Adhesive for the installation of all types of wood.
ULTRABOND P990 1K – Mapei and the Innovative Solution for Wood Flooring Installations ULTRABOND P990 1K is an extremely innovative polyurethane one-component adhesive, ready-to-use, elastic and solvent-free, for all types of wooden flooring and laminates. Its three main characteristics make the product a unique innovation into the UK Wood Flooring marketplace: it is a one-component polyurethane, it has an absence of solvents which allows vastly reduced reactions for installers, and the innovative packaging that virtually eliminates unreasonable waste allowing total use of the product.
ULTRABOND P990 1K is sold in a package composed of an aluminium bag in a plastic bucket. When installation works are finished, to preserve the unused product it is the bag can be re-sealed after letting out as much air as possible to prevent the formation of a surface film. Its range of application includes the bonding of wooden flooring, pre-finished wood or laminates of any size and type; the installation may be performed on: cementitious screeds, MAPECEM, TOPCEM, TOPCEM PRONTO and the like, existing wood flooring, ceramic tiles, marble terrazzo tiles etc, anhydrite screeds. It is also suitable for underfloor heating systems.
Technical Characteristics ULTRABOND P990 1K is an adhesive based on hydro-hardening polyurethane resin prepared according to technology developed in the Mapei laboratories. It is a ready-to-use one-component product that does not require the addition of a hardener and subsequent mixing. The unused product, if stored correctly, can be re-used for other applications. It is hypo-allergenic, and can be used by installers that are allergic to epoxy-polyurethane products. It is easy to apply, even at low temperatures, and has a yield 20-30% greater than that of the traditional two-component products, thanks to its low viscosity and the fluidity of the adhesive under the trowel even at low temperatures.
It should also be stressed that it has excellent rib stability, even with high temperatures, that makes the adjustment of the wood during installation easier. The expansion of the adhesive does not modify the flatness of the installed wooden flooring. The comfort aspect is also important: the absence of solvents and of substances that can emit unpleasant odours guarantees a comfortable and convenient use by installers. The adhesive’s sound absorption abilities, forming an elastic layer that reduces trampling noise, is also a benefit for the end consumer.
Application Procedure As a first step it is necessary to carefully check the substrate to verify its condition, and to make it suitable for the installation of parquet. In the case of cementitious screeds, these must be cured, dry, flat and mechanically sound. The application surface must be free of dust, loose particles, oil residues, paints etc. The substrates that are not solid enough should be removed or, where possible, consolidated with a primer such as PROSFAS, PRIMER EP or PRIMER PU60. Cracks can be repaired with products such as EPORIP, EPORIP TURBO and EPOJET. Excessively rough or uneven surfaces can be smoothed with a levelling compound with high mechanical strength, such as FIBERPLAN, ULTRAPLAN, ULTRAPLAN MAXI or NIVORAPID and others, to be chosen in relation to the thickness required.
For existing floorings, such as ceramic tiles and marble, it is necessary that these are clean with any grease removed carefully prior to any bonding. No adhesion promoter should be applied because the two products are not compatible. In situations where existing wooden flooring is resent, it is necessary to check that the existing floor boards are well secured to the substrate. Use abrasive paper to remove the layer of wax or varnish until the wood is clean and vacuum remaining dust – fixing can then proceed. In the case of anhydrite substrates, after sanding down and vacuuming up remaining dust, apply PRIMER MF and proceed with the installation after 3-4 hours, but no more than 12 hours. Alternatively, overlay with fresh sand and the day after, upon complete hardening, vacuum up the excess unattached sand and then proceed to the bonding. Floors are set to light foot traffic after approximately 12 hours.
