Color:

Gray

NOTE: Weather and temperatures, amount of water used as well as care used in the application are all

factors over which we have no control. We assume no warranty for finished work, expressed or implied.

Our liability is limited to the replacement of defective materials.

Preparation:

Concrete:

1. All materials should be stored between 40° F (4° C) and 80° F (27° C)

24 hours prior to installation.

2. Concrete must be fully cured (28 days minimum), free of efflorescence, and

not subject to hydrostatic pressure or moisture condensation.

3. All surfaces must be clean, stable, solid, and structurally sound. Remove all

unsound concrete, grease, oil, dirt, paint, sealers, curing compounds, waxes,

old adhesive residue, gypsum based underlayments, old flooring, and any other

foreign materials that will inhibit adhesion. Mechanical removal is recommended,

chemicals often serve to drive them deeper into the concrete substrate.

4. Maximum bond over a concrete substrate can be achieved by mechanically

profiling the surface either by grinding, shot blasting, sand blasting or

scarifying to achieve an ICRI CSP3 to CSP5 standard. Structurally sound

concrete that is porous, and has not been troweled smooth and flat may not

require mechanical profiling. Typical applications that fall into this category

include precast concrete floor panels, or concrete in new construction that is

left unfinished in anticipation of receiving self-leveling underlayment.

5. Repair deep areas, holes, and non-moving cracks with Sakrete Top N Bond

or an appropriate concrete repair product prior to the application of the self-

leveling and allow curing as recommended for the product.

6. All surfaces require priming using a self-leveling bonding primer. Allow primer

to dry to the touch.

7. Isolate and install a bond breaker, using ¼” (6 mm) foam tape or caulking,

where vertical surfaces meet new toppings and at all perimeters and sharp

corners such as column bases, pedestals, supports, etc.

Wood Substrates:

Residential and light commercial foot traffic, interior applications only

1. Follow Tile Council of North America (TCNA) F185 installation method for

cementitious self-leveling underlayments over wood.

2. All wood subfloors must be structurally sound and securely fastened. When

using as an underlayment the maximum deflection allowed is L/360 for ceramic

tile, or L/720 for stone (including live, dead, impact and concentrated loads).

3. The wood must be either ¾ in. (19 mm) tongue and groove, APA rated exterior

grade/exposure 1 plywood or OSB underlayment grade equivalent.

4. The surface must be clean, free from any contaminants that may act as bond

breakers such as dirt, paint, wall compound, varnish, grease, oils, or wax.

All loose boards must be refastened and sound.

5. Allow a 1/8 in. (3 mm) gap between sheets. Fill gaps and all nail holes or

areas where flow could leak with caulk.

Fast Setting Self-Leveling Resurfacer TM 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.
