How to test and treat surfaces such as marble and granite worktops.


Minerals (Marble and Granite) are notoriously difficult to assess in terms of their porosity and calcium content. This is why we recommend customers to go through a testing stage after the surface has been cleaned. Here's how it's done:

Important: before you try any of these tests, you must first remove any traces of previous coatings or cleaning agents. Unless otherwise stated in the Product Information or Application instructions, our products must always be applied to a CLEAN SUBSTRATE.
Cleaning the surface depends on whatever was previously applied to the surface. Petrochemicals, for example, need an alcohol-based cleaner to remove traces of this and then they require a deep clean with Nanolia Preclean or Glass polish depending on the substrate.
This has then to be washed off with clean water and left to dry before applying the product as thinly as possible.

UNLESS OTHERWISE STATED IN THE PRODUCT LITERATURE, DO NOT APPLY ANY OF OUR COATINGS ON TOP OF A DIFFERENT TYPE OF COATING!

Once the surface is clean and dry, the testing can commence.

Apply a droplet of water to the surface and observe what happens to it.
1. If it beads up and does not sink into the substrate then the top should be treated in the same way as glass.

2. If it beads up but then sinks into the substrate then use Nanolia Stone Coat. This will leave a film on top which will need to be polished afterwards.

3. If the surface to be treated is glassy and it is a coating which is preferred then Powercoat should be used.

If Stone coat does not achieve the desired result then try Glass Pro – If that does not work try Powercoat. Do not test on the same place!

TO SUMMARISE:

Always test a small sample to ensure that the desired result is achieved before proceeding with the main project. If in doubt, do not proceed.

  • CLEAN THE PRODUCT WITH ALCOHOL BASED CLEANER THEN PRE-CLEAN OR GLASS POLISH
  • WASH THE SUBSTRATE WITH CLEAN WATER AND LET DRY
  • APPLY A DROPLET OF WATER TO ASSESS THE POROSITY
  • APPLY A VERY THIN LAYER OF EITHER STONE COAT, GLASS PRO OR POWERCOAT

STONE COAT
Use undiluted. Application temperature between +5 ° C and 50 ° C. Maximum humidity 95%. The surface must be dry, clean and free from grease and oil. Dust and loose residues Plaster / Cement / Sand / chalk must be removed thoroughly
Apply by brush, roller or spray. Depending on absorbency apply in one or two operations approx 10-15 minutes apart to complete saturation. Test first to avoid puddling. The surface should be protected for 24 hours after treatment before exposure to rain or water condensation. Within this period avoid close proximity or contact. The drying time can be accelerated by ventilation. Any rain or water falling on the surface in the first 7 days after application should be removed immediately. Chemical resistance increases progressively over the first 4 weeks. Avoid the use of alkaline floor cleaners during the first 4 weeks. Adjacent mineral surfaces such as glass or tiles should be protected against splashes. Avoid contact with aluminium. Wash off any impurities immediately with water. Application equipment can be cleaned with water.

GLASS PRO

Use undiluted. Do not use at a temperature under 5°C. Do not use in direct sunlight. When using indoors, be certain that there is adequate ventilation at the working place. The surface to be coated must be completely clean and free from fats/oils. The effectiveness and life-span of the finished coating is highly dependent on the preparation of the surface. We recommend the use of Nanolia Glass Polish to prepare the surface. After the surface to be treated has been cleaned it should be thoroughly rinsed-off using clear water and left to dry before proceeding with application of Glass Pro.

Mix the component A with component B in the proportions 1:1 (by volume). Using a lint-free cloth, apply the product to the surface evenly and immediately polish off to a smooth surface free of “striping”. If the surface has “striping”, due to the application of a too thick coating of the product, this may be polished out by the use of a cloth soaked in alcohol.
The protective effect of the product starts after only a few minutes and continues to strengthen over the next few days.
For really heavy duty industrial applications, a subsequent thermal treatment may be employed at a temperature of 220°C for 20 minutes to provide increased adhesion and resistance against frictional forces.
The container with the original product should be securely closed and sealed immediately after use. In the event of a reduction in efficiency, a new coating can be applied at any time. Following the mixing procedure the finished coating solution is able to be used for about 24 hours.

POWERCOAT

Apply at a temperature between +5 °C and +40 °C. Avoid direct sunlight. The surface should be cleaned (free from fats, polishes, waxes and surfactants), dry and free from dust and any fatty/oily materials. The base surface to be treated must be thoroughly cleaned, dry and free from fat/oil, and also free of any silicone, wax or polish traces using Nanolia PreCleaner. Pre-treatment with Acetone is not sufficient.

Application is possible using the accepted methods (rolling, brush-painting, spraying or by immersion). To achieve the most successful surface HVLP Spray application is recommended. It can be applied alternatively with a roller or a lint-free cloth. Irregularities and striping of the surface can be corrected by the use of a PU-foam roller (using high pressure on the roller).

NB: read the information sheets carefully. Do not forget we are dealing with chemicals and chemical reactions and it is therefore very important to understand how and why our products do what they do.

When used correctly be assured there is no better product on the market!
