Strata NANO-COTE is a solvent free, self-assembling micro emulsion. The small molecular chain is creating a capillary impregnation without filling the pores and capillary structure. The product is designed as a water-soluble impregnating agent for masonry, including highly alkaline cement based surfaces. It chemically bonds with concrete and masonry substrates and becomes invisible once dry. Its penetration and subsequent chemical reaction with the concrete allows it to provide long term protection for cement based substrates by significantly reducing the ingress of liquid water and any dissolved salts and contaminations that the water may carry.

STRATA NANO-COTE concentrate diluted can be used for the water repellent treatment on following substrates:

• Concrete
• Pavers
• Bricks
• Plaster , Render
• Fiber Cement products
• Roof tiles
• Porous natural stones

  • Lasts approx. 8 years.

  • Lower purchase price.

  • More cost effective in the long run as more durable.

  • Aquaseal is not harmful to plants – (we do advise covering delicate or important plants)

  • Nano is not harmful to plants – (we do advise covering delicate or important plants)

  • Nontoxic to people and pets, unlike many others on the market.

  • Nontoxic to people and pets, unlike many others on the market.

  • Aquaseal can be applied to damp surface.

  • Nano can only be applied to completely dry surface.

  • Aquaseal will etch glass and joinery – so covering prior to sealing is recommended.

  • Nano does not etch glass and joinery (it can leave a light residue, so is advised to cover windows prior to sealing)

  • Fume free and non-flammable.

  • Not corrosive, non-flammable and non-carcinogenic. Odour/fume free.


  • Penetrates deeper into the brick or stone than Aquaseal.


  • Does not rely on solvents and other hazardous materials for penetration


  • Meets modern environmental and other building  standards and requirements
