CaO + H2O -------> Ca(OH)2 + heat + hissing ( paint mixed with water) (initially looks rough)
Ca(OH)2 + CO2 ------> CaCO3 + H2O
(Calcium Hydroxide reacts with Carbon dioxide to form Calcium Carbonate)
(CaCO3 is bright white)
As paint dries through the process of oxidation the reaction produces heat, which is an exothermic reaction.
What dries fast is not so much the paint, but the fresh plaster on which the fresco paint is applied. And as the plaster dries the paint unites with it.
Only if it dries out.
Most paint dries faster on wood.
Your paint should dry to the exact color of the sample, if it does not, the color was mixed wrong. When you apply a fresh coat of the same color paint, it goes on lighter, and darkens as it dries.
No, the drying of paint is considered a physical change, not a chemical reaction. The drying involves the evaporation of the solvent in the paint, and it is not an exothermic reaction because it does not involve the release of heat.

Paint bubbling is not typically due to a chemical reaction but is more often a result of moisture or heat causing the paint to blister and bubble. This can happen when there is improper surface preparation, such as painting over a damp or dirty surface. If the bubbling is not addressed, it can eventually lead to peeling and flaking of the paint.
Latex paint is water-based and dries quickly, while acrylic paint is chemical-based and dries slower. Acrylic paint is more durable and flexible, making it suitable for a variety of surfaces, while latex paint is better for walls and ceilings.
Yes, acrylic paint is flexible when it dries.
No, because the paint simply sits on the surface of the wood, and there is no change to the molecules in the wood. Therefor, it is a physical change, until its dries then its a chemical change.
What dries fast is not so much the paint, but the fresh plaster on which the fresco paint is applied. And as the plaster dries the paint unites with it.
Physical, no chemical reaction is occuring, your just covering the Iron with paint, the paint doesn't react with the iron.
Only if it dries out.
Latex paint is water-based and dries quickly, while acrylic paint is a type of plastic-based paint that dries more slowly and is more durable.
