Ultrabond Eco VS90 Plus is available in 15 kg

For use on floors and walls in interior applications

Suitable on:

• level and absorbent surfaces;
• 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 centers, airports, etc.);
• stresses from chair castors according to EN 12529.

Some application examples

Use Ultrabond Eco VS90 Plus for bonding:

• sheet and tile rubber ooring with smooth or textured surfaces;
• homogeneous and heterogeneous PVC  oor coverings, sheets and tiles;
• PVC and multilayer PVC oor coverings;
• LVT (Luxury Vinyl Tiles).

Also suitable as universal adhesive for bonding:

• Textile oor coverings with all common backings (latex-primed, PVC and polyurethane foam, natural jute and Action- Bac® backed carpets, );
• needle-punch woven  ooring also in latex;
• ocked ooring;
• semi- exible vinyl   oor tiles (VCT);
• linoleum with natural jute backing;
• polyurethane, polyole n and synthetic back linoleum ooring;
• polyole n-based and chlorine-free   oor coverings;
• PUR oor coverings;
• PVC and rubber wall

TECHNICAL CHARACTERISTICS

Ultrabond Eco VS90 Plus is an acrylic adhesive in water dispersion, formulated in a ready to use light beige paste. Characterised by a fast and strong initial grab and a rapid set, as well as a rigid and cohesive nal lm, it gives the oor coverings a very good dimensional stability.

Product properties:

• very easy to apply;
• little to no waiting time;
• excellent wetting even with dif cult covering;
• rapid set development;
• very good peel strength;
• highly shear resistant;
• very good dimensional stability;
• prevents open joints;
• exposure to castor wheels in accordance with DIN EN 12529;
• non- ammable;
• EMICODE EC1 Plus (very low emission);
• Blauer Engel - RAL DE-UZ 113;

RECOMMENDATIONS

• Install in recommended temperatures, normally between +15°C and +35°C.
• Do not install on substrates not protected from rising
• Use Adesilex G19 or Adesilex G20 in the event of extreme temperatures due to solar radiation, intense mechanical stress by lift truck, forklift, or moisture from above (in particular when the oor coverings are not welded or sealed).

APPLICATION PROCEDURE

Preparing 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 suitable MAPEI smoothing compound to a minimum thickness of 3 mm.

A British Standard approved test should give a reading of 75% RH or less, if this has not been achieved the use of a MAPEI Surface Membrane will suppress residual / static moisture in a power  oated concrete slab or sand/cement screed, provided that a base dpm has been incorporated. For gypsum and anhydrite substrates the maximum humidity level should be 0.5% as measured with a carbide hygrometer, and in all cases, no higher than the level recommended by the manufacturer of the oorcovering.

The regulations of each country must be strictly followed.

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 to prevent rising damp.

To repair cracks in the substrate, consolidate and waterproof screeds, form new fast-drying screeds and level uneven substrates, please refer to the relevant technical documentation or contact the MAPEI Technical Services Department

Acclimatization

Before starting the installation, make sure that the oor or wall covering and the substrate are acclimatised to the recommended temperatures and R.H.

Spreading the adhesive

Ultrabond Eco VS90 Plus is ready to use and does not need any preparation. Before using, stir the adhesive in the bucket. Apply the adhesive evenly 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  ooring

Follow the manufacturer’s instructions Leave a waiting time according to the application quantity, climatic conditions, substrate absorbency and type of covering. 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 oor covering whilst still wet: the adhesive ridges has to be impressed. Take care to avoid air pockets and carefully rub the oor covering down to ensure good adhesive transfer to the backing.

Avoid excessive stress at the seams. After some minutes installing the   oor covering, it is always necessary to carefully roll it down again or to rmly 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.

Cleaning

While still wet, Ultrabond Eco VS90 Plus can be cleaned from oor coverings, tools, hands and clothing with water. When dry, clean with alcohol or a suitable solvent.

CONSUMPTION

Consumption varies with uniformity of substrate, the back of the ooring and type of trowel used. MAPEI trowel no. 1: approx. 250-300 g/m²

MAPEI trowel no. 2: approx. 350-450 g/m² Roller: approx. 200 g/m²

Notch TKB A1/A2: approx. 200-300 g/m² Notch TKB B1: approx. 300-350 g/m² Notch TKB B2: approx. 350-450 g/m²
