If you’ve ever picked up a paintbrush and felt tempted to jump straight into painting, you’re not alone. Many homeowners are eager to dive right in after choosing the perfect colour, but unfortunately, this is almost always a big mistake. Rushing past the prep stage can lead to poor results. Before slapping on a coat of paint, you’ll need to repair any damage, sand the surface, tape off edges, protect your space and clean the walls.
But are all these steps really necessary? Do painters actually clean the walls before painting? Yes! Professional Winnipeg painters know that a clean surface is the foundation of a great paint job!
Let’s take a closer look at how and why painters clean the wall before painting.
Do painters clean the wall before painting?
Yes, interior painters of Winnipeg typically include wall cleaning as part of their prep work. Cleaning removes dust, dirt, grease, and grime, allowing the paint to bond directly to the surface. This results in a smoother, more durable finish that looks professional and lasts longer.
What do painters use to clean the walls before painting?
The exact paint cleaning method will depend on the condition of the walls and the room they’re in. Painters typically use:
1. Mild Soap and Water
For most walls, a mix of warm water and a small amount of mild dish soap is enough. Painters use a soft sponge or microfiber cloth to gently wipe down the walls, followed by a clean, damp cloth to remove any soap residue.
2. TSP (Trisodium Phosphate) Solution
TSP is a strong cleaner that painters use for heavily soiled walls, especially kitchens or other high-traffic areas. It cuts through grease and buildup that regular soap can’t handle.
3. Degreasers
In areas with a lot of built-up residue or visible stains, painters may use a dedicated degreaser to break down oils before painting.
After cleaning, painters always allow the walls to dry completely before applying primer or paint.
Do all walls need to be cleaned?
Yes, all walls should be cleaned before painting. However, the level of cleaning needed can vary depending on the room:
1. Low-Traffic Areas
In low-traffic areas like bedrooms or formal living spaces, walls may only need a light dusting or a quick wipe down with mild soap and water. Even if your walls already look clean, there can still be an invisible layer of dust or residue and a quick light wash can make a noticeable difference in the final result.
2. High-Traffic Areas
High-traffic areas like kitchens, bathrooms, hallways or entryways almost always require a deeper clean. These walls are more likely to have grease buildup, fingerprints, moisture, or other residues that can interfere with how well the paint adheres to the wall.
3. High-Touch Areas
Before painting, pay attention to specific spots, such as areas around light switches, outlets or door frames. These high-touch areas, as well as any other areas with visible stains or markings, will require a thorough spot clean before applying paint.
What happens if you skip cleaning before painting?
Skipping the cleaning or sanding the old paint in Winnipeg before you paint might save you some time upfront, but it can lead to disappointing results later on. Even walls that look clean often have dust, oil, grease or other debris that paint won’t stick to properly. Painting over these contaminants without cleaning can cause several issues, including:
1. Poor Adhesion
Paint may not bond well to the wall, which can cause peeling, flaking or chipping.
2. Uneven Coverage
Dust and dirt can create streaks, blotches or rough patches in the final finish.
3. Bubbling or Blistering
Grease or moisture trapped under the paint can cause bubbles that ruin a smooth surface.
4. Shorter Lifespan
Even high-quality paint can fail prematurely if it’s applied over a dirty wall.
Taking the extra time to clean the walls can save you a lot of frustration down the line! Cleaning before painting ensures a smoother, longer-lasting result.
Proper preparation is the key to a great paint job and that includes cleaning your walls. Professionals don’t just apply paint; they prep surfaces properly so they can deliver a flawless result. Ready to hire a professional painter? Contact us today at Perry Wellington in Winnipeg for a free quote!
