EWIPRO External Silicone Paint – Product Description

Our EWI-005 Silicone Paint (Colour Equalisation Paint) is designed for application on skim-coat mineral plaster surfaces such as our Mineral render EWI-060. Depending on weather conditions, the product should be applied 3-7 days after the mineral render has been applied to the substrate – this will ensure proper physical and chemical bonding between the plaster coat and colour equalisation paint.

Technical Specifications:

Composition: silicon resin, acrylic binding agents, mineral fillers and pigments

Bulk density: approx. 1.57 g/cm³

Diffusion resistance coefficient μ: ≤ 1000

Water vapour permeability: ≥ 190 g/m224h

Resistance to wet scrubbing: ≥ 5000 cycles

Application Conditions:

Application temperature (air, substrate, materials): from +5°C to +25°C

Number of coats required: 1

Drying time: approx. 12 hours at +20°C

Quantity to be used for single coats: about 150-250 ml/m² (depending on the absorptive capacity, substrate structure and application method)

Directions for Use:

Surface preparation: Substrate must be clean and dry on surface. Surfaces that will not be painted must be adequately protected.

Product preparation: Paint should be checked if it matches the requested colour. Mix thoroughly paint in the container. When using more than one tin of paint for the same surface, ensure that the batch numbers are matched.

Application of the Silicone Paint: Apply using brushes, rollers or spray equipment. Paint should be applied to individual surfaces on a continuous basis to avoid colour differences. Each new portion of paint must bond to previously applied fresh coat. Depending on weather conditions, the product should be applied after 3-7 days, however, at latest after 21 days since plastering. After this period, it is recommended that Silicone Paint should be applied. In case of multi-layer plaster coats, the last layer must be 7 days old. It is usually sufficient to provide a single layer. Painting works must not be carried during rain or snow, strong winds and in direct sunlight, without special shields to limit exposure to weather conditions. Paint coat drying time is 2-3 hours at a temperature of +20°C and about 65% relative humidity. Subsequent paint coats can be applied after 12 hours. This period can be longer in low temperatures and high relative humidity, e.g. in autumn. With insufficiently dry paint coat, falling mist has the same effects as drizzle and may cause water stains and colour changes. Caution! A full selection of thermal insulaiton products should be used.

Paints with intense colours (reflection coefficient Y < 20%) should not be used for large facades; the resulting temperature and UV radiation in these conditions may reduce paint coat durability and cause colour fading.


Wash tools right away with clean water.


Shelf life: up to 12 months from the date of manufacture. Keep dry and in the original packaging at a temperature of +5°C to +25°C.

Safety Measures:

Avoid contact with skin. Wear eye protection. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. After contact with skin, wash with water. Wear suitable protective gloves and clothing.
