Recently, I had the opportunity to remove damaged sealants and old stains from painted wooden surfaces without creating a mess. My woodworker colleagues whom I consulted with actually discouraged using standard sandpaper on wood surfaces, suggesting that liquid sandpaper could be a better option if used correctly.
If you’re curious how to employ method effectively like I did, I’ll share key steps on how to effectively use liquid sandpaper.
What is Liquid Sandpaper?
Applying liquid sandpaper simplifies wood preparation as an alternative to traditional sandpaper for paint jobs. It is also referred to as a deglosser or wet sanding products which have similar chemical solutions to those in the market.
Its solution can be mild because it is composed of ethyl acetate, ethyl alcohol, and naphtha. For the stronger version, look for solutions with TSP or Tri-Sodium Phosphate. Either solution can remove undesirable materials on the surface.
However, this is not your wood product to fill the holes and cracks or make a unique finish on the surface. Liquid sandpaper is used to restore the natural appearance of wooden furniture, tables, and floorings without completely stripping the paint.
How it Works
These chemical solutions work like paint strippers, but they will not penetrate the wood. It does not eliminate the paint except that it only softens the top surface or layer of the painted wood.
This means it will weaken a sealer or any finishing product you use on the painted surface, making it easy to wipe off and letting your new paint and sealer product adhere more effectively.
Liquid Sandpaper vs. Traditional Sandpaper
But how does liquid sandpaper differ from regular sandpaper? Although they are both useful in wood preparation, they have a wide array of different uses and characteristics.
With its role and how it works, why would you choose this over the traditional method?
In my experience, liquid sandpaper is easier to use than traditional. It only takes half an hour or at least 15 minutes to finish removing the top coat. But, to work with the traditional, you need to make an elbow grease effort which will result in muscle pain and fatigue.
Also, by using traditional sandpapers, you are susceptible to inhaling dangerous dust from the painted wood. You can also eliminate the mess from the dust produced by ordinary sandpaper if you are using it.
Most importantly, regular sandpaper has limitations on reaching the small and complicated areas like curves, holes, and carvings of the wood. But, if you are going to use it for these areas, you can rub off the paint or sealer easily.
Liquid sandpaper can save you time and effort for your other wood projects and paint jobs.
Using Liquid Sandpapers Effectively: 7 Simple Steps
Knowing how to use liquid sandpaper beforehand can make your task easier. Refer to the steps below to start your project.
Materials You’ll Need
Before you begin, you need to prepare the following materials.
After preparing the materials and selecting your well-ventilated work area, you can start your wood preparation.
Step #1: Start by Preparing the Surface
Make sure that you have removed the extra dirt on the surface by washing it with soap and clean water in a circular motion. You can use either hand or dish soap. If the previous smooth surfaces are full of filth, use a stronger cleaner.
Afterward, I let this dry by using a dry towel or rag. You can opt to air dry for at least 15 minutes. Remember that the surface should be 100% dry so you can have the best result.
Step #2: Then, Begin Applying the Liquid Sandpaper
When the surface is cleaned thoroughly, you can apply the liquid sandpaper. Using your brush or lint-free cloth, spread the deglosser on the surface. For recessed areas, I recommend using a smaller brush. Make sure that you apply it slowly and in easy strokes.
Step #3: Leave the Liquid Sandpaper to Dry
Drying your liquid sandpaper is recommended before the second layer. The recommended time to soften the top layer of the painted wood is indicated in its container or bottle. Make sure you got the timing right.
Step #4: Don’t Forget to Check the Surface
Different liquid sandpaper products require different removal methods, so make sure you check the surface to see if it can already be rubbed off. Using a clean rag or cloth without lint, dry off the surface.
Step#5: Apply the Second Layer of Liquid Sandpaper (If Needed)
After wiping off the painted wooden surface, I look to see if there are remaining sealers or top coats that need to be removed. If required, you should do a second layer of liquid sandpaper.
