Pre-Paint Checklist: Humidity

Why You Must Check Your Humidity Levels Before Painting

If unchecked and unaccounted for, humidity can affect the quality of your paint job.

 

Painting your walls and ceilings seems like a straightforward task, even considered therapeutic by many. The tangible experience of transforming your space with colour surely has an emotional layer to it. And those emotions can go both ways, depending on the experience.

 

To ensure your paintjob is a positive one, it’s important to do the preparation work before you even purchase your paint. Checking the condition of your space lets you spot and eliminate any issues that could affect your painted surfaces if left unchecked. One key area to check: humidity.

If It’s Wet, It Won’t Set!

Walls and ceilings are actually porous at the microscopic level. Over time, moisture and alkalis can permeate the surface, while forcing themselves between the wall and the paint coat, reducing it’s adhesion to the wall.

 

What does this lead to? Peeling walls. Uneven, discoloured paint coats. Bubbles forming on walls. Not very pleasant situations. But fortunately, all avoidable with a bit of foresight and prep!

 

Knowing the current humidity and moisture levels of your space, you can make the necessary fixes. At the end of the day, you’ll have beautifully painted walls that last.

Your Humidity Checklist.

If your surfaces have a high moisture content, you’ll want to first apply sealer to the surface before painting. Sealer enables good adhesion between the substrate and new paint, which helps prevent issues like peeling.

 

If possible, test your walls with a substrate moisture meter. If you have a contractor or vendor working with you, they should be able to do this.

 

If not, these questions are a good indicator of a humid room:

 

  • Is your air-conditioning turned on for more than 8 hours a day?

 

  • Do you live in coastal areas?

 

  • Does your surface have mold or a chalky texture to it?

 

  • Are your walls damp to the touch?

 

  • Have your walls previously had water condensation problems?

 

If you’re answering ‘yes!’ to any of these questions, we recommend using sealer, and then cair (cair fresh is less effective at humidity regulation)!

Now you know, you can control. Tackling humidity, you’re on your way to an awesome paint job!

Some Additional Tips:

Because of the humid climate we live in, any extra effort to inhibit moisture’s effects on your walls goes a long way.

Doing these extra preparation steps gives you walls that paint will adhere very well to:

  1. Spackle any holes, let them dry. Sand down any bumpy areas.Clean the wall of any loose materials like dust or cobwebs. Vacuum, or use a lightly damp cloth and wipe the entire surface. Paint adheres best to a clean, dry wall. (Use a wiper mop to clean hard to reach areas!)
  2. Before opening the paint, give it a good shake so the pigments are evenly distributed.

Dilution: If needed, you can add up to 15% of clean water to the paint. Give it a good stir for even consistency when painting.
