FFKs / Fast-hardening tile adhesive with improved properties (grey, class C2 FT)

  • For tiling on plasterboard, old tiles and on waterproofing SAKRET OAD ELASTIC
  • For ceramic and stone mass tiles, stone facing plates, fireplace facing tiles, clinker tiles and plates
  • Can be used on heated floors
  • Suitable for repairs and quick results
  • Frost and moisture resistant


Surface preparation

  • The base must be dry and firm, all cracks and voids must be filled
  • Clean the base from less persistent and/or separable layers
  • Especially dense and/or smooth substrates must be scraped
  • Surfaces must be primed with SAKRET UG primer (diluted in the ratio 1:3). Especially smooth concrete surfaces should be primed with SAKRET QG primer


  • Mix SAKRET FFKs in a clean container with cold water until a homogeneous mass without lumps is formed
  • It is recommended to use a mixer with 600 turns per minute
  • After ripening time ~3 min. mix again
  • In one pass, cover with adhesive as large a surface area as it is possible to cover with tiles in 10 min. at a time
  • Deformation joints must not be filled with tile adhesive
  • Do not perform tiling work in direct sunlight, drafts and on wet surfaces
  • Hardened tile adhesive can only be removed mechanically


  • The technical data refers to a temperature of +20°C and 50% relative air humidity. Lower temperature increases, higher - decreases the specified values
  • During the hardening phase, protect the tile adhesive from the sun, drafts, frost and excessively high temperatures (>25°C)
  • Contains cement, reacts alkaline
  • Protect skin and eyes, follow technical instructions. If the mortar gets into the eyes, rinse with a large amount of water, if necessary, consult a doctor
  • Protect the packaging from weather conditions, store on wooden pallets, in a cool and dry place, cover torn packaging immediately


  • 5 kg / paper bags / 200 bags per pallet
  • 25 kg / paper bags / 48 bags on a pallet
  • 1,000 kg / Big-Bag packaging / pre-ordered
  • 10,000 kg - 20,000 kg / mobile transport silos
