Nanoman Stone + Brick is a clear, breathable penetrating sealer for stone, brick, concrete and terracotta. It keeps water and water-borne stains out of the pores without changing how the surface looks.

Stain resistant
Long lasting
BreathableKey benefits
Supplied as a concentrateDiluted on site, so you ship and store less.
It soaks in and lines the pores with water-repelling groups instead of forming a film. Rain beads off, dirt and salts rinse away, and the stone still breathes, so damp is not trapped behind it. It is a PFAS-free, water-based nanocoating.
Film sealers such as varnishes, acrylics and wet-look coatings sit on top instead. They change how the stone looks, trap moisture underneath, and wear, peel or yellow in sun and foot traffic.

Independent lab test
A sample treated with Stone + Brick was fully immersed in water for 24 hours at 24 °C, then weighed. It took up just 2.96% of its weight in water: the coating keeps water out even when the surface is completely submerged, while still letting the stone breathe.
Water absorption to ASTM D570, 24 °C / 24 h. Tested by an independent NABL-accredited laboratory in Pune. Results apply to the sample tested.

Where to use it
Sandstone, limestone, travertine, granite, honed marble
Soft, open stones absorb the most and stain fastest, so they gain the most. Dense granite and honed marble take less: apply less and wipe off surplus within 10–15 minutes. Polished marble is usually too dense; test first.
Exposed brick, jaali, terracotta and quarry tiles
Brick soaks up monsoon rain, then pushes salts out as it dries: the white bloom called efflorescence. A breathable sealer lets less water in, so less salt reaches the face. Clean the bloom off and let the wall dry fully first, or you seal the problem in.
Driveways, compound walls, parapets, blocks
Keeps surfaces from darkening, staining and growing moss. New concrete must cure for 28 days first.
Water beads on the surface instead of soaking in, on natural stone and fired clay alike.
Algae, moss and green growth
Green and black growth has to be killed inside the pores, not just scrubbed off the face, or it comes back under the protection. The wrong cleaner can also damage brick and mortar in ways that only show up months after sealing.
Every site is different, so we assess algae and green growth case by case and advise on the right preparation before sealing.
How to apply
Water test. Sprinkle water on a clean, dry patch and watch for a minute. Try a few spots on big jobs: old coatings are often patchy.
The pores are open. Ready to seal.
An old sealer or contamination is still there. Strip it, then test again.
In most of India, seal in the dry months just before the monsoon, so walls and floors go into the rains protected.
Best, just before the rains Good Monsoon, avoid
Mix 1 part concentrate with 25 parts deionised water (1:25) and stir well. Adjust for the job:
Care and re-application
The protection sits inside the pores, not on the surface, so foot traffic doesn’t wear it away the way it wears a film. It resists UV and thermal shock. Expect less than 5 years on heavily trafficked floors.

About using Stone + Brick.
No. It leaves no gloss or film, so colour and texture stay as they are. Always try a small, hidden area first to confirm on your particular stone.
It makes the surface water-repellent: rain and spills bead and run off instead of soaking in. It is not designed to hold back water under pressure, so it does not replace waterproofing membranes below ground or in tanks.
Yes, once the salts have been cleaned off and the wall has dried completely. Sealing a damp, salty wall traps the problem.
Not with acid: it strips the surface but leaves the growth alive in the pores and can harm brick and mortar. We assess algae on a case-by-case basis and advise on the right preparation before sealing. Ask us when you request a quote.
Applicators, contractors and facility teams, with standard spray, brush or roller equipment. We supply the concentrate in 10 L cans and help with the first job if needed.
Sealed, at 5–30 °C, away from frost and direct sunlight. Shelf life is 24 months unopened and 12 months once opened.
