I would like to cover the holes in some plastic flower pots. Would this be a good product to use for my project?

Hi there, thanks for the awesome question! The Flex Paste adheres to most surfaces, however, it may not adhere to certain plasticized surfaces. For this repair, we would recommend to use the Flex Seal Liquid instead. For the best results, we recommend to fully clean and dry the area before applying the product. If you have any other questions or need help with your repair, feel free to message us at Humans@FlexSealProducts.com. Take care and Flex On!
