Recent (built 2003 – 2006) log and timber A-framed home in UT at elev. around 5 k ft. Siding is pine tounge and groove stained a sunset redwood color. Problem 1: The stain on siding is patchy, and blotchy in some areas. Needs to be re-stained, however the South siding and some on the East is seeping sap. How do I remove the sap to re-stain? Will I have to do this to the entire pine tounge and groove siding of the house? Problem 2: Interior A frame beams also seeping sap in some areas. Do
The wood wash too green when it was applied. That is what is causing the seeping. It may continue for several years, but may be less since it is half log. You can use a heat gun and a putty knife to scrap it off or corn cob blast the entire house to clean it up (which I would recommend). The beam inside is weeping due to heat in the winter more than likely. We once cleaned a house by heat gun and scraping, and by the time we worked our way around the house the knots where already seeping again.
