Best Liquid Sander Deglosser — Reviews and Guide

Last Updated: by Peter Lynn

When people think of sandpapers, what runs through the mind is literal paper with an abrasive surface that is rubbed on wood to smoothen it or remove paint or varnish from its surface. Initially, we also thought that way. But there is also the liquid sandpaper, call it liquid sander deglosser.

The deglosser is a liquid that is applied on surfaces to strip away its outer glossy layers and help prepare it for painting. It serves the same purpose as the traditional sandpaper in this sense.

So do you like the idea of using a liquid to “sand” your surfaces? Yes? The first step is getting the right deglosser. To establish which one is the best, read our take on the liquid sander deglosser reviews that analyze the composition and performance of different products. No need for guesswork!

The Klean-Strip Easy Liquid Sander Deglosser is our top pick, with its unique water-based formulation and fast action, this liquid sander has no equal on the market.

What is a Liquid Sander Deglosser?

At this point, we must say that the term “liquid sander” is a little misleading. In reality, there is no sanding. It is a chemical mixture that is carefully formulated to help strip off glossy layers of old furnish and paints from workpieces before a new coat of color is added.

So, the sander removes the glossy layer leaving you with a dull surface ready for new paint. Note that you should only use the sander deglosser on smooth surfaces because it cannot sand uneven surfaces.

How to Use It

For the liquid sander to degloss your workpiece, you need to apply it properly. Because you are dealing with a combination of chemicals, it is important to appreciate that even if they are water-based, there is a risk of skin and eye irritation.

So make sure to use gloves for hand protection and eye protection. Then, apply it using a disposable rug while rubbing in a circular motion. Note that there are some liquid sanders that can be applied using brushes.

Buying Guide

Often, selecting the best liquid sander deglosser is a serious challenge to many people because you are buying a formulation. See, unlike the common sandpaper that you can physically check different parameters such as grit size, it is different when it comes to liquid sanders.

But with the above four reviews, you are now closer to identifying the ideal liquid sander. Now that you know what liquid sander is and how to use it, we will now tell you how to identify the best option for your project.

Go for Water-Based

Water-based liquid sanders are recommended because they do not contain harmful chemicals. This makes them safe for both indoor and outdoor use. Particularly, you should avoid those that have flammable or hazardous chemicals that can harm your body.
