When To Start Painting An Exterior

20 May 2013

There are times when you know you don’t want to be painting the outside of your house right now – for example when it’s raining. However, other times it might not be as noticeable. If you decide to paint the exterior of your house when it’s too cold outside, you could wind up having to repaint, or at the very least, having to touch up again when it gets warmer out.

What Happens if I Paint When It’s Too Cold Outside?

If it’s too cold out when you paint your house, then some things can happen.
     ◾It can get a chalky look in some areas.
     ◾The dew can cause same of the paint to run in places it’s not supposed to.
     ◾You could get bubbling and blistering in between coats.
Some of these issues are easier to fix than others. Some might require a quick touch up when the weather gets more agreeable, but some problems might mean that you have to remove all the paint and start over either in the spring or summer – probably not something you were planning on!

So When Should I Start Painting?

Most paints will have a minimum temperature they can be applied at. What this temperature depends on the colour that you’re using. Not only do you need to make sure that it’s warm enough when you begin painting, but that it will stay that way while the paint sets. If the temperature drops soon after you have applied the paint, then you can run into a lot of the same problems. When you begin the exterior painting of your house, make sure that you’re taking into account both day and night time temperatures. It’s ok to start painting outside when it no longer freezes at night for at least a couple of weeks. Once the forecast looks like it’s going to be at least in the 40s during the night, then it should be safe for you to get started on that exterior project. If it looks like it’s going to be right on the fence, though, don’t risk it. Err on the side of caution and wait until you know it will be warm enough.

What about Indian Summer?

So you’ve got 1-2 weeks of unseasonably warm weather in November or even March. Go ahead, but be careful. Make sure that you apply the paint during the warmest part of the day and that there is ample time for the paint to dry before the cold, moist air comes in at night.
