Specifications: EN 12004 C2TE-S1Description: High performance, deformable, cementitious, acrylic adhesive for tiles,with extended open time and no vertical slip.Applications: Suitable fori nterior and exterior bonding of every type and size ceramic and porcelain tiles, on floor and walls.Product Identity Appearance: cement-based powder Colour: Grey, White Storage: 9 months in the original packaging, in a dry place Particle size: 0-0.8mmApplication Data Mixing Ratio: 25kg in 8L water Pot life: 4h /mix every 1h, at 23ºC & 50% RH Open time: 30 min at 23ºC & 50% RH Consumption: 2-5 kg/m2 depending on use and surface Application temperature: +5 ºC - +35 ºC Grouting: 24 h * * The time for grouting or for final use may vary depending on weather conditions, application thickness and the porosity of the substrate. Adhesion Strength≥ 1 Ν/mm2 according ΕΝ 12004 0.8 Ν/mm2 30 min open time 2.1 Ν/mm2 after 28 days 1.5 Ν/mm2 after water immersion 1.9 Ν/mm2 after heat ageing 2.0 Ν/mm2 after freeze/thaw cycles Slip 0.3 mm Deformability: 3.3 mm Temperature when in use: -30ºC-+90ºC ApplicationWith the flat side of the trowel apply the adhesive to the substrate, pressing firmly to work into surface. Comb on additional adhesive with the notched side. Use the proper sized notched trowel to insure full bedding of the tile. Spread as much adhesive as can be covered with tiles in 25-30 minutes. Place tiles into wet, sticky adhesive and beat in using a beating block and rubber mallet to imbed tiles and adjust level. If mortar is skinned over (not sticky), remove and replace with fresh mortar. Substrates Preparation Substrates must be mechanically sound, free of loose particles, grease, oil or other materials that reduce the adhesion. The substrate must be stable without cracks and have already completed the curing period of hygrometric shrinkage. Uneven sections must be corrected with suitable smoothing and finishing product. Preparing the mix- Application Pour the material to a bucket of clean water mixing constantly with a low speed (400 rpm) electric mixer until a creamy consistency is achieved. Allow mixture settle for 5 minutes and remix prior the application. Attention! Additional water will make your mixture sloppy and may cause negative results on final strength. The open time of ALFAKOL 6*, in normal conditions of temperature and humidity is 30 minutes. Unfavourable environmental conditions (strong sunlight, drying wind, high temperature as well as highly absorbent substrate), could drastically reduce this time to a few minutes.
