I have another question about a banister I posted about in Sept.
https://www.hometalk.com/31469927/q-i-had-my-banister-painted-in-feb-but-about-two-months-later I'm finally getting ready to make the paint repairs to the banister. I'm actually to the point of applying the primer to the railing. I'm only going to paint the railing and the knobs. Problem is that the primer isn't very thick and I want an easy way to make sure it doesn't run or drip onto anything under it. All I can think of is to attach newspaper or plastic or something with Frog Tape that would be taped at the top of the balusters and extend to the treads so if any primer drips, it won't get on parts I'm going to paint. Is there an easier way? The primer is Zinsser B-I-N Ultimate Stain Blocker and is gray.
