Elongation

16 mils w.f.t

between -1 °C and 32 °C (30 °F and 90 °F)

Substrate temperature must be at least 3 °C (5.5 °F) above measured dew point temperature.

between -1 °C and 32 °C (30 °F and 90 °F)

Moisture content of concrete substrate must not exceed 4 % by mass (p.b.w. – part by weight) as measured with a Tramex® CM/E concrete moisture meter on a mechanically-prepared surface (mechanical preparation to ICRI / CSP 3 minimum). Do not apply to concrete substrate with moisture levels exceeding 4 % mass (p.b.w. – part by weight) as measured with the above mentioned equipment. If moisture content of concrete substrate exceeds 4 % by mass (p.b.w. – part by weight) as measured with Tramex® CM/E concrete moisture meter, contact your local Sika Representative.

• 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).
• Protect or remove food items prior to application to avoid any possible contamination.
• 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.
• Concrete should have a minimum compressive strength of 21 MPa (3,000 psi) and be cured for a minimum of 28 days.
• Do not apply Sikalastic® Vehicular Traffic 2900 to concrete slabs on grade, unvented metal pan decks, or split slab applications with a waterproofing membrane between slabs. Contact Sika Technical Services.
• Be sure to allow for movement in the deck by the proper design and use of expansion and control joints.
• Select the proper type and amount of aggregate to achieve the desired slip resistance.
• 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.
• CAD & PDF deck coating details are available for download from our website, Sika Customer Support can direct you to the site.
• 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.

Concrete
Concrete must be fully cured (28 days), structurally sound, clean, and dry (ASTM D 4263). All concrete surfaces (new and old) must be shot blasted to remove previous coatings, laitance, and all miscellaneous surface contamination and to provide a profile for proper adhesion. Abrasive shot blasting must occur after a concrete repair has taken place. Acid-etching is not permitted. The proper profile should be a minimum of ICRI CSP3 (as described in ICRI document 310.2R - 2013.) For balconies and other pedestrian areas with limited space or access to shot-blasting, alternative mechanical methods can be used to achieve the recommended surface profile.

• Repair voids and delaminated areas with SikaEmaco®-6000. When time permits, SikaEmaco®-1060 or SikaEmaco®-1060 EX may be used for repair purposes. Wait 6-8 hours before applying the Sikalastic® Vehicular Traffic 2900 system.
• Prime with Sikalastic® P 280 FS before applying SikaEmaco®-6000. Measure 3 quarts of resin and 1 quart of Sikalastic®-908 FS into the pail and add the proper amount of powder hardener. See the mixing chart below. Mix with a drill mixer for 30 seconds or until the powder hardener is completely dissolved.
• Apply primer at approximately 100 ft2 (9.3 m2 ) per mixed gallon.
• Measure, add, and mix the SikaEmaco®-6000 Resin, Powder Component, and necessary aggregate (if required) in the proportions recommended below.
• Use mixture to repair any damaged concrete, or to slope any areas as needed.
• Once cured, the material must be re-primed before the topping system is applied.
• Proceed with the application as usual.
• All units must be within the specified pot life.

Mixing

Measure 3 volume of Sikalastic® P 280 FS and 1 volume of Sikalastic®-908 FS into the pail, blend, and add the proper amount of powder hardener. See the mixing chart below. Mix with a drill mixer for 30 seconds or until the powder hardener is completely dissolved.

Sikalastic® 2900 System is a multiple-component system that utilizes a methyl-methacrylate (MMA) resin. It is critical that the instructions listed in the Safety Data Sheet and on the product label for every component of the system be read, understood, and followed. MMA resins are flammable liquids in their uncured state. Smoking, open flames, or sparks should not be permitted during the handling of the product. Explosion-safe ventilation must be used during the application to minimize vapor collection in the installation area and to improve overall air quality for the crew. All foodstuffs must be removed during installation of the system.

Heavy-duty Traffic System

1. Apply the properly mixed Sikalastic® P 280 FS/Sikalastic®-908 FS resin to the properly repaired concrete or properly prepared aged coating at approximately 100 ft² (9.3 m²) per mixed gallon or about 16 mils. Allow the primer to cure tack-free to an even, satin-like gloss and re-prime any dry spots.
2. Apply the properly mixed Sikalastic® M 290 FS at 32 ft² (3 m²) per gallon or 50 mils, using a notched tool (or trowel). Material may not be completely tack-free upon cure. Do NOT backroll the Sikalastic® M 290 FS.
3. Apply the properly mixed Sikalastic® TC 297 FS at 80 ft² (7.4 m²) per gallon, rolling on at a 20 mil thickness.
4. Immediately broadcast 16–30 mesh, rounded silica sand into the wet coating to refusal at the rate of 20–30 lbs per 100 ft² (1.0–1.5 kg/m²). Immediately after the aggregate is broadcast and while the coating is still wet, blow any excess aggregate via a portable blower forward into the wet coating.
5. Apply the properly mixed Sikalastic® TC 299 FS at 80 ft² (7.4 m²) per gallon, rolling on at a 20 mil thickness using a squeegee.
