NATURAL STONE COATINGS - 2) APPLYING RESIN COATINGS ON NATURAL STONE - BASE CYCLES

2.1. Applying film resins on stone (with a maximum moisture content of 3% measured according to the calcium carbide method)

NORPHEN 200 - NORPHEN 200 HCR (all versions) - NORPHEN 200 FUEL - NORDPUR INTERNI - NORDPUR ESTERNI (all versions)- NORDPUR SW:

In few rare cases the client requires the installment of a resin film over existing stone coatings, even if there are such incoherences on their surface that the results of the work will be badly compromised.

However, in the case of either marble or granite jointless slabs, the result is acceptable: it will be sufficient to fill with PLAST EPO the small bevels between each slab, if existing, and then to polish with a diamond grinding wheel.

 

2.2. Applying waterborne resins films on stone slabs (with moisture content greater than. 3% up to 6% measured according to the calcium carbide method) WITH JOINTS THAT WILL BE EXPOSED.

(NORPHEN SW SMALTO - Q_SMALTO - Q_SMALTO LC)

The product shall be applied directly on the stone after washing and brushing it with STRIPPER 5-fold diluted in water and then rinsing.

 

2.3. Applying either solvent free or solvent-based film resins with high mechanical strength on a stone substrate (with a moisture content greater than 3% up to 6% measured according to the calcium carbide method) WITH JOINTS THAT WILL BE EXPOSED.

(NORPHEN 200 HCR - NORDPUR ESTERNI - NORDPUR INTERNI)

  • wash and brush the stone with STRIPPER 5 folds diluted in water and then rinse;
  • apply a coat of SOLID;
  • proceed with the application of the coating.

These are medium-thick coatings that are processed utilizing the self-leveling method; Proceed as follows:

  • diamond grind the surface;
  • apply a skim coating with 0.50 kg / sqm of NORPHEN FONDO SL loaded with 30% quartz 0.1-0.3 andslightly broadcast with 1 kg of quartz sand 0.1-0.6;

then:

  • for FLOOR L TRA, NORPHEN LEVEL and DECORLITE: apply a coat of either NORPHEN W3 or W3 IMPERMEABILIZZANTE loaded with 30% quartz sand 0.1-0.3 - wait 48 hours and proceed.
  • for LEVEL CRETE: replace the quartz 0.1-0.6 with LIGHTLY BROADCAST quartz 0.7-1.2 during the application phase of NORPHEN FONDO SL to obtain a better grip;
  • for STRATOFLEX and STRATOFLEX PU: apply directly on the broadcast, taking care to facilitate the removal of the air from the product with a spiked roller.

 

2.5. Applying coatings of the series RQ MASSETTO - FARMACRETE - NORPHEN W3 COLORATO on a dry substrate (max 3%)

They are medium / high thickness coatings that undergo a multi-layer processing method with broadcast.

Proceed as follows:

  • diamond grind the surface;
  • prepare a dose of 0.50 kg / sqm of NORPHEN FONDO SL and add 50% quartz 0.1-0.3;
  • skim coat the surface and spread with a 48 cm steel trowel;
  • wet on wet broadcast to excess NATURALE quartz sand 0.3-0.9 for NORPHEN W3 and COLORATO of the same colors of the finish for RQ MASSETTO and FARMACRETE;
  • the next day remove the excess quartz, sand and suck up the dust.

Applying medium and medium /high thickness coatings of all types (FLOOR L TRA - NORPHEN LEVEL - DECORLITE - LEVEL CRETE - STRATOFLEX - STRATOFLEX PU - RQ MASSETTO - FARMACRETE - NORPHEN W3 COLORATO) on surfaces with a moisture content ranging from 3 to 6% (measured according to the calcium carbide method)

Proceed as follows:

  • diamond grind the tiled surface so as to remove the glossy surface;
  • lay down a 160 gr / sqm fiberglass mesh and fix it to the surface with SOLID using a roller for a coverage of approx. 300 gr / sqm; broadcast with the supplied quartz;
  • after approx. 2 hours apply SOLID with a spatula for a consumption of about 400 gr / sqm and broadcast with quartz supplied;
  • after approximately another 2 hours or so, proceed with the rest of the floor.

 

2.7. Applying medium and medium /high thickness coatings of all types (see above), on surfaces with moisture content greater than 6% (measured according to the calcium carbide method)

  • diamond grind the tiled surface so as to remove the glossy surface;
  • apply one coat of Q-PRIMER with a roller, diluted in water as per Technical Data Sheet;
  • skim coat the surface with Q-RASANTE (A + B + C) for a consumption of approx. 1.5 kg / sqm;
  • wet on wet broadcast to excess either natural or colored quartz depending on the type of coating to be installed;
