Description

Silicate Paint by SecilTEK is a highly breathable masonry paint, having an Sd value of 0.01 m.

Silicate Paint provides a long-lasting, highly breathable paint for use internally and externally. Apply on a wide range of surfaces, including lime and cement based renders and stonework. Silicate paint can be used on both traditional and modern structures and is perfect for troublesome areas, such as damp basements.

SecilTEK Silicate Masonry Paint has a number of advantages over other masonry paints and washes:

• Highly breathable paint: allowing water vapour to escape from the structure whilst also being resistant to rain.
• Unaffected by UV light: conventional acrylic paints can become brittle over time.
• Exceptionally durable: a life expectancy of many years if applied correctly onto a suitable surface.
• Scrubbable and resistant to airborne pollutants and acid rain. 
• Suitable for a wide range of substrates including lime and cement renders, gypsum plasters and stonework (contact us for advice on application on to other substrates, such as existing painted surfaces).
• The solvent is water rather than petrochemical – so virtually no VOCs emitted.

The use of breathable paints is essential in traditional, solid wall constructions which may contain moisture from a range of sources.  Trapping this moisture in the walls with film-forming acrylic paints can cause serious structural and dampness problems.

SecilTEK Silicate Paint Colour Chart

• Finish and colours: A flat matt finish available in 24 hand selected colours as part of the standard range. We can also mix SecilTEK Paint in over 2,000 stunning colours, including close matches to a number of standard colour charts such as: NCS, RAL and BS4800. 
• Application: Apply with a brush or roller and dries in hours (although we advise you apply no more than one coat per day). Most applications require one coat of SecilTEK Silicate Primer followed by two coats of SecilTEK Silicate Paint.
• Size: Available in 2.5 litres and 15 litres and also in 100 ml sample tins.
• Coverage: 4-8 m²/litre per coat, depending on the surface finish and porosity.

What is an Sd value?

This Sd value is a measurement of vapour permeability which refers to the resistance shown by the equivalent thickness of air; therefore the lower the Sd value the greater the breathability. Paints with and Sd value less than 0.1 m are considered to be highly breathable.

SecilTEK Silicate Paint has an Sd value of 0.01 m.

About Silicate Paints

Silicate paints were designed at the behest of King Ludwig I of Bavaria in the late 18^th Century. Ludwig commissioned a paint that looked and worked like limewash but was more durable in the harsh winter climate. The small pore size of silicate paint allows high water vapour permeability (breathability), while at the same time these small  pores don’t allow the larger rainwater molecules to penetrate. There are instances in Germany of silicate paints lasting 100 years!

Like limewash, silicate paint soaks into the mineral substrate. In addition to this, potassium silicate (waterglass) reacts chemically to form a microcrystaline bond – a process known as silicification.

Silicate paints have a comparable thermal expansion co-efficient to a mineral substrate. This therefore minimises the stresses and damage caused by differential expansion.
