          • humidity stable marble and natural stone
    • applications on horizontal or vertical surfaces such as:
          • wet areas like shower rooms and WC
          • medium traffic floors
    • application on various substrates like:
          • properly cured concrete and cement screeds
          • non-absorbent substrates (after suitable primer application)
          • plaster and masonry mortars
          • cement boards and gypsum boards (after suitable primer application)
  • Form: powder
  • POT life: 4 hours
  • Open time: 20 minutes
  • Small corrections: 30 minutes
  • Walkability: after 24 hours
  • Grouting on wall: after 10 - 12 hours
  • Grouting on floor: after 24 hours
  • Application temperature: from +5°C up to +35°C

Substrate preparation:

The substrate has to be compact, clean, free of grease, oil, laitance and any substances which may compromise the adhesion of MK 1000. Concrete based substrates should be prepared in example by grinding, in order to obtain a uniform flat mineral surface without protruding spots.
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 paper bag containing MK 1000 (20 kg) with 4,8 – 5,2 liters of clean and fresh water by means of appropriate electrical stirrer at low speed (500 rpm) for at least 3 – 5 min, until a uniform mortar free of lumps is obtained. The mix has a pot life of 4 hours. 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.

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 MK 1000 in normal temperature and humidity conditions is more than 20 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 MK 1000 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 areas where resistance to strong chemicals is required like in example kitchen benches 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 MK 1000:

  • 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

Also note the following:

  • Never exceed the maximum recommended quantity of mixing water
  • 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 MK 1000 is still fresh. After hardening occurs, cleaning can take place by mechanical means.
