Finishing treatments facilitate maintenance and increase strength. Some of MA’s Materials, like wall concrete or clay, require no finishing and can be left bare. But for many others, such as micro-mineral concrete, finishing plays an essential role for the protection and beauty of the material. Wax or varnish give patina to the material and determine its matt, satin or gloss aspect. A good finish is an essential element for the sustainability of a coating, and allows easy maintenance. MA’s varnishes, in aqueous phase and certified A +, are suitable to each application. High performance varnishes, highly resistant to stains, are dedicated to intensive uses (shops, restaurants, kitchens, bathrooms). Patinas, varnishes and coloured mineral impregnators allow to play on decorative effects. Properties Two-part colourless polyurethane finishing varnish for interior and exterior protection (consult us) of floors and walls. Visco No. 7 varnish consists of a base (Part A) and a hardener (Part B). It forms a highly durable film that is solvent-free and does not yellow. It protects cements and epoxy resins. Its viscosity provides a way to check that the base and hardener were correctly mixed. And its whitish appearance during application provides a way to see which surfaces have already been coated so that bare areas can be avoided. Preparation of the substrate The floor must be clean and dry. On raw concrete, clean using MA’s cleaning acid for new screed and cement clouds, and then rinse with water. On varnished concrete to perform repairs, sand using 120 grade sandpaper before application.
