Hi All - I have noticed these fine cracks coming up in my bath tub. These are mostly around the grip circles. While doesn’t seem like water may be going in through, however, one of the cracks is too big to ignore. Appreciate any suggestions to fix this issue.
Hi @newbie3,
It sounds like the cracks may be a result of delamination, possibly caused by the suction cups of a non-slip mat, as I experienced with a bath I re-coated a few years ago. Over time, wear and tear can weaken the coating, leading to cracks.
The most effective solution would be to remove the damaged coating entirely and reapply a new one. You can attempt this as a D.I.Y. project using a bathtub refinishing kit, but keep in mind that older tubs may have lead-based paint, so proceed with caution and ensure proper safety measures. Alternatively, seeking professional assistance could provide a more durable and high-quality finish. Regular cleaning and avoiding suction-cup mats in the future can also help prevent recurrence.
Please let me know if you have any questions.

Thanks Mitchell for a prompt response. Apologies I had not shared a zoomed in picture. Pls see one attached now. Do you still reckon it can be taken care of by only the refinishing kit? No epoxy needed?
We haven’t used any bathmats in the last 5 years. Perhaps there are built in protusions on the floor of the tub for grip. What do you think?
many thanks again for your time.
The tub coating product is a two-part epoxy @newbie3. However, you'd likely need to remove the existing damaged coating on the bath. You could try coating over it, but I am unsure as to the longevity.
What is the tube made from? Be advised these recoating products are not suitable for acrylic tubs as they flex too much.
Mitchell
Thanks Mitchell!
I am not quite sure what material is the tub made up of. Here are some more pics for reference.
Is there an easy/ reliable way to check?
Nonetheless, the product you recommended - if that is epoxy based then it should be good for taking care of the minor cracks without needed for them to be filled in. Is that understanding correct?
many thanks again with your patience.
Check to see if the base or side walls flex at all when you push them @newbie3. If they do move, then it's likely acrylic. If it is then I'd suggest enlisting the services of a professional for re-coating.

I'm sorry @newbie3. I was fairly convinced you couldn't use this product on acrylic, but apparently you can, and on fibreglass, too. Ideal for ceramic, porcelain, fiberglass, acrylic, cast iron, and steel surfaces.
Mitchell
It does say in the preparation instructions that cracks should be filled with a patching compound @newbie3. However, given that your cracks are hairline, I don't think you'd be able to fill them. A good sanding of the surface and coat over the top should cover them, but I can't guarantee they won't return in the future.
