I would like to paint my front door as well as the walls around our courtyard and front porch.Can i use indoor house paint on my exterior door? Would that be ok or why wouldn't it be ok?
Interior paint is not made to withstand the weather. Exterior paint is chemically, a superior paint, and thus, it tends to cost more. Since you mention painting walls and the door... I will also add this... the type of surface you are painting will also dictate to some extent, what kind of paint you must use. I prefer enamel, or epoxy base paints for metal objects. It dries to a harder, tougher surface. For wood and other porous surfaces, I prefer to use a good oil base paint. Any good paint store can make both kinds of paint match in color if that is what you want. (Due to the chemical differences, they will go on as slightly different colors, but will dry to the same color) I wont even use interior wall paint on the 'inside' surface of a steel door... I buy enamel paint for that, and have it tinted to match if necessary.





We havent even scratched the surface between what kinds of finish you can get with paint either.... flat, semi gloss, or high gloss... typically, a door with have a 'glossier' (more shiny) finish than an interior wall.





Go down to your local paint or building supply store, and ask them about their paints, and what kind they would suggest for which surfaces, and where, you plan on painting ;)





Good LuckCan i use indoor house paint on my exterior door? Would that be ok or why wouldn't it be ok?
no it will chip off from cold and moisture
no, exterior means outside,able to withstand the elements;the paint can take being cold and hot and still remain durable.Indoor paint will not withstand the hot,cold,rain, ice, snow,sun.Not only that, but your door is probably wood or metal.Do a job big or small, do it right, or don't do it at all.Go to a paint store they will guild you in the right direction,good luck.
