How many coats of paint should I use?
This is a question often asked of painting contractors, and something homeowners might struggle with when completing their own projects. It depends on the nature of the project, but generally, two coats is the minimum.
Exterior Surfaces
Without question, when painting exterior surfaces, two coats of paint should be applied. Since outdoor surfaces are exposed to the elements, it’s difficult to get away with cutting corners here. Paint jobs are more prone to peeling and fading if products are misapplied, which may include only using one coat of paint or failing to properly wash, prime, etc. Painters who fail to follow these procedures do not meet industry standard. This is why it’s important to hire a contractor with a commitment to quality work. Even in the wet climate that Seattle has, a well-applied paint job can last as long as six to ten yers!
Interior Surfaces
With interior painting, we are still concerned with durability, but are more concerned about coverage. In general, we still say that two coats is a good rule of thumb. The thicker coverage provides greater durability, and also makes it easier to wash or scrub the surface if needed. Two coats are a must if you are making a significant change in color – especially if you are going for more vibrant colors. On the other hand, if you are re-painting a wall in teh same color or a very similar color, two coats will likely be fine.
The number of coats required may also change depending on the quality of paint used. Unfortunately, low quality paint does not hide well. This can result in a major headache when you have to apply multiple coasts just to get proper coverage. High quality paint has better pigments, resins, additives, and more solids. In short, this means that it hides better and lasts longer, resulting in a thicker coat.
Two coats are better than one, and a higher quality paint will save you time in the long run.
