- 100% Breathable - Doesn't Form...
- Water-Based - Soap & Water...
- 5 Year Warranty on Vertical...
- This water repellent is totally clear and provides a long-lasting non-glossy coat to concrete, masonry, and stone surfaces.
- It protects stone surfaces from pitting or cracking caused by de-icing salts.
- Simply spray the sealer onto a clean surface with a low-pressure pump-up garden sprayer for excellent protection of exterior brick, concrete, and stone surfaces.
- It comes in different container sizes (1 gallon and 2.5 gallons).
- You will get a 5-year warranty on masonry and vertical concrete surfaces.
- Moderate coverage (90-150 square feet per gallon)
- Not recommended for stamped concrete.
- Thin and runny.
Water stains on your brick, concrete, or stone can make it look old and worn.
The problem with many stone sealers is that they use silicone to create a waterproof barrier.
Silicone forms a hard film and traps moisture which causes pitting, cracking, and delaminating of the surface underneath.
This creates even more work for you down the road when you have to re-seal again in order to protect your masonry from water damage.
Masonry Defender uses an advanced polymer technology that allows trapped moisture to escape while also repelling water without forming any kind of film on the surface.
Their products are soap & water clean-up so there’s no residue left behind once it dries!
They are also eco-friendly since they’re made with plant-based materials instead of harsh chemicals like most stone sealers out there today!
Concrete, brick, and stone are porous materials that absorb water.
When those pores fill with water, they can freeze and thaw repeatedly which causes the surface to crack or spall.
This is called freeze/thaw damage. It’s common in areas where temperatures fluctuate a lot during the winter months (e.g., Northern U.S.)
The best way to prevent this from happening is to waterproof your masonry surfaces before it happens so that water doesn’t get inside of them in the first place!
Unfortunately, most concrete and stone sealers don’t provide 100% waterproof protection against freezing rain or snowmelt because they form a thin film on top of the surface instead of penetrating into all of its pores (like Masonry Defender product does).
They also have a strong odor that makes using them difficult for homeowners who want their outdoor spaces to smell nice again after applying them!
That’s why we recommended all Purpose Concrete, Brick & Stone Sealers by MasonryDefender as the best sealer for natural stone tile so you don’t have to worry about your stone tiles/stone surfaces.

Natural stone and tile surfaces can be expensive to replace.
Maintaining your natural stone and tile is just as important as the initial installation.
Without proper maintenance, grout lines become dirty, dull-looking, absorb stains and discolor.
Over time, dirt particles are trapped in the pores of the surface causing etching that makes cleaning more difficult.
To restore these surfaces to their original beauty you have two options; professional polishing or sealing with a penetrating sealer like UltraCare Penetrating SB Stone & Tile Sealer.
Protecting your investment by using a penetrating sealer will extend the life of your natural stone floor or countertop without compromising its appearance or shine because it seals both sides of grout lines at once leaving them clean and stain-free for years to come!
When the grout is dirty or stained, it can make a room look dingy and dated.

Some will seal but not last long, some will last longer but not seal as well.
