Pine sap coming through stain. - stoppy - 06-13-2021
Three years ago I made a small table out of 1x4 pine to set next to wife’s lawn chair for whatever she wanted to use it. She stained it the color she wanted. It sits outside in the summer and is stored indoors in the winter. I can scrape and sand the the sap away. How best can I keep it from coming back?

You may not be able to stop it completely. I've had good luck with shellac on preventing it, but shellac is a very poor outdoor finish. My choice in this case would probably be a good oil based primer, and then paint.

If it was air dried pine they say the sap never sets up. I have a wooden screen door on the garage that bleeds sap every year. Roly

Talked to the table's owner, she doesn't care about the sap only brought it up 'cuz son pointed it out, likes the color it is stained. Problem solved.

FWIW, yard grade ( C and D ) pine from a kiln is normally "resin set" as a final stage. Setting the pitch (woodweb.com) Oil-based finish shares a common solvent - turpentine - so it won't block seep.

Reminds me of that old saying: "If you want to be happy with my performance, lower your expectations."

If under a paint, rubbing caulk over the knot will seal the spot.
