Moisture Barrier

To protect your cork flooring investment from sub–floor moisture, you may want to consider a moisture barrier underlayment. If you're installing cork flooring over a concrete floor at or below ground level, it is always recommend you use some type of moisture underlayment. When installing cork flooring over a plywood sub–floor, the moisture barrier is suggested but not always required. Check with your professional flooring retailer and installer and confirm manufacturer recommendations for your specific cork flooring.

Adhesive (Glue)

Glue–down cork tiles will require special flooring adhesive available at your local flooring retailer.


Cork flooring will expand and contract in reaction to humidity and temperature changes, so it is important to leave extra space along the wall edges during installation. Trims and moldings are used to hide the extra spacing, as well as to create transitions between rooms.

  • T–moldings: Used in areas where floors of similar height meet, such as doorways. T–moldings are also used as expansion joints on large floating floor installations.
  • Reducer moldings: Used to transition from rooms with cork floors to rooms with lower floor coverings like concrete or vinyl.
  • Stair Nose: Cork can be used on stairs with a stair nose molding to round the leading edge of the stains and to protect the edge of the cork on the stair tread.
  • Quarter Round/ Base Shoe: Covers the expansion gap between the floor and the wall. Smaller expansion gaps can be disguised with wall base trim.
  • End cap/ Threshold: Normally used to provide a transition between cork flooring and exterior doorways such as patio doors. The end cap molding hides the cut edges of the cork floor and provides a straight clean edge.
