 How can I fix an uneven coat of resin? It's really important to make sure that any piece that you're coating with art resin is completely level because the resin will level out regardless of what's underneath it. If your piece is slightly askew and has a little bit of a slope to it, the resin itself will be level, but then it will be uneven on either side. So how do you fix this? What you wanna do is sand everything down so it's nice and as even as you can get, then level it out perfectly. We have a level at art resin.com slash level to help you and pour another well-mixed, well-measured coat of art resin all over top. And if your piece is indeed level, then it will all work out this time round. It will fill in the gap that you saw in the first place and it'll be perfect.
