Cement based surfaces not sufficiently sound must be removed or, where possible, reinforced with Eco Prim PU 1K , Prosfas or Primer 3296 . Fissures in concrete substrates must be repaired with Eporip or Eporip Turbo . Dusty or very porous concrete surfaces must be treated with a coat of Eco Prim T , diluted with water 1:1, or Primer G , diluted with water 1:3 (both primers have very low emission of volatile organic compounds - EMICODE EC1 R Plus) in order to even out the absorbency of the substrate. Anhydrite screeds can be levelled with Ultraplan Eco only after the application of a coat of Eco Prim T or Primer G diluted with water 1:1. First apply a coat of undiluted Eco Prim T on ceramic or natural stone surfaces after the surface has been cleaned with detergents and mechanically abraded. Preparation of the mix Slowly pour a 20 kg bag of Ultraplan Eco 20 into a rust-free bucket containing 4.8-5 litres of clean potable grade water and mix with a low speed electric mixer fitted with a suitable mixing paddle to obtain an homogeneous, self-levelling lump free mix.Larger quanti- ties of Ultraplan Eco 20 can be prepared in mortar mixers. After allowing to settle for 2-3 minutes, the mix should be re-stirred and is then ready for use. The quantity of Ultraplan Eco 20 mixed must be used within 20-30 minutes (at a temperature of +23°C). Applying the mix Apply Ultraplan Eco 20 in a single layer of 1 to 10 mm thick with a large metal trowel or a squeegee, keeping the trowel slightly inclined to obtain the desired thickness. Ultraplan Eco 20 can also be applied with an automatic pressure pump. Due to its excellent self-levelling characteri- stic, Ultraplan Eco 20 immediately eliminates small imperfections (trowel marks, etc.). If a second layer of Ultraplan Eco 20 is required, it is recommended to apply it as soon as the first one is set to light foot traffic (approx. 3 hours at +23°C). Otherwise if the previous layer is completely dry, prime with Primer G diluted with 1:3 with water after first lightly abrading the surface of the previous layer or Eco Prim T (diluted 1:1 water). The levelling layer of Ultraplan Eco 20 will be ready to receive ceramic, natural stone (non- sensitive) fixed with adhesives after 12 hours at +23°C and resilient flooring, carpet, after 24 hours at +23°C (time can vary depending on the thickness of the levelling, the room temperature and humidity). Cleaning Prior to setting, Ultraplan Eco 20 can be cleaned and removed from tools and hands with water. CONSUMPTION 1.6 kg/m² per mm of thickness. PACKAGING Ultraplan Eco 20 is available in 20 kg bags.
STORAGE When stored in dry conditions in the original, unopened bags, Ultraplan Eco 20 has a shelf life of 12 months. If stored at high temperature and or high humidity conditions the shelf life may be reduced. A longer storage period could, determine a slower setting time of Ultraplan Eco 20 . However, the performance of the levelling layer in the long term is not significantly affected.
