First post, so I apologize if this is not the best spot to ask this question. I have put up a 9 ft high by 8 ft wide wall of what was advertised to be fairly clear of knots, ship-lapped white pine. The boxes sat in my entry for a few weeks and were well acclimated to their future environment. I boards have been on the wall for about 3 weeks now and just the other day I noticed that one of the small knots was beginning to ooze sap. Not much but enough that it is slightly sticky and enough for me to notice. My question is now that the wall is in place, what is the best method for me to deal with the current sap and is there a treatment for other areas that I notice may be getting ready to ooze? I read somewhere to clean the existing sap with oil soap. Also I was planning on staining the wall, not painting. I have attached a picture of the wall.

Thanks in advance for any help. Have a blessed day.

Carroll N.!

I don’t know if I have a right answer but what I would do is clean up the sap with acetone and paint the knot with shellac.

Staining pine is something I usually avoid these days but if you do I would recommend an oil stain because a water stain could cause some wood movement since it will only be on one side.
