What is chalk paint?
Chalk paints are water-based mineral paints that get their colour from slaked lime and natural pigments. For this reason, they are considered to be more eco-friendly than other paints. With this in mind, some manufacturers also avoid solvents and use natural binding agents.
The chalk pigments give the paint a porous structure. This means it does not leave behind an impermeable, sealed layer after drying. It also does not penetrate into the surface, but merely lies on top of it. When the water evaporates, the chalk pigments remain as a colour layer. Chalk paint is water-soluble and easy to sand down, which is why it is often used to create colour effects on furniture. It has a powdery, matt finish with intense colours.
