SURFACE PREPARATION
|
|
| To maintain warranty, subfloor must be properly primed. Use DEPENDABLE PRIMER SL on all surfaces. All supporting surfaces shall be structurally sound, solid, free of movement and well bonded. They shall be free of dust, oil, grease, tar or other contaminants that may act as a bond breaker. Do not apply over single stripwood floors or over wood subfloors prone to excessive swelling (not exterior glue or “underlayment” grade).
Subsurface must be essentially watertight, as DEEPFLOW is flowable. Make sure any holes, cracks, etc. that would permit material through to a lower level are patched or filled with DEPENDABLE WHITE SKIMCOAT® or POLYSKIM® prior to priming.

PRIMING
|
|
Use a long handled roller, soft bristle broom, or paint brush to apply DEPENDABLE PRIMER SL at full strength. Do not dilute. Do not cover until very tacky or dry (about 1 hour).
|
|
MIXING
|
|
Premix product, water add only:
Mix one bag of DEEPFLOW into 1.50 gallons (5.69 liters) cool clean water. DEEPFLOW can be mixed in large quantity in mortar mixers or special pumps or in smaller quantities in a 40 gallon container. Dependable Mixer Pump is available, request information through Dependable Technical Services. Use only a very clean mixing container that does not contaminate DEEPFLOW with other material. Pour in proper amount of water and then add powder while mixing. Do not over-water. If a problem is encountered with the mixing device getting a lump and powder free mix, try starting with 2/3 of proper water, adding powder until just wetted then adding remainder of water and thoroughly mixing. Mix with a mixing paddle (D-1 or A-1) or similar tool or device designed to avoid air entrapment at a slow mix (about 150-450 RPM). Mix for at least 2 minutes, but no longer than 3 minutes to a homogenous lump-free mixture. Do not shake.

APPLICATION
|
|
| Pump or pour contents onto floor. Allow DEEPFLOW to build in one area until it reaches at least desired depth and maintains that depth even as material flows away. Begin at a corner of room or at a deep part of fill. Plan the pour before starting. Either work back and forth along a line of the room or from the center of the fill outwards in all directions to keep pouring against the freshest material possible. Work the transition points between pours and material over or under desired depth with a screed (D-2 spreader) set to the desired depth or lightweight float or straightedge. Material should remain workable and can be walked in for 15 to 20 minutes at normal temperatures. Spiked sandals (A-4) can be helpful. Any imperfection can be smoothed by surface troweling or drawing a straightedge (D-3 smoother) over the surface. Direct sunlight, heat and wind can cause rapid drying of the product which may reduce working time. To avoid rapid drying, provide protection against these elements.
DEEPFLOW may be covered as soon as sufficiently dry to accept the desired adhesive or covering. (Usually at least 2 days for each inch of thickness) If an impervious covering is being installed such as laminate or vinyl sheet flooring be sure that DEEPFLOW is thoroughly dry (timing varies depending on thickness, temperature and humidity).For the application of ceramic tile with a portland cement based mortar bed, seal the Deepflow with the Primer SL prior to installation. Allow Primer SL to thoroughly dry. Let material continue to dry before covering until evaporative moisture lessens. Moisture level may be checked by a surface moisture meter, a plastic film taped to the floor, or a plastic bucket left on the floor and the area carefully observed for residual surface moisture upon removal. May be covered is as little as 3 hours in thin application as soon as sufficiently dry to accept the desired adhesive or covering. If an impervious layer (vinyl, laminate) is being installed over the floor such as laminate or vinyl sheet flooring, be sure that GSL is thoroughly dry (usually 8-24 hours depending on thickness, temperature and humidity).
For the application of ceramic tile with a portland cement based mortar bed, seal the Deepflow with the Primer SL prior to installation. Allow Primer SL to thoroughly dry.

LIMITATIONS
|
|
| Do not use where surface or ambient temperature falls to or below 45 F°, 72 hours before or after installation.
After installation, temporary wood planking should be used to protect the floor from heavy wheel loads.
Must be covered by floor covering systems.
Do not use where excessive hydrostatic pressure or extreme moisture conditions exist.
Do not use over presswood, particle board, masonite, chipboard, single stripwood floors, luaun or similar dimensionally unstable materials susceptible to moving or swelling.
