Silicate Paint provides a long-lasting, breathable paint finish both internally and externally. It can be applied onto a wide range of surfaces, including lime and cement based renders, gypsum plasters and stonework. It can be used on both traditional and modern structures and is ideal for troublesome areas, such as damp basements.

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.

For most purposes, apply one coat of SecilTEK Silicate Primer and two coats of SecilTEK Silicate Paint.  SecilTEK paint is easy to apply with a brush or roller and dries in hours (although we advise applying no more than one coat per day).

SecilTEK Silicate Masonry Paint is a flat matt finish, and is available in over 60 colours (including white)

Silicate paints have an interesting history. They were designed at the behest of King Ludwig I of Bavaria in the last 18th Century. Ludwig commissioned a paint that looked and worked like limewash, of which he was a great admirer, 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 minimises the stresses and damage caused by differential expansion.

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 being resistant to rain.
✔︎ Unaffected by UV light: acrylic paints can become brittle over time.
✔︎ Very durable: a life expectancy of many years if applied correctly onto a suitable surface.
✔︎ Resistant to airborne pollutants and acid rain. 
✔︎ Suitable for a wide range of substrates including lime and cement renders, gypsum plasters and stonework. Please contact us for advice on other substrates such as existing painted surfaces.
✔︎ The solvent is water rather than petrochemical – so virtually no VOCs.
✔︎ Scrubbable: ideal for high-traffic areas.
✔︎ Over 60 great colours (including white).
✔︎ Main UK distributor: we supply SecilTEK Silicate Masonry Paint at unbeatable price.

Whats an Sd value?

This refers to the resistance shown by the equivalent thickness of air; so the lower the Sd value the greater the breathability. Paints with Sd values less than 0.1m are considered to be highly breathable. SecilTEK Silicate Paint has an Sd value of 0.01m !!

*Whilst we try to ensure the consistency of our colours between batches, we strongly advise ordering sufficient quantities as a single order to avoid slight differences in shading.
