Mapei Elastocolor Paint is a protective and decorative elastic paint based on acrylic resins in water dispersion. Elastocolor is used to protect the surfaces of concrete and cement renders from aggressive agents present in the atmosphere.

Elastocolor, once dried, forms a very elastic film, impermeable to water, but permeable to vapour, and at the same time gives the treated structure a pleasant aesthetic appearence. Due to its elastic characteristics, Elastocolor protects and waterproofs concrete structures and renders which have hair-line cracks present as it forms a bridge over them with a strong and continuous coat.

Features & Benefits

• Once completely dry, Elastocolor Paint forms a flexible finishing coat which is impermeable to water and aggressive agents in the atmosphere (CO - SO ), while remaining permeable to vapour
• Has excellent resistance to ageing, freezing weather conditions and de-icing salts, and the photo- chemical film which forms makes it very difficult for dirt to remain attached to the surface
• Meets the main requirements of:
  • EN 1504-9 (“Products and systems for protecting and repairing concrete structures: definitions, requirements, quality control and conformity assessment. General principles for the use and application of systems”)
  • EN 1504-2 (“Protection systems for concrete surfaces”) for class:
  • Products for protecting surfaces – coatings (coating, C)
  • Protection against the risk of penetration (1.3) (protection against ingress, PI) (ZA.1d)
  • Control of humidity (2.2) (moisture control, MC)
  • Increase in resistivity (8.2) (increasing resistivity, IR) (ZA.1e)

Recommendations

• Do not use Elastocolor Paint for waterproofing horizontal surfaces, such as terraces (use Aquaflex)
• Do not use Elastocolor Paint for waterproofing surfaces which will be constantly immersed in water, such as basins, depurators and channels
• Do not dilute Elastocolor Paint with solvents
• Do not apply Elastocolor Paint on surfaces subject to foot traffic
• Do not use Elastocolor Paint for painting de-humidifying render
• Do not apply Elastocolor Paint on damp substrates, or on substrates which are not fully cured
• Do not apply Elastocolor Paint if the temperature is lower than +5°C or higher than +35°C (the surface must always be dry and must never be in direct sunlight)
• Do not apply Elastocolor Paint if the humidity level is higher than 85%
• Do not apply Elastocolor Paint if rain is imminent or in windy weather
• Prefer the use of Elastocolor Paint Plus, elastomeric hygienic paint, in case of surfaces already contaminated or particularly exposed to the degrading action of mould or algae

Application

Preparation of the substrate

Surfaces to be protected with Elastocolor Paint must be perfectly clean and solid and must be treated beforehand with Malech or, if colours with low hiding power are used, with Quarzolite Base Coat.

On surfaces where the type of curing cycle used is unsure, or if they are crumbly or have low absorbency, use Elastocolor Primer for the preliminary treatment cycle. The primed surface must never be “shiny”. Elastocolor Paint must only be applied on dry primer.

Before applying the primer coat, repair any areas in concrete which are in poor condition with controlled-shrinkage, fibre-reinforced mortar from the Mapegrout or Planitop ranges of products.

Completely remove all traces of dirt, dust, grease, oil, paintwork, saline efflorescence, mould and moss which could impede Elastocolor Paint from penetrating into the substrate.

When choosing which cleaning cycle to use, on old surfaces it depends on the type of dirt, but cold water is usually sufficient.

Cleaning the surface with hot water or steam is particularly recommended if oil or grease is present.

Sand-blasting may also be used. If the surface is not dirty, the surface may simply be brushed down with a stiff brush and blown with compressed air to remove the dust.

Elastocolor Paint may be applied on render and concrete with capillary cracks, even if they are widespread, without carrying out any special preparation operations.

Check for larger cracks and, depending on the depth, provide suitable sealing and, if necessary, levelling with Elastocolor Rasante or Elastocolor Rasante SF reinforced with Elastocolor Net.

Preparation of the product

Dilute Elastocolor Paint with 10-15% of water and mix using a low-speed drill until it is completely blended.

When preparing only partial quantities, we recommend mixing Elastocolor Paint as is in its original container before pouring off the quantity required.

Application of the product

Elastocolor Paint may be applied using traditional application techniques: by brush, roller or spray, on the dry coat of the specific primer.

For effective and complete covering of the surface, during application with brush or roller, at least two coats are necessary. Under normal humidity and temperature conditions, wait 12-24 hours between each coat, and in all cases, only when the previous coat is completely dry.

Examples of the final effect and finishes obtained using Elastocolor Paint are illustrated in the “MAPEI colours in Design” catalogue.

Maintenance after application

Elastocolor Paint may be washed with water and detergent (there are numerous products available on the market; carry out a preliminary test beforehand).

Cleaning

Brushes, rollers and spraying equipment may be cleaned with water before Elastocolor Paint dries.

Consumption

Consumption is heavily influenced by the absorption and roughness of the substrate, the colour of paint applied and according to the application technique used. Under normal conditions, consumption is generally 0.2-0.4 kg/m² per coat.
