NOVACEM TERRAZZO

Cement based hydraulic binder for creating terrazzo coverings

Cement-based hydraulic binder enhanced with additives that facilitate application on floors. It is mixed with PLANOCOLOR GRANULATES MR (marble), PLANOCOLOR GRANULATES LC (light & coated) and/or PLANOCOLOR GRANULATES RC GLASS recycled glass granulates in order to create highly resistant to wear polished terrazzo coverings. It can also be mixed with pigments such as NOVACOLOR OXIDE or NOVACOLOR UNIVERSAL. The covering is applied in a minimum thickness of 15 mm on floors depending on the grain sized of the used granulates. For polished terrazzo, grinding is done with a suitable machine after 24 – 72 hours, up to the desired gloss level.

Substrate preparation:

Concrete and cement mortars must be dry, sufficiently mature, and free from the risk of cracking. Furthermore, the surface must be free of dust, dirt, oils, grease, rust, and other elements that will interfere with adhesion. Remove all loose and friable sections of concrete or cement mortar until the substrate is compact and firm with a tensile strength of at least 1.5 N/mm². Existing cracks should be repaired with two-component injectable epoxy adhesive EPO FLUID. Substrates with low mechanical strength must be reinforced with NOVAPRIMER or WATER PRIMER EPX, as needed.

For monolithic bonding to the substrate use EPO FLUID or alternatively the adhesive primer consisting of 1part SBR 50, 1 part water and 4 parts NOVACEM TERRAZZO and apply the mortar fresh on fresh to the adhesive layer.

Preparation of the mix:

Fill a suitable concrete or pan mixer with the required amount of water. Add NOVACEM TERRAZZO to the water slowly while stirring, followed by the aggregates. Mix for at least 3 minutes, or until the mixture is completely homogenized and free of lumps. The mixture is now ready to be used.

Application:

Using a flat spatula or trowel, apply the mixture. Final smoothing can be accomplished with finishing tools such as a flat metal trowel. The application thickness is determined by the maximum grain size of the aggregates used.

Under normal conditions, the mortar should be applied within 45 - 60 minutes of mixing. After this time, do not attempt to mix it with water again. Low temperatures prolong the life of the mortar, whereas high temperatures significantly reduce workability.

It is recommended to use the mineral hardener/concrete densifier PLANOFINISH CH PLUS 24 - 48 hours after the application.

Polishing:

It is done with a suitable sanding machine 24 - 72 hours after application. To seal micro-holes caused by trapped air during mechanical grinding, use NOVACEM MF in the corresponding shade as a filling material.

After the initial surface sanding, use the special water-based hardener/condenser PLANOFINISH CH to increase gloss and surface mechanical resistance. After using abrasives of 200 or 400 grit, this is the recommended application.

PROTECT 900 S provides water- and oil-repellent protection.

Expansion joints:

The location of each expansion joint is determined by the surface's use and the geometry of the space. The general rules for mortar manufacturing, as well as the guidelines of the BS 8204-3 standard, must be followed.

Recommendations:

  • Apply in structurally stable and well-prepared surface
  • Avoid application with direct exposure to sunlight and/or strong wind as well as rain
  • Once the mixture begins to set, do not add any more water or additives
  • Do not apply to existing substrate expansion or movement joints
  • Do not mix NOVACEM TERRAZZO with gypsum, cement, resins, latex, or other binders
  • Do not use on non-absorbent substrates such as metal, glass, old ceramic tiles, and mosaics without first applying an appropriate primer
  • After 7-10 days, complete immersion in water
  • Do not apply when temperature of the substrate and environment is lower than +5°C and higher than +30°C
  • Do not apply directly to anhydride substrates, metal, flexible or high vibration surfaces
  • It is not recommended to use different batches on uniform surfaces. Where a specific shade is required, mixing with NOVACOLOR OXIDE or NOVACOLOR UNIVERSAL in an appropriate proportion is recommended
  • Application must be done by professional applicators

Cleaning:

Tools used during the preparation and application can be cleaned with water while NOVACEM TERRAZZO is still fresh. If hardening occurs, cleaning can be done only by mechanical means.
