This Flex Seal Flex Paste is a super thick rubberized paste that you can spread, shape, form and seal virtually everything. It starts out as a thick paste and dries to a strong, flexible, waterproof barrier that can be applied to all types of surfaces to seal out air, water and moisture. It clings to the surface and instantly fills large gaps, cracks and holes. It won’t shrink or wash away and can be painted any colour. It can be applied on dry or wet surfaces, even underwater.

It could be great for some situations but I wanted it to seal the wood along a window frame. It set too fast for me to smooth it and it can’t be sanded once set.

A: Hey there, Harv! We don't recommend Flex Paste for this, but Flex Glue can help! Many customers have used it for this kind of repair. Since shoes can be made out of a whole variety of materials, we recommend testing a small area out first. For best results: Make sure the surface is clean Apply firm pressure for a minimum of 10-30 seconds Allow glue to cure for 24 hours If you need anything else or have additional questions, send us an email to Humans@FlexSealProducts.com. We're always here to help!
