Questions & Answers

My handyman used this for my kitchen sink. I see it’s not approved for that use can it be removed and redone?

Asked by: Kp
I would not remove it. It's a superior caulk to most. Stays flexible, stretches with movement of materials. It's mildew resistant. I recommend leaving it there. It was a good choice based on my long experience with this specific 230 product.

Will this caulk bond to Hardie fiber cement at the ends where it meet the wood
Asked by: truckin
Yes, but it's not advisable. Over time it will harden, crack. Use an elastomeric seant. Or at the very least a silicone.
