Substrate preparation:
The substrate has to be compact, clean, free of grease, oil, laitance and any substances which may compromise the adhesion of NOVACOL SUPER. The minimum tensile strength of the substrate must be at least 1,5 N/mm² and the minimum compressive strength at least 5 N/mm².
Existing ceramic, gres porcelain tiles, marble and stone coverings on floors and/or walls must be firmly attached to the substrate and free of laitance on their surface which may compromise adhesion. If required clean the coverings with appropriate detergent, depending on the type of dirt, like ALCALINE CLEANER , ACID CLEAN or ACID CLEAN TURBO and rinse with plenty of water. Prior to the application of tiles a primer coat of PLANO CONTACT should be applied.
On absorbent substrates like concrete, cement screeds etc. especially on hot and/or windy days saturate well the substrate with water and remove excess with appropriate toll like sponge. For additional information refer to the Technical Data Sheets of the relevant products.
Preparation of the mix:
Mix the content of the 25kg paper bag containing NOVACOL SUPER (25 kg) with 6 – 7 liters of clean and fresh water by means of appropriate electrical stirrer at low speed for at least 3 – 5 min, until a uniform mortar free of lumps is obtained. During hot periods and in general, it is recommended to avoid direct sunlight exposure of the materials (in powder or liquid form) before use, otherwise the working time is reduced. In any case avoid mixing by hand. If there is requirement for deformable tile adhesive, like for example for application of large size tiles, it is recommended to add 8% by weight of the enhancing latex SBR 50 and reduce water by 4 - 6% by weight.
Application:
The tiles are placed on the still fresh adhesive bed, by applying firm pressure, in order to ensure full contact between the tiles and the adhesive. The open time of NOVACOL SUPER in normal temperature and humidity conditions is 30 minutes. Unfavorable weather conditions like contact with strong direct sunlight, drying and/or hot wind or a very absorbent substrate may reduce open time significantly. For this reason it is important to check if the adhesive has formed a superficial skin. If such incident occurs, remove the adhesive from the substrate and reapply it, before applying the tiles. Small corrections must take place 30 minutes after tile application. Surfaces tilled with NOVACOL SUPER should not be exposed to rain, strong sun or frost for at least 24 hours.
Grouting:
Grouting can take place 12 - 24 hours after the tile application. For large size tiles this waiting time might be prolonged. For grouting joints up to 10mm width it is recommended to use of NOVAGROUT F. For rectified tiles or when the requirement is for very smooth grout surface, NOVACOLOR GLASS can be used. For wide joints of 5 - 20mm NOVAGROUT G. For areas where resistance to strong chemicals is required like in example swimming pools or industrial floors it is recommended to use the epoxy grout NOVAGROUT EPOXY. For additional information refer to the Technical Data Sheets of the relevant products.
Recommendations:
Avoid using NOVACOL SUPER:
- In cases where the substrate and environment temperature is less than +5°C or higher than +35°C
- In a thickness higher than 10mm
- On substrates like metal, wood or surfaces like polyurethane, acrylic and similar paint or coatings (use NOVACOL 2K ELASTIC)
- On PVC, asphalt membranes and in general materials which polymerize in the long run
- For bonding humidity sensitive marble and natural stones
- On friable or not properly cured substrates
- Over existing expansion joints
- Over not absorbent substrates without appropriate primer
- Under direct sunlight and/or strong wind
Also note the following:
- Never exceed the maximum recommended quantity of mixing water
- For tiles with a side greater than 60cm add to the water, depending on the requirements, the plasticizer emulsion SBR 50
- For tiles of total surface over 900 cm² the double-spreading (buttering) technique of adhesive is always recommended
- Protect the tilled surface from rain and frost for the first 24 hours
- Do not add cement, lime, gypsum or other binders or substances which may affect the mortar characteristics
- Application should be performed by professional skilled workers
Cleaning:
Tools, buckets, tiles etc. can be cleaned with fresh and clean water as long as, NOVACOL SUPER is still fresh. After hardening occurs, cleaning can take place by mechanical means.
