A new generation of cement-based flexible, acrylic polymer, thin-set mortar with extended coverage, excellent bonding strength and easy handling according to EN 12 004 C2 TE-S1 and ANSI A 118.4.. For almost all substrates in interior and exterior applications. For almost all covering materials, including ceramic and quarry tile installations, porcelain stoneware, porcelain and glass mosaic, clinker and brick tile. Because of its high polymer content, the adhesive can also be used over substrates such as in-situ concrete (at least 3 months old), prefabricated concrete elements, gypsum fiberboard, sheetrock, heated screed (follow corresponding regulations and data sheets), poured mastic asphalt and autoclaved aerated concrete (AAC) as well as balconies, patios and exterior walls. Servolight can also be used for underwater installations (swimming pools), even of glass mosaic and can be used to fill holes and level substrates up to ¾“ (15 mm) thickness.
The substrate must be ready for use, clean and stable. Prime absorbent surfaces with Okatmos® DSG or Okatmos® UG 30 indoors. Prime calcium sulphate screeds with Okatmos® DSG or Okapox GF when exciding mortar thickness over 5 mm/3/16”.
Expansion joints shall be provided through the tile work from all construction or expansion joints in the substrate. Follow recent TTMAC and ANSI specification A108.01-3.7 “Requirements for Movement Joints: Preparations by Other Trades” or Tile Council of North America (TCNA) detail EJ-171 “Movement Joints—Vertical & Horizontal.” Do not cover expansion joints with mortar.
Thoroughly clean non-absorbent substrates, e.g. Terrazzo, old ceramic coverings with Okamul GR Basic Cleaner, allow to dry and prime with Okatmos® DSG or Okatmos® UG 30*.
Thoroughly clean old, firmly adhering homogeneous VCT coverings in a dry indoor area with Okamul GR Basic Cleaner, allow to dry, sand and vacuum with an industrial vacuum cleaner. Then prime with Okatmos® UG 30 or Okatmos® DSG. Check local building laws/recommendations when dealing with asbestos-based VCT.
Mix Servolight with clean, cool water to a smooth texture using a proper amount of water. If necessary, adjust mortar consistency by adding small quantities of water. Allow mixture to slake for approx. 5 minutes and stir again. Use appropriate notched trowel (see table) to apply mortar onto a substrate, slide the covering material into the adhesive bed within 30 minutes and press tightly. Depending on the absorbency of the substrate/covering corrections can be made within 25 minutes.
