Tenax Proseal is one of the industry leading sealers for use on marble, granite, engineered stone, quartzite and grout. Tenax Proseal penetrates deep into the stone surface to leave a ultra premium seal with not stains or residue.

Tenax Proseal Ultra Premium Stone impregnating sealer is rated by fabricators as one of the best granite, marble, stone sealers to be used on natural stone. Period.

No other sealer will penetrate and protect as well as Proseal.

What about the 15 year sealers? Or sealers that come with a warranty? Are they better than Proseal?

Logic would think so. But the reality is they do not! Tenax Proseal Ultra Premium Stone Sealer out performs these sealers over and over again. In every instance that Proseal Granite and Marble Sealer has been tested directly against these sealers, the proseal is the one that does not leave the stain.

Don't just take the Tenax word. Look at the below video from an independent company made to compare Proseal against Dry Treat, Stone Tech, and Miracle Sealants 511. All of these sealers are very well known and 2 of them offer warranties.
What was the result?
ONLY Proseal did not leave the stain.

Why doesn't Tenax offer a warranty with Proseal Ultra Premium Stone Sealer if it is better than the warranty stone sealers on the market?

Read the fine print of the sealers and you will see exactly what is covered, all the hoops a fabricator has to jump through to even attempt to get a warranty (one even asks to send them a piece of the countertop to them so they can determine it was their sealer), only to find that the warranty companies will send you a free bottle of sealer.

Tenax would much rather offer the best sealer that chemists can make at a very affordable price, have a fabricator seal the granite, marble, stone counter top, and allow the home owner to not worry about stains. Tenax prefers the old keep it simple method.

Tenax Proseal is suitable to protect granite against practically all potential kitchen stain causing items: coffee, wine, oil, peanut butter, mustard, ketchup, soda, etc.

Proseal impregnating sealer also works well with polished, honed, brushed, matte, finishes.

What about high porosity materials such as marble, travertine, limestone? Tenax Proseal fills the pores ans seals these very porous stones and protects the stone from oil and water stains better than any other Porous stone sealer.

Can Proseal be used for sealing grout?

Absolutely! After using Proseal for sealing grout, test it by putting any liquid on the grout. it will bead up like you just waxed your car!

Outstanding for Indoor and outdoor applications, Proseal is recommended for stone that will be exposed to wet conditions such as showers, patios, outside bars, pool copings, pavers, etc.

Tenax Proseal does not change the natural colors of the stone and allows the stone to breathe without leaving a film on the surface.

Wait 24 hours to allow the stone to dry and reach 100% protection.

The protection will last up to 4-5 years if the product is applied correctly on the surface and areas that are not under direct wear and use.

Tenax Proseal Stone Sealer Motto: Seal it and forget it!

if you want to install a kitchen and not worry about stain call backs, Tenas Proseal is the sealer for you!

DIRECTIONS: This product must be evenly applied on a completely clean and dry surface. Spread Tenax Proseal evenly with brush, sponge,cloth or spray gun until surface no longer absorbs product. After a few seconds buff with a clean cloth. Any excess of Tenax Proseal creates superficial glossy and sticky films so any excess must be removed immediately after the application. Repeat after 10-15 minutes. Do not walk on floor for 24 hours.

IMPORTANT: When using Tenax Proseal for the first time we suggest testing on a small hidden area first.

One liter of Proseal treats approximately 215-323 sq. ft depending on the porosity of the stone.

WARNING: Tenax Proseal does not provide anti-etch protection on marble surfaces. Use of acidic substances such as wine, tomatoes, citrus, coffee, etc. will etch the surface by creating a chemical reaction with eh calcium carbonate present in marbles. For etching problems use Tenax TeEtch
