Hello, I’m in the UK and for a few weeks have been trying to make a dining table using epoxy resin. I have had a few issues along the way and now I am stumped with the final polyurethane top coat. I sanded the table thoroughly prior to application and I made sure I didn’t apply too much by rolling over the coat with 2 dry foam rollers yet the end result still has the orange peel effect.
How can I fix this issue? should I;
1. Wet sand the coat with 2000grit then polish the coat?
2. Wet sand the coat and add another few layers before sanding and polishing?
Also can I sand just one layer of PU and then polish or should I add multiple layers? if so when adding extra layers of PU should I sand each layer with 2000grit wet and dry?
