Please consult Sikafloor Technical Services.

Precondition material for at least 24 hours between 65° to 75°F  (18° to 24°C)

Minimum/Maximum 50˚/85˚F (10˚/30˚C)

 Maximum ambient humidity 85% (during application and curing)

Beware of condensation! 

The substrate must be at least 5˚F (3˚C) above the Dew Point to reduce the risk of condensation, which may lead to adhesion failure or “blushing” on the floor finish. Be aware that the substrate temperature may be lower than the ambient temperature.

Moisture content of concrete substrate must be ≤ 4% by mass    (pbw – part by weight) as measured with a Tramex® CME/CMExpert type concrete moisture meter on his product data sheet (preparation to CSP-3 to CSP-4 as per ICRI guidelines). Do not apply to concrete substrate with moisture levels > 4% mass (pbw – part by weight) as measured with Tramex® CME/CMExpert type concrete moisture meter. If moisture content of concrete substrate is > 4% by mass (pbw part by weight) as measured with Tramex® CME/CMExpert type concrete moisture meter, use Sikafloor 1610 or Sikafloor PurCem® 22NA or 24NA.

Before applying second coat of Sikafloor®-700 allow:

Approximately 80 - 130 ft2/ US gal (1.9 - 3.2 m2 / L) at 12 to 20 mils (0.3 – 0.5 mm) wet film thickness (w.f.t) or 240 - 390 ft2 /US gal (5.9 - 9.6 m2 / L) per 3 gallon unit over primed, relatively smooth, dense concrete surfaces.                                          

(The above figures do not allow for surface profile or waste)

Mix Ratio - 2 : 1 by volume.

For bulk packaging, when not mixing full units, each component must be pre-mixed separately to ensure product uniformity.                                                                                                                                                                                                                                

Field Pigmented:

1. Make sure all surface preparation is complete and installation equipment is ready before starting the mixing sequence.
2. Premix each Component separately, the appropriate Sikafloor Epoxy Color Additive-N is added to Component A at a rate of 1 quart per 3.0 mixed gallons (i.e. Components A+B).
3. Mix Component A and Sikafloor Epoxy Color Additive-N for 2 minutes or until a uniform color is achieved with a low speed drill (300 - 450 rpm) and Exomixer or Jiffy type paddle suited to the volume. Empty Component B (Hardener) in the correct mix ratio to Component A (Resin) and mix for additional 2 minutes. Be careful not to introduce any air bubbles while mixing.
4. Make sure the contents are completely mixed to avoid any weak or partially cured spots in the coating.
5. During the mixing operation, scrape down the sides and bottom of the container with a flat or straight edge trowel at least once to ensure complete mixing.

Note:

• For added film strength and chemical resistance, C type glass flake with epoxy silane treatment, 5 micron (µm) nominal size may be added at the rate of 15% by weight.  3 gallon mixed unit + 4.4 lbs (2.0 kg) of glass flake.    
• Do not mix more material than can be applied within the working time limits (i.e. Pot Life) at the actual field temperature.
• Mixing  must adhere to Material, Ambient and Substrate temperatures listed above or a decrease in product workability and slower cure rates will occur.

1. Pour a thin approximately 6 – 12 in. wide bead of Sikafloor 700 in the form of a ribbon on the surface and spread the material at a rate of approximately 130 ft2/ US gal (3.2 m2 / L) with a notched squeegee, flat squeegee, or trowel.
2. Apply as evenly as possible, working from left to right, and then back.
3. Back rolling is typically done with an 18 inch (454 mm) wide short nap, 3/8-inch (10 mm), solvent-resistant roller cover.
4. Back roll the Sikafloor 700 only to level the squeegee applied material.

Note:

• Over-rolling and late back rolling may cause bubbling and leave roller marks.
• Application must adhere to Material, Ambient and Substrate temperatures listed above or a decrease in product workability and slower cure rates will occur.
•   Ensure there is no vapor drive at the time of application. Refer to ASTM D4263, may be used for a visual indication of vapor drive.
• Will discolor over time when exposed to sunlight (UV) and under certain artificial lighting conditions. Use of clear UV resistant top coat may not prevent discoloration of underlying coatings.
• Do not apply Sikafloor to concrete substrate containing aggregates susceptible to ASR (Alkali Silica Reaction) due to risk of natural alkali redistribution below the Sikafloor product after application. If concrete substrate has or is suspected to have ASR (Alkali Silica Reaction) present, do not proceed. Consult with design professional prior to use.
• Any aggregate used with Sikafloor systems must be non-reactive and oven-dried.
• This product is not designed for negative side waterproofing.
• Use of unvented propane or natural gas heaters and certain heat sources may result in defects (e.g. blushing, whitening, debonding, etc.).
• Beware of air flow and changes in air flow. Introduction of dust, debris, and particles, etc.may result in surface imperfections and other defects.
