WHERE TO USE Bonding all types and shapes of parquet. Some application examples Lignobond is used for bonding lamparquet, solid hardwood strips, planks and all types of parquet on cementitious screeds, anhydrite screeds, screeds made using Mapecem, Mapecem Pronto, Topcem, Topcem Pronto and similar products, old wooden, ceramic, marble, terrazzo etc. floors and metal sheets. Also suitable for heated substrates. TECHNICAL CHARACTERISTICS Lignobond is a two-component adhesive made from component A, an epoxy-polyurethane polymer, and component B, a special hardening paste. The consistency of the two pastes makes mixing much easier and helps to reduce the possibility of errors being made by users. When the two components are mixed together, they form a product with an even colour which is easy to apply with a notched trowel and which has excellent rib stability. Once hardened, approximately 24 hours after application at normal temperatures, Lignobond forms a tough film with high bond strength on any type of substrate, including those which are not absorbent (such as ceramic). RECOMMENDATIONS • Do not lay on screeds which are not protected against the risk of rising damp (always lay a vapour-proof sheath between the ground and the load-bearing screed). • Do not lay in rooms if the doors and windows have not been installed. • The humidity level in the screed must be according to current norms and standards. • Do not lay on asphalt which has not been sufficiently cured (minimum 15-20 days). • Do not lay if the temperature is lower than +10°C or higher than +30°C. • Only lay floors if the walls and ceiling in the room are completely dry. APPLICATION PROCEDURE Preparation of the substrate Substrates must be dry, flat, have good compressive and tensile strength and must be free of cracks, dust, loose portions, paint, wax, oil, rust and traces of gypsum or any other product which may compromise the bond. The maximum humidity level must be within the range prescribed by the manufacturer of the flooring material. Check the humidity content of the screed through its entire thickness with an electric or carbide hygrometer. Please note that this instrument supplies only an indication of the humidity content. Use MAPEi special hydraulic binders to make quick-drying, controlled-shrinkage screeds, such as Mapecem or Mapecem Pronto which allow floors to be laid after only 24 hours, or Topcem or Topcem Pronto pre-blended, ready-to-use mortar, which allow wood to be laid after 24 hours and 4 days respectively. Floating screeds installed on lightened sub-layers or insulating material and screeds laid directly on the ground must be cast on a vapour barrier to avoid humidity building up.

Hot-poured asphalt surfaces must have a consistency suitable to bear the foreseen loads. Floors must not be laid on bitumen with a low melting point or which may bleed oil. Concrete surfaces which are not sound enough must be removed or, where possible, consolidated with Prosfas, Primer EP, Primer MF and Primer MF EC Plus, Eco Prim PU 1K, Eco Prim PU 1K Turbo or Primer PU60 (see relative Technical Data Sheet). Cracks must be repaired with Eporip or Eporip Turbo (see relative Technical Data Sheet). If the flatness of the screed is not suitable for laying wood or if the screed is at the wrong...
