Pic Request: Epoxy over Baltic Birch

Postby gpr5027 » Wed Jun 17, 2020 3:11 pm

Howdy,

Does anyone have a photo of some baltic birch (raw, no stain) that was epoxied, ideally with Raka? Not looking for examples where poly was used before or after, or with glass, spar varnish, etc. Just plain two part epoxy.

I am specifically looking to understand what kind of finish I can expect epoxy to yield when used on baltic birch or an equivalent light wood, and whether or not it would be "interior grade" and pretty. All of the photos I've been able to find are generally at the end of the builders process and include a combination of products, not just epoxy - and perhaps that's for a reason that only I am unaware of - but as a total newcomer to the world of epoxy and painting in general, I feel the need to ask.

Thank you!

Check my build pictures closer to the end, I used Baltic birch plywood and epoxy on internal walls, entry and access doors. Links are in signature below.

The appearance of epoxy coating is close to oil based polyurethane over the Baltic birch plywood and it looks similar with glass cloth or without, because cloth becomes transparent with epoxy in it. Hope it helps.

I'll ditto that but add the word glossy.

Yes Tony, agreed, epoxy is 100 percent solids and provides gloss finish on Baltic birch after a second coat. First coat gets somewhat absorbed by plywood fiber, but once first coat has sealed the fiber then all second coat epoxy stays on top and provides a high built gloss finish. With oil based poly you'll need multiple coats to get close to that same point.

Thanks guys. BTW, really neat build OP827! The glossy finish is what I was fearing. I don't love glossy. However, I think I dislike the orangey-tone of poly even more. Does epoxy at least maintain the light (almost white) finish of raw baltic birch, and add a glossy finish to that, or does it become both glossy AND orange? I really want to maintain the light wood look and keep the finish as flat/matte as possible, but I'm not sure it's possible without leaving it bare..

Water based poly I think gives lightest white finish you can get. Epoxy penetrates wood and makes it darker then water based poly. I personally like epoxy finish, it does not look orange to me, it is rather warm color. You will have to test it or see others' builds. Note that all wood, that is clear coated will go darker with time. I have birch shelves from Ikea that were very light and after a few years they are pretty yellow now. Same with pine or other species.
Oh, as for gloss, you will have to coat epoxy with some clear coat anyways, so you can do it with non-gloss clear or to your taste.

This is three coats of satin oil-based Minwax poly. Epoxy will create the same color. You can always apply a satin poly over epoxy.

And as mentioned, water-based poly will leave the birch the same color it was. I prefer the oil-based stuff to bring out the grain and add a bit of color.

Here's a galley shot showing the epoxy floor and poly'd birch and alder.

That is an old wood finishing tip/trick. If you are looking for a satin finish, start with a clear gloss finish first and use a satin finish on the last coat.

You don't want to apply multiple coats of a satin finish. To get rid of the gloss, a satin finish contains solids to break up light transmission. Too many layers/coats of satin finish will result in a milky appearance.

Of course if you want to really go old school, apply just clear gloss finish. After curing, "sand" the surface with #0000 steel wool or use rubbing compound.

Here's a couple pictures during my build years ago. Baltic birch with just 3 coats of epoxy, before I put on multiple coats of varnish.

Our trailer is 11 years old. It is RAka with spar varnish over the top of baltic birch. With the epoxy only, it is glossy until you sand it for the final finish. Not sure why you don't want the final finish, as you need to cover the epoxy with the spar varnish to protect the expoy from sunlight. My finish has not has not changed color. Plus, also not wanting the super glossy finish, the spar varnish is satin, not high gloss. Check my album for photos. Please note, I have not uploaded any photos in the last five years, but it looks the same. We have refinished the varnish twice due to rain damage. It still looks like new.
