Patios take a beating: BBQ grease, spilled drinks, leaves, rain and freeze-thaw cycles. Topical patio sealers form a film that traps moisture and peels under UV. Nanoprotect penetrates into the concrete or stone, bonding inside the surface so your patio repels water and resists stains for years — with a natural, non-glossy finish.
A quality patio sealer protects your outdoor surface from water damage, staining, algae growth and freeze-thaw cracking. Nanoprotect is a deep-penetrating patio sealer that works on concrete patios, cement patios, stone patios, patio pavers and natural stone — sealing from within rather than coating the surface. No wet look, no glossy finish, no film to peel. Just invisible protection that lasts 36+ months.
Concrete and cement are often used interchangeably when talking about patio sealers. Technically, cement is an ingredient in concrete — but in terms of sealing, the same penetrating formula works on both. Nanoprotect's stone impregnation formula penetrates the pore structure of both concrete and cement patios equally effectively.
For patio pavers specifically — brick pavers, concrete pavers, natural stone pavers — a penetrating paver sealer is the best choice. It stops water infiltration between the pavers, prevents algae from growing in the joints and keeps the sand joints stable. Nanoprotect works on all paver types without changing their natural appearance.

"Applied this last spring on my 800 sq ft driveway. A year and a half in, water still beads up like day one. No flaking, no peeling, no color change. Wish I'd found this years ago instead of resealing every season."
Mike R. · Phoenix, AZ · Driveway
"Tried two other 'top-rated' sealers before this. Both turned cloudy and started peeling within a year. Nanoprotect soaked right in, didn't change the look at all, and the BBQ grease stain test is night and day."
Jennifer L. · Charlotte, NC · Patio Pavers
"Worried about freeze-thaw damage on my new concrete patio. Sealed it in October, made it through a Denver winter with zero spalling or hairline cracks where I treated it. Easy to apply with a pump sprayer too."
David K. · Denver, CO · Concrete Patio
"Our travertine pool deck would get those black algae spots every few months. Sealed it back in spring — six months later it still looks clean. Pet-safe was a big deal for us with two dogs."
