Minimum age of the substrate: - PCI Novoment M1 plus and/or PCI Novoment Z1 screed: 24 hours - PCI Novoment M3 plus and/or PCI Novoment Z3 screed: 3 days - Cement screed: 28 days - Concrete: 3 months The substrate must be structurally sound, clean and able to bear weight. Oil stains, residues which could impair adhesion and other spills must be thoroughly removed. The substrate must be plumb and flush in accordance with DIN 18 202 for the installation of ceramic tiles and flagstones. For the installation outdoors the substrate must have a slope of min. 1.5%. Plaster/render substrates must be released by the manufacturer for tiling and must be suitable for the intended purpose. Level small-surface irregular substrates with PCI Nanolight (up to 15 mm) or large surfaces alternatively with PCI Polycret 5/20, PCI Pericret, PCI Periplan or PCI Periplan Fein before tiling. Level timber floorboards with PCI Periplan Extra before the installation. Screeds on isolation layers or insulation layers tend to deform due to nonuniform dehydration (concave arching). To avoid excessive lowering of the edge at a later stage please contact the PCI Technical help-line prior to levelling or tiling. Prime very absorbent cement based substrates and aerated concrete with PCI Gisogrund, diluted 1 : 1 with water. Prime rough-ground anhydrite screeds, gypsum based flowable screeds, gypsum based substrates and mastic asphalt screeds in the interior with undiluted PCI Gisogrund. Prime magnesite screeds with PCI Gisogrund 404, diluted 1 : 1 with water. Prime cementitious substrates and gypsum-based substrates with PCI Gisogrund Rapid if time is a factor. Prime old ceramic tiles with PCI Gisogrund 303. Old PVC coverings must firmly bond to the substrate, any contamination such as grease etc. must be removed and the bond area sanded and primed with PCI Gisogrund 303. Metallic substrates in the interior such as steel and aluminium which are not exposed to moisture must be well supported to provide resistance to bending and oscillations. The substrate must be free from rust and grease. Prime metal with PCI Gisogrund 303. Wooden particle boards or OSB boards may have a moisture content of max. 10%. The wooden particle board (V100) or OSB board must be at least 25 mm thick when installed on floors and at least 19 mm when installed on walls. The particle boards must be screwed to the substructure at a distance between screws of max. 40 cm. The edge joint must be at least 8 mm wide. The butt joints of the particle boards must be glued. Prime wooden particle boards and OSB boards in dry areas with PCI Gisogrund 303, when exposed to moisture with PCI Wadian, and waterproof with PCI Lastogum. Allow primers to dry. Newly-laid cement screeds (heated and unheated) must not have a residual moisture content of more than 4%, anhydrite screeds and gypsum based screeds not more than 0.5% (measured with a CM meter).
