DMX 1-STEP 2.0 ™ ADVANCED VAPOR BARRIER
INSTALLATION CHECKLIST
Remove old floor, and underlayment that are unsound or deteriorated
Any previous rigid floor can be left in place if it is sound and firmly adhered to the
substrate
Do not attempt to remove asbestos tiles yourself, have a remediation professional do this who
is licensed
Clean and sweep the concrete floor (or the existing flooring if it is sound)
Inspect for cracks in the concrete
For cracks larger than 1/16”, fill with a concrete repair product (As per Installation Video)
Check the level of the concrete floor with a straight edge ruler, Flooring Manufacturers suggest
a maximum variance of 3mm over 3m, or 1/8” over 10’
For height variations in your floor of 3mm or less, use DMX Easy Shims, a package of 10 shims
is included with every roll. If the height variation in your floor is greater than 3mm, then we
recommend using a floor patch (leveling) compound to level the floor.
DMX Easy Shims are nested in the dimples on the top of DMX 1-Step 2.0 ™ (blue side). Therefore,
DMX Easy Shims will be sandwiched between the finished floor and DMX 1-Step 2.0™.
The height of 1 shim is 1mm, you can nest up to 3 shims (3mm) to correct the level of your
floor. The shim is laid between DMX 1-Step 2.0 ™ Advanced Vapor Barrier and the finished floor
Lay DMX 1-Step 2.0 ™ Advanced Vapor Barrier with the dimples facing down (Blue Side Up)
Tape the seams with DMX Joining Tape
Lay down your laminate, engineered hardwood or vinyl plank flooring (5 mm minimum for
application directly on top of DMX 1-Step 2.0 ™Advanced Vapor Barrier)
Follow the Flooring Manufacturer’s installation instructions for proper fit of the floor
Leave a 1/4” expansion gap between the wall and flooring along the perimeter of
the wall
Leave the baseboards up off finished floor a minimum of 1/16” to 1/8” for air
