That has been the case in the past. Seems our home builder used caulk to hide cheap lumber plus the caulk almost welded itself to the smooth faced brick. The multi function tool using a flat blade was recommend to me by a pro but was too expensive and would probably never be used again. Tried the most powerful paint stripper I have ever found. It did nothing. I used Liftoff brand caulk and foam softer, a painters tool, wire brush and very, very narrow and intense spray sream of water. Got most all off. I'm hopping the building contractor will do me a solid and remove te small amount left. Oh, I worked at first light for about 1 hour for four days.
