Coating System 1- Broadcast floor: (3-4mm layer thickness) Structure: Priming: (for normally absorbent surfaces) Sikafloor® -156 0.3 - 0.5 kg/m2 Base layer: Sikafloor® -261 (A+B+C) 2.8 - 3.8 kg/m2 Broadcasting: quartz sand (0.3-0.9 mm) approx. 3 - 4 kg/m2 ® Topcoat: Sikafloor -261 (A+B) approx. 0.6 kg/m2 Mixing ratio: Comp. (A): comp. (B): comp. (C) = 10: 3: 13 (parts by weight) Comp. (C) = quartz sand (0.08-0.2 mm) Mixing: Stir component (A) well. Add component (B) in the right mixing ratio and mix by means of an electric stirrer (approx. 300-400 rpm). Mixing time at least 3 minutes until a homogeneous mixture is achieved. Fill mixed material into a clean container and mix again quickly Application: Apply base layer evenly with a toothed trowel (6-8 mm notches) and detrain any entrapped air with a spiked roller. Broadcast the homogeneous base layer with sand in excess. As soon as the layer is ready for foot traffic the sand is brushed off, the surface slightly overworked with a grinding machine, vacuum cleaned and subsequently sealed with a short pile roller, a straight trowel or a squeegee. 2. Self-leveling floor: (1.6-3.0 mm layer thickness) Structure: Primer: Sikafloor® -156 0.3 - 0.6 kg/m2 ® Self-leveling floor: Sikafloor -261 (A+B+C) 2.8 - 5.1 kg/m2 2 Consumption: 1.7 kg/m mixture per mm layer thickness Mixing ratio: Comp. (A): comp. (B): comp. (C) = 10:3:13 (parts by weight) Comp. (C) = quartz sand (0.08-0.2 mm) Mixing: Stir Component (A) well. Add component (B) in the right mixing ratio and mix by means of an electric stirrer (approx. 300-400 rpm). Mixing time at least 3 minutes until a homogeneous mixture is achieved. Fill mixed material into a clean container and mix again quickly. Application: Apply the self-leveling floor evenly with a toothed trowel (6-8 mm notches) and detrain any entrapped air immediately with a spiked roller. Self-leveling coating 1 mm: Mixing ratio: 1pbw Sikafloor® –261 (A+B) 0.4 pbw Sikafloor® filler 1 Consumption: 1.6 kg/m2 mixture per mm Layer thickness 3. Mortar screed: (approx. 8 mm layer thickness) Structure: Primer: Sikafloor® -156 (thixo) approx.0.3 – 0.6 kg/m2 ® Screed: Sikafloor -261 (A+B+C) approx.17 kg/m2 Mixing ratio: Comp (A) : comp. (B) = 10 : 3 (parts by weight) Comp. (A + B): comp. (C) = 1: 7 (parts by weight) Comp. (C) aggregate In practice the following sand mixtures proved to be suitable (granulometry for a layer thickness of approx. 8 mm): 33 pbw quartz sand 0.1-0.5 mm 33 pbw quartz sand 0.4-0.7 mm 33 pbw quartz sand 1.0-2.0 mm The largest grain size should be approx. 1/3 of layer thickness. Depending on grain shape and application temperature the aggregates must be matched to each other by practical trials. Factory made sand mixtures (Sikadur® -506) tend to segregate during transport, therefore use whole bags only. Sikafloor® -261

Mixing: Stir component (A) well. Add component (B) in the right mixing ratio and mix by means of an electric stirrer (approx. 300-400 rpm). Mixing time at least 3 minutes until a homogeneous mixture is achieved. Fill mixed material into a clean container and mix again quickly. Application: Apply 10 kg Sikafloor® -156 primer with 0.2 kg Extender T and 2.1 kg quartz floor. Apply mortar layer evenly on the still tacky, thixotropic primer, using levelling boards and guide rails. Compact and smoothen with a trowel or Teflon coated power float. 4. Coating: (high-build) System (0.3 – 0.4 mm): Sikafloor® -261 (A+B) approx. 0.4 – 0.5 kg/m2 System (0.6 - 0.8 mm): ® approx. 0.4 – 0.5 kg/m2 1. layer: Sikatloor -261 (A+B) 2. layer: Sikatloor® -261 (A+B) approx. 0.4 – 0.5 kg/m2 Mixing ratio: Comp. (A) : comp. (B) =10 : 3 (parts by weight) Mixing: Stir component (A) well. Add component (B) in the right mixing ratio and mix by means of an electric stirrer (approx. 300-400 rpm) Mixing time at least 3 minutes until a homogeneous mixture is achieved. Fill mixed material into a clean container and mix again quickly. Application: Both systems are applied evenly with a short piled lamb skin roller. 5. Textured coating (approx. 0.8 mm layer thickness) System: 1st layer: Sikafloor® -261 (A+B) approx. 0.4 – 0.5 kg/m2 2nd layer: Sikafloor® -261 (Thixotroped with extender T) approx. 0.5 kg/m2 Mixing ratio: Comp. (A) : comp.(B) = 10 : 3 (parts by weight) Mix Extender T in comp. (B). (Dosage of Extender T = 1.0 – 1.5 % of Comp. (A) + Comp. (B) Mixing Stir component (A) well. Add component (B) in the right mixing ratio and mix by means of an electric stirrer (approx. 300-400 rpm). Mixing time at least 3 minutes until a homogeneous mixture is achieved. Fill mixed material into a clean container and mix again quickly. Application st nd Apply the 1 layer evenly with a short piled lamb skin roller. For the 2 layer use thixotropied binder and apply with a short piled Iamb skin roller and finish with a textured roller in order to achieve a uniform texture. 6. Application on green/fresh and damp concrete: For the application of the before-mentioned coating systems on green/fresh and damp substrates the following structures are necessary: Horizontal smooth surfaces: Primer: Sikafloor® -155 W approx.0.2 - 0.4 kg/m2 ® Levelling layer: Sikatloor -81 EpoCem approx. 4.0 kg/m2 Horizontal broadcasts surfaces: Primer: Sika Repair® -Sikafloor® EpoCem Modul approx. 0.2-0.3 kg/m2 Broadcast layer Sikafloor® -81 EpoCem approx. 5.5 kg/m2 broadcasted with quartzsand in excess Slopes: Smoothening with Sikagard® -720 EpoCem Skirtings and coves: ® Filling with Sikagard -720 EpoCem extended with quartzsand (0.08 - 0.2 mm)
