Adhesive for stairs and steps ATK 021

Adhesive for stairs and steps made of wood, metal and stone for concrete and building surfaces. It is a product to be applied over the entire step so as to eliminate subsequent stresses arising from walking. It replaces weak, low-expansion foams, which cause a deaf effect when walking, and much weaker single-component assembly adhesives. The adhesive has a strength of up to 22 Mpa - the average adhesive is only 2-8 Mpa. Importantly, it is a hard-elastic bond of materials, therefore, with changes in temperature and humidity, it allows the connection to "work". What do we glue? installation of wooden, metal and stone stairs installation of window sills other steps inside and outside What stairs can we glue? from raw and varnished wood for concrete, plasterboards, chipboards, osb, etc. from stone, e.g. marble or granite for wooden substrates, such as chipboards or metal osb with a concrete or wooden base, if you have glass steps and glue to metal, choose this glue that is perfectly transparent if you are gluing metal steps, steel, stainless steel, galvanized or aluminum to a metal frame, choose the strongest version.
