ADESIVER HERCULES Two-component epoxy-polyurethane hypoallergenic adhesive for wooden floors, free of solvents o o CD CO ADESIVER HERCULES is an odorless two-component adhesive for wooden floors with a very low sensitization level, free of solvents, water, isocyanic resins and epoxy resins with a MW <= 700. It has outstanding traction resistance, workability and coverage. Q_ O Destinations: Suitable for laying pre-finished and pre-calibred wooden floor as well as any other type of timber flooring including boards without having to prepare a bed of wood laths. Recommended for gluing onto heated subfloors. ■B Other uses: • Adhering of heat and sound insulating panels (cork, expanded polyurethane, rock-wool). § • Adhering of tiles on asbestos cement and chipboards. • Adhering of wood and building materials (ceramics, stoneware-marble tiles) on to metal bases. O w V> • Subfloor ° dry, clean, no-dust creating, not too rough. _c • Humidity of Subfloor ° 2,0% max with cement subfloors.

Proceed with the laying ensuring that the wood tiles are put together properly and gently hammered so as to make the adhesive adhere well to the whole surface. Perfect • adhesion to the subfloor is ensured if at least 65% of each wooden component is in direct contact with the adhesive. O • In presence of dust-creating and porous subfloors, we recommend to apply first one coat of PRYMER A, PRYMER PUB 77, PRYMER FAST 500, PRYMER 100 or PRYMER SF 1105 (see technical data sheets). I After the complete drying of the treatment proceed with the application of the adhesive. • In presence of humid subfloors, we recommend to apply first PRYMER PUB 77, PRYMER FAST 500, PRYMER 100, PRYMER SF 1105, PRYMER 100, PRYMER EPOX WETT or PRYMER WB 328 S (see technical data sheets). We do not recommend to dip the heads of the tiles into the ADESIVER HERCULES while laying them. If need be, dip the heads of the tiles into a vynilic (PARKETTKOLL) adhesive which has a very strong wood to wood adhesion avoiding also the typical "skidding" of the tiles. • If the wooden floor has to be laid on glassy surfaces (ceramic tiles, enamelled tiles, polished marble, etc.), remove and clean the surface from dust, grit, glue and waxes. Apply by cloth the adhesion promoter DILUENTE APA following the correct application time (see technical data sheet), than apply ADESIVER

HERCULES . The subsequent sanding can be operated after 3-4 days according to the atmospheric and the wooden floor's hygrometric conditions. In case of anhydrite subfloors, thoroughly sand using 24 or 36 grit sandpaper; remove dust and apply primer using PRYMER SF 1105 (do not dilute) or PRYMER PUB 77 with DILUENTE DMC 50 thinner at a ratio 70:30. Apply ADESIVER HERCULES and the next sanding should take place after 3-4 days, depending on the atmospheric conditions and humidity level of the wood species used.
