Guy at the hardware store asked me why I was buying 3 different types of caulk

I was at Lowe's grabbing stuff for a bathroom remodel and this old dude just walks up and asks what I'm sealing. Turns out I had latex, silicone, and hybrid all in my cart for one window trim job. He told me stick with one type per project or you'll get adhesion failures, and he was right about my last job cracking in 6 months. Any of you ever messed up by mixing caulk types?

Three different caulks in one cart sounds like my ex's skincare routine, messy and doomed to fail.

Man, I've been there. Mixing silicone caulk with acrylic latex in the same project is asking for a disaster. What you really want is to stick with one type for the whole job, and if you're doing a bathroom, get a 100% silicone that's mold resistant. Silicone won't paint over, but it's way better for wet areas. Acrylic latex is fine for baseboards and trim where it won't get soaked. Just pick one and go all in, don't try to blend them or use different ones on adjacent spots.

Three tubes for one window is wild, I did that once with paintable caulk on an old wooden doorframe and it peeled off in a month because I mixed in some silicone from another job. @drew690 is right about sticking to one type, learned that the hard way too.
