I found the perfect chair for my porch. Or maybe your kitchen cabinets need a new coat of white to match your new backsplash. The problem? The current finish was too glossy. The paint won’t stick. It beads up and runs off like water on a duck’s back.
Conventional wisdom says you need to grab a sanding block. Elbow grease is required. A sufficiently thick mask is needed to protect against lead dust. You want a vacuum cleaner that won’t clog in 5 minutes.
There are chemical shortcuts. It’s called liquid sandpaper. Sometimes called deglosser or wet sanding. The glossy surface layer is removed, so the new paint has better grip.
But it’s not magic. It won’t smooth out dents. It does not fix scratches. It is only for removing shine. If you’re tired of breathing in drywall dust or sanding intricate woodwork, this might be the answer.
Why choose a deglosser instead of physical grinding?
Ordinary sandpaper physical abrasion. It grinding the surface. Liquid sandpaper is chemical. It dissolves the shiny surface layer.
What is the biggest advantage? No dust.
If you have furniture made before 1978, the dust may contain lead. Grinding creates a cloud you breathe in. A Liquid deglosser keeps these particles where they should be on the cloth. Completely eliminates respiratory risks.
It also protects your wrists. Sanding a large dresser is exhausting can be tiring. Rubbing a chemical solution the chemical solution with a rag. Just use it. Wait. Wipe it off.
Then there are the details. That wainscoting with the deep grooves? Sanding these corners with paper is a nightmare. The paper gets stuck. It tears. It misses spots. Liquid sandpaper gets into every nook and cranny. It hits the designs that were not possible with traditional tools.
Limitations you should know about
Don’t buy expecting miracles. Liquid sandpaper only does one thing. Dims the shine.
You cannot fill in the blanks. Uneven wood cannot be made smooth. If the surface is rough, uneven or scratched, sandpaper is your only ally. Deglosser cannot solve this problem. It just becomes shiny-less and shiny.
Not even a primer. Do not mistake it for a bonding agent. It removes the barrier (gloss) and prepares the surface, but does not in itself improve adhesion. You also need paint. Depending on the color change, you may need to apply a primer underneath for best results.
How to use liquid sandpaper correctly
Although the process is simple, skipping a step can ruin the final effect.
1.Clean the surface
Start with a bare surface. Wash the item with soap and water. Removes oil, wax and dirt. When you use a deglosser on stained wood, the sealing the dirt in. Dry thoroughly with a lint-free cloth.
2. Apply the Solution
Dip a clean, lint-free cloth in liquid sandpaper. Rub it into the surface. Cover everything you plan to paint. If the product is large, Work in sections. Consistent coverage is required.
3. Wait
Patience is key here. Check the sticker. Depending on the product, it can take about 5 minutes. Others require thirty. Don’t rush. It takes time for the chemicals to break down the shiny layer.
4.Wipe Off
Take a fresh cloth. Wipe off any residue. Removes dissolved polish and by-products of chemical reactions. Use a dry cloth to ensure the surface is ready for painting.
Safety and ventilation
These chemicals are very strong. They smell. They burn.
The fumes are potent. Open windows. Turn on fans. If you are in a small room with no air flow, stop. Go outside or into a garage with an open door.
Wear gloves. This solution may irritate the skin. Wear safety glasses. You do not want this in your eyes.
The risk of fire is real. This solution is highly flammable. Keep away from sparks, pilot lights and open flames. Also dispose of used rags safely. Oil-soaked rags can spontaneously combust if piled up. Lay them flat to dry before throwing it away, or store it in an airtight metal container.
