## Questions & Answers

**Q: Will it stick to outdoor wood and is it paintable?**
A: I believe it would stick to wood outdoors.  I can't verify that it can be painted as I've never tried to paint it.

**Q: Would this work on an exterior chimney crown?**
A: It worked on a brick in my kitchen so yes it would however you might want to try the Paste version as opposed to the spray. 
The stuff is wonderful. No house should be without it.

**Q: Will this product break down the composition of styrofoam?**
A: Hey there. We don't recommend using Flex Seal Spray on a styrofoam surface as the spray will cause the styrofoam to melt when it comes in contact with the spray.

**Q: Does come with texture?  I want to use it the floor of a motorcycle trailer**
A: It has no texture.

## Customer Reviews

### ⭐⭐⭐⭐⭐ goes on nice and dries pretty fast, and is paintable if you need to later on
*by J***. on September 4, 2025*

using this for around my bulkhead once per year. keeps the dripping out. Also works good on foundation and steps. No more painting. A can goes a long ways. A little pricey now but what the hell isn't with the tariffs now.Have to order the gray color on Amazon. Can't find it in any stores, only the black and white. Probably sells out fast when they stock it. A very nice light gray color.

### ⭐⭐⭐⭐⭐ Great Stuff!
*by C***N on August 29, 2025*

Works well and truly seals to repel water.

### ⭐⭐⭐⭐ Okay but over priced
*by L***S on September 1, 2025*

Definitely needs to be heavily ventilated while using. Works well so far.
