Im building a table for a client who brought me some wood off of the home they are remodeling build originally in the 1850's . It's yellow pine or heart pine and it's been a royal pain in the tushy. every step has been a challenge now that I'm into the finishing phase and I am struggling mightily. I used Watco danish oil for the stain and applied three to four coats not realizing after two I was just adding varnish basically. it sit for about a week and I get ready to apply Polycrylic for the topcoat. I apply about five layers allowing each coat to set up and lightly sand with the synthetic sanding pads and sand lightly between each, I have used a HVlP to apply the finish. the weekend of delivery I notice something that was puzzling so I go to fix it and notice the side was peeling I try to sand but it turned to goo now full on panic has set in and I notice the top is lifting . I could pull the clear off by hand. I then use a stripper and remove the top coat all of it. I try to re sand but it seems to stay gooy the wood that is. i was looking for advise and reached out and was recommended to use shellac I did two coats probably should have read more then the can before applying as it didn't set up either it stayed sticky in some places. I begin to sand it down and it is just gumming up as I sand I waited for five days to start to sand , Now i'm totally lost on what to do it's to be delivered and I can't get the top finished it is staying oily. Has anyone every had this problem where the wood was damaged in some way and took on a lot of oil and wont dry. any Ideas other than a stick of dynamite would be helpful. I've started to re sand the whole top but some places it just seems to be oily.
I am going to sand and reapply oil and then spray with spar urethane or oil poly . this is a brute of a table as well it's 12ft by 4 ft and has a matching old church pew that I've redone to match it is fine but this table has me losing my salvation. okay let the info commence.
