Okay, it's epoxy-pouring time...

And I have another question for you woodworkers.

I have this slab of redwood with some cracks, several of which are quite deep, but don't go through.

I have a slow setting epoxy.

QUESTION: Is there a risk that the epoxy will soak through the soft redwood and come out the other side? This would be disastrous as it would stain the wood and I would not be able to sand it out.

Do I need to seal the deep cracks with a thin coat of fast-setting epoxy before doing a deep, slow-setting pour? And if so, how? Should I brush it in?

Thanks!

Do you mean soak through the solid wood itself, not an existing hairline crack going through to the other side? I highly doubt it. I've poured a couple redwood pieces and only had seepage through the existing cracks, which masking tape helps corral.

I do know that some people will brush on a thin coat first to help with any potential soaking. If you are concerned about #1 that could be a good failsafe.

seal the wood with a fast setting epoxy before pouring your slow set so it doesn't seep into the grain

That's my plan. Thanks!
