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

AC-20: Non-sag, acrylic latex caulking compound for basic function inside and exterior caulking in architectural applications where slight to average motion is anticipated; Glorious 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 as a result of onsite situations, Pecora recommends installing the sealant in a number of “lifts.” A elevate refers to the applying of two layers of sealant. For example, the place the sealant depth as measured at the center of the joint must be ½-inch (for 1- to 2-inch broad joints), two ¼-inch layers should be put in. The primary layer ought to cure earlier than the second layer is applied. If the sealant is silicone, the second elevate could also be installed straight over the first.

Standard joint methods for expansion joints on industrial floors are primarily based on polyurethanes, silicones, MS polymers or polysulphides. These are usually less resistant than the adjoining coating and weak to chemical assault, rapidly becoming brittle and needing to be repaired inside 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 very resistant to chemical assault, mechanical stressing and permanent water publicity. It delivers a thoroughly reliable joint system for floors and expansion joints, even where parts suffer significant thermal growth and heavy mechanical put on and tear. This makes the joint system significantly suited to a wide range of industrial floor applications, particularly the chemical and oil industries and within the sewage remedy sector.
