NOTES ON INSTALLATION
Observe Working Time Limitation
- Catalyze no more material than can be applied within the work time period.
- Available work time, temperature and complexity of the application area will determine how much material should be catalyzed at one time.
- Keep material cool and shaded from direct sunlight in warm weather. During hot weather, work time can be extended by keeping material cool before and after mixing or by immersing pot in ice water.
Maintenance
- Periodically inspect the applied material and repair localized areas as needed. Consult a Sika representative for additional information.
- Visit us on the web for the most current product information and news: usa.sika.com.
SUBSTRATE PREPARATION
The concrete surface should be prepared to a minimum concrete surface profile (CSP) 3 defined by the ICRI surface-profile chips. Localized out-of-plane variations, including form lines, should not exceed 1/32 in. (1 mm). Surface must be clean and sound. It may be dry or damp, but free of standing water and frost. Remove dust, laitance, grease, curing compounds, impregnations, waxes, foreign particles, disintegrated materials, and other bond inhibiting materials from the surface
MIXING
- The mix ratio is 3:1 (Part A to Part B) by volume or 100:30 (Part A to Part B) by weight. Mix only the amount of material that can be used within the working time of the material. Approximate working times for a 1 gal (3.8 L) unit are: 95 min at 50° F (10° C) 40 min at 77° F (25° C) 15 min at 90° F (32° C)
- Part A (resin) must be pre-mixed using a low-speed drill (600 rpm) and mixing paddle (e.g., a Jiffy Mixer). Keep the paddle below the surface of the material to avoid entrapping air. Pre-mix for a minimum of 3 minutes.
- Carefully measure (ratio) each component and then add Part B (hardener) to Part A (resin).
- Mix Parts A and B using a low-speed drill (600 rpm) and mixing paddle (e.g., a Jiffy mixer). Carefully scrape the sides and bottom of the container while mixing. Keep the paddle below the surface of the material to avoid entrapping air. Proper mixing will take at least 3 – 5 minutes. Well-mixed material will be free of streaks or lumps.
- If a thicker consistency is desired, silica flour (S-11 Powder) may be mixed into the material using a low-speed drill and mixing paddle. Add as much silica flour as is needed to achieve the desired consistency.
APPLICATION
- Apply the Sikadur® F 2000 to the primed substrate using a spring-steel trowel.
- For bonded, external reinforcement: Apply the neat mixed Sikadur® F 2000 onto the concrete with a trowel or spatula to a nominal thickness of 1/16” (1.5 mm). Apply the mixed Sikadur® F 2000 onto the CarboDur® laminate with a “roof-shaped” spatula to a nominal thickness of 1/16” (1.5 mm). Within the open time of the epoxy, depending on the temperature, place the CarboDur® laminate onto the concrete surface. Using a hard rubber roller, press the laminate into the epoxy resin until the adhesive is forced out on both sides. Remove excess adhesive. Glue line should not exceed 1/8 inch (3 mm). The external reinforcement must not be disturbed for a minimum of 24 hours. The epoxy will reach its design strength after 7 days.
- For interior vertical and overhead patching: Work the material into the prepared substrate, filling the cavity. Strike off level. Lifts should not exceed 1 inch (25 mm).
CLEANING OF TOOLS
Use xylene or methyl ethyl ketone. Observe fire and health precautions with solvents.
