Mapei Ultrabond Eco VS90 Plus

Product Overview

Mapei Ultrabond Eco VS90 Plus is a hard set, highly shear resistant, wet-bed dispersion adhesive, specific for PVC and rubber floorings and wall coverings on absorbent substrates. Available 15kg tubs.

Mapei Ultrabond Eco VS90 Plus is particularly suitable for fixing decoupling membranes. Also, be used to stick down our Floating Floor Panels and our Overlay Panels. The substrate will need primer.

Mapei Ultrabond Eco VS90 Plus is a universal, high-temperature solvent-free, non-staining acrylic adhesive in water dispersion, formulated in an easily trowellable paste. It has very low emissions of volatile organic compounds (EMICODE EC 1). Mapei Ultrabond Eco VS90 Plus is non-flammable and contains no toxic substances. It can therefore be stored without special precautions and presents no health hazard during use.

Mapei Ultrabond Eco VS90 Plus is suitable for use on floors and walls in interior applications, on the level and absorbent surfaces, and in underfloor heating systems. It can be used for static and dynamic loads, including intense load, in residential, commercial, and industrial sectors (e.g. in hospitals, shopping centres, airports, etc.) and stresses from chair castors according to EN 12529.

Recommendations

• Install Mapei Ultrabond Eco VS90 Plus in recommended temperatures, normally between +15°C and +35°C.
• Do not install Mapei Ultrabond Eco VS90 Plus on substrates not protected from rising damp.
• Use Adesilex G19 or Adesilex G20 in the event of extreme temperatures due to solar radiation, intense mechanical stress by a lift truck, forklift, etc., or frequent rinsing (in particular when the floor coverings are not welded or sealed).
• In the case of multilayer cork planks with PVC backing, use Ultrabond Eco 310.

Application Procedure

• Preparation of the substrate
  Substrates must be dry, absorbent, level, sound, mechanically strong, free of dust, loose particles, cracks, paints, wax, oil, rust, traces of gypsum or other products that can interfere with bonding. On non-absorbent substrates, apply a smoothing compound to a minimum thickness of 2 mm.
  The moisture content must comply with the local regulations. It is essential to make sure there is no rising damp present. Unbonded screeds laid over lightweight concrete or over insulation and screeds laid directly onto earth must be separated by a vapour barrier.
• Acclimatisation
  Before starting the installation, make sure that the floor or wall covering and the substrate are acclimatised to the recommended temperatures and R.H.
• Spreading the adhesive
  Mapei Ultrabond Eco VS90 Plus is ready to use and does not need any preparation. Before using, stir the adhesive in the bucket. Apply a suitable quantity of adhesive to the substrate with a suitable notched trowel. When installing thin wall coverings, a long nap roller may be used as an alternative (ensure the wetting of the backing material).
• Installing the flooring
  Follow the manufacturer’s instructions. Leave enough waiting time depending on the application quantity, climatic conditions, substrate absorbency, and type of cover. Only apply as much adhesive as can be covered within the open time and with good transfer to the backing of the covering. Lay the floor covering whilst still wet: the adhesive ridges have to be impressed. Take care to avoid air pockets and carefully rub the floor covering down to ensure good adhesive transfer to the backing. Avoid excessive stress at the seams. After some minutes of installing the floor covering, it is always necessary to carefully roll it down again or to firmly rub it down.

Note: waiting and open time may vary depending on temperature, relative humidity, and absorbency of the substrate. They will be shorter at higher temperatures and lower humidity, but longer at lower temperatures, higher humidity, and with low absorbent substrates.
