- Use
KEMPERDUR® TC Traffic Coating is used as a heavy-duty coating for balconies, terraces, parking decks, walkways, and other traffic locations. The system may be used in conjunction with a fully reinforced KEMPEROL® cold liquid-applied, two component polyurethane resin waterproofing membrane or directly to a primed concrete substrates where a full reinforced waterproofing membrane is not required. Applications over unoccupied spaces may utilize the KEMPEROL® waterproofing flashing membrane at perimeter and penetration only.
- Limitations
Concrete surfaces to receive the TC Traffic Coating system must be properly designed and constructed in order to assure effective coating performance. Determine whether the concrete contains sufficient expansion/cold-joints prior to the application of the coating.
Note: If the concrete substrate does not contain adequate cold joints, additional cold joints must be created in the TC Traffic Coating system, at minimum every 20’. Contact manufacturer for the cold joint application process.
Minor yellowing will occur under UV exposure without approved KEMPERDUR® sealants.
KEMPERDUR® TC Traffic Coating may be applied only when the ambient temperature is 41ºF to 90ºF, and the substrate temperature is a minimum of 5 degrees above the dew point.
KEMPERDUR® TC Traffic Coating is intended for application on horizontal surfaces and inclines of up to 3%. A TX Thixotropic additive must be used on inclines from 3-20%.
- Yield
40 ft² / 12.5 kg work pack
Note: All yields are approximate and may vary depending upon smoothness of substrate.
- Surface Preparation
All surfaces must be free from gross irregularities, loose, unsound or foreign material such as dirt, ice, water, grease, oil, release agents, lacquers, or any other condition that would be detrimental to adhesion of the primer and surfacing.
Remove or grind down all fasteners, anchors, studs, or other protrusions to achieve a smooth surface.
- Priming
When applying directly to the concrete substrate, the surface must be prepared in accordance with the current application procedures. All cracks, holes, spalls, and other surface defects must be be sealed / repaired prior to the coating application. Review the current Substrate Repair and Patching Materials as well as the EP / EP5 primer slurry patching procedures. Once the substrate is prepared, primed, and all cracks are stripped in with KEMPEROL® 2K-PUR reinforced membrane, the KEMPERDU® TC application may commence.
- Mixing of Coating
When applying directly to KEMPEROL® two component polyurethane resin, TC traffic coating must be applied within a 48 hour window. If that is not possible due to the logistics of the projects the surface of the membrane must be first be lightly abraded. KEMPEROL® two component polyurethane resin must not be primed prior to the application of the coating.
Step 1 : Pre-mix Component A (white formulation) with a spiral KEMPEROL® agitator for 1 minute, until the liquid is a uniform color and all solids that may have settled to the bottom of the can have been mixed. When working on a sloped area, from 3-20%, such as a ramps, add approximatly 90g of KEMPERTEC® TX Thixotropic additive to Component A before adding Component B.
Step 2 : Add Component B (dark brown formulation) and mix with a spiral agitator for 1 minute, until the liquid is a uniform dark beige color without light or dark streaks.
Step 3 : Gradually add Component C (white mineral filler) to the liquid while mixing continuously for an additional 1 minute until a smooth, lump free mixture is produced.
Note: Do not break down units into smaller quantities - mix the entire work pack.
- Coating Application
Step 1: Empty the pail of KEMPERDUR® TC Traffic Coating mixture onto the primed concrete surface or over fully cured membrane and spread with a ¼” square-notched steel trowel at the rate of approximately 40 ft² /12.5 kg unit. If applying over cured membrane follow membrane re-coating guidelines.
- Step 1a: When applying the KEMPERDUR® TC traffic coating on an incline with the TX Thixotropic additive ensure that the coating does not run down the slope. If the coating shows signs of sag add additional additive.
- Step 1b: Due to the TX Thixotropic addive the coating will no longer self level. Use the flat side of the trowel to level out the coating on sloped surfaces.
Step 2: Immediately de-aerate the coating in a cross direction with a porcupine (spiked) roller in order to release the air bubbles that may develop within the coating.
Step 3 : Allow the KEMPERDUR® TC Traffic Coating mix to self-level and reach an initial set for 10 - 20 minutes, depending on ambient and surface temperatures, until material will retain a peak after being touched by a gloved finger.
Step 4 : Broadcast selected aggregate to excess into TC Traffic Coating until a uniform dry aggregate layer has been achieved. Aggregate will initially sink into surfacing, requiring the application of additional aggregate. Sufficient aggregate application is achieved when there are no wet spots remaining. Aggregate application rate is typically 100 lbs./100 ft.
- Surfacing Sand (0) #18 (0.5 - 1.2 mm) for applications utilizing a colored finish top coat
- Surfacing Sand (1) #14 (0.8 - 1.5 mm) for a more coarse surfaces, such as ramps
- Ceramaquartz (30 mesh) (0.3 - 0.6 mm) (S-Grade blend) for esthetic color quartz finished surfacing
Step 5 : Allow the aggregate-filled KEMPERDUR® TC Traffic Coating to cure for approximately 4 hours. Times may vary depending on temperatures. Remove excess aggregate by brooming and vacuuming.
Step 6 : Roller-apply appropriate sealer or finish evenly onto the surface. Ensure to lap each preceding path to erase squeeze out from the edge of roller.
