    Kiilto Highflex S2 DF is an almost white, non-sagging and very economical cementitious adhesive with lightweight filler for the setting of ceramic tiles, glass mosaic, as well as marble and stone. Good deformation properties. The new, low-dust technology significantly reduces the amount of dust during mixing. Suitable tiling substrates include, e.g., vinyl, paint, glazed tile, clinker and common aggregate surfaces as well as gypsum and fibre cement-board treated with Kiilto waterproofing membrane or Kiilto Kosteussulku moisture barrier. If using on hot surfaces, e.g., fireplaces or stove back panels (in private saunas), the maximum temperature is +100 °C. Consider the need for expansion joints; the tiling must be done at normal room temperature. Jointing can be done without a joint string. Underfloor heating must be switched off approx. 24 hours before starting the tiling work. Suitable for interior and exterior use.

    The surfaces to be tiled must be clean and free from dust. Remove water-soluble smoothing and levelling compounds. Dry and absorbent surfaces must be moistened (excl. boards). When tiling on vinyl, paint, tile and clinker substrates:

    – ensure that the surface is solid and strong for tiling
    – ensure that the surface to be tiled adheres properly to its own substrate
    – remove wax, grease and dirt with alkali detergent and rinse well
    After the surface has dried, sand it, if necessary, and then remove the sanding dust.

    When tiling on paint or PVC-coated steel sheets (e.g., pre-fabricated steel bathrooms):

    Any wax, grease or dirt must be removed from the surface, that is going to be tiled, with alkaline cleaner and rinsed thoroughly. After the surface has dried, sand it, if necessary, and then remove the sanding dust. Walls are primed with undiluted Kiilto Fix Primer (designed for vertical surfaces).
