Features & Benefits

- Technical Characteristics
- Dursilite is a modified acryl resin-based washable matt paint in water dispersion with selected charges with good covering properties and a high whiteness level for internal walls.
- When applied on internal surfaces, Dursilite bonds perfectly to all types of masonry, render, smoothing and leveling compounds and old paintwork, as long as it is well attached and is not crumbling.
- Dursilite protects the substrate and gives it a highly attractive, uniform matt finish which is velvety to the touch.
- Dursilite is available in a wide range of colors, created using the ColorMap® automatic coloring system.

- Where to Use
For painting all types of new, old and painted internal surfaces where an attractive finish with a smooth, velvety, matt surface is required. The product has low dirt pick-up and a high whiteness level. To paint partially-covered external surfaces protected against direct sunlight and rain. The product’s special formulation makes it particularly suitable for painting all types of cementitious, lime and gypsum substrates which require a high degree of longlasting protection and excellent permeability to water vapor which are easy to clean.
- Some Application Examples
- Painting all types of internal walls and new, well-cured or old cementitious, lime and gypsum render and smoothing and leveling compounds, as long as they are regular, well-bonded and have no flaky or crumbly areas.
- Painting old and new external cementitious surfaces, including those already painted, as long as they are not exposed to particularly aggressive climatic conditions (such as the back-face of balconies, stair wells, pillars and ceilings below covered areas, flat roofs, balconies and internal parapets on terraces)
- Application Procedure
Preparation of the substrate
- Surfaces 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 attached. Seal all cracks and repair areas which are deteriorated. Seal the porosity and smooth over uneven areas on the substrate with mortars and skimming compounds from the MAPEI Building line.
- Apply Malech or Dursilite Base Coat. Dilute Malech with water according to the type of substrate (cementitious, gypsum or lime based); as a general rule, it is suggested a diluition Malech/water in a ratio of 1/1 for more absorbent substrates and 1/2 for less absorbent substrates, in order to avoid the forming of a glassy film on the wall surface. Apply Dursilite Base Coat white or colored in a shade similar to the final color, particularly in case of bright colors that normally have poor covering properties (such as bright red, yellow or green). Wait until Malech or Dursilite Base Coat are completely dry (6-12 hours) and apply Dursilite.
Preparation of the product
Dilute Dursilite with 15%-20% of water, making sure that it is thoroughly blended. Use a low-speed drill for blending if possible. When preparing only partial quantities, we recommend mixing Dursilite as is in its original container before pouring the quantity required.
Application of the product
Apply Dursilite with a brush, a roller or by spray on a dry coat of Malech or Dursilite Base Coat primer. The cycle comprises the application of at least two coats of Dursilite with a recoat time of 6-12 hours, according to humidity and temperature and, in any case, when the previous coat is completely dry.
Cleaning
Brushes, rollers and other tools used to apply Dursilite may be cleaned with water before the paint dries.
- Precautions to be Taken Before Application
- Do not apply if the temperature is lower than +5°C.
- Do not apply if the level of humidity is higher than 85%.
- Do not apply on external surfaces exposed to rain or direct sunlight.
- Do not apply on damp substrates, or on substrates which are not fully cured
- Consumption
Consumption is heavily influenced by the absorption and roughness of the substrate, by the color applied and according to the application technique used. Under normal conditions, consumption is generally 0.3-0.4 kg/m² (for two coats of the product).
