Getting acquainted with NANO SEAL Products


Product Range





Rich Coatings manufactures different NANO SEAL range of products to suit different applications and sometimes for specific needs. We do this to achieve optimal results and to obtain the best possible finish. However, this is not to say that for e.g. NANO WOOD SEAL cannot be used effectively as a primer on a plastered wall. Interchanging the uses for the products will NORMALLY not make that much of a difference and will always offer very good protection. They are however graded specifically for optimal results.



  • NANO SEAL SP 20 is designed for deep penetration into the steel surface.
  • It is also suitable for most non porous surfaces including glazing, tiles, vinyl, plastic, fibreglass, composite materials and over-coating of existing painted surfaces.
  • Although NANO SEAL SP 20 can be painted directly onto steel as a rust protection coating, we recommend that the surface be primed with our ETCH 3 PRIMER to provide a good etch into the steel. This will ensure that the steel is well protected from the elements and that you will have a long life coating applied on the surface.
  • NANO SEAL SP 20 can be over coated with any coating that has a high glue content.



  • NANO SEAL SP 25 is designed for deep penetration into porous surfaces such as brick and mortar, driveway paving, face-brick structures, rock features, clay pots and tiles, ceramics,
  • NANO SEA SP 25can also be used on most any surface, for maximum benefit we recommend that it be used as instructed.
  • NANO SEAL SP 25 can be over coated with any quality coating that has high glue content.



  • NANO WOOD SEAL is designed for the sealing of wood surfaces.
  • While NANO SEAL SP 25 would also work over wood surfaces, it is more economical to use the NANO WOOD SEAL coating as this product is slightly more viscous and hence fewer coats are required to obtain the desired gloss finish.
  • For wood staining, we recommend that the stain be applied before coating with NANO WOOD SEAL because once sealed, no stain will be able to penetrate the NANO WOOD SEAL coating.
  • Lightly sand the surface before applying the first coat of NANO WOOD SEAL to ensure a smooth shiny finish.



All coatings are only as good as the surface onto which they have been applied. Preparation is therefore of the utmost importance.


All substrates should be sound, clean, dry, and free of dust, grease and oils before application.

Refer to each product for specific preparation guidelines. If in doubt please call out helpline.



  • Brush painting
  • Roller painting
  • Spray painting
  • Airless spraying
  • Dipping*


*In addition to the traditional methods, a unique method has been developed to ensure 100% coverage of internal and external surfaces:  Hydro-Displacement. This method is made possible by the hydrophobic characteristic of NANO SEAL repelling water the moment NANO SEAL comes into contact with a surface.


Hydro-Displacement is based on the principles of a dipping tank but provides a cost effective alternative using a body of water and a layer of NANO SEAL flotation. An item or object can be passed through the layer of NANO SEAL into the water below (First Coat) and as the item/object is removed from the tank it passes through the NANO SEAL layer again for a second coat (Second Coat).  Allow the item/object to drain off and allow to dry before over coating if desired.


Using a similar method, the inside of a tank can be coated with NANO SEAL. Contact us for further information on the hydrophobic properties and uses of NANO SEAL products.


Spread rate:

The theoretical spread rate is 100 – 200 grams/depending on the absorption rate of the substrate. Depending on the porosity and absorption of the substrate the coverage can vary from 15m²/lt to 50m²/lt. On glass NANO SEAL SP 7 can spread up to 200m²/lt using the correct application procedures.


QUV testing:

QUV Testing is a Q-Lab test used to do accelerated artificial weathering in order to test the durability of a coating or product. Testing is conducted in a laboratory where salt water is continuously sprayed at the target. Conditions are strictly controlled including the pressure, the temperature, the level of salt etc. and of course the time is measured. Every 100 hours that the test runs is equivalent to 1 year of natural weathering in coastal conditions.


Testing of NANO SEAL SP 20 as an intermediate coat on a steel tile surpassed the 6000-hour mark without any signs of deterioration. This is the equivalent of 60 years in coastal weather conditions.
