Fixing large formats
- SCREED
Cementitious mortar screed at least 4 cm thick made of quickly evaporating, normally setting binder such as KRONOS by Technokolla and siliceous aggregates with 0 to 8 mm continuous grain size, reinforced with synthetic fibers and/or metal netting. Screed resistance must be 28-30 N/mm2 after 28 days, while it must be possible to begin fixing the ceramic, marble and natural stone tiles 24-48 hours after application. Screed reinforcing with fibers such as FS-18 by Technokolla and/or 5x5 cm mesh galvanized metal netting with 2 mm diameter wire installed at 1/3rd of the screed thickness.
Dosage for 1 m3 of 0 to 8 mm aggregate:
250 kg KRONOS 150 l. water 1 kg FS-18 fibers
- FLOORING
Flooring and skirting in large slabs of porcelain stoneware or natural stone fixed to a KRONOS screed with highly flexible cementitious adhesive such as TECHNOSTAR, conforming to European standards EN 12004 C2TE, EN 12002 S1 or with highly flexible full-bed cementitious adhesive such as TECHNOMAX, conforming to European standard EN 12004 C2E, or TECHNORAP-2, conforming to European standards EN 12004 C2FT, EN 12002 S1 for large formats, all by Technokolla. 4-5 mm gaps grouted with low modulus cementitious grouting such as TECHNOCOLORS by Technokolla, conforming to European standard EN 13888 CG2. Expansion joints sealed with ACESIL-310 by Technokolla, after synthetic cord has been positioned. NEUSIL must be applied in the case of stone floors. To proceed in the correct way, it is advisable to apply the silicone before cementitious grouting.
Amount of adhesive required:
5.5-7 kg/m2 Amount of grouting required:
0.2 kg/m2 (60x60 cm format, 4 mm gaps)
