Mapei Mapecoat ACT 021 is suitable for the painting of new, old and already painted internal surfaces with specific hygiene requirements. Mapecoat ACT 021 complies with the requirements of the HACCP protocol for painted walls and ceilings in areas where food is present. Application examples include the food industry and public and private environments serving food and drinks (bars, restaurants, supermarkets, schools and company canteens, etc.). Resistant to mould.
Mapei Mapecoat ACR 021 is also ideal for protecting and decorating cementitious, lime and gypsum-based substrates that require a high level of hygiene and prolonged resistance to cleaning operations, painting of internal walls and new, well-cured or old cementitious, lime and gypsum-based plaster and skimming mortars, as long as they are sound, wellbonded and have no crumbling areas and painting of rooms that need to guarantee a high level of hygiene combined with long-term durability and ease of cleaning.
Mapecoat ACT 021 also contains BioBlock® technology which actively blocks the formation and spread of mould, making it particularly suitable for protecting areas
difficult to reach during normal cleaning operations, such as ceilings.
Surfaces to be painted must be well cured, perfectly clean, sound and dry. Remove all traces of oil and grease from the surface and any parts which are not well bonded. Seal all cracks and repair any damaged or deteriorated areas. Seal surface pores and level off uneven areas of the substrate with mortars from the MAPEI Building line. Apply a coat of Mapei Malech transparent bonding promoter diluted with water. The amount of water required depends on the type of substrate (cementitious, lime or gypsumbased, etc.) and its level of absorbency. As a general guide, it is recommended to dilute Malech 1/1 with water for more absorbent substrates and 1/2 for less absorbent substrates.
For bright colours that normally have poor covering properties (such as bright red, yellow or green) use Dursilite Base Coat coloured undercoat in the same colour,
diluted with up to 5% of water. Wait until the Malech or Dursilite Base Coat are completely dry (6-12 hours) before applying Mapecoat ACT 021.
Dilute Mapecoat ACT 021 with 0-10% water, depending on the application method used and the condition of the substrate. When diluting the paint make sure it is
thoroughly blended. Use a drill at low speed for mixing if necessary. When preparing only partial quantities, it is recommended to mix Mapecoat ACT 021 undiluted in its original container before pouring off the quantity required.
Apply Mapecoat ACT 021 with a short-pile roller, by brush or by spray on the dry coat of Malech or Dursilite Base Coat. The complete cycle requires the application of at least two coats of Mapecoat ACT 021; wait 6-12 hours between each coat at normal temperature and humidity conditions, and in all cases wait until the previous coat is completely dry.
