![[Translate to English:]](/fileadmin/kiesel/bilder/produkte/K_ServolightS1SuperTec_S.png "[Translate to English:]")
New generation of cement-based flexible thin set mortar with extended coverage, excellent bonding strength and easy handling according to EN 12 004 C2 TE-S1. 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 fiber board, sheet rock, 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 S1 SuperTec can also be used for under water installations (swimming pools), even of glas mosaic and can be used to fill holes and level substrates up to 3/4" (15 mm) thickness.
Meets and exceeds german industrial standard for flexible tile adhesive "Richtlinie für Flexmörtel" and ANSI A 118.4.
The substrate must be ready for installation, dry, clean and has to have enough load-bearing. If installation occurs on shrinking substrates, frequent expansion joints should be included in the layout. In exterior areas apply a contact layer of adhesive mortar and let it set. Prime absorbent substrates in interior areas with Okatmos® GG, Okatmos® UG 30 or Okatmos® DSG. Allow drying time over calcium sulfate screed or prime with Okamul PU-V schnell. Clean non-absorbent substrates like Terrazzo, ceramic tiles or existing sound and load bearing PVC-coverings with a suitable alcaline cleaner, grind and clean with heavy duty vaccum cleaner. Then prime with Okatmos® UG 30/Okatmos® DSG. Metal surfaces like steel, galvanized steel or aluminum in interior applications have to be form stable (no vibration or flexural stress) and rust free. Remove grease with aceton and prime with Okatmos® UG 30/Okatmos® DSG. Wood substrates have to be dry (moisture content less than 10 %) and thoroughly fixed to the substrate (minimum spacing between screws 15" (40 cm)). Minimum thickness on floors 1" (25 mm), 3/4" (19 mm) on walls. Tongue and groove have to be glued. Allow particle board primed with Okatmos® UG 30/Okatmos® DSG to dry for at least 24 hours.
In exterior areas, prime mineral substrates with Okatmos® UG 30 or Okatmos® DSG, on old coatings on horizontal surfaces prime with Okatmos® UG 30 or Okatmos® DSG and apply bonded waterproofing Servoflex DMS 1K-schnell SuperTec or Servoflex DMS 1K Plus SuperTec.
Mix Servolight S1 SuperTec with clean water to a smooth texture. 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 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 approx. 25 minutes.
