APPLICATION INFORMATION

 

Consumption

Full Surface Bonding:

• 600−800 g/m2 with notched trowel B3 (TKB Germany) e.g. for lam parquet,
  mosaic parquet and industrial parquet.
• 700−900 g/m2 with notched trowel B6 (TKB Germany) or SC+ MB
  (US Standard) e.g. for engineered wood strips and planks, lam and mosaic parquet.
• 800−1000 g/m2 with notched trowel B11 (TKB Germany) or P5 (US Standard) e.g. solid wood, engineered long-strips and panels, industrial parquet, other
  residential wood floors and paving, and chipboard.
• For bonding long or wide boards and on uneven substrates, it may be
  necessary to use a larger notched trowel to ensure that a sufficient amount of
  SikaBond® T-55 J is applied to provide a uniform adhesive bed to prevent hollow
  sections without full surface bond.
• For substrates primed with Sika® Primer MB, the consumption of
  SikaBond® T-55 J may be reduced.

 

Sag / Flow

• SikaBond® T-55 J spreads very easily whilst maintaining stable trowel
  ridges.

 

Ambient Air Temperature

• >15ºC – <35ºC

 

Relative Air Humidity

• 40% to 70%

 

Substrate Temperature

• During laying and until SikaBond® T-55 J has fully cured, the substrate
  and ambient temperatures shall be between +15 °C and +35 °C, and between +20 °C and
  +35 °C with underfloor heating.

 

Substrate Moisture Content

Permissible substrate moisture content without underfloor heating:
1. 2.5% CM for cement screeds.
2. 0.5% CM for anhydrite screeds.
3. 3–12% CM for magnetite flooring (depending on the organic content).

Permissible substrate moisture content for use with underfloor heating:

1. 1.8% CM for cement screeds.
2. 0.3% CM for anhydrite screeds.
3. 3–12% CM for magnetite flooring (depending on the organic content).

Note: For all moisture contents, the quality of the substrates and surfaces, always
follow the guidelines of the wood flooring manufacturer.

 

Curing Rate

• 3.0 mm/24 hours approx. (23 °C / 50% r.h.)

 

Skin Time / Laying Time

• 60 minutes approx. (23 °C / 50% r.h.)

 

IMPORTANT CONSIDERATIONS

• SikaBond® T-55 J is only suitable for use by professional wood floor
  applicators.
• For good workability, the adhesive temperature shall be ≥ +15 °C.
• For proper curing of the adhesive, sufficient ambient humidity /
  moisture is necessary.
• A preliminary adhesion test is necessary before any application on
  glazed tiles.
• Before wood floors may be installed in non-insulated areas, such as
  basements or other areas without a damp proof membrane, Sikafloor® EpoCem must be
  applied and sealed with Sika® Primer MB to control the moisture. For detailed
  instructions, contact our Technical Service Department.
• For use with chemically pre-treated types of wood floors (e.g. those
  produced or treated with ammonia, wood stain, timber preservative) and woods with a
  relatively high oil content, SikaBond® T-55 J is only to be used with the written
  agreement of our Technical Service Department.
• Do not use on polyethylene (PE), polypropylene (PP),
  polytetrafluoroethylene (PTFE / Teflon), and other similar plasticized synthetic
  materials.
• Some other floor priming materials can negatively influence the
  adhesion of SikaBond® T-55 J (pre-trials recommended).
• SikaBond® T-55 J is designed as a wood floor bonding adhesive. When
  laying parquet type wood floors without tongued and grooved joints, e.g. mosaic
  parquet floors, avoid the wood floor adhesive extruding into the joints between the
  wood pieces.
• Avoid contact between any wood surface sealer coatings and adhesive.
  However, if direct contact with the adhesive is unavoidable, then the compatibility
  must be checked and confirmed before use of any coatings. For further information
  and advice, please contact our Technical Service Department.
• Do not expose uncured SikaBond® T-55 J to alcohol containing products
  as they may interfere with the curing reaction. For further information and advice, please contact our Technical Service Department.

 

CLEANING OF EQUIPMENT

• Clean all tools and application equipment immediately after use with
  Sika® Remover-208 and/or Sika® Colma Cleaner.
• Once cured, residual material can only be removed mechanically.
