Mapei - Silexcolor Primer is a modified potassium silicate based primer in water solution. It is used to promote bonding and to even out the absorption of the substrate before final application of coloured finishes from the Silexcolor range.

Recommended Use

• Primer coat on Mape-Antique and PoroMap render.
• Primer coat on cementitious and lime-based render.
• Primer coat on de-humidifying render.

Characteristics

Silexcolor Primer is a modified potassium silicatebased primer in water solution used to make the absorption property of the substrate uniform before applying the Silexcolor finishing coat.

Silexcolor Primer penetrates deep down into absorbent substrates without forming a surface film, and without altering its water vapour diffusion capacity. Silexcolor Primer also promotes bonding for products from the Silexcolor range, and helps the silicatisation process. Silexcolor Primer helps to consolidate surface dust of the surfaces to be treated.

Silexcolor Primer is odourless and does not contain solvents, which makes it suitable for applications in closed or poorly ventilated areas.

Application Procedure

Preparation of the substrate

The surfaces to be treated must be well-cured, perfectly clean, sound and dry. Completely remove all traces of oil and grease from the surface. Seal off the porosity and smooth off any uneven parts in the substrate. Highly important: substrates must be completely free of residues of old paint.

Preparation of the product

Silexcolor Primer is ready to use.

Application of the product

Mix Silexcolor Primer well before use, and apply it using conventional techniques with a brush, a roller or by spray. One single coat is sufficient to guarantee good impregnation. Protect from rain for at least 12 hours. Silexcolor Primer may be painted over with Silexcolor finishing compounds after 12-24 hours.
