Any person who has ever worked with epoxy resin, be it on a table, countertop, or epoxy floor, understands that the end finish matters. How clear, smooth, and shiny the surface is all relies on the sanding and polishing of the surface.
One of the questions that regularly arises is, can you use palm sander to sand seal coat epoxy? The answer is yes, you can. It can be a palm sander that can assist you in having a professional-quality surface. Apply the finest results to the right sandpaper, grit progression, and polishing techniques.
Despite the perfect pouring of epoxy, there may be bubbles, ripples, or an uneven surface. Epoxy resin flaws are fixed by sanding and polishing. The step prepares the surface you are going to apply your next coat or final polish to.
After the epoxy has hardened, it gets hard and glossy, but that is not a good surface to stick to. You should have a kind of roughness that is developed by sanding so that new layers or polishing compounds adhere well. Omission of this step may result in weak bonding of coats. You can observe smoky spots or flat spots that destroy the finish.
Yes, you can use palm sanders like magic wands on epoxy seal coats. They are lightweight and easy to handle. They create smooth surfaces for countertops, river tables, or drops with ease!
Palm sanders are the speed demons of sanding. They give a flawless finish faster than a hand can wipe. But power comes with responsibility. Epoxy is delicate and needs careful handling. Heat and friction do the job, but too much can cause issues. Holding too long or pressing too hard can leave burn marks, soft spots, or swirling lines on your work. So, sand wisely to keep your creations spotless!
Epoxy can also be polished using a palm sander. When you begin buffing change the sandpaper to a foam or microfiber foam polishing pad.
Choosing the right sandpaper for epoxy resin is key. It depends on your task: leveling, smoothing, or polishing. Each grit helps you remove flaws easily. With the right choice, you’ll keep the surface vibrant and shining.
Here’s a simple breakdown:

Let’s go through the full process of sanding epoxy resin and achieving a smooth, polished finish.
Sanding Before- Once epoxy has been sanded, it must be completely dry, and no less than 48 to 72 hours depending on the product used and the temperature. Gumming up of resin can be caused by premature sanding and surface can be spoilt.
Check for drips, bubbles, or roughness. In case of heat damage, this is how to sand burnt epoxy on a table, begin with 150 or 220 grit sandpaper, flatten the damaged epoxy, change to finer grits, and blend the surface.
Fit your palm sander with your sandpaper of epoxy. When you have a relatively flat surface, start with a 220 grit. When there are elevations or flaws then begin with coarser, that is, 120 grit.
Rotate the sander in low and smooth circles. Do not knock too hard, or stay very long in one place. It is the objective of a smooth, flat surface—not deep excision.
The same is applicable to large surfaces such as floors. Epoxy floors can be sanded easily but a bigger sander is needed with the same grit sequence.
How to polish epoxy after sanding?
Once the initial sanding has been done, clean the surface using a microfiber cloth. Look for sharp spots or shiny spots. Repeat the sanding process in case you find any. Re-sanding will bring a smooth and even surface, and then polishing takes place.
Wet sanding is then followed when the surface is flattened. Use waterproof sandpaper, spray water and sandwipe. Wet sanding helps to keep the epoxy cool, reduces dust and provides epoxy with a more smooth appearance.
Each improvement of 400 to 800 grit, wiping the slurry between.
It is time to start sanding and buffing off epoxy resin—the last polishing process. Put a bit of polishing stuff on a foam/microfiber pad. Buffing when using your hand or your epoxy sander or palm sander on low speed.
Slow, circular motions and keep the pad moving so as to avoid heat accumulation. When it comes to polishing epoxy after sanding the trick is to be patient and you will have to polish until the surface becomes glossy and clear.
When finishing an epoxy table, many people ask, “What to use for the bottom of an epoxy desktop?” The answer depends on the function.
The underside doesn’t need a mirror shine. Instead, sand it with 320–400 grit for a clean, matte finish. This prevents slipping and gives the piece stability without wasting time polishing a hidden area.
