Caulk Stair Trim
Mike Flannery is in Denver, CO.
But he's perplexed about caulking the trim in a staircase.
Here's his full report, albeit abbreviated:
"Crack between moulding and top of stair risers indoors. Original caulk cracked. Looked sloppy. Removed caulk. 1/8 in gap. Idea is to put spline in gap as backing prior to re-caulk and then painting. But I don't know. How would u approach?"
Here's my wordy answer:
Mike, an eighth-inch gap is really nothing. There's no need for a backer rod.
The key is to use a high-priced caulk that has very little shrinkage. DAP makes a good one.
