Description
Nordsjö Murtex Silicate is a full-matt, vapour-permeable, 1-component water glass-based facade paint. Nordsjö Murtex Silicate is primarily intended for painting external and internal plastered surfaces.
It can also be used for fibre cement boards and facade brick, as well as old silicate and mineral-painted surfaces.
Product description
The substrate must be solid and free from dirt, grease, and similar contaminants. Poorly bonded or chalking surfaces should be thoroughly brushed down to a solid substrate. Cracks should be scraped open and repaired with a suitable material.
New painting: For new painting, highly absorbent surfaces, e.g., old lime-painted surfaces, must be pre-treated with Murtex Silicate Primer diluted with water 1:1. Well-bonded substrates do not require pre-treatment. Prime with Murtex Silicate mixed with Murtex Silicate Primer 2:1. Finish with 1-2 coats. Tools: Brush, roller, spray. with Murtex Silicate.
Repainting: Old loose paint must be scraped off down to a solid substrate. For best results, highly absorbent surfaces, e.g., old lime-painted surfaces, should be pre-treated with Murtex Silicate Primer diluted with water 1:1. Finish with 1-2 coats of Murtex Silicate, optionally diluted with a maximum of 10% water. When applying, cross-rolling provides the best colour uniformity. Warning! Silicate has an etching effect on glass, ceramics, tiles, natural stone, and metal. Protect surrounding surfaces against splashes, and always use safety goggles and gloves. Never paint below +10°C or at a high relative humidity (above 80%). Tools: Brush, roller, spray.
System information
2. Highly absorbent surfaces, e.g., old lime-painted surfaces, are pre-treated with Nordsjö Murtex Silicate Primer diluted with water 1:1. Well-bonded substrates are not pre-treated.
3. Prime with Nordsjö Murtex Silicate mixed with Nordsjö Murtex Silicate Primer 2:1.
4. Finish with Nordsjö Murtex Silicate, optionally diluted with a maximum of 10% water. During application, best colour uniformity is obtained with cross-rolling.

Reseal opened can well. Scrape off paint from
tools before cleaning. Do not pour paint into the drain,
not even when cleaning tools. Liquid
paint residues and washing liquid are left at an environmental station.
