Growseal™ Nano-brush Coat nano-modified coating offers Superior Waterproofing Performance Novel cementitious Environmental Waterproofing Coating with high flexibility and excellent adhesion.

Incorporating Nanotechnology into Traditional Cementitious Waterproofing Coating

Traditional cementitious waterproofing coating has low flexibility and poor bonding strength on concrete substrate.  With the help of nanotechnology a novel cementitious waterproofing coating is developed to have high flexibility and excellent adhesion on the substrate.

Nanotechnology
Nanoparticles having at least one dimension in the nanometer range can enhance the tensile strength, ductility, adhesion and other performance when they are efficiently incorporated into a coating system with uniform dispersion.  A methodology has been developed to disperse the nanoparticles in the coating in order to modify the polymer cementitious coating, achieving higher elasticity and superior waterproof performance.

◎ High Flexibility with >300% Elongation Value.
The incorporation of nanoparticles promotes a new load transferring mechanism in achieving high flexibility with good tensile strength, and thus covers minute cracks causes by various reasons.		Please click to enlarge

◎ Low VOC
◎ Easy Application (Applied with a Brush, Roller or Spraying Method).
The two-component cementitious coating materials can be easily mixed by using a common site mixer.  The mixed coating materials can be applied to damp surface of freshly placed concrete in new construction or restoration sites.

Application
The superior performance, easy application and cost-effective features further enable the developed coating to be easily applied to various construction waterproofing fields including basements, toilets, kitchens, terraces, swimming pools, water tanks, decks and flat roof.
● Direct application on damp surfaces.
● Adhesion to the substrate can be maintained over time.
● Excellent waterproofing qualities-able to withstand high hydrostatic pressure.
● Formation of a more solid and durable coating with good mechanical performance.
● Pre-packed - Easy to mix and apply.
