Wood Slab - Oil/Epoxy
Hi All, I have been doing a big slab , I have filled the holes with an clear epoxy and sanded it back and now am ready for a finish. I have read that if I use oil that the epoxy can 'Pop' out or detach from the wood as the oil gets in under it. I was thinking of using 'Glass Finish' from feastwatson, think I need to seal it first with 'Sealproof'. will this bring out the colours? I still have some bark on it and I think the epoxy glass finish will suit it well to hold it all in place and be scratch resistant. I would however like to use the Festool Oil burnish system but as it is Camphor.L the smell is very strong so maybe the epoxy will help seal that in too. any thoughs.
Regards Aaron

An oil finish doesn't cause the epoxy to pop, once it is bonded its bonded, poly resin is a different matter. Glass finish, or Envirotech etc are a very high build high gloss finish, hard wearing and will help bond things together. The oil gives a more natural appearance but need to watch water/heat stains. It therefore just comes down to your own personal taste

thanx, I will have to do a test piece and see what I like. I think he epoxy glass finish would be better on the desk top with bark have you used glass finish, I am concerned about the yellowing in the future as desk is under window, however the glass s 100% UV blocking. Could I oil and then glass finish?? thanks forth reply

Hi Aaron, I absolutely detest those high gloss finishes and think their use should be declared a criminal offense. They just look awful and artifcial and will show every scratch and imperfection.
If this is what you want then it is down to personal taste.
You are much better with a low sheen or semi gloss finish, I have used wipe on poly, oil finishes and becker Acroma and would recommend any of them.You shouldn't have any real issues with the resin infill you have used.

Hi,
If you want a great finish using an oil, you could try using this method. It's a hard burnishing method, but with less mess than either the Organoil or Festool burnishing methods..
The resultant finish is liquid and heat resistant and is very robust.(You clean it with Spray and Wipe!!)
Regards,
Rob

I have used epoxy to fill cracks and holes on pieces.
I then used oil, wipe on poly or shellac to finish pieces. None have popped the epoxy.

I haven't used the Glass Finish for a table, only the Envirotech that is similar, 17 years later with 3 kids growing up and still looks great (for a very shiny finish). It was a very hard finish on a very hard timber (100 year old Batu) and had only minimal scratches but were easily polished out. I wouldn't put it over an oil finish, but check the instructions.

If you want epoxy over an oil finish I would recommend either of two things. The first would be to use a drying oil such as tung oil, and let it fully cure 5+ weeks then apply the epoxy. The second way would be to seal the moderately cured oil (1 week curing) with an oil-based polyurethane, then go over it with the epoxy. Basically u just need to avoid applying epoxy to wet oil, also not sanding the panel above 240grit will leave some tooth for the epoxy to grab.
