RQ MASSETTO

Clear self-levelling epoxy resin for anti-slip ceramized floors

Description

RQ MASSETTO is a tricomponent product made up of:

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

The product is a polymeric system featuring RQ MASSETTO BASE (tricomponent) for the bottom layer and RQ MASSETTO FINITURA (bicomponent) for the finishing layer of concrete industrial floors.

It provides an industrial quartz floor coating offering extremely high mechanical resistance and an antislip surface perfectly in line with current regulations, easy to clean and keep disinfected.

High standard final looks

Usage field

RQ MASSETTO is used as a base and finishing layer for industrial type floors in the following sectors:

  • meat, fruit and vegetables processing companies, slaughterhouses, dairies, fishmongers, bakers, patisserie shops, etc;
  • kitchens and canteens in hospitals, restaurants and hotels;
  • cold stores, etc.

Clear self-levelling epoxy resin for anti-slip ceramized floors

Substrates preparation

Prepare the surface according to state-of-the-art resin floor requirements: the underlayment must be carefully examined to make sure it provides a suitable and structurally sound base.

  • Industrial quartz concrete can be coated over after  shot blasting, diamond wheel sanding or acid washing, provided humidity content is max 3%.
  • Sand and concrete footings must have been left to set for a suitable period of time (at least 28 days); max residual humidity must be lower than 3% (carbide measurement); they must also have higher than 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).
  • Any footing realized with SC 1 BASE-like binders plus various sand types can be coated over 12¸15 days later (20°C and 50% RH), after checking subfloor residual humidity.
  • 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 proceeding with RQ MASSETTO, make sure the underlayment is cohesive enough and does not show holes or depressions deeper than 3mm;
  • otherwise treat first the surface with a layer of  NORPHEN FONDO SL, finely dusted with 0.2-0.7 mm quartz sand (amount needed: approx. 0.8 to 1.0 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, apply a layer of NORPHEN FONDO SL and go ahead with RQ MASSETTO.

3) Surface humidity content higher than 4.5 %:

  • Apply a layer of NORPHEN SW SOLID, diluted 1:2 in water;
  • Level with W3 (amount needed: c. 1.5 kg/ m²;
  • Wait 48 hours before going ahead with RQ MASSETTO. 

4) Industrial quartz concrete:

  • shot blasting is the best way to prepare this type of surface before applying RQ MASSETTO.
  • On the now rougher surface you can apply a layer of NORPHEN FONDO SL, followed by quartz dusting, and finally RQ MASSETTO.

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 and more than 1 year old ->  fill the gap and make up a band of NORPHEN PU elastomeric resin reinforced with 160g/m² GLASS MESH strip. 
Product preparation
  • pour first into a container RQ MASSETTO BASE  component A, then component B and mix together to obtain a homogenous mixture;
  • add 10% (in weight) 0.1-0.3mm quartz sand and c.40% RQ MASSETTO component C (this is a mix of specially selected ceramized quartz sands, with specific particle size and mixed colours to obtain the desired final look);
  • mix carefully.
Product application
  • bring the now ready mix to the working area and pour onto the surface, spreading with a 48 cm smooth steel spatula;
  • proceed to cover 10 - 15m² surface area;
  • dust over lightly, while still wet, with the same type of sand found in the mix;
  • carry on to cover the whole surface area to be treated;
  • the day after, take away any sand not adhering to the surface, smooth over and remove all dust;
  • prepare RQ MASSETTO FINITURA by mixing component A and component B, without adding any quartz;
  • apply a coat of RQ MASSETTO FINITURA using a proper nylon spatula.

Working times

RQ MASSETTO average reaction times allow the operator to do a first rate job: you can expect it to be hardened up and ready to take the next product layer in 12 hours (at 20 °C).

Average Consumption

For a 3 mm thick coating, you will need:

  • 1.6 kg RQ-MASSETTO (A+B), together with
  • 4.5 kg ceramized quartz sand mix per m2

Colors

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

Warning and informations
  • Make sure room temperature is no 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 become less fluid, while in hot weather the mix sets faster.
  • Read carefully the safety card.

Do not use on:

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

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