  • The base surface must be dry and firm, all cracks and voids must be filled
  • Clean the surface from less persistent and/or separable layers
  • Particularly dense and/or smooth surfaces should be treated with an abrasive material
  • Surfaces must be primed with SAKRET UG primer (diluted in a ratio of 1:3)
  • Especially smooth concrete surfaces should be primed with SAKRET QG primer
  • Mix SAKRET FK Plus 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 the ripening time (~3 minutes) mix again
  • In one pass, cover with adhesive as much surface area as it is possible to cover with tiles in 20 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
  • 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)
