Features & Benefits

Ultrabond Eco V4 Evolution is a synthetic polymer-based adhesive in water dispersion, formulated in a ready to use light beige paste.

Due to its particular formulation and extended open time, it can be used as wet-bed adhesive for all kind of floorings on absorbent substrates, as well as transitional pressure-sensitive adhesive for bonding dimensionally stable floor coverings on impervious, non absorbent substrates.

• Particularly suitable for the installation of modular LVT
• For use on floors and walls in interior applications
• Suitable as wet-bed adhesive on:
  • Level, absorbent surfaces
  • Underfloor heating systems
• Can be used for:
  • Static and dynamic loads, including intense loads, in residental, commercial and industrial environments (e.g. in hospitals, shopping centers, airports, etc.)
  • Stresses from chair castors according to EN 12529
• Also suitable as transitional pressure-sensitive adhesive for bonding dimensionally stable floor coverings on impervious, non-absorbent substrates

• Use Ultrabond Eco V4 Evolution for bonding:
  • Homogeneous and heterogeneous PVC floor coverings, sheets and tiles
  • CV and multilayer PVC floor coverings
  • Rubber floorings (sheets and tiles, including multilayer floor coverings with acoustic or foam underlay)
• Suitable also as a universal adhesive for:
  
  • LVT (Luxury Vinyl Tiles)
  • Modular LVT
  • SPC, rigid-core and hybrid, LVT
  • Semi-flexible vinyl floor tiles (VCT)
  • Textile floor coverings with all common backings (latex-primed, PVC and polyurethane foam, natural jute and Action-Bac , etc.)
  • Needle-punch woven flooring also in latex
  • Flocked textile flooring
  • Linoleum with natural jute backing
  • Polyurethane, polyolefin and synthetic back linoleum flooring
  • Polyolefin-based and chlorine-free floor coverings (PO)
  • PUR floor coverings (PU)
  • PVC and rubber wall coverings
  • Indoor sport floorings

Recommendations

• Install in recommended temperatures, normally between +15°C and +35°C
• Do not install on substrates not protected from rising damp
• Use reactive adhesives (such as Adesilex G19, Adesilex G20 or Ultrabond Eco MS1) in the event of extreme temperatures due to solar radiation, intense mechanical stress by lift truck, forklift, etc. or moisture from above (in particular when the floor coverings are not welded or sealed)

Application

Preparation of the substrate:

• Substrates must be dry, 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; alternatively, in case of dimensionally stable floorings, use the product as a “pressure sensitive”, that is, apply the floor covering after the water has evaporated off and the film of adhesive is touch-dry but still tacky (after approx. 30-40 minutes)
• It is essential to make sure there is no rising damp present
• Un-bonded screeds laid over light-weight concrete or over insulation and screeds laid directly onto earth must be separated by a vapour barrier to prevent rising damp

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:

• Ultrabond Eco V4 Evolution 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 alternatively (ensure the wetting of the backing material is warranted)

Installing the flooring:

• Follow the manufacturer’s instructions
• Wet bonding (on absorbent substrates):
  • Leave a waiting time (10-20 minutes) 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 andwith good transfer to the backing of the covering
  • Place the floor covering into the still wet adhesive bed: 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 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
• Pressure sensitive bonding (only for dimensionally stable floor coverings on impervious substrates):
  • Only in case of thin or solid color floor coverings, pass a nap roller onto the ridges of the still wet adhesive in order to impress them, before allowing the adhesive to air-dry until it has taken on a uniformly yellowish transparent colour (approx. 30-40 minutes) - it is recommended to test with a finger to make sure it is touch-dry but still tacky
  • When installing impervious sheet floor coverings, the Double Drop technique can be used to reduce the time taken waiting for the adhesive to dry
  • Lay the floor covering on the wet adhesive, press all over to achieve transfer, then pull it back exposing the adhesive
  • Leave until the adhesive has dried to a firm tack before replacing the flooring accurately in position

Cleaning:

• While still wet, Ultrabond Eco V4 Evolution can be cleaned from floor coverings, tools and clothings with water
• When dry, clean with alcohol or a suitable solvent

Consumption:

• Consumption varies with uniformity of substrate, the back of the flooring and type of trowel used:
  
  • MAPEI trowel no. 1: approx. 250-300 g/m²
  • MAPEI trowel no. 2: approx. 350-400 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
