Worked for Me
The reason I needed this- besides looking a bit unfinished- there was a slight draft between the joint of my wall boards and the Beam - it’s an old house so the insulation may be under par so I do the best I can filling the gaps so to speak. Anyway I wish the color was a little darker but the caulk did its job (I might try a little paint since you can paint it- or maybe not decide tomorrow) - I took a couple pictures before and alter and despite a slightly sloppy caulking job on my part but it looks much better- the good news it’s a bit up there so no one is going to notice the sloppy job but me. I must admit I lean towards DAP on all my chalk - is it the best ? Not sure but I am never disappointed and the cost is good, so I stick with what works!