Step #6: Allow the Liquid Sandpaper to Dry
Again, give it time to soften the surface, and refer to the manufacturer’s instructions to ensure you do it right. Then, rub off using a clean cloth.
Step #7: Coat the Surface with Paint or Stain (Optional)
If you have removed the damaged top layer of the painted wood, you can apply a new coat of paint or stain. This is optional if you still need to fill the holes and imperfections on the surface.
How to Use Liquid Sandpaper on Cabinets
When you are going to remove the varnish or glossy surface in your cabinet, using liquid sandpaper is better than common sandpaper. Here’s how to use it on kitchen cabinets.
Make sure all the surfaces are clean before applying the deglossers using a clean and lint-free cloth. Leave the solution for 15 minutes before you rub it off with another cloth. Normally, a single layer of wet sandpaper can remove the existing sheen.
Liquid Sandpaper Advantages
The works of liquid sandpaper are wonders for woodworkers whose time and effort are precious, and so are yours. Therefore, here are the advantages of using it.
Quick to Use
As I mentioned earlier, using it can save both time and effort. This is the most effective wood preparation if you have a line of things to do for your wood project. You can exert your effort to other procedures for your wood project.
Allows Ease of Application
Once you apply the liquid, all you have to do is wait and rub it off until the result is achieved. The application only requires a brush, a cloth, and a chemical solution. It is an apply and rub wood preparation.
No Dust Particles
Unlike ordinary sandpaper, which could make your work area full of dust, a liquid detergent does not produce dust particles. According to studies, high exposure to dust can trigger allergies and irritations on the skin as well .
The versatility of liquid sandpaper updated the application of chemical solutions to areas that ordinary sandpaper cannot reach. Using the right tool, a smaller brush and tiny cloth can push to the recessed areas.
In my line of work as woodworker, I definitely value clean and tidy workspaces. When dealing with old stains and sealants on painted wooden surfaces, using a cloth soaked in liquid sandpaper not only took care of those issues but also effectively cleared away other residues on surfaces, even those with uneven textures.
One major perk I noticed when employing liquid sanders is that I could do away with the traditional tarp that I regularly use when working with regular sandpaper.

How to Pick the Right Liquid Sandpaper
Dozens of liquid sandpaper are promising, but you should know how to pick the right one. Here’s what you need to know before buying it.

Essentials Tips When Using Liquid Sandpaper
Despite its many benefits, do not forget that it is composed of chemical solutions that are hazardous to your health and the environment. So, I listed here the safety standards from experts:
Don’t Forget to Protect Yourself, Your Family, and your Pets
Liquid sander emits volatile organic compounds (VOCs), which are hazardous if we breathe them in. It can cause asthma and allergies, but sometimes extreme symptoms like nausea, dizziness, and brain damage if exposed frequently.
To protect your family and self, wear safety masks, gloves, and goggles. Some medical stores offer masks and goggles that can protect both your eyes, nose, and mouth by wearing a single protective item.
It can also be harmful to your pets if it’s roaming near your work area. So, make sure your pets are distant from your work area. It is highly toxic, and it can burn your skin if accidents occur.
Therefore, you should start by choosing the proper work area. It should be a well-ventilated area and have no obstructions from your pets and children.
Read and Follow the Manufacturer’s Instructions Carefully
The sole purpose of a manual is to guide properly and give the dos and donts on using the product. The instructions and labels on the container are imperative to read and follow.
Manufacturers’ customer responsibility is to provide their customers with warnings and directions on how to use the product. So, read and follow the instructions and labels carefully.
Dispose of Any Remaining Product Properly
Included in the instructions of manufacturers is to dispose of it properly after you use it. It means you need to separate it from regular trash and dispose of it at your community’s hazardous waste sites.
Refrain from flushing the containers in your sink or your toilet bowl. It will eventually pollute the environment via waterways.
