Installation Instructions - Hardwood Flooring - Floating


Your home must be kept between 35-50% RH at 21 C for at least one week prior to installation.  The wood must read between 6% - 8% and be a maximum difference from the subfloor of 4% (for a wooden subfloor) or albs or less per 1000 sqft for a concrete subfloor.  The goal is to have the moisture level in your home to be stable with the hardwood being installed, to lessen the seasonal movement that occurs. Moisture testing for concrete subfloors is done by use of calcium chloride tests.  Three calcium chloride tests are required for the first 1000 sqft, and one more per each additional 1000 sqft.  Please follow the instructions on the test.

General Information

  • Inspect the subfloor for flatness (should be within 1/8" over a 6' area).
  • Inspect the subfloor for squeaks and flatness (fix any problems before you start - the prep makes all the difference.
  • Use a High-Quality Membrane 
  • Inspect the floor during installation for milling and finish defects.
  • Floor should be installed from several cartons at once to ensure evenness of look.

Required Tools

  • Pencil
  • Chalk Line
  • 6' Level
  • Miter Saw
  • Table Saw
  • Broom
  • Jam Saw
  • Eye Protection
  • Dust Mask
  • Gloves
  • Membrane
  • Hygrometer & Calcium Chloride Tests
  • Tape Measure
  • Transitions
  • Wood Glue (for transitions)


  • Cover the entire subfloor with the membrane.  If the membrane doesn't have a self-adhesive strip, use tuck tape to cover seams to provide a water-resistant base.
  • Determine the starting wall, usually the longest or outside foundation wall.  Start on the left corner leaving a 1/2" expansion space, although if you undercut the drywall that already gives you approximately that, with the groove facing you.
  • Moving right, put the next bird in place.  Insert the end tongue into the end groove of the first board.  Continue in this way until it is time to cut the last board to finish the first row.
  • The board chosen to finish the first row should be long enough to start the second row with the trimmed board, as to minimize waste.  Leave a 1/2" gap at the end to allow the board to expand in all directions.
  • The boards must be spaced 5-6" apart, to allow for a random look.  
  • Inerst the tongue at the side of the board into the groove of the first row at a 45 degree angle.  Line up the far left side, set the board down and apply slight pressure to lock in place.  Install subsequent rows in the same way. 

Finishing Up

  • The last row will most likely have to be cut down to properly fit.  
  • Don't forget the expansion space!
  • Install baseboards, and do your touchup painting (As required).
  • Install EZ Glides on all furniture, to protect your beautiful new floor.
