What Is Interior Paint?
Interior paints (inside house paint) are made explicitly for internal walls and furniture. Their chemistry is different from the external paints, and these paints cannot withstand heavy snowfall, rain, or sun rays. However, they can withstand the internal lighting and the subjects they touch daily. This subject may be a chemical to clean a painted wall or any other cloth. Hence, interior paints can’t bear harsh environmental conditions.
Talking about the chemical nature, these paints are made up of liquid (mostly water), pigments, additives, and binders. These substances except water are the main reasons which make them different from the external paints. Additionally, the chemicals used in making these paints are low volatile. High VOC is not suitable for the health of humans.
Interior paints are mostly water-based, acrylic-based, oil-based, or latex-based. Water and latex-based paints are more adhesive and robust. They can work for a long time without damaging the quality of anything where these are used.
Some professionals prefer to use all these paints separately. However, some also recommend to use them simultaneously. For example, if you want to increase the shining of the walls or furniture, you can use all paints by mixing them. In this regard, you must keep sure that the color of all paints is similar.
On the other hand, some people also recommend using paint after paint. For example, if you have just applied oil-based paint and want to apply latex-based paint after some time, we highly recommend doing so. Some paints are specifically made for interior and exterior usage called indoor outdoor paint.

Pigments, Binders, and their Importance in Painting
As pigments and binders are essential parts of each painting, let’s quickly view these terms. Additionally, we will let you know how this help makes paint effective.
Pigments are substances that offer specific color to a paint which may be natural or synthetic. The natural pigments in these paints are used by extracting them from plants or animals. Natural pigments are also organic pigments which are more beneficial than synthetic pigments.
An organic pigment is better able to blend and mix 100% purely with any surface without any blender. These pigments are primarily available in dark colors.
However, synthetic pigments are made by humans using different synthetic substances. These are inorganic pigments and are less beneficial than organic pigments. All the white pigments are inorganic pigments with an insignificant proportion of titanium dioxide.
Binders are polymers of plastic that work with pigments and help create a better texture. They assist in holding up the pigments on the different surfaces.
When binders are combined with the pigments, paint becomes better able to absorb on any surface and becomes more durable. Some oil paints have binders, but these are parts of water-based paints in the most significant proportion.
