Topic tags/keywords: redwood color epoxy discoloration wood question resource help ecopoxy tip knowledge

Hey guys,
New woodworker here. I found an old slab of what seems to be curly redwood that used to be part of an old grandfather clock that i salvaged from a junkyard. I cut it up and turned it into an epoxy table. After applying the resin, the bottom portion of the table which is covered by ecopoxy resin seems to have these brighter red discolored drips that seem to be coming from the small black knots in the wood. Its so beautiful and i want to recreate it with the too side since i dont have any more of this redwood to work with. But im not sure whats causing it because on the top where i just apply valspar, this discoloration is not appearing. My guesses are

1. The ecopoxy reacted with the wood and brings out more of the natural color then the valspar does.

2. Since it is on the bottom of the slab, when i wash the top off after sanding, the water that is soaked into the red wood drips out of the small black knots on the bottom and creates these red “drip marks”. The drip marks are a bright red due to being soaked through the board.

3. This is just how redwood looks and im an total noobie.

Please help!!

Why are you washing the wood with water after sanding the surface? The pictures are hard to figure out what is going on.

First, the wood appears to be a redwood burl. The red color may be natural dyes in the wood or could have been applied for its previous use. It would be very risky to try to duplicate the color on the top without knowing the cause of the color on the bottom.

Im washing the top off because since it is a river table, when i sand the whole surface epoxy powder flies everywhere and washing it is easier for me to get an idea of how level it is (eg laying a level on the surface and seeing how flat it lays on it) and also how the grain is turning out(if any burly curlys are being exposed). Mind you i am only working with a hand saw and an orbital sander because i am a poor college student.

The pictures are just the bottom surface of the table that the epoxy seeped under and covered. If you look closely you can see the red discoloration juxtaposed to the wood. Here are some pictures of the top of the project.

@phil32 thanks for the reply! It could very well be natural colors coming out. It might be previously dyed wood, but i think the chance of it being natural is a bit higher because i sanded both sides down quite a bit before filling with epoxy
