Hello, posting a picture of your problem might best give us an idea to suggest the most suitable suggestion. It’s possible your question is cut off.

But I can say -Ive repaired so many things with the Oatey epoxy putty stick!

I’ve done repairs on my cement planters and statutes with it.

I find it easier to work with than bondo and this clay like putty can be sculpted. It does harden in a few minutes and will dry gray needing painting.

It's a two-part epoxy sticky-found at big box hardware stores for about $6.

You mix press -then you can use scrape off excess (I use depleted gift card) and/or sand and paint. Cured putty is strong enough to drill through. Its a light grey putty.

Oatey Putty safely seals/waterproofs for plumbing boat repairs.... Ive used it for exterior entry door frame wood rot repair, elliptical pedal repair, multiple arts and crafts repair of furniture, pottery- wood -ceramic- concrete statues - even a garage laundry sink with a hole ( thanks for hiding that defect with carrots -previous homeowner)

Every home owner crafter or second hand shopper need a 2 part putty epoxy stick!

You can find other expensive and smaller 2 part epoxy sticks versions in the boat marine and wood repair sections this Oatey one is a great value.

Consider the epoxy putty for your repair needs.
