DIRECTIONS:
Refer to flooring manufacturer’s
specific recommendations. Condition the area to be installed,
adhesive, underlayment and flooring at 65°F (18°C)
or above for 48 hours before, during and 48 hours after
installation. Maximum temperature for use is 90°F
(32°C). Floor must be sound, smooth, dry, clean
and free of excessive moisture or alkali. Remove dirt,
wax, polish, paint and all other foreign matter that
would interfere with a good bond such as curing agents
and sealers.
- Slightly
dampen concrete substrates with clean water and apply
underlayment while damp. Do not leave standing water.
- For
a superior bond, prime wood with HENRY 336 Floor Primer
and Latex Liquid Additive.
- Mix
powder into water slowly and carefully to the proper
consistency.
- Can
be applied in one layer featheredge to 1/2" thick
or two layers to a maximum thickness of 1".
- Mix
approximately 25 lbs of powder to 2-1/2 quarts of
water.
- Mixing
containers must be clean as unused material will contaminate
newly mixed underlayment.
- Do
not add additional water after the proper consistency
has been reached. If underlayment starts to set before
using, discard and do not attempt to remix.
- Scratch
or trowel to the substrate to be certain it wets properly
and thus assures good adhesion.
- Start
finishing immediately using a steel trowel.
- Do
not over-trowel or re-trowel.
- Clean
tools with water frequently and dip trowel in water
often to make finishing easier.
- All
finishing must be done within 20 to 30 minutes. Allow
to dry 1 to 3 hours before installing floor covering.
- Most
adhesives will exhibit shorter working times when
used over HENRY 445.
