Cement paint

from Wikipedia, the free encyclopedia

Cement paint or cement paints are paints , the white cement , and so-called high-hydraulic lime contain and are suitable for application to wet or moist surfaces; they are supplied as a powder and must be mixed with water before use .

Disambiguation

The part of the name cement indicates that the paint itself contains cement, and not that it is particularly suitable for cement surfaces. Cement paint is also suitable for cement surfaces, but not in a special way .

However, occasionally paints heavily loaded mineral substrates are for direct application to cement or concrete floors or similar as.. Cement colors designated; These are liquid synthetic resin dispersion paints with a special emphasis on impermeability to water and adhesion to mineral substrates.

This cement color can also be used to color cement; for this purpose, the powder is simply mixed in when mixing cement.

Conclusion: two completely different coatings with completely different properties are sold under the same name; the likelihood of confusion is nevertheless rather low, since cement-based paints are supplied in powder form and are now quite rare on the market, while paints for cement floors etc. are liquid and therefore ready-to-use and are part of the standard range of every hardware store .

properties

advantages

The highly hydraulic lime gives the paint the ability to harden without the addition of air. This makes cement paint the ideal paint for surfaces that are constantly wet or damp; it is also water and weather resistant and yet water vapor permeable. The paint can also be considered a natural color - a somewhat vague term, however - and is usually relatively inexpensive. The fact that the paint is relatively alkaline or basic gives it antibacterial, disinfecting properties.

disadvantage

  • Generally unsuitable for wallpaper , plaster (plaster or panels), wood and metal
  • relatively low opacity, usually requires several layers
  • Safety glasses and gloves required
  • relatively brittle, easily flakes off
