Fixing composite marbles
- 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 composite marble flooring 24-48 hours after casting. 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 slabs of composite marble fixed on a KRONOS screed with highly flexible cementitious adhesive suitable for composite marble, marble and natural stone, such as TECHNORAP-2 or epoxypolyurethane adhesive such as ALL 9000 by Technokolla, in accordance with European standards EN 12004 C2FT, EN 12002 C2S1 (Technorap-2) and R2T (ALL 9000). 4-5 mm gaps grouted with low modulus cementitious grouting such as TECHNOCOLORS by Technokolla, conforming to European standard EN 13888 CG2. Expansion joints every 12 m2 sealed with NEUSIL by Technokolla after the substrate has been prepared with PRIMERSIL primer (only for tiles fixed outdoors) applied with a brush throughout the entire depth of the joint and with synthetic cord positioned successively. To proceed in the correct way, it is advisable to apply the silicone before cementitious grouting. Amount of adhesive required: from 4 kg/m2 (the amount varies depending on the format of the slabs). Amount of grouting required: 0.35 kg/m2 (30x30 cm format, 4 mm gaps) |
