water publicity. It delivers a thoroughly dependable joint system for floors and expansion joints, even where elements suffer vital thermal enlargement and heavy mechanical wear and tear. This makes the joint system significantly suited to a wide range of industrial ground applications, particularly the chemical and oil industries and in the sewage treatment sector.
