Self levelling clear epoxy resin
for ceramized floors


FARMACRETE is a three component product:

  • component A:   a mix of liquid epoxy prepolymers;
  • component B:   copolymerization amine;
  • component C:   a mix of specially selected ceramized quartz sands.

It is a polymeric system made up of  FARMACRETE BASE (three component) to lay the underfloor and FARMACRETE FINISH (two component) to spread a finishing coat on (mainly industrial) concrete floors.

FARMACRETE owes its name to the great success met in the pharmaceutical and parapharmaceutical industry, since it combines extremely high mechanical resistance with a particularly smooth surface (quite suitable for disinfection procedures), together with extremely good looks.

Adheres well to any underlying base and is highly compression resistant.

Usage field

FARMACRETE can be used as a floor base and finish coating in the following sectors:

  • pharmaceutical and parapharmaceutical industry, doctor’s surgeries and various industrial environments requiring a highly resistant, beautiful floor for interiors assigned to dry working operations;
  • showrooms and exhibitions;
  • offices.

FARMACRETE BASE and FINISH are available in 20kg packs (A+B).

Substrates preparation

Prepare the surface according to state-of-the-art resin floor requirements: carefully examine the subfloor to make sure it makes up a suitable and structurally sound base.

  • Industrial quartz concrete can be coated over after shot blasting, followed by smoothing with diamond wheel or acid washing, provided its humidity content is max 3%.
  • Sand and concrete footings must be left to set for a suitable length of time (at least 28 days); max residual humidity must be lower than 3% (carbide measurement); they must also have a minimum  250 - 300kg/cm² compression resistance, otherwise you must increase it by deep impregnation with NORPHEN SW SOLID (diluted according to technical card instructions); you will need between 50 and 100 g pure product at least for each centimetre thickness of the surface to be consolidated.
  • SC 1 ready footings can be coated over after 8 days (20°C and 50% residual humidity).
  • SC 1-R quick ready footings can be coated over after 48 hours (20°C and 50% RH).
  • Footings realized with a SC 1-BASE-like binder and various sand types can be coated over after 12 - 15 days (20°C and 50% RH), after checking subfloor humidity content.
  • Tiled surfaces must be made rough using a diamond cup wheel.
  • Large wood panelled surfaces can be coated over after treating the gaps with NORPHEN PU reinforced with a 160g/m² GLASS MESH strip (about 5 - 7 cm wide), followed by fine dusting with 0.1 - 0.5 mm. quartz sand.
Specific preparation

1 - Surface humidity content lower than 3%:

  • Before you proceed with FARMACRETE, make sure the underlayment is cohesive enough and does not show holes or depressions more than 3 mm deep;
  • otherwise, before pouring FARMACRETE over it, spread a layer of NORPHEN FONDO SL using a spatula, and dust lightly with 0.3¸0.9 mm quartz sands coloured in line with the FARMACRETE quartz mix (you will need approx. 2.0 to 2.5 kg/m²).

2 - Surface humidity content between 3 and 4.5 %:

  • Apply a coat of NORPHEN SW SOLID diluted 1:2 in water;
  • the day after, spread a layer of NORPHEN FONDO SL and dust over as in 1), then proceed with  FARMACRETE.


3 - Surface humidity content higher than 4.5 %:

  • apply a coat of NORPHEN SW SOLID diluted 1:2 in water;
  • smooth over with NORPHEN W3 (amount needed: c.1.5 kg/m²);
  • wait 48 hours, then proceed with NORPHEN FONDO SL as in 1) before you go on to FARMACRETE.

4 - Industrial quartz concrete:

  • shot blasting is the best way to prepare this type of surface before applying FARMACRETE;
  • on the now rougher surface you can spread a layer of NORPHEN FONDO SL followed by quartz dusting as in 1) and finally FARMACRETE.

5  - Section gaps

  • Pay special attention to section gaps; this the procedure to follow:
  • industrial quartz floors up to 15 cm thick, less than 1 year old, with only one reinforcing mesh:
  • cut and seal  to finish;
  • floors as above, more than 18 cm thick and with two reinforcing meshes or else floors with only one reinforcing mesh (more than 1 year old):
  • fill up the gap and make a band of NORPHEN PU elastomeric resin reinforced with a 160 g/m² GLASS MESH strip.

FARMACRETE final colour is mainly due to the mix of ceramized quartz sands: you may require standard colours for small areas (see “BRIGHT STONE colours”) or special colours for larger ones.

Warning and informations
  • Do not apply on:

- parquet;
- linoleum;
- rubber;
- any surface likely to expand considerably on the joining gaps.

  • Make sure the working room temperature is not lower than 15°C.
  • Remember that you must keep working on the product; a team of people should be perfectly timed to get the next mix ready just as they finish with the previous one, with no gaps in between.
  • According to the room temperature, the product must be kept cool (in summer) or warm (in winter) because in cold weather resins tend to crystallize and thus become less fluid, while in hot weather the mix takes a little longer to set.
  • Read carefully the safety card.

Store indoors at temperatures ranging between +10 and +30°C.
