Review: Not got what paid for - One coat…..very very little affect, almost undetectable
Review: Product used in non recommended situation. - I wanted to use this on the bottom of a litter box, it was plastic. This product is designed to be used on wood products,maybe concrete. It must be something porous. I poured three coats into the litter box but it failed in usage,my fault I thought that as long as the area was covered it would be ok. Not so.

## Features

- COMPLETELY INVISIBLE FINISH. Ultimate Sealant is a water-based penetrative coating for porous substrates such as concrete, clay, limestone, sandstone, flagstone, cantera, masonry, etc. that does not alter the appearance or texture of treated substrates.
- SIO2 NANO-BASED COMPOSITION. Instead of using conventional silanes/ siloxanes, Ultimate Sealant uses silicon dioxide nano particles that are able to bond with the substrate on a molecular level and offer longer-lasting UV ray and water repellent protection.
- EASY-TO-APPLY. Forget about applying a milky white looking liquid on your vertical/ horizontal surfaces that might end up leaving residues once it dries. Ultimate Sealant is odorless, colorless and can be sprayed, rolled, or brushed into almost every absorbent substrate.
- GREAT AREA COVERAGE. Each gallon can cover up to 450 sq. ft. on the first coat and even more on the second coat. It usually takes two coats for the substrate to develop an outstanding water repellent protection.
- LONG LASTING PROTECTION. Ultimate Sealant will offer a water repellent protection for more than 8 years on vertical surfaces. Due to the nature of its chemical composition, UV rays will not degrade it the way it degrades silanes and siloxanes, making it more resistant and longer-lasting than conventional sealers.

## Questions & Answers

**Q: does this product prevent salt on travertine pool deck**
A: Hello! Ultimate Sealant is salt water resistant, therefore, it will help prevent stains.

**Q: Will this product dissipate effervescence (chalky appearance) from old brick?**
A: Hi, thank you for reaching out to us. This product will not remove or clean any existing effervescence/ efflorescence from old brick but it will prevent this from forming in the future. You will first have to remove this from your brick surface and apply Ultimate Sealant only after it is clean and dry. Once your brick surface is treated with Ultimate Sealant, it will not allow the absorption of moisture or chalk residues, creating a stain-free surface.

**Q: Travertine pool deck ? Is it ok for that ?**
A: It should perfectly work. Follow directions on the label for prep work.

**Q: Will this product, if applied to wood, harden that wood?**
A: It will slightly harden it but it will not be noticeable to the touch. If you're looking for a product that enhances the color of wood and creates a rock hard protective layer, you might want to check out our industrial-grade, clear coating for wood: Lacquepoxy.
