6. Prime clean surface with a self-leveling bonding primer that is designed for
wood substrates. Allow primer to dry to the touch.
7. Securely fasten every 4-6 in. (10-15 cm) either galvanized metal lath or
plastic lath designed for this purpose to the wood surface after priming, and
prior to applying self-leveling cement. Overlap lath edges by ¼ in. (6 mm) and
secure using a minimum 3/4 in. (19.0 mm) staple with no gaps, keeping lath
flat. Be sure to offset lath joints. To keep the job moving, it is helpful to prime
first, then stand on the lath while fastening securely.
8. Install expansion joints where self-leveling cement meets restraining surfaces
such as perimeter walls and sharp corners such as column bases, pedestals,
supports, etc. using ¼ in. (6 mm) foam tape or caulking.
9. When using Sakrete Fast-Setting Self-Leveling Resurfacer over lath, install no
less than 1/4 in. (6 mm) thickness of self-leveling above the surface of the lath.
Note: Before installing Sakrete Fast Setting Self-Leveling Resurfacer the installer is responsible for
ensuring that the wood subfloor is structurally sound, clean and capable of support the weight.

Mixing:
1. In a clean 5 gal. container, add 4.75 quarts (4.5L) of clean, cool, potable water.
Next add the 50 lb. (22.7 kg) bag of powder, while mixing at full speed using a
square mortar paddle mixing blade attached to a heavy-duty ½ in. drill (400-
600 rpm). Measure water carefully, be accurate, DO NOT ADD EXTRA WATER
or segregation and soft surfaces can occur.
2. Mix completely for a minimum of 2-3 minutes until lump free, adding no
additional water. Avoid overwatering, over mixing, or moving the mixer up and
down during mixing as this will entrap air , lower the strength, and may cause
cracking and/or pin-holing. The formation of a white film on the surface is an
indication of over watering.
3. For larger jobs, to keep the job moving, it is recommended that multiple
mixing containers be used simultaneously. This will allow one mixing
container to be poured while the other is being mixed.
4. After use clean all mixing equipment thoroughly to avoid hardened product in
subsequent batches.
5. Fast Setting Self-Leveling Resurfacer may be extended up to 50% with clean
pea gravel (3/8 in.) for areas deeper than 1 inch (25 mm). For best results,
apply a final ¼ in. to 1 in. (6-25 mm) topping layer without extension. A self-
leveling primer must be used when layering.
Placement:
1. Apply only to surfaces that are frost free and between 50° – 90° F
(10° – 32° C) for 24 hours prior and 48 hours after application.
2. Close all interior windows, doors, and HVAC vents to minimize air flow. Protect
exterior application areas from excessive drying due to temperatures, air
movement, direct sunlight and rainfall.
3. Divide the areas to permit continuous placement without cold joints.
4. Pour the blended Sakrete Fast Setting Self-Leveling Resurfacer directly from
the mixing container across the surface in a continuous, uniform manner to
achieve a flat, level surface. No troweling is required. The mixed compound
remains fluid for approximately 15-20 minutes.
5. To prevent ridges work a narrow dimension, best results are obtained pouring
across the shorter distance in the room in continuous strips about 1 foot
(31 cm) wide. Optimum results can be obtained by providing a continuous
wet flow throughout the placement, always pouring into a wet edge.
6. Troweling is not recommended, do not overwork material once it is on the floor.
7. Honor all existing expansion joints, control joints, and moving cracks through the
resurfacer application. Failure to do so could result in delamination or cracking.
8. Sakrete Fast Setting Self-Leveling Resurfacer has a working time of 25 to 30
minutes at 70° F (21° C).Temperature and humidity will affect flow, working
time, and set time.
9. If a higher build-up is needed over the first pour, allow 24 hours drying time
between pours and prime surface again with a self-leveling bonding primer.
10. Sakrete Fast Setting Self-Leveling Resurfacer will not correct or compensate
for a structurally defective substrate. Faults in the substrate will appear in
the resurfacer. The use of alkali resistant glass fabric or galvanized metal
reinforcing (Federal Specification QQL.101C) can be helpful in reducing
reflective cracking.
11. Typically surfaces will accept foot traffic in 6 hours, non-moisture sensitive tile
and stone in 24-48 hours, and resilient flooring after 3 days at temperatures
of 72° F (22° C).
12. Before laying floor tiles and other flooring materials test for MVER (moisture
vapor emission rate, reference ASTM F1869) and concrete substrate’s relative
humidity (RH, reference ASTM F2170). The requirements of the floor covering
and floor adhesive manufacturers must be followed with respect to, but not
limited to, levels of moisture.
Notes and Limitations:
1. Sakrete Fast Setting Self-Leveling Resurfacer may be used for outdoor
applications, the smooth surface may prove too slippery when wet. To
provide better traction, a light broom finish may be applied when material
has reached initial set. Most outdoor applications require the surface to slope
for drainage, however Fast Setting Self-Leveling Resurfacer flows easily to
provide a level surface and will not provide that slope.
2. Do not install over trowel or over work.
3. Metal or plastic lath design for this purpose is required when going over wood
subfloors (interior applications only), it is not needed over properly prepared
concrete surfaces.
4. When using lath, install no less than ¼ in. (6 mm) thickness of self-leveling
about the lath surface.
5. Do not install over dimensionally unstable substrates such as gypsum, gypsum
based patching compounds, particle board, luan, asbestos, or chip board.
6. Do not install over old tacky or pressure sensitive adhesive residue, paints,
sealers, curing compounds, old flooring, and other foreign materials.
7. Do not allow heavy or sharp metal objects to be dragged directly across the
fresh surface. Protect new surface from use until material is completely hard
and set.
8. Protect from excessive drying due to change in temperatures, air movement,
and direct sunlight.
9. The use of damp curing or the use of curing compounds is not recommended.
10. Allow 14 days curing time before turning on in-floor radiant heating systems,
bring heat up slowly during the first usage.
11. Rubber gloves and goggles are recommended safety equipment.
12. Store in tightly sealed original factory container.
13. Air, mix and substrate temperatures should be between 40° F (4° C) and
80° F (27° C) and no rain in the forecast within 24 hours of application.
14. Protect from freezing for 48 hours.
