Not sure if we want to use or not?What is mineral paint?
It’s probably the kind of question that if you asked 10 different painters you would get 10 different answers. The truth is no one really knows, from a scientific point of view it is not a paint term at all it is just a word that has been used to describe a decorative furniture paint in short it’s nothing more than clever marketing.
Titanium dioxide (white) is the most common pigment found in almost every paint that has ever been made and it is a natural earth mineral pigment so technically speaking all paints are mineral paints?
It is also commonly used as a food colouring.
What is chalk paint?
Again if you asked 10 people most would say it’s a furniture paint but ask them to elaborate on this and that’s probably as far as they can go.
From a scientific point of view this again is not a paint term just more clever marketing.
Calcium carbonate (chalk) is one of the main ingredients found in chalk paint, if it didn’t have this in it it probably would not be chalk paint at all? But calcium carbonate is found in the majority of paints, it is what a paint chemist would term as a “filler” Fillers are usually cheap and inert materials like calcium carbonate, talc, quartz sand and others, they are used in all paints that serve to thicken the film, support its structure and increase the volume of the paint.
Chalk type paint has more fillers than most other paints which is why it is usually much thicker than most paints.
A decorator might know a high filler content paint as a contract or obliterating matt usually used for base coats due to it being cheap and cheerful but not prized because of its porous nature which is why chalky type furniture paints require a sealer after application.
All paints contain fillers (chalks) so are all paints chalk paints?
What is milk paint?
This one you may have a better chance of getting a straightforward answer to although many might say it’s a paint made from milk! Which we guess is true ish. It is paint made from casein a milk protein usually mixed with borax and lime which is needed to activate the casein and act as a preservative, borax is found mainly in detergents
Normally milk paint comes in a powdered form and then mixed with water this is because milk paint in its liquid form does not have a long shelf life, Once water is added, the lime/borax activates the casein and yields a durable but caustic paint that can be used only on porous surfaces, milk paint is not designed to be used over previously painted surfaces and is only long lasting when bonding direct to the sub-strate.
Milk paint has been around for thousands of years and is the one really true scientific term used for describing a paint out of the decretive paints we have mentioned.
Lime and borax are also both minerals so we guess it is a mineral paint too?
The four main ingredients to all paints are pigments, binders, liquids and additives
(I can expand on this) might be good for a section to say what makes a paint?
