Where to use
Bonding pre-finished, multi-layered parquet, pre-assembled work-tops and all shapes and types of multi-layered elements on any kind of substrate. Particularly suitable for heated substrates. Odourless and completely free of solvents and free amines, may be used by installers allergic to epoxy-polyurethane products.
Some application examples
Ultrabond P980 is used for bonding pre-finished, multi-layered parquet elements 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. Also suitable for heating substrates.
Ultrabond P980 is a one-component, solvent-free polyurethane adhesive with no amines or epoxy resin, with a very low emission level of volatile organic compounds (EMICODE EC1 R Plus). The product has been developed in Mapei’s own research laboratories and has the following characteristics:
Completely free of solvents and amines.
GEV certified as a product with a very low emission level of volatile organic compounds (EMICODE EC1 R Plus).
one-component, supplied ready to use. If stored correctly, leftover quantities of the product may be used at a later date.
May also be used by floor-layers allergic to epoxy and epoxy-polyurethane products.
20-30% higher yield compared with conventional two-component products.
Excellent straight-line hold.
Before laying, make sure all rooms have windows or other suitable sealing systems.
The level of humidity in the screed must be according to current norms and regulations for laying wood, indicated in the Technical Data Sheet of the parquet.
If the substrate is not completely dry, or if the humidity is higher than the required level, we recommend applying a coat of 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 laid before installing the screed.
Do not use Ultrabond P980 at temperatures lower than +10°C or higher than +25°C.
Only lay floors if the walls and floors in the room are completely dry.
Preparing the substrate
The condition of the substrate must be carefully checked to make sure it is suitable for laying parquet. Cementitious screeds must be well-cured, dry, flat and strong. Use Mapei special hydraulic binders to make quick-drying, controlled-shrinkage screeds such as Mapecem, which allows floors to be laid after only 24 hours, or Topcem after 4 days. Other suitable products are Topcem Pronto or Mapecem Pronto ready-to-use, pre-blended mortars which allow wood to be laid after 4 days and after 24 hours, respectively. If lightened layers or insulating layers are present on screeds installed directly on the ground, lay a suitable vapour barrier to avoid rising damp. The surface must be free of dust, crumbly portions, traces of oil, paint, etc. The level of humidity in the screed must be measured with a carbide hygrometer. If the level of humidity is higher than the recommended limit for laying, wait until the screed is dry. As an alternative, if the humidity percentages are compatible with the ones described in the relevant products’ technical data sheet, a special waterproofing primer may be applied, such as Eco Prim PU 1K, Eco Prim PU 1K Turbo, Primer MF, Primer MF EC Plus or Triblock P. Repair any cracks present in the screed with products such as Eporip, Eporip Turbo, Epojet, etc.E xcessively rough or uneven surfaces may be smoothed over with a high-strength smoothing and levelling compound such as Fiberplan, Ultraplan, Ultraplan Maxi, Nivorapid, etc., according to the thickness to be applied. Laying may then be carried out once dry (see relative Technical Data Sheet).
Old ceramic, marble, etc.: floors must be thoroughly cleaned. We also recommend roughing the surface by sanding or applying a coat of Primer M.
Wooden floors: make sure the blocks on the old floor are well-bonded to the substrate. Remove traces of varnish or wax from the surface of the floor with sandpaper down to bare wood and remove all dust with a vacuum cleaner. Then lay and bond the new floor dressing. 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. Mapei declines all responsibilities if all the screed manufacturer’s recommendations have not been followed; in case of doubt do not hesitate to contact you local Mapei’s Technical Services. Primer MF, Primer MF EC Plus: sand the primer while still fresh and the following day, when they are completely hardened, remove excess sand which has not bonded and start laying and bonding the dressing.
Spreading on the adhesive
Open the aluminium bag contained in the plastic drum and spread the contents on the substrate using a Mapei notched trowel for wood. The adhesive spread on the substrate must be covered with the wooden floor coating within approximately 110 minutes under normal conditions (+23°C, 50% R.H.). If adhesive from a previously opened pack is used, open the aluminium bag and remove the surface skin before application. The surface skin helps conserve the remaining quantity of the product.
Before laying, the parquet must be stored in a dry, condensation and vapour-free area protected against bad weather in the original packaging supplied by the manufacturer and must not be left standing directly on the floor. The level of humidity in the wood must be according to the values specified by the manufacturer on the Technical Data Sheet. When laying the parquet, press down firmly to make sure the back is well buttered. The special rheological properties of Ultrabond P980 makes it particularly easy to adjust the bonded elements after laying. Leave a 1cm wide joint around the edge of the floor and around columns or other bodies which pass through the floor. Make sure the adhesive does not spread into the joints in the slats to avoid staining the surface.
Sealing partially used containers
To store any remaining product after laying has been completed, remove as much air as possible from the aluminium bag to reduce the formation of surface skin and make sure it is well closed. Seal the bag with a plastic tie or similar system. Put the aluminium bag back into its original plastic tub.
