Mixing finishes can be such a headache, I totally get it. Testing with alcohol or thinner is smart—wish I’d known that before I tried sanding through three mystery layers in my hallway. Ever run into finishes that just don’t react at all? That’s always a puzzle. I do like water-based poly for the price and ease, but you’re right, it’s just not the same look. For trim, I’m always torn—do you ever just leave old shellac as-is if it’s not too beat up? Sometimes I wonder if I’m overthinking it...
Leaving old shellac can be a toss-up for me. I’ve run into trim where the shellac was still holding up after decades, just a bit dull or scratched in spots. In those cases, I usually just clean it and maybe hit it with a little fresh shellac or wax—saves a load of time and honestly, that patina is hard to fake. But if it’s flaking or sticky, I bite the bullet and strip it. Sometimes I think we all overthink this stuff... half the charm is in the imperfections anyway.
Funny you mention the patina—my partner always wants everything to look “like new,” but I’m with you, there’s something about those little nicks and wear marks that just feels right in an old house. I’ve had luck just cleaning up old shellac and letting it be, but sometimes I wonder if I’m being lazy or just appreciating the history. Ever tried using a tinted wax to even out scratches? I’ve had mixed results, but it can blend things in without losing that old vibe.
I totally get the “like new” vs. lived-in debate—my partner’s the same way, wants everything shiny and perfect. For the scratches, I actually tried a tinted wax stick on our old banister last month. Here’s what worked for me: rub the wax in, buff gently, and then leave it alone for a day or two. It sort of settles in and looks more natural over time. Sometimes it does make spots look a bit darker, though... I guess it’s all about finding that balance between tidy and authentic. Honestly, just cleaning up and letting the old finishes breathe seems less stressful than chasing perfection everywhere.
