Not many of us would be aware of the fact that there is a difference, although minimal between the paints that are used for the exteriors and the ones which are used for painting the inside of the house. Ask the exterior house painters and they would tell you that one of the common differences between both is the amount of resin.
What Should You Know?
Resin is something that holds together the pigment and therefore when you are selecting the paint for outside of the house, then it has to survive the harsher conditions compared to the paint which has been put on the inside. Paints which are being used on the outside should be tough and not peel off or chip due to rain or other harsh conditions. Therefore, it becomes quite important to select the paint with the right amount of resin.
Often, we do not ask the shopkeeper and just go by our favorite shade. Eventually, you observe that the color on the outside of the house looks faded as compared to the inside even if the same shade has been applied. It is because; you have not checked the amount of resin. It is suggested to take the advice from the expert while buying the paint for the interior as well as the exterior of the house. On the other hand, paints which are used for the interiors are a little on the glossier side and delicate.
In short, you cannot consider the exterior paint to be the trade off for the interior paint and vice versa.
