Depending on the type of aggregates mixed with NOVACEM MICRO TERRAZZO, the 28 days cured coating will develop a compressive strength that falls within the range of 35 to 50 Mpa. Additional information you may find at the Technical Data Sheet of NOVACEM MICRO TERRAZZO.
Substrate preparation:
Cement-based substrates have to be compact, level, clean, free of grease, oil, laitance and any substances which may compromise the adhesion of NOVACEM MICRO TERRAZZO. The minimum flexural strength shouldn’t be less than 1,5 N/mm2 and the minimum compressive strength at least 25 N/mm2. Existing cracks on the substrate should be bonded with the fluid epoxy resin EPO FLUID. On the still fresh EPO FLUID surface, scatter PLANOCOLOR GRANULATES S 500 silica sand or similar in order to create a uniform mineral surface. Absorbent substrates should be primed with PLANOPRIMER in order to increase the adhesion and provide a sealed substrate. Substrate of reduced strength should receive consolidation treatment by means of NOVAPRIMER or WATER PRIMER EPX and full coverage with the sand PLANOCOLOR GRANULATES S 500, by scattering on the still wet primer surface.
Existing floor coverings such as ceramic tiles, gres porcelain, marble, terrazzo, etc. are required to be firmly attached on the substrate. These types of substrates also have to be clean and free of laitance or any substance which will compromise adhesion on them. If required, use for cleaning one of the following products: ALCALINE CLEANER or ACID CLEAN or ACID CLEAN TURBO depending on the type of stain, and rinse well with water. Prime the clean and dry covering with PLANO CONTACT. For external and wet area applications, the substrate has to be waterproofed first by using SC ELASTIC or SC 200 PENETRATE.
Preparation of the mix:
In the bucket containing the powder empty the recipients containing the PREMIUM LATEX and the pigments in liquid form NOVACOLOR DESIGN, according to the desired color, of the relevant PLANOCOLOR MICROCEMENT color chart. According to the required workability for every 1kg of PREMIUM LATEX 1-1,5L of clean water must be added. Mix by means of electrical stirrer for at least 3 min until you obtain a uniform mix free of lumps. Then, while stirring add the granulates at a rate depending on the aesthetics requirements of the application. The mix has to be used within 45 – 60 min after mixing in normal conditions. After this time don’t try to soft the mix by adding water.
Application:
The laying of the mortar follows the general rules applicable to low thickness floor coatings. Apply the fluid mixture on the substrate in one layer and of thickness 2 – 3 times the maximum aggregate grain size by using a flat plastic or metal trowel. Then smooth the surface.
Depending on the composition of the mixture and the conditions of application the grinding process begins after 24 – 48 hours. For the mechanical and abrasive agents always follow the manufacturer’s instructions such as suitability, rotational speed, wet or dry processing.
Small air bubbles developed in the mortar during mixing, may appear in the form of pinholes or small cavities, on the surface during grinding process. Filling of these holes is recommended to take place during initial grinding at intermediate stage when all embedded aggregates appear uniformly on the surface. After thoroughly cleaning the entire application area from the dust and abrasive residues by rinsing with water and sucking the waste water, smoothing can be done by using NOVACEM MICRO TERRAZZO mix without the addition of granulates. Alternatively, but only for indoor applications, you can use PLANOFINISH CRYSTAL to fill the pinholes.
Expansion joints:
The expansion joints incorporation depends on the use of the surface and the dimensions of the area. In internal areas every 5 – 7 linear meters and in external areas every 5 linear meters.
Recommendations:
• Apply only on solid and properly primed substrate
• Do not add water in quantity higher than the recommended and do not add water when the mixture starts to set
• Do not cover or apply the product over existing expansion joints of the substrate
• Do not apply the mortar on substrates with rising damp or in total water immersion without substrate waterproofing
• Do not add cement, gypsum, lime or other binders which may influence the properties of the mortar
• Don’t apply the mortar on substrates and/or areas when temperature less is than +5°C or higher than +35°C
• Do not apply directly over anhydrite screeds, metal or flexible substrates with high deformability and intense vibration
• Do not apply upon deformable substrates, surfaces subjected to vibration
• Do not apply upon non-absorbent substrates such as metal, glass, old ceramic tiles and mosaics without applying appropriate primer
• Application must be done by professional applicator
Refer to the Technical Data Sheets as well as the Safety Data Sheets of the products listed here.

The consumption depends on the mixing ratio of the granulates and the cement based binder NOVACEM MICRO TERRAZZO.
