MAPEI GmbH I Werk Weferlingen I Ultrabond Eco S9551K Emissionsgepruftes Bauproduktnach DIBt-Grundsatzen One-component, solvent-free, sililated polymer-based adhesive with a very low emission level of volatile organic compounds (EMICODE EC1 R Plus), for all types of parquet WHERE TO USE Bonding wooden parquet and all types and formats of pre-finished materials. Some application examples Ultrabond Eco S955 1K is used for bonding prefinished materials, lamparquet, slats, floor-boards and all types of parquet on: cementitious screeds, screeds made using Mapecem, Mapecem Pronto, Topcem, Topcem Pronto and similar products, old wooden floors, ceramic, marble, terrazzo, etc. and anhydrite screeds. It is also suitable for heated substrates. TECHNICAL CHARACTERISTICS Ultrabond Eco S955 1K is a one-component, sililated polymer-based adhesive without water, solvents, with a very low emission level of volatile organic compounds (EMiCoDE EC1 R Plus). It is manufactured according to a technology developed in MAPEI’s own research laboratories and has the following characteristics: • one-component, ready-to-use product; no catalyser is required, therefore no mixing. If stored correctly, remaining quantities of the product may be used again at a later date; • suitable for use by installers who are allergic to epoxy and epoxy-polyurethane products; • GEV certified, as a product with a very low emission level of volatile organic compounds (EMICODE EC1 R Plus); • compatible with Ultracoat and Ultracoat Oil water based varnishes and undercoats; • no hazard risks and risk and danger symbols; • easy to apply with excellent ridge holding; • 20-30% more yield compared with conventional two-component adhesives, thanks to its low viscosity and free-flowing properties when applied by trowel; • totally free of solvents; • easy to remove from hands and pre-finished elements. RECOMMENDATIONS • Before installation starts, doors and windows should be installed. • The humidity level in the screed must be compliant with that prescribed by the current standards for the installation of wood, and as indicated in the technical data sheet for the parquet. • If the substrate is not thoroughly dried, or if the residual humidity is higher than the level prescribed, we recommend the use of a suitable waterproofing primer, such as Eco Prim PU 1K, Primer MF, etc. • If there is a risk of rising damp, a vapour barrier must be installed before laying the screed. • Do not use Ultrabond Eco S955 1K if the temperature is lower than +10°C or higher than +35°C. • When transported over long distances, thermally insulated containers may be required. APPLICATION PROCEDURE Preparation of the substrate The substrate must be checked carefully to assess its condition, and to prepare it for laying parquet.

TECHNICAL DATA (typical values) Easy opening of the bucket PRODUCT IDENTITY • Cementitious screeds: must be well cured, dry, flat and mechanically strong. The surface must be free of dust, loose parts, oil, paint, etc. The level of humidity in the screed must be measured using a carbide hygrometer. To solve problems of residual humidity levels higher than those prescribed for laying, wait until the screed is dry, or apply a suitable waterproofing primer, such as Eco Prim PU 1K, Primer MF, Primer EP, Primer PU60, Triblock P, etc. Cracks in the substrate must be repaired beforehand with a product...

• Wooden floors: make sure wooden floorboards are rigidly fixed to the substrate. Remove old paint or wax with sandpaper down to the bear wood, and remove all dust. The adhesive may then be applied. • Anhydrite substrates: check and follow the instructions of the manufacturer of the screed. Always check if the screed should be sanded and primed. MAPEI recommends sanding and priming with Eco Prim PU 1K, Eco Prim PU 1K Turbo, Primer MF and Primer MF EC Plus. MAPEI declines all responsibilities if all the screed manufacturer’s recommendations have not been followed. In case of doubt do not hesitate...
