NATURAL BASE QUARTZ

Two-component rendering for surfaces to be coated with the NATURAL range CE MARKING EN 13813 – SR-B2,0

Description

NATURAL BASE QUARTZ is a three component product consisting of:

  • component A: aqueous dispersion of liquid epoxy prepolymers, additives and special fillers.
  • component B: aqueous dispersion of  copolymerization polyamines and additives;

NATURAL BASE QUARTZ is a product designed specifically for creating very hard layers, without shrinkage, on surfaces to be treated with subsequent layers of polished plaster products in the NATURAL range, both on floors and walls.

 NATURAL BASE QUARTZ is CE marked to EN 13813 as SR – B2,0 (“materials for synthetic resin screeds”).

Usage field

On floor and walls surfaces such as:

  • screeds and concrete floors of every composition;
  • painted walls (previously diamond grinded);
  • wood panels, plywood panels, plasterboard, polymer cement and aluminium without primer;
  • Tiled surfaces (previously diamond grinded or treated with RICRETE 1C);
  • Natural stone (with removal of previous treatments);

Application

 

 

Substrates preparation

Care must be taken to ensure that the substrate is a structurally sound and suitable base. This is particularly important when work is to be carried out on areas which, when put into use, can be negatively affected by episodes of negative pressure caused by humidity.

Depending on the area existing condition, the kind of treatment to be performed shall be chosen between the following:

  • Pressure hot water washing;
  • acid washing;
  • sanding;
  • diamond-grinding;
  • scarifying
  • sand-blasting.

In this way dust, dirt, grease, oil, old glue or varnish,, efflorescence, rust, mould and other foreign material will be removed.

Any area’s dips or humps having a depth higher than 5-10 mm must be filled with GROVE 30.

Specific preparation

Substrate Preparation with cracks or joints: See Technical Data Sheet

Product preparation
  • pour NATURAL BASE QUARTZ comp. B into comp. A mix well with a professional blender at low rpm;
  • the mixture obtained is ready to use.
Product application
  • place a 160 g/m2 glass mesh with a 4x4 mm weave onto the laying surface without overlaps;
  • use a square trowel to load the product onto a steel spatula of around 50 cm (46 x 10 cm for vertical surfaces), apply it to the mesh, on the floor or on the wall, and spread it out to approximately 1.5 kg/m2.
  • After 4 hours (at 23°C) apply the second finishing layer.
