Does paint Deglosser work?
Yes, Liquid paint deglosser/ liquid sander works on previously painted gloss surfaces but before you go jumping into painting your next glossy surface you need to understand how deglosser works and when you should use it! Liquid sander will NOT work on oil-based paints. You will have to scuff and use an oil-based primer for that!
How Does paint Deglosser work?
Liquid sander is a specially formulated solution that you can apply to a glossy painted surface or polyurethane to take the sheen off and ideally paint over that surface without having to sand.
The solution causes a chemical reaction that breaks up the density of the finish and therefore it loses its gloss.
Now when you prime or paint over the deglossed surface, you will create a chemical bond between the surface and primer/paint.
There are 2 types of bonds you want to create when painting.
- A chemical Bond (primer/paint “melts” in with the previous finish)
- A Mechanical Bond (primer/paint “locks” in with a scuffed up surface)
A mechanical bond is created when the surface is scuffed up to create a tooth for your paint to bite into.
The average deglosser has an operating time between 3-7 days.
If you wait longer you risk not creating that chemical bond.
Then you would have to apply it again.

How to use liquid sander deglosser?
Pour your liquid sander into a clean bucket.
I like using a green Scotch-Brite pad to scuff up the surface at the same time.
This pad is coarse enough to get the job done without damaging the surface.
I let it sit for 5-10 minutes before wiping down everything with a clean damp rag.
I suggest you always wear latex gloves and protective glasses!
These Pads Are Optimal
Is liquid sandpaper the same as Deglosser?
Although there are different names for deglosser, liquid sandpaper is the same product.
Different brands have different names for the product.
What is a good Deglosser?
My 2 go-to liquid deglosser that work the best in my personal opinion are:
1: Krudd Cutter Gloss Off
2. M1 Gloss Remover
Both of these work equally great.
The Krudd Cutter is a bit more user-friendly and has less odor in my opinion.
