A while back we finished the epoxy countertops for our laundry room as part of the One Room Challenge. And I had mentioned in that blog post about one of our cats jumped up on the countertop before the epoxy had fully cured. So today I wanted to share with you how to fix an epoxy countertop blemish.


The pouring of the epoxy on the countertop was the last step of the countertop process and I should have shut the door to the room during the drying process but ya know hindsight is 20/20. I am not sure which one jumped up but she went a couple steps and then realized her paws were sticking to the countertop and then she jumped down. (I didn’t witness this but by the way it looked this was my assumption.)

The countertop had several paw prints and a little bit of hair and then just general dust pieces. And if you have ever worked with epoxy you know that you need to work with it right after you pour it to get any dust or imperfections out, because as it sets, it’s going to harden.

I started Googling all different ways for how to fix epoxy and everything I was reading said that you should wait till the epoxy is completely cured, so I just left it sit with the imperfections another 12 hours overnight. I also read a lot of advice about using a sander to get out imperfections to re-do the area. So what I decided to do was to sand the small area with my orbital palm sander.

I didn’t want to have to re-pour the entire countertop or go down to the original painted surface, I want to fix the bad area. I sanded out the imperfection the best I could without disrupting the paint below, I sanded until the paw prints were barely noticeable but not completely gone.

Sanding the epoxy will take away the shininess of the surface and it will look very dull. So after I finished sanding I wiped down the surface with a damp cloth to remove any dust and let it dry. I had a little bit of paint I needed to touch up, because I had gone too far down on the corner of the countertop.

The epoxy kit from Gianni came with 3 total sets of mixer and epoxy so I mixed up another batch, and then poured it over the area that I had sanded and spread it as well as they could with the roller and paint brush. It looked good enough that I stopped because I didn’t want to fuss with it too much and then let it dry, with the door closed this time!

All in all the final patch job looks great but if you touch it you will notice a little bit of the imperfection that came from re-applying the epoxy. It feels a little rough in the areas like it didn’t level quite right.

But most importantly to me is that you can’t see these imperfections unless you are feeling the surface or you are inches away. And I don’t think anyone is going to be coming into my laundry room to “feel” the countertops!A bank of blue cabinets with gold hardware, a white marble countertop with a stainess steel sink and faucet on the left and a grey tiled backsplash

I hope this tutorial will help anyone else who may have had an imperfection show up after they have poured their epoxy.

  2. Thank you for this post. This EXACT same thing has just happened to me, and it sounds/looks like with the EXACT same epoxy kit. We don’t have any epoxy left :(.

  3. I recently got this problem as well and this article, which you can read here, taught me about the cons of having an epoxy countertop, it was also of my own negligence that it ended up this way. That’s why I’m very thankful that I came upon this blog! I’ll use your methods right away and pray that it works. Thank you again!
