• If a vapor drive is present or suspected, please consult with your local Sika representative prior to system application.
• Not for use in areas exposed to strong solvents (consult Sika Technical Service).
• Proper airflow is critical to curing MMA materials. The use of fans is mandatory where airflow is restricted.
• The minimum application temperature is -1 °C (30 °F) .
• Do not apply to concrete that is outgassing.
• Warm temperatures will shorten working time; plan work accordingly.
• New Concrete should have a minimum compressive strength of 21 MPa (3,000 psi) and be cured for a minimum of 28 days.
• Be sure to allow for movement in the deck by the proper design and use of expansion and control joints.
• Contact Technical Service when substrates are over 32 °C (90 °F)  or under -1 °C (30 °F)  or when applying to decks containing between slab membranes.
• The best method to ensure the proper wet film thickness is the use of a grid system. Divide the surface to be coated into grids and calculate the square footage of each. Refer to the coverage chart to determine the quantity of coating needed for each grid to arrive at the required mil thicknesses.
• Avoid application when inclement weather is present or imminent.
• Do not apply to damp, wet, or contaminated surfaces.
• Not suitable for use where chained or metal-studded tires will be used.
• Proper application is the responsibility of the user. Field visits by Sika personnel are for the purpose of making technical recommendations only and not for supervising or providing quality control on the jobsite.
• On steep ramps in excess of 15%, contact your local Sika representative. Do not use self-leveling grade products on slopes greater than 15%. Do not coat over expansion joints.

• Pre-Mix Sikalastic® M 290 FS until uniform (1-2 minutes). Measure the required volume of resin and add the proper amount of powder hardener Sikalastic®-918 FS. See mixing chart below.  Mix with drill mixer for 3 minutes.

Note: After mixing, apply immediately. You will have 7 – 15 minutes of working time, dependent on temperature.

Apply Sikalastic® M 290 FS at 50 mils w.f.t using a notched tool (or trowel). Material may not be completely tack free upon cure. Backroll the Sikalastic® M 290 FS only if necessary, to aid in leveling. If performed, backroll must be done immediately.

Please see the applicable Sikalastic®Deck Coating system data sheet for total system and aggregate surface preparation and application.
  

All components of the Sikalastic® Traffic 2900 system fully cure within one hour when properly installed. Extend the curing time in cool-weather conditions.

Clean tools with Sikafloor®-100 CLN Pronto, an MMA solvent. Other solvents such as xylene or acetone may also be used. Collect and dispose of all site waste.
