The most important properties of the product: - interior and exterior - maximum tile size: 33.3 x 33.3 cm - reduced runoff - good adhesion to tiles and the substrate - waterproof and frost-resistant Product application: Weber ZP412 adhesive can be used indoors and outdoors. outdoors in residential construction, e.g. in kitchens, bathrooms. It is intended for laying glaze and terracotta tiles (water absorption> 3%) with sizes up to 33.3 x 33.3 cm, on walls and floors. The base for cladding can be: - concrete - cement and cement-lime plaster - cement screed raw surfaces made of fine-sized elements: brick, blocks, concrete, ceramic, silicate and other building materials of this type. Weber ZP412 cannot be used on gypsum surfaces. The mortar can be used for leveling the surfaces under the tiles to be laid on the walls (one layer thickness is 2-5 mm) and for building small elements, eg bathtub or shower tray covers, etc. The mortar can be used outdoors, but frost-resistant tiles should be used. Technical data: Mixing ratio 6.5-7.5L / 25 kg Maturing time 5 min Open time 20 min Correction time 20 min Ready to use time (temperature approx. 20 ° C) 3 h Minimum layer thickness 2 mm Maximum layer thickness 5 mm Runoff? 0.5 mm Adhesion? 0.5 N / mm2 Full strength after 3 days Foot traffic / grouting after 24 hours Consumption 2-5 kg / m2 IMPORTANT! Classes of adhesives for tiles Adhesives are classified on the basis of the European standard PN EN 12004. According to it, adhesive mortars are divided by type and class. There are types of adhesives (due to their chemical composition): C - cement, D - dispersion, R - reactive (based on synthetic resins: polyurethane and epoxy). Due to technical parameters, the classes of adhesives are: 1 - normally binding, 2 - with enhanced parameters. Due to additional requirements, the classes of adhesives are: F - fast-setting, T - with reduced flow, E - with extended open time. Additionally, according to the PN EN 12002 standard, adhesive mortars can be divided according to their transverse deformation into: S1 - deformable adhesives - from 2.5 to 5 mm, S2 - highly deformable adhesives - over 5 mm. Thus, mortar marked with C2 symbol has better adhesion properties than ordinary class C1 mortars. The adhesive marked C2 S1 is additionally characterized by deformability, and C2 S2 - high deformability. The C2 TE mortar is a quick-setting cementitious adhesive with increased adhesion and reduced flow, C2 FT S1 - a quick-setting deformable cement adhesive with increased adhesion and reduced flow.
