Is this caulk not intended for use around the tub

bathroomcaulktub

I am recaulking around the edge of the bathtub where the tub meets the tile on the wall. I got caulk listed as "for kitchen & bath": Loctite PL(Pro Line) 530. I haven't used the shower in weeks and finished cleaning the old caulk off. Reading the directions on the caulk, two things concern me: "Not Recommended For: …, tub surrounds,…" and "Do not use in areas subject to water immersion".

I am hoping the first means it isn't meant to structurally hold a tub surround(like one of those molded wall liners). Maybe the second is saying it's not meant to seal things that would be subject to water pressure, i.e. sealing something that holds water and thus would need to structurally hold under water pressure.

So is this caulk not intended for use around my tub?

Best Answer

PL 530 is not on Loctite's website

Are you sure that the number is correct?

Given their products with similar numbers, your tube of 530 is likely an adhesive, not a sealant. I would not use it except as a last resort in an emergency. I'd use a tube of sealant instead.
