Water based paint

Water based paints contain microscopic plastic particles of binder, filler and pigment, dissolved in water. Water based paints are water soluble, but become water-resistant when dry. As a binder, different types of material are used like acrylic, vinyl, PVA or alkyd.
Water based paints have many advantages over oil paints. They offgas much less organic fumes (VOC’s) than oil paints because they don’t need an organic solvent.
Synthetic waterbased varnishes are however not free of harmful substances. They contain agents that can emit VOC’s, such as antibacterial, anti mildew, quick drying or conservant agents.
Water based paints dry more quickly and are more elastic then oil based paints. They are more suitable for application on wood because they allow the wood to shrink and expand without letting cracks occur. Generally they need more layers to be fully opaque compared to oil paints,

	Quick Dries fast. Non toxic Low VOCs and no solvents.

	Non toxic It contains low amount of VOCs. Offgassing is minor compared to oil based paints. It is always better to check the amount of VOC in the ingredients. Under 50g/l it is considered low, under 5 g/l it is considered zero.		Tips When evaluating offgassing it is important always to consider also the amount used, the surface painted, and the other surfaces where the same paint has already used in the same room. \\\\\\\”Low VOC does not mean ‘non-toxic’ but a lower quantity of volatile organic compounds (VOCs) that create smog in the environment\\\\\\\” (1). If a low VOC’s paint is choosen, it is important to check the ingredients. If for instance, the same low VOC’s paint is used for several fornitures, floors and walls in the same room, the total amount of VOC’s can be hazardous in that environment. Latex or water-based paints labeled ‘quick drying’ can emit formaldehyde (2).

		Difficult recycling Even if it is not a hazardous waste, it cannot be disposed as regular trash. If there's less than one-fourth of the paint in the can, take it outside, place it where kids and pets can't get to it, remove the lid and let the paint air dry. When the paint is hard (it is turned into solid waste) you can put the cans out with the rest of your trash (1).
