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 are appropriate for repairing joints up to 30mm. Joint Sealant N1 has 25% elasticity and is especially suitable for prime movement joints. Joint Sealant N2 has 15% elasticity.

AC-20: Non-sag, acrylic latex caulking compound for general purpose inside and exterior caulking in architectural functions the place slight to reasonable movement is anticipated; Glorious sealant for caulking inside 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.

Standard joint programs for enlargement joints on industrial floors are primarily based on polyurethanes, silicones, MS polymers or polysulphides. These are normally less resistant than the adjoining coating and vulnerable to chemical assault, quickly turning into brittle and needing to be repaired inside relatively short intervals. Mycoflex Resyst can get rid of this vulnerability. MC-Bauchemie’s product system consists of prefabricated mouldings made from a special polymer foam that is extremely resistant to chemical assault, mechanical stressing and permanent water publicity. It delivers a thoroughly dependable joint system for floors and growth joints, even the place components endure significant thermal expansion and heavy mechanical put on and tear. This makes the joint system particularly suited to a variety of industrial flooring functions, especially the chemical and oil industries and in the sewage treatment sector.
