## Description

Product description Stops leaks fast. Starts out as a thick liquid and dries to a super strong, flexible, watertight, rubberized coating. Seeps into cracks and holes. Blocks out air, water, and moisture for a superior seal, virtually anywhere. Prevents rust and corrosion. Extends the life of patio furniture, pool pumps, RV and shed roofs, and more. Stands up to extreme weather changes. Expands, contracts, flexes and stretches. Resists rain, snow, sun, and hail. Exceptional adhesion. Works on all types of surfaces, even challenging ones, like metal and glass. UV and chemical resistant. Use indoors and outdoors for basement waterproofing, foundation fixes, roof repairs, and more. DIRECTIONS Fully clean and dry the surface for best results. Etch the surface to help with adhesion if needed. For the best application, use a standard disposable paint roller or paint brush. Apply several even, thin coats and wait 24 - 48 hours for each layer to fully dry before adding the next. Always place the lid back on the container after each use. If drying occurs, remove any skin before using product.

Review: Sturdy, resilient, reliable - Amazing product, I've been using so many other brand names for roof sealant, and this was the only product that allowed me to fully fix my roofs leak-free. It's been almost a year and it's still very study and waterproof. All type of weather here, storms, hurricanes, snow, heat from direct sunlight, etc, and this product still keeps the roof nice and clean.
Review: It works for me - So I bought this for my rv leak. I have an older rv model from the 80s it has a tin roof. So i bought two buckets of this for my 27 foot rv. I will state that it only took one bucket. I will state that I put 3 layers of this paint on my rv roof and sealed it up just fine. The suggestion I will make is dont use a paint tray with it. as the paint will stick to it and youll never get the tray back once it does lol. I suggest you use a paint tray insert instead. Also i suggest you buy a larger paint roller. it will save you time. also youll need multiple layers on the roof and each layer needs to dry. those rollers will dry fast. so expect to buy at least 3 of them. I suggest getting small brushes for detailed work or nooks and crannies. All in all youll be looking at roughly 600 bucks invested in a rv roof sealing project of my sized rv.

## Questions & Answers

**Q: What is the difference between the MAX and the regular?**
A: The max is a slightly different white color. Different color than spray too. Which ever you choose stick with one or you will have multiple shades of white.

**Q: What's the best roller nap quarter inch or three eights to apply this with**
A: Product is super thick compared to regular paint. Shortest to no nap the best. Takes practice to get used to products viscosity. Try to apply thick and in one coat for best results. Product will self level as well and can also apply with trowel.

**Q: Will this work on a fiberglass swimming pool ?**
A: I'm not sure how long it will last because it is not reccomended for underfoot applications

**Q: Will this work to waterproof bottom of window sills?**
A: Yes. This will work well

### ⭐⭐⭐⭐⭐ Great stuff!
*by J***N on October 30, 2024*

Used on several roof tops on RVs, flex is a cost effective alternative to very costly repairs. Was quoted over 5k to replace the roof and only options for colors were tan, grey, or black, and; well it doesn't take a genius to understand that those colors tend to absorb the sun and cause for breakdown of the material. If I was to spend 5k I would want the material white. Didn't have 5k or consider it anymore after the color options offered. This pail was not bad priced and one did two coats on my cleaned roof, 37ft long 8ft wide. I have noticed it not as hot in my trailer and ac kicks on about 3x less than before. Very happy with how it turned out and will plan on doing another pail just for peace of mind.
