Cement based substrates have to be compact, level, clean, free of grease, oil, laitance and any substances which may compromise the adhesion of PLANOCOLOR PREMIUM 2K. The minimum flexural strength shouldn’t be less than 1,5 N/mm² and the minimum compressive strength at least 25 N/mm². The application surfaces must be dry and protected from rising humidity with max moisture content <4% by weight measured with the CM or Darr method. Concrete substrates should be first properly prepared by mechanical polishing in order to obtain a uniform absorbent substrate with open porosity without protruding edges. If levelling is required, it is recommended to use mortars with controlled shrinkage and drying such as PLANO 120, RC 240 or NOVACEM RAPID FLOW according to the requirements of each application. 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 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 like in example ceramic tiles, gres porcelain, marble, terrazzo etc. have to be firmly attached on the substrate. They also have to be clean and free of laitance or any substance which will compromise adhesion on them. If required, use for cleaning ALCALINE CLEANER or ACID CLEAN depending on the type of stain and rinse well with water. Prime the clean and dry covering with PLANO CONTACT. For external area applications, swimming pools the substrate has to be waterproofed first by using SC ELASTIC or SC 200 PENETRATE. For additional information refer to the Technical Data Sheets of the products.
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 - 1,5 L of clean water must be added. This water is used to clean the recipients of both PREMIUM LATEX and NOVACOLOR DESIGN, in order to ensure the uniform color between different buckets mixes as well as that all the quantity of both products is inside the mix. Mix by means of electrical stirrer for at least 3 minutes until you obtain a uniform mix free of lumps. The mix has to be used within 1,5 hours after mixing in normal conditions. After this time don’t try to soft the mix by adding water. Low temperatures extend and high temperatures reduce the workability of the mix.
Application of the mix:
Apply two or three coats according to the desired finish. On horizontal surfaces apply the first coat by means of a notched trowel 6 x 6 incorporating, inside the still fresh mortar, the alkali resistant NOVAMIX FIBERGLASS NET. The net incorporation is recommended also for vertical surfaces in order to function as a thickness indication of the coating. Apply a second coat after the coating becomes hard after 6 hours in normal conditions, ensuring that the net is fully covered. If required, an additional coating or subsequent coatings can be applied in order to reach the desired pattern. It is recommended to prime between coats with PLANOPRIMER diluted 1:1 with water. In order to obtain an extra smooth and minimal texture it is recommended to slightly sand the finished surface, in order to eliminate any small irregularities. The sandpaper grain size must be chosen according to the requirements. After 24 hours form the application of the coating and after checking humidity content, an appropriate waterproofing sealing system must be applied. One of the DRY BRIGHT, PROTECT 200, PLANOFINISH EPOXY or any of the PLANOFINISH PU varnishes can be used, according to the requirements of each application. For applications inside swimming pools it is recommended to use PLANOFINISH PU 2KS. For additional information refer to the Technical Data Sheets of the products.
