The most important properties of the product: - Significantly reduced dusting of the product - For stoneware, non-absorbent stone and clinker - For damp and wet rooms and outside - Medium-layer, up to 15 mm - Reduced drainage - Frost-waterproof Product application: Weber ZP414 adhesive mortar was produced in an innovative technology reducing dusting during pouring and mixing, therefore it is especially recommended for working in confined spaces. Significant reduction of dust from cement dust and air dust, improves the comfort of work in a noticeable way and shortens the time of cleaning works. Weber ZP414 adhesive can be used indoors and outdoors in residential construction and on substrates with increased usable load, e.g. commercial and industrial floors. It is intended for laying glazed and terracotta tiles, porcelain tiles and non-absorbent stone and clinker on walls and floors. The substrate for the cladding can be: - concrete - cement and cement-lime plaster - gypsum plaster - gypsum-cardboard and chip-cement boards - cement and anhydrite screed - OSB boards - old paint coatings - existing ceramic cladding, terrazzo - underfloor heating - boards thermal insulation - raw surfaces made of small-size elements: brick, blocks, concrete, ceramic, silicate and other similar building materials. - The mortar can be used for leveling the surfaces under the tiles to be laid (one layer is 2-15 mm thick) 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. Recommendations: Particularly recommended for work in closed rooms - non-dusting product. For use on surfaces with increased usable load - staircases, lobbies, corridors in humid and wet areas - kitchens, bathrooms, showers, laundries and outdoors - balconies, terraces, plinths. Non-appropriate product for fixing ceramic tiles on the facade. For fixing the tiles on the facade in the thermal insulation system, we recommend using the Weber ZP418 adhesive mortar. Technical data: Mixing ratio: 7.0-7.5L / 25 kg Maturing time: 5 min Open time: 30 min Correction time: 20 min Ready to use time: (temperature approx. 20 ° C) 4 h Minimum thickness: 2 mm Maximum layer thickness: 15 mm Runoff: 0.5 mm Adhesion: 1.0 N / mm2 Full strength: after 3 days Pedestrian traffic / grouting: after 24 hours Consumption: 2-6 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.
