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!

If you’re planning on painting your walls, cabinets, or furniture, preparing the surface for painting can be a big hassle. To ensure that the paint sticks and lasts longer, you have to degloss (remove any glossy or shiny surface) before applying paint. Paint deglossers are popular products used for removing gloss from surfaces before painting them. In this blog post, we’ll go over what it is, how it works, and some tips on how to use it effectively.

How Does paint Deglosser work?

A 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 sanding.

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.

  1. A chemical Bond (primer/paint “melts” in with the previous finish)
  2. 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!

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 their product.

What is a good Deglosser?

My go-to liquid deglosser that works the best, in my personal opinion, is:

1: Krudd Kutter Gloss Off

Krudd Kutter Gloss Off
Get It on Amazon

2. M1 Gloss Remover

m1 deglosser for kitchen cabinets and wood paneling
Get It On Amazon

Both of these work equally extraordinarily.

The Krudd Cutter is a bit more user-friendly and has less odor in my opinion.

  1. In your article you mention that liquid sandpaper wont work on oil based paints, but that M1 product says on the label that it works on oil based paints.

    • Trust me, it’s a hit or miss. Always scuff up oil-based finishes.
