Applying caulk strips to a curved inside corner - help!

July 13, 2023 8:23 AM

I’m using Insta Trim to caulk my bathtub. (I know this fails various homeowner purity tests and don’t feel like being reprimanded for it - there’s a specific and good reason.) I have a tub surround with curved corners. Is there a strategy?

Google is failing me hard at this question - all I’m getting is breathless ads encouraging me to buy some Insta Trim, which I obviously already did. So can someone who knows please share some thoughts on sticking this stuff in a CURVED inside corner? Thank you!

I feel like you'll have to cut triangles out of it with a razor knife. If it's a spot where it's just cosmetic, that might be fine, but it will do a worse job sealing against water. What is the specific and good reason to use this product there? Maybe someone can help think of a better solution if you elaborate.

Best answer: Hair dryer. It's on their 'how to apply' page.

I hate caulk, this might be useful, thanks.
