One-component, solvent free, ready-to-use elastic polyurethane adhesive with an extremely low emission level of volatile organic compounds (VOC), for pre-finished, multi-layered and traditional jointed solid wood parquet WHERE TO USE Bonding all size and formats of jointed, pre-finished solid wood parquet with a ply backing. We advise against laying varnished, pre-finished solid wood in the lower part or traditional solid parquet without tongue and groove. Some application examples Ultrabond P990 1K is used for bonding pre-finished, lamparquet, pin-wheels and jointed planks on: cementitious screeds; screeds made using Mapecem, Mapecem Pronto, Topcem, Topcem Pronto and similar products; old wooden floors; ceramic, marble, etc.; anhydrite screeds. Suitable for heated floors. TECHNICAL CHARACTERISTICS Ultrabond P990 1K is a moisture curing, polyurethane resin-based adhesive, produced using technology developed in MAPEI’s own laboratories, with the following characteristics: • ready-to-use one-component product, does not require catalyser and successive mixing. If stored correctly, leftover quantities of the product may be used at a later date; • suitable for floor-layers allergic to epoxy-polyurethane products; • easy to apply, even at low temperatures; • 30% higher yield compared with conventional two-component products, thanks to the low viscosity and easy to trowel of the adhesive when applied by trowel, even at low temperatures; • excellent rib stability and excellent buttering on the back of tiles; • extremely low expansion, parquet remains flat after laying; • does not contain solvents or substances which give off unpleasant odours; • low environmental impact, certified by the GEV (EC1 R Plus) Institut as a product with extremely low emission levels of volatile organic compounds. RECOMMENDATIONS • Before laying, make sure all rooms have suitable windows or other sealing systems. • The humidity level in the screed must be according to current norms and standards. • If the substrate is not completely dry, or if the humidity is higher than the recommended level, we recommend applying a coat of suitable waterproofing primer, such as Eco Prim PU 1K, Primer MF, Primer MF EC Plus, etc. • If there is a risk of rising damp, a vapour barrier must be laid before installing the screed. • The humidity level in the wood must be according to current norms and standards. • Do not lay if the temperature is lower than +10°C or higher than +35°C.

Laying wood • Only lay floors if the walls and floors in the room are completely dry. • In particularly dry weather, the hardening time of the product is longer. • Do not let the product come into contact with fresh two-component epoxy-primer, otherwise it will deteriorate. • Non-absorbent surfaces such as ceramic and marble must be sanded or cleaned and then treated with Primer M. • Apply a coat Primer M on metallic surfaces. APPLICATION PROCEDURE Preparation of the substrate The condition of the substrate must be carefully checked to make it is suitable for laying parquet. • Cementitious screeds:...
