All surfaces must be structurally sound, clean and free of dust, grease,
oil, water, curing compounds, and any foreign materials that may inhibit
bond. Follow applicable TCA, ANSI, NTCA specifications.
Screw or nail loose floorboards. If the subfloor is
less than 1” thick, cover it with 1/2” thick exterior grade plywood. Leave
a minimum of a 1/4” gap between all sheets or where they abut surrounding
walls or fixtures. Fasten plywood with 5d or 6d cement coated screw shank
nails.
Concrete must be fully cured (at least 28 days after
pouring), free of excessive moisture, alkalinity, and hydrostatic pressure.
It is the responsibility of the user to determine the condition of all
concrete substrates prior to installation.

Apply a thin coat of Hydroment Ultra-Premium Mastic using the flat
side of the trowel to achieve a good mechanical bond to the substrate,
then spread the mastic with the recommended size notched trowel for the
type of tile being installed.
Apply no more than can be tiled in 45 minutes. Do not set tile after
a skin has formed on the mastic. If skinning occurs, re-apply fresh mastic
before continuing. Press or twist individual tile or sheets of tile into
the combed mastic. Check a tile or sheets of tile occasionally to ensure
at least 95% coverage on the back of the tile. Always beat the tile in
with a rubber face beating block to ensure maximum contact and bond. Proper
installation requires a finished mastic bed thickness of 1/32” after beat-in.
Avoid mastic squeeze up between tiles. Do not walk on floors set with Hydroment
Ultra Premium Mastic for at least 12 hours unless walking boards or plywood
sheets are used.
Wait a minimum of 24 hours before using Hydroment grouts. Reference
data sheet or packaging for instructions.
Remove uncured adhesive with soap and warm water. Remove cured adhesive
with mineral spirits.
Close container between application cycles and after use. Store at
temperatures between 35°F and 100°F. Protect from freezing. Shelf
life is one year from manufacturing.
