![[Translate to English:]](/fileadmin/kiesel/bilder/produkte/K_ServoflexKPlusSuperTec_S_05.png "[Translate to English:]")
Extremely sag resistant, flexible cement-based thin set mortar for interior, exterior and submerged ceramic and quarry tile installations, porcelain stoneware, porcelain and glass mosaic, clinker and brick tile according to EN 12 004 C2FTE-S1. Secure curing even with colder temperatures and dense materials.
Because of its high polymer content the adhesive can also be used over substrates such as in situ concrete (at least 3 months old), 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. Servoflex K-Plus SuperTec can also be used for submerged applications (swimming pools) and as bonding support for natural stone and porcelain stoneware installations in mortar beds. For this purpose back-buttering method is required. After back-buttering method slide the tile it into the thick bed mortar.
The substrate must be ready for installation, dry, clean and load bearing. If installation occurs on shrinking substrates frequent expansion joints should be included in the layout.
Prime absorbent substrates in interior areas with Okatmos® GG or Okatmos® UG 30. Allow a drying time of at least 24 hours over calcium sulfate screed and prime with Okapox GF for mortar layers thicker than 3/16" (5 mm) or apply leveling layer with Servoflex K-Plus SuperTec.
Prime non-absorbent substrates with Okatmos® UG 30. In exterior areas apply a contact layer of adhesive mortar and let it set.
Mix Servoflex K-Plus SuperTec with clean water to a smooth texture. 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 25 minutes.
