Features & Benefits  

• Ultrabond Eco 380 is a “Pressure sensitive” adhesive with strong and fast initial tack, very long open time, for vinyl floor and wall coverings
• Recommended for:
  • Static and dynamic loads, including intense loads, in residential, commercial and industrial environments (such as hospitals, shopping centres, airports, etc.)
  • Wheelchairs in compliance with EN 12529
• Ultrabond Eco 380 is used for bonding:
  • Heterogeneous and homogeneous PVC tiles and rolls
  • Cushion floor and multi-layered PVC
  • Semi-flexible vinyl tiles
  • Carpet with latex mesh, PVC foam and polyurethane backing   
• Product Properties:
  • Very easy to apply
  • Strong, tough initial tack
  • Extended open time
  • Excellent permanent tack
  • Tough, elastic film with “leg-effect”
  • Excellent adhesion to all types of substrate
  • Suitable for all areas used by wheeled vehicles in compliance with regulation DIN EN 12529
  • Solvent-free
  • Non-inflammable
  • Harmless for floor installers and end users

Recommendations

• Bond flooring at the specified temperature, usually from +15°C to +35°C
• Do not bond flooring on substrates without protection against rising damp
• If there are particularly high temperatures due to direct sunlight, high mechanical loads from fork-lifts, etc. or high levels of damp (especially if the floor covering has not been welded or sealed) use a reactive adhesive
• For vinyl floor coverings with poor dimensional stability, use a specific adhesive with the capacity to withstand movements caused by temperature variations

Application

Preparation of the Substrate:

• Substrates must be flat, dry, absorbent, strong, free of dust, loose material, cracks, paint, wax, oil, rust and traces of gypsum or any other material that could affect adhesion
• Apply a layer of smoothing compound at least 3mm thick on non-absorbent substrates
• Alternatively, use the product as a “pressure-sensitive” adhesive, that is, apply the floor covering after the water has evaporated off and the film of adhesive is transparent but still tacky (after approx. 60-70 minutes)
• In all cases, always comply with local norms and standards where the product is used
• 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 floated 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 floorcovering
• It is very important to check that there is no rising damp
• Floating screeds installed on lightened sub-layers or insulating material and screeds laid directly on the ground must be isolated by laying a vapour barrier

Acclimatisation:

• Prior to installation, make sure the floor covering and substrate have been acclimatised at the specified temperature and level of R.H

Spreading the adhesive:

• Supplied ready to use and does not require any preparation
• Mix the adhesive well in its tub before use
• Spread the amount of adhesive required on the substrate using a suitable notched trowel

Installation of the flooring:

Follow the manufacturer’s instructions

• Installation may be carried out after waiting the specified time (10-20 minutes), depending on how much adhesive has been applied, the surrounding conditions, the absorbency of the substrate and the type of floor covering
• The adhesive must be applied within its specified open time of 60-70 minutes
• The floorcovering should be rolled with a 68 kg roller immediately after it has been installed, starting from the centre and working towards the edges to ensure the adhesive is transferred to the back of the floorcovering, and any air bubbles removed
• If necessary repeat the rolling operation after a few minutes
• If the floor covering is very thin, make sure the rolling phase also eliminates any streaks in the adhesive which could show through the surface
• The floor may be stepped on with care after 3-4 hours (according to the surrounding temperature and absorption of the substrate)
• Floors are ready for use after approximately 48 hours
• When laying onto non-porous surfaces or low porosity surfaces, a suitable levelling / smoothing compound from the Mapei range should be overlaid at a minimum thickness of 3mm to provide an absorption layer
• Application can then proceed as for porous surfaces

Note: waiting and open times may vary, depending on the surrounding temperature, relative humidity and absorbency
of the substrate. Waiting and open times are shorter at high temperatures and low levels of humidity and longer at low
temperatures, high levels of humidity or if applied on non-absorbent substrates.

Pressure sensitive bonding:

(Only for CV and dimensionally stable PVC coverings on impervious substrates)

• Allow the adhesive to air-dry until it has taken on a uniformly yellowish to transparent colour (approx. 60-70 minutes); it is recommended to test with a finger to make sure it is touch-dry but still tacky

Cleaning:

• Easy to remove from floors, floor coverings, tools, hands and clothing with water while still wet
• Once dry, it must be removed with alcohol or a specialist solvent cleaner

Storage and Safety Instructions

Storage:

• Remains stable for at least 12 months under normal conditions in its original, sealed packaging
• Do not expose to freezing weather for long periods

Safety Instructions: 

• Not considered as dangerous according to the current regulation regarding the classification of mixtures
• We recommend to wear protective gloves and goggles and to take the usual precautions for handling chemicals
