Earthborn Eco-Pro Silicate Paints are a durable and highly breathable alternative to conventional masonry paint and limewash that dries to a classic, matt finish. This is supported by a water based primer to stabilise loose, powdery or absorbent surfaces.
Formulated for use on lime render and other mineral surfaces.
Unparallelled lifespan: creates a chemical bond.
Low acrylic content: exceptional breathability.
High alkalinity: deters algae growth.
10ltr tub weighs 15.6kg
What are Silicate Paints?
Developed over 100 years ago this type of paint has been tried and tested over decades so you can be assured that you will not be using some new wonder paint that turns out not to be so wonderful. They comprise of mineral fillers with an algicide and pigments in a binder of potassium silicate. They work in a different way to conventional masonary paints which create a film over the surface. Silicate paints penetrate the substrate and form a chemical bond with it - a process called silification. This ensures a very high rate of moisture vapour permeability.
How long will it last?
Its durability is one of its key benefits. After an initial primer coat and 2 topcoats it will last up to 15 years before requiring another coat. Compared to a limewash which usually requires a fresh coat every 2-3 years it is also a very cost effective alternative.
Where can I use silicate paints?
Because of the way the paint bonds it can be used on mineral surfaces such as lime render/plaster, brick, cement render and stone. The surfaces must be bare and any previous paints removed. It is possible to use a silicate paint over previously limewashed backgrounds ensuring that the limewash has been brushed down and is not dusting or flaking. They are mainly used externally but because of their durability they are often used internally on historic properties which recieve a high level of traffic such as stairwells where a limewash would require frequent reapplications.
