Needing a little advice on the best way to remove construction adhesive from pine. I have a job that involves removing pine 1x trim on a wooden garage door, and replacing it with a wider piece of trim. The existing trim is glued to pine v-groove. I have already removed the trim and there is still construction adhesive adhered to the v-groove. I need a flat surface to glue the new trim to the door.
One possible way I was thinking was to use a heat gun to soften the adhesive and scrape it off. But would a heat gun burn or damage the pine underneath? I want to avoid using solvents, sounds messy and the door will have a stain finish applied. Pretty sure solvents would mess up the stain application. Any suggestions?
