• In service temperature range: from -20°C to +80°C

Recommendations

• Before installing, make sure the rooms have suitable windows and fittings
• The humidity level in the screed must be compliant with that prescribed by the current standards for the installation of wood, and as indicated in the technical data sheet for the parquet
• If the substrate is not thoroughly dried, or if the residual humidity is higher than the level prescribed, we recommend the use of a suitable waterproofing primer
• If there is a risk of rising damp, a vapour barrier must be installed before laying the screed
• Do not use if the temperature is lower than +10°C or higher than +35°C
• Only carry out the installation if the walls and ceiling are thoroughly dried
• When transported over long distances, thermally insulated containers may be required

Application

Preparation of the substrate:

• The substrate must be checked carefully to assess its condition, and to prepare it for laying parquet
• Cementitious screeds: must be well cured, dry, flat and mechanically strong
• The surface must be free of dust, loose parts, oil, paint, etc
• The level of humidity in the screed must be measured using a carbide hygrometer
• To solve problems of residual humidity levels higher than those prescribed for laying, wait until the screed is dry, or apply a suitable waterproofing primer
• Cracks in the substrate must be repaired beforehand
• For installation on surfaces with traces of glue or old existing smoothing compounds, or for substrates in wood marine plywood, chipboard, ceramic or natural stone, use Eco Prim T Plus, Eco Prim VG
• Excessively rough or uneven surfaces should be levelled using a smoothing compound with high mechanical properties chosen according to the thickness to be installed
• Installation may be carried out once it has cured
• To install rapid-drying, controlled-shrinkage screeds, use a special Mapei hydraulic binder: Mapei Mapecem, which allows for installation after 24 hours, or Mapei Topcem for installation after 4 days
• Topcem Pronto or Mapecem Pronto pre-blended, ready-to-use mortar may be used as an alternative, and wood may be laid after 4 days and 24 hours, respectively
• In the presence of lightening layers or insulation, or in the case of screeds installed directly on the ground, a vapour barrier must be installed to avoid rising damp
• Old floors in ceramic, marble, etc. must be carefully cleaned and degreased before bonding
• The adhesive may only be applied once the surface is dry
• Wooden floors: make sure wooden floorboards are rigidly fixed to the substrate Remove old paint or wax with sandpaper down to the bare wood, and remove all dust - the adhesive may then be applied
• Anhydrite substrates: 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 with Eco Prim PU 1K, Eco Prim PU 1K Turbo, Primer MF and Primer MF EC Plus

Spreading the adhesive:

• Spread the adhesive on the substrate using a Mapei notched trowel for wood
• Wood has to be laid within approximately 35 minutes under normal temperature conditions (at +23°C and 50% R.H.)
• If left-over adhesive from previous applications is to be used, open the drum, remove the skin formed on the surface of the adhesive and proceed as above
• The layer of skin helps to preserve the left-over adhesive

Laying Parquet:

• The parquet to be laid must be stored in a well-protected, dry area in the original packaging supplied by the manufacturer, it must not be subjected to condensation and must not be stored directly on the ground
• The level of humidity in the wood must comply with the levels indicated by the Technical Data Sheet (see 'Data Sheets' section above)
• When laying, press down firmly to make sure the adhesive is well applied to all the wood
• The special rheologic properties of Ultrabond Eco S940 1K makes final adjustment easy
• Leave a joint approximately 1cm wide around the perimeter of the floor and around columns and other protruding points
• Make sure that adhesive does not seep through the joints to avoid dirtying the surface

Polishing:

• The floor may be polished after 3 days

Cleaning:

• May be removed using specialist cleaning solutions while still fresh
• Once hardened, it must be removed mechanically or with specialist solvent cleaner
