Rasoepoxy It is a two-component epoxy system, consisting of epoxy resins. It is designed to cure even on damp surfaces, both indoors and outdoors, forming a compact, waterproof layer with high abrasion resistance. It is suitable for subsequent coating with epoxy or polyurethane finishes, or with waterproofing products from the Polyurea range.

A two-component epoxy fine mortar suitable for skimming and protecting damp concrete substrates—both vertical and horizontal—that are subject to moisture, where good chemical resistance and high abrasion resistance are required.
Substrate preparation
Substrate preparation is essential; therefore, the surface to be treated must be free from any contaminants, dry, sound, and have a tensile strength of at least 1.5 MPa. In all cases, the floor surface must be prepared by milling, shot-blasting, grinding or sanding, depending on the type of surface. Any free or standing water originating from the substrate, previous washing operations or weather conditions must be removed or dried using appropriate methods.
Product preparation
A two-component product to be mixed thoroughly at the time of use with a low-speed propeller mixer. RASOEPOXY can be used diluted with water (maximum 3%) or mixed with quartz in a ratio of 1:0.5. Mix all of component B with component A for a few minutes until a homogeneous, lump-free mass of uniform colour is obtained, taking care to avoid air bubbles.
Application
The first coat of Rasoepoxy must be applied with a trowel to seal all pores, taking care to distribute the desired quantity accurately, if necessary mixed with approx. 10% of 0.1–0.5 mm quartz. The second finishing coat must be applied as supplied. Trowelling is not recommended if a subsequent protective epoxy or polyurethane coating is planned; in this case, sanding will be necessary.
Cleaning tools
Tools must be cleaned with water after use.
When kept in its original sealed packaging, stored in a dry, sheltered place at a temperature between +10°C and +35°C, the product has a shelf life of 12 months. Keep away from frost.
