Application Tips

  • Requires atmospheric moisture to cure
  • Must not be applied below 5°C
  • Do not apply in greater thicknesses than that allowed by specified trowel (side movement and/or lifting may occur)
  • Selleys Technical Services should be consulted if any doubt exists in respect to floor contamination, or any concerns in relation to moisture
  • Should a self-levelling compound be required, consult manufacturer in relation to drying times and appropriate priming to adhere the compound to the substrate
  • Where a hydrostatic pressure may be present, suitable drainage must be installed and VBS moisture vapour barrier employed

Technical Details and Performance

For strip flooring, trowel onto substrates with the recommended notched trowel (5mm wide by 6mm high V notches at 25mm centres). For parquetry blocks a finer & closer notched trowel is required to avoid excess adhesive; e.g. a 2.4mm wide x 2.4mm high v-notches at 4.8 centre. (Consult “Product Application Information” sheet available from Selleys).

170,000 CPS, @ 25°C, 50% R.H.

Shelf Life

12 months in unopened container. Opened cans may skin on the surface and this may be cut off and remaining product used.

Bond Strength

7.0Mpa lap shear

Liquid Nails Direct Stick is easy to trowel. When spreading, the consistency of the adhesive forms ridges that do not slump. This results in better contact for bonding on uneven substrates and vertical surfaces. IMPORTANT: It is essential for best results and coverage that the appropriate trowel be used.
