firs – thank you for having an open forum so i can post. I am not a woodworker – i am a diy homeowner with a problem that i cannot find an answer to. i have been asking and reading for several months now and mostly what i get is ‘i don’t know’ or sand off and start over. when i found this site, i thought all of your experiences might have an answer for my problem.
i live in southern arizona and last year this time we had a new patio cover built. the contractor used 4×4 pine posts for the posts on the patio and attached porch. We painted them with behr outdoor paint that contained primer. My problem? – the boards have leaked sap through the paint and not a little bit either. Any ideas of 1) how i would clean up this sap 2) how i would prevent this from happening again 3) anything else pertaining to this. :)
thank you in advance for allowing me to crash your site and use your talents to my advantage. – mrsfish

I have a log home and from time to time find a spot where the sap has managed to break free and seep out of the log. I usually wipe it off with some denatured alcohol. As for controlling it I don’t have an answer for that. Given that wood is always moving I really don’t know if it possible. Hopefully someone has a better answer for you.

I have even had to sand down a floor board or two (12” wide pine) because the board leaked sap and complete deteriorated the finish (turned it into what felt like sticky glue). That is with 6 coats of Varithane.

Mrsfish I had a similar problem with my front entry doors. They are made out of pine and here is a picture of one side:

The front of the house faces west and, with the glass storm doors, these doors get extremely hot when the sun shines on the front of the house. After a couple of years the heat baked the sap out of the doors and the doors had several areas where the sap pooled and ran. After looking at this for few years (and getting “encouraged” by my wife to fix the “eyesore”) I refinished the doors about 10 years ago and have not had the problem reoccur.

Basically I don’t know of any other remedy except time to solve your problem. You may have to scrape off the sap residue and repaint them fairly often at first but, over time, the sap residue should diminish as the lumber weathers.

Hope this helps.
