Degreasing walls before painting - how to get perfect paint adhesion
Many people think that a wall is clean enough to paint with a quick cloth, soapy water or a quick vacuum. But appearances can be deceptive. Even when a wall looks neat, there is often a layer of grease, dust, cooking fumes or smoke residue on it. Especially in kitchens, living rooms and around radiators, dirt imperceptibly sticks to the surface.
Are you going to paint directly over this? Then the paint will adhere poorly, absorb unevenly and quickly develop streaks, spots or even flaking paint. Therefore, degreasing walls before painting is always a necessary step for a smooth and durable end result.
Why degrease?
Many people think that a wall, door or window frame is ready to paint after a quick cleaning. Unfortunately, a layer of grease, dust, skin oil or cooking vapour almost always remains, even if you don't see it. And exactly that layer makes for poor adhesion.
If a substrate is not properly degreased, paint:
- streaky dry up,
- form spots or circles,
- cover less well,
- or even loosen or flake after a short time.
By degreasing before painting, you ensure a clean, grease-free base on which paint really takes. The result? A smooth, durable paint layer that stays nice longer. So degreasing is not an extra step, but a necessary preparation for any successful paint job.
Which tools work - and which ones don't?
Many DIYers reach for remedies that seem logical, but in practice actually worsen the problem. Here's why:
Dishwasher detergent or all-purpose cleaner
Sounds convenient, but leaves a greasy film on the wall. Paint then adheres even worse.
Ammonia
Degreases well, but is unhealthy to work with and the acrid smell is unpleasant. In addition, it corrodes some surfaces.
A professional paint degreaser
This is the only solution that gets walls really grease-free without damage. A good degreaser completely breaks down grease and adhesive layers and leaves no residue.
How do you degrease your wall?
A wall may sometimes appear clean, but it almost always contains grease, dust or smoke residue, especially in the kitchen, living room and around radiators. If you paint over this, the paint will adhere poorly and you will get streaks, stains or even flaking paint later.
With the right approach and a professional degreaser, you will make the wall really paint-ready.
- Mix about 50ml of the product with a bucket of water (warm water increases the degreasing effect of the product).
No need to dilute it with water - Clean and degrease the substrate with a sponge or cloth
- With light soiling and light use of the paint degreaser, the substrate is directly paintable
- For heavier soiling, first wipe off the paint degreaser with a damp cloth
- Be a Picasso and start painting

Common mistakes when degreasing walls
Even experienced handymen make mistakes during degreasing. These are the most common:
- Not enough degreasing: a suds cleans but does not degrease. This results in poor paint adhesion.
- Do not rinse: residues of cleaning agents form a film layer that hinders adhesion.
- Working too wet: too much water can saturate the wall and later cause blistering under the paint.
- Do not let dry: a damp wall leads to poor adhesion and uneven drying.
Extra tip: include wooden surfaces immediately
Are you going to paint doors or window frames in addition to walls?
Then degrease it at the same time, so you get an even result.
For wood, there is a special product that works even better:

After degreasing: preparation for painting
Degreasing is step one. Then comes the preparation that makes the difference between “reasonable” and “professional”:
- Light sanding for extra grip
- Fill holes and cracks with wall filler
- Masking edges with masking tape for clean lines
After that, the wall is really ready to paint.
