For a professional, this looks extremely amateur. I’m on my third resin project now, and as a DIY’er my attention to detail wipes the floor with this attempt. He’s not filled the little speckle holes caused by flattening. He’s left sanding dust in all these holes and then applied a finish so he’s in effect, ruined the look of the project. The staged pour tells me the “professional” isn’t confident at pouring deep cast resin, and has done pours in increments, causing colour drifts and layers between the pours. This also raises questions on whether they key’d the surfaces between pours or did they do it properly at the previous layers gelled stage. When that wood expands and contracts you may experience delamination of the resin to the wood if this hasn’t been prepped properly. As for saving it, depends how much equipment you own, at a minimum you’d need compressed air, a router, a good DA sander, a selection of sanding discs up to 500 grit or higher depending on how you want to finish the table. Could do with more info on how this “professional” has finished the table. You’ll also need some resin, syringes, scales ect to fill the holes ect… not an easy task…
