How it works

Most off-the-shelf sealers require an application every 6 months to a year. These types of sealers sit on top of the surface and wear off with use. Our method does not depend on a membrane, but instead utilizes surface tension that WILL NOT allow liquid to pass yet remains breathable. The molecules of our sealers are hundreds of times smaller than off-the-shelf stone products and penetrate much deeper into the pore structure, even dense natural stones like granite. Inside the pores our special sealing molecules bond permanently by chemical reactions, creating a substantial, deep oil and water-repellent barrier up to 1/4 inch. The deeper barrier, not only provides great surface stain protection, but also protection against more serious common types of damage cause by water ingress (penetration), including efflorescence, salt spalling, freeze-thaw spalling, and picture framing.

The seal it once solution

Sealing stone surfaces is all we do. The products and methods we use are the best in the industry providing our clients piece of mind that lasts a lifetime

Quick process

Sealing your surfaces with Northwest Seal is quick and easy. Our accredited applicators can treat your countertops in as little as one hour. Most other projects including driveways, showers, large floors and patios are typically completed in one day.

Retain natural color and finish

Many sealers can darken surfaces and can also add a sheen or gloss. Due to the chemical properties of our process, the application goes unnoticed. Want gloss? We have that covered too.

unmatched Performance

Because our sealing application penetrates up to 1/4 inch, it is virtually impossible to wear off. Our process out performs all other sealers and can withstand the most rigorous high traffic commercial use.

Food safe

Once cured, our treatment is inert and will not produce emissions making it safe for food contact.
