Nail Down
Typically used with 3/4" solid wood flooring, however, on some flooring nailer models there are adapters
plates available for the base of the manual 
flooring nailer or the pneumatic nailing gun,
for thinner solid and engineered flooring sizes as well. For 3/4" thick flooring 2"
nailing cleats are normally used to attach the flooring to the subfloor. Although there are 3
different size cleat nails that can be used for different installation applications and
wood thicknesses. Solid wood flooring should only be installed on wooden subfloors on or above grade.
Staple Down
A modified pneumatic flooring nailer that is used to drive 1-1/2" - 2" Staples versus cleats to attach tongue
and groove engineered or solid wood flooring to the subfloor. A pneumatic nailing gun is used to drive the
staple into the wood flooring and subfloor. Wood flooring 5/8" or thinner would most likely require a smaller
pull trigger pneumatic nailing gun and smaller sized staples. Read the manufacturers installation manual
to assure you have the right staple gun and right size staples for your particular flooring.
Glue Down
Can be another optional installation method for installing tongue and groove engineered wood flooring and
some 5/16" thick solid wood flooring other than nailing or stapling the flooring down. The recommended
adhesive is spread on the subfloor with the proper sized trowel to adhere to the wood flooring to the subfloor.
Engineered wood floors and parquets can be glued down. There are many types of adhesives on the market and
they are all expensive. Not using the manufacturers recommended adhesive and trowel size may void any
warranties you may have with the flooring, although if the floor should fail due to adhesive failure then the
adhesive company would normally cover the cost of the flooring.
Floating
With the floating installation method, the engineered wood floor is not mechanically fastened to any part of
the subfloor a bead of recommended wood glue is applied in the groove of each plank to glue the planks together.
There is a thin underlayment pad that is placed between the wood flooring and the subfloor to provide a cushion.
This underlayment also retards any moisture transfer from below and can reduce noise when walked on and makes
the floor softer underfoot. Nowadays most engineered floors and engineered Longstrip floors can be floated.
Installing a floating floor is a fast, easy method of installation. Please consult the engineered manufacturer's
installation instructions to see if your flooring can be floated.
Click Loc
Many manufacturers are using newly developed ways to install their engineered flooring by milling the board's
tongue and grooving design into a click lock floating floor system where the boards simply fold and lock together
with no messy glue or clamping. This proven method has clearly made the process of installing wood and laminate
flooring a lot faster and easier than any other type of installation method. More and more wood flooring
manufacturers are offering this style of floating floors every day. All laminate flooring has the click loc design.
