Curing Time

Most of the components of the Sikalastic® Vehicular Traffic 2900 system fully cure within one hour when properly installed.  As an exception, Sikalastic® M 290 FS will cure within one to one and a half hours.

Concrete

1. 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 profile for proper adhesion. Abrasive shot blasting must occur after concrete repair has taken place.  Acid-etching is not permitted.  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 for shot-blasting, alternative mechanical methods can be used to achieve the recommended surface profile.

2.  Repair voids and delaminated areas with SikaEmaco 6000  refer to the product data sheet for specific instructions. When time permits, SikaEmaco 1060, 1060DR or 1060EX  may be used for repair purposes. Wait 24 hours before applying Sikalastic® Vehicular Traffic 2900.

• Prime with Sikalastic® P 281FS/ Sikalastic®-908 FS before applying SikaEmaco 6000. Measure 3 quarts of resin and 1 quart of Sikalastic® 908 FS into pail and add proper amount of powder hardener. See mixing chart below. Mix with 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 on the product data sheet. Use mixture to repair any damaged concrete, or to slope any areas as needed.
• Once cured, material must be re-primed before topping system is applied.
• Proceed with application as usual.
• All units must be within the specified pot life.

Surface Pre-Striping and Detailing

1.For non-moving joints and cracks less than 1 ⁄16" (1.6 mm) wide, Apply 6" pre-stripe with Sikalastic® P 281FS/ Sikalastic®-908 FS or Sikalastic® P 281 FS /Sikalastic®-908 FS using a short-nap roller, must be applied to fill and overlap the joint or crack 3" (76 mm) on each side. Just before application of Sikalastic® P 281FS/ Sikalastic®-908 FS or Sikalastic® P 281 FS /Sikalastic®-908 FS, remove all dust, dirt and contaminants. Allow Primer to dry tack-free. On the same day, apply a 4" pre-stripe with 25 mils of Sikalastic® M 290 FS. Sikalastic® M 290 FS must be applied to fill and overlap the joint or crack 2" (51 mm) on each side. Feather the edges.
NOTE: For non-moving joints and cracks, prime the crack before applying Sikalastic® M 290 FS at 25 mils using a notched trowel - for faster detailing.
2. Dynamic cracks and joints over 1 ⁄16" (1.6 mm) wide must be routed to a minimum of 1/4 by 1/4" (6 by 6 mm) and cleaned. Install bond breaker tape to prevent adhesion to bottom of joint. Prime joint faces only with Sika® Primer-173 and fill with Sikaflex® SL 2 or Sikaflex® NP 2. For joints deeper than¼" (6 mm), use appropriate backer rod. For cracks, sealant should be flush with the adjacent surface. For expansion joints, sealant should be slightly concave.
3. Sealed joints 1" (25 mm) wide or less can be coatedover with the Sikalastic®  Traffic system. NOTE: SYSTEM IS NOT TO BE APPLIED ON PLYWOOD. Expansion joints exceeding 1" (25 mm) wide, including the primary wide expansion-joint system, are not to be coated so they can perform independently of the deck coating system.
4.Form a sealant cant into the corner at the junction of all horizontal and vertical surfaces (wall sections, curbs, columns) by priming with Sika® Primer-173 and applying a 1" (25 mm) wide bead of Sikaflex® NP 2. Tool to form a 45° cant. Apply masking tape to the vertical surfaces 4–5" (102–127 mm) above the sealant cant to provide a clean termination of the vertical detail coat. After the sealant has cured, prime with Sikalastic® P 281FS/ Sikalastic® 908 FS or Sikalastic® P 281 FS /Sikalastic® 908 FS at 100 SF/gallon. Apply 25 wet mils (0.64 mm) of Sikalastic® M 290 FS over the cured cant up to the masking tape and 4" (102 mm) onto deck surface.
NOTE: For a non-moving can't bead, Sikafloor -100 PAS Pronto can be used for rapid cure, refer to the product data sheet for specific instructions.
5. Where the coating system will be terminated and no wall, joint, or other appropriate break exists, cut a 1/8 by 1/8" (3 by 3 mm) keyway into the concrete. Fill and coat keyway during application of Sikalastic® M 290 FS.

Please refer to the specific PDS for Mixing instructions and Sikalastic®-918 FS (Powder hardener) dosage.

Sikalastic®-918 FS is required to cure all components

The Sikalastic® Vehicular Traffic 2900 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 System

Heavy-Duty Traffic System
1. Apply the properly mixed Sikalastic® P 280 FS/Sikalastic®-908 FS or Sikalastic® P 281 FS/Sikalastic®-908 FS resin to the properly repaired concrete,for recoat application only use Sikalastic® P 281 FS/Sikalastic®-908 FS as a primer. Apply at approximately 100 ft² (9.3 m²) per mixed gallon or about 16 mils. Allow 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. Backroll the Sikalastic® M 290 FSS only if necessary, to aid in leveling. If performed, backroll must be done immediately.
3. Apply the properly mixed Sikalastic® TC 297 FS at 80 ft² (7.4 m²) per gallon, at 20 wet mils, using a squeegee and backroll method.
4. Immediately broadcast with the appropriate well-graded 16–30 mesh aggregate into the wet coating to refusal at the rate of 20–30 lbs per 100 ft² (1.0–1.5 kg/m²). Remove excess aggregate after cure. NOTE: Larger and angular aggregates can be used for a more aggressive texture. This will impact coverage rate of Sikalastic® TC 299 FS.
5. Apply the properly mixed Sikalastic® TC 299 FS at 80 ft² (7.4 m²) per gallon, Apply at 20 wet mils using squeegee and backroll method. All components of the Sikalastic® Vehicular Traffic 2900 system fully cure in approximately one hour when properly installed. Note: Aggregate selected must be well graded with minimum fines. Fines can inhibit wax formation and proper curing.
