Nano waterproof agent potassium methyl silicate

Penetrates Deep, Protects from Within

Unlike surface coatings, this nano-technology penetrant soaks into concrete, brick, and stone, forming a hydrophobic barrier deep inside the material. The surface looks and feels unchanged — but water beads off and cannot penetrate. Ideal for protecting exterior walls against sandstorm erosion, coastal salt spray, and desert humidity cycles.

  • Deep penetration — 3-8mm into concrete and masonry
  • Invisible — no surface film, no color change, no sheen
  • Breathable — allows moisture vapor to escape
  • Protects against sandstorms, salt spray, freeze-thaw, efflorescence
  • Water-dilutable concentrate (42-52%) — cost effective
  • 10+ year protection lifespan
  • Available in bulk (5L, 20L, 200L drums)

Where to Use Nano Waterproof Agent

Invisible protection for porous building materials

Exterior Concrete Walls

Protect exposed concrete facades from rain, humidity, and sandstorm erosion without changing appearance.

Natural Stone & Brick

Heritage buildings, stone cladding, decorative brick — keep the original look while adding water resistance.

Coastal Buildings

Prevents salt spray penetration and efflorescence on buildings near the sea — critical in Gulf coastal cities.

Concrete Infrastructure

Bridges, tunnels, retaining walls — extend service life by preventing water and chloride penetration.

Frequently Asked Questions

How does nano waterproof agent work differently from regular coating?

Unlike surface coatings that form a film, nano waterproof agent penetrates 3mm+ into the substrate and creates a hydrophobic barrier inside the capillary structure. It does not change the surface appearance and maintains 95%+ breathability. Water beads off the surface while moisture vapor can still escape.

How long does nano waterproof agent last?

Nano waterproof agent is based on inorganic silicone chemistry (potassium methyl silicate) which does not degrade under UV or heat. Expected service life is 10-15 years on exterior walls. It withstands temperatures from -40°C to +150°C.

Can nano waterproof agent be used on natural stone buildings?

Yes. It is ideal for natural stone, limestone, sandstone, and historic buildings because it penetrates without forming a visible film. The original appearance and texture are fully preserved. Widely used for heritage building conservation.

Need Nano Waterproof Agent in Bulk?

Available in 200L drums for large projects. Custom dilution ratios available.
