WOOD BONDING NEW is a moisture curing one-part wood flooring adhesive.
Solventless, isocyanate free, virtually no schrinkage, fast curing it shows high cohesion,
permanent elasticity, very good resistance to moisture and good adhesion to substrates.
• One-part product, ready to use without mixing
• No shrinkage
• Solventless and isocyanate free
• Permanently elastic from –40°C to +90°C
• Fast neutral curing
• Odourless
• Good resistance to ageing and moisture
• Sound and vibration dampening
• Very good adhesion to wood, concrete, ceramic and metals
• High final bond strength
• Permanently elastic
• Suitable for underfloor heating

Typical uses:

• For bonding many kinds of parquet and wooden floors onto suitable indoor substrates.
• In combination with Primer LMBV is suitable for bonding teak, iroko and douglas ship decks.

Method of us:

Surface preparation: Wood Bonding New adhesive should be applied to an even, dry, clean and smooth subfloor, which is also free
from irregularities and cracks.
Substrates that are not solid enough should be removed or, where possible, consolidated with Primer LM100.
The moisture level of the subfloor should be within the recommended levels for the installation of wooden flooring: generally not
exceeding 75% RH or, depending on the test method used, max 2% for sand cement substrates and max. 0,5% for anhydrite.
For substrates with underfloor heating the values are respectively max. 1,8% and 0,3%.
The wood to be installed must be stored in a dry place protected from bad weather and not subject to vapour condensation.
It must be insulated from the ground. Before installing check that the moisture content of the wood is within the recommended
7-11% values range.
For existing ceramic tile, marble, etc. flooring: they must be clean with any grease removed and the surface dry before the adhesive
is applied.
Application of adhesive: Wood Bonding New can be applied in a temperature range +5°C-+35°C (optimum 15°C / +25°C) with max
65% RH. The same conditions of temperature and RH are valid for an appropriate acclimatization of parquet for some days before the
laying. The adhesive is ready to use, should be applied by means of a notched spatula to the substrate.
Within 40-60 minutes from the application and in any case before skin formation, lay down the wooden laths.
During installation pressure should be applied to ensure the adhesive wets the back of the wood: a minimum of 80% contact coverage
is required to ensure a perfect adhesion. Loading the parquet with weights will improve the final bond strength.
After 24 hr. the floor can be finished.
Yeld: depending on the substrate, can vary from 1,6 to 2 kg/m2.

Adhesion and surface preparation: the surfaces must be dry, clean and degreased.
Metal surfaces should be free from oxidation and treated with anticorrosive protection.
Onto treated metals, the use of a suitable Primer may be required, so previous testing is always recommended.
Onto dry and deoxidated metal surfaces use Primer WP.
Wood free from dust, dry and degreased should be treated with Primer LM/BV.
GRP free from dust should be cleaned with acetone.
For special operating conditions, such as the presence of moisture, or on porous surfaces, the adhesion can improved by applying
a special primer. More detailed information on surface preparation are contained in the selection chart “Primer for MS sealants”.
Application of adhesive: apply Wood Bonding New on the surface to be coated, then spread with a notched trowel in order to obtain
a uniform thickness, sufficient to ensure the contact between the adherends after the installation of the deck.
Lay the wood strips or boards within 20’ from the drafting of the adhesive, in any case before the skin appears, to be verified
especially inhot and humid summer conditions.

Yeld: depending on the substrate, can vary from 2,5 to 3 kg/m2.
