High-performance super-fine ceramic tile and natural stone grout for joints from 0 - 8mm CG2 WA EN 13888

Super fine textured grout in powder form with smooth final surface. Practically waterproof and can be used inside swimming pools in cases where the use of epoxy grouts is not possible. It can be applied in very narrow joints (almost zero width) between rectified and glass mosaic tiles and in general applications of high aesthetic value.

Consumption: Depending on the application
Package: Plastic bags 5 kg
Pallet: 720 kg


  • NOVACOLOR GLASS cement-based grout is suitable for:
    •  grouting to:
      • all types of ceramic tiles
      • glass and marble mosaics
      • natural stones, marble, granite, agglomerates
    •  applications on horizontal and vertical surfaces such as:
      • external areas, facades, terraces, balconies, etc.
      • internal areas, wet areas like shower rooms and WC
      • underfloor heating systems
      • swimming pools and water tanks
    • heavy traffic floors such as shops, hotels, industrial sites, warehouses where resistance to chemical agents is not required
  • Form: powder
  • Joint thickness: 0-8 mm
  • POT life: approx. 30 - 45 minutes
  • Walkability: after 24 hours
  • Application temperature: from +5°C up to +35°C

Substrate preparation:

The joints should be dry and clean, free from grease, dust or loose materials. Adhesive residues should be removed from the joint before applying NOVACOLOR GLASS.

Preparation of the mix:

Mix the content of the plastic bag containing NOVACOLOR GLASS (5 kg) with 1.6 – 1.8 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 30 minutes. 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 of the mixture to the joints is made with rubber spatula diagonally in the direction of the joints to fill the depths and widths of the gaps. With the same tool and way, the excess material is removed from the surface of the tiles. Cleaning is done as long as the product is fresh using a well-moistened hard sponge with circular movements. During the cleaning process the sponge should be cleaned at regular intervals with plenty of water. Then the surface of the tiles is cleaned with a clean, soft and slightly damp sponge. At the end of the cleaning, the tile surface should be free from traces of grout, because after hardening the product can only be removed by mechanical means.


  • Protect the surface from rain and frost for the first 24 hours
  • During application, the minimum substrate and ambient temperature should be + 5°C and maximum + 35°C
  • For the adhesion and grouting of natural stones it is recommended to check the ease of cleaning and stability of natural stone shades
  • Do not use on porous surfaces (eg cotto)
  • Do not apply it to loose, fresh or on a substrate that has not matured sufficiently
  • Do not use it when there is water in joints or expansion joints
  • Do not use in joints bigger than 8 mm
  • Do not add cement, lime, gypsum or other binders or substances which may affect the mortar characteristics
  • Never exceed the maximum recommended quantity of mixing water
  • Avoid the presence of stagnant water in newly grouted joints. Permanent immersion in water takes place after 7 days
  • Application should be performed by professional skilled workers


Tools, buckets, tiles etc. can be cleaned with fresh and clean water as long as, NOVACOLOR GLASS is still fresh. After hardening occurs, cleaning can take place by mechanical means. Traces on tiles using ACID CLEAN.
