I stick to SW Multipurpose or Premium Wall and Wood for nw drywall primer.Any reco's on primer over bare drywall for the future? Any other tips to avoid this problem? Is it worth it to do a quick scrub with a TSP solution, or is that overkill?
As for scrubbing walls with TSP as a routine prep I am not sure, we sand all walls before painting as routine, not sure I want to wash them too, unless the need is obvious.
The reality is how often do you run into it, 1 in 20 rooms?, 1 in 30? So i have taken the attitude that I fix it when i encounter it, and move on. I use the 3M patch and primer in one for these small repairs, but it’s a bugger to sand and still needs primed.
