While there are emulsion paints available in every hardware store, silicate paints are mainly available from specialist suppliers. The fears of contact with the mineral paint are unmistakable, although the silicate paint combines some advantages. We'll get to the bottom of the matter and present the differences clearly in tabular form.
What is an emulsion paint - and what is a silicate paint?
Emulsion paints contain finely divided plastic particles, their solvent is water. They dry physically by evaporation of the contained moisture and then form a solid film of pigments and solidified binder.
Silicate paints consist of potassium silicate glass and alkali-resistant pigments; they dry chemically by silicification with a mineral substrate. This type of color has a high pH around the value of 11.
Silicate paint vs. emulsion paint: a direct comparison
A direct comparison shows which color type is most suitable for which purpose. Here is a comparison of the most important properties:
|silicate paint||emulsion paint|
|pH value around 11||largely pH-neutral|
|fungicidal effect due to high alkalinity||only fungicidal with appropriate additives|
|can only be used on mineral substrates||can also be used on non-mineral substrates|
|only with alkali-resistant pigments can be tinted einzuf can be dyed with tinting inks from the hardware store||can etch skin and eyes when wet|
|no risk of acid burns||paint splashes attack ceramic, tiles and glass|
|splashes of paint on ceramic, glass and tiles can be easily removed||forms a vapor-permeable coating|
|limits the diffusibility of the wall to some extent fest consolidate the substrate with potassium silicate glass fest consolidate the substrate with a substrate||On non-mineral substrates, the use of silicate paints is therefore eliminated, but there is chewing for the mineral surface m something better. Only the brushing itself is a little more complicated because of the high alkalinity; especially glass and tile coverings should be protected.|
|Emulsion paints are recommended wherever there is doubt as to whether the substrate is really mineral or has already been primed with a non-mineral agent.||Tips & TricksProtect your skin and eyes as soon as you work with liquid silicate paint! Put on gloves and goggles for caustic splashes of paint.|
