webercol superflex G – Grey C2TE S1 25 kg
Category: Stavebnictví / Lepidla na obklady
Colours: Gray
Description
webercol superflex G is a ready-mixed tile adhesive based on Portland cement, selected aggregates and specific additives that give it extreme flexibility. Classification C2TE S1 according to EN 12004: improved adhesion, reduced slip, extended open time and deformable. For all tile types, indoors and outdoors. Supplied in 25 kg bags.
Advantages
- Adhesive for all types of tiles
- High adhesion to the substrate without slipping
- For wall and floor coverings
- For indoor and outdoor use, including frost-exposed areas
- Deformable (S1) – absorbs movement of the substrate
Uses
- Indoor and outdoor tiling on flat substrates: concrete, self-levelling screeds and traditional mortar; also on cement-based external thermal insulation systems (ETICS).
- Laying ceramic, gres and porcelain tiles, mosaics, marble of various sizes and highly absorbent tiles on all substrates.
- Floors and walls in homes, shops and high-traffic commercial/industrial areas, including areas with very low temperatures and frost.
Not recommended
- Gypsum-based plasters, plastics, metal or wood.
- Wet substrates or areas with permanent water or very high humidity.

Substrate preparation
- Air and substrate temperature during application and curing must be between +5 °C and +30 °C.
- Substrates must be sound, dry, clean and level. On old substrates or traditional mortars, pre-treat with a suitable primer.
- Concrete, cement screeds and cement-lime mortars must be at least 28 days old with residual moisture ≤ 1.5%.
- Treat lime-cement substrates with weberprim deep and concrete surfaces with weberprim 813, following their technical data sheets.
Použití
- Pour the 25 kg bag slowly into 6.5–7 L of clean water and mix with a low-speed electric mixer (or trowel) until smooth and lump-free.
- Let the mix rest for 5 minutes, then stir it again briefly.
- Apply a thin first coat with the flat side of the trowel to remove dust and regulate substrate absorption, then comb the adhesive with a notched trowel (max. 10×10 mm) chosen for the tile size.
- Also apply adhesive to the back of the tile (back-buttering) to reach a minimum contact surface of 95%.
- Press the tiles into place with a slight sliding movement and tap them so the whole surface is in contact with the adhesive.
- Tiles can be adjusted within 30 minutes. If a skin forms on the adhesive, re-comb it with the notched trowel; if a tile was not placed in time, remove the adhesive and apply fresh material.
- Do not exceed 20 minutes between spreading the adhesive and placing the tile (optimal conditions). Use the mixed material within 120 minutes.
- Do not load the tiles for at least 24 hours. Grout after 24–48 hours.
Tools
Mixing: electric mixer and a clean bucket. Application: notched steel trowel.
Shelf life
12 months in the original sealed bag, stored on pallets in a dry place away from direct weather. Protect from frost.
Safety
- Hazardous component: Portland cement. Causes serious eye damage and skin irritation; may cause an allergic skin reaction and respiratory irritation.
- Wear protective gloves, protective clothing and eye/face protection. If in eyes: rinse carefully with water for several minutes, remove contact lenses if possible and call a poison centre or doctor. If on skin: wash with plenty of soap and water. If inhaled: move to fresh air.
- Soluble chromium (VI) content is below 0.0002% of the total dry cement weight.
Disposal
Do not dispose of unused product or empty packaging outside designated waste facilities. See the safety data sheet and local regulations.
All values refer to standard conditions: 20 °C and up to 65% relative humidity.
