When finishing a larger surface, like a dining table top, I've been having issues with Arm R Seal setting up too quickly. What happens is the section that I start with begins setting up, and when I move along, the edge doesn't remain wet enough to blend in with the edge of the next section if that makes sense. Even moving briskly, I cannot achieve a seamless flow from one section to the next. I have tried cutting the Arm R Seal with some mineral spirits, maybe 10%, but this has not helped.
I don't recall having this problem with Arm R Seal before, but it's definitely happening to me now.
Any suggestions?
