NOTES ON INSTALLATION
- In cold weather, store the container at room temperature for at least 24 hours before using.
- Do not allow uncured Sikaflex® HY 100 to come into contact with alcohol-based materials or solvents.
- Sikaflex® HY 100 should not be applied adjacent to other uncured sealants and certain petroleum-based products.
- Sikaflex® HY 100 can adhere to other residual sealants in restoration applications. For best results, always clean the joint as advised in the Surface Preparation section of this data guide. A product field adhesion test for Sikaflex® HY 100 within the specific application is always recommended to confirm the adhesion and suitability of the application.
- Sikaflex® HY 100 should not be used for continuous immersion in water. Contact Technical Services for recommendations.
- Do not use Sika® Primer-179 on nonporous surfaces such as aluminum, steel, vinyl, or PVDF based paints. Use Sika® Primer-173 on PVDF coated metals when testing dictates.
- Lower temperatures and humidity will extend curing times.
- Sikaflex® HY 100 can be painted over after a thin film or skin forms on the surface.
- In green concrete applications, sealing joints in concrete prior to 72 hours after concrete placement will impact the ability of the sealant
- to gain adhesion. Use Sika® Primer-173 or Sika® Primer-179 should be used as a primer in all green concrete applications. It is always recommended to conduct a mock up when applying HY 100 to green concrete.
- Pursuant to accepted industry standards and practices, using rigid paints and/or coatings over flexible sealants can result in a loss of adhesion of the applied paint and/or coating, due to the potential movement of the sealant. However, should painting and/or coating be desired it is required that the applicator of the paint and/or coating conduct on-site testing to determine compatibility and adhesion.
- 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.
SUBSTRATE PREPARATION
Substrates must be structurally sound, fully cured, dry, and clean. Substrates should be free of the following: dirt, moisture, loose particles, oil, grease, asphalt, tar, paint, wax, rust, waterproofing or curing and parting compounds, membrane materials, and sealant residue.
Concrete, Stone, And Other Masonry
Clean by grinding, sandblasting, or wire brushing to expose a sound surface free of contamination and laitance.
Metal
- Remove scale, rust, and loose coatings from metal to expose a bright surface.
- Test all coatings on metal that cannot be removed to verify the adhesion of sealant or to determine an appropriate primer
Wood
- New and weathered wood must be clean, dry, and sound.
- Scrape away loose paint to bare wood.
- Test all coatings on wood that cannot be removed to verify adhesion of sealant or to determine an appropriate primer.
- For freshly treated wood; allow six months for weathering.
Joint Preparation
- Design the number of joints and the joint width for a maximum of ±50% movement.
- In optimum conditions, the depth of the sealant should be 1/2 the width of the joint. The sealant joint depth (measured at the center) should always fall between the maximum depth of ½" and the minimum depth ¼". Refer to Table 1.
- In deep joints, control the sealant depth by installing Closed-Cell Backer-Rod or Soft Backer-Rod. Where the joint depth does not permit the use of backer-rod, use a bond breaker (polyethylene strip) to prevent three-sided adhesion.
- To maintain the recommended sealant depth, install backer-rod by compressing and rolling it into the joint channel without stretching it lengthwise. Closed-Cell Backer-Rod should be about 1⁄8" larger in diameter than the width of the joint to allow for compression. Soft Backer-Rod should be approximately 25% larger in diameter than the joint width. Because the sealant does not adhere to the backer-rod, no separate bond breaker is required. Do not prime or puncture the backer-rod.
MIXING
Sikaflex® HY 100
Sikaflex® HY 100 comes ready to use. Apply using a professional-grade caulking gun. Do not open cartridges or sausages until preparatory work has been completed.
Sikaflex® HY 100 Tint Base
Sikaflex® HY 100 Tint Base needs to be pigmented with Sikaflex®-900 pigment to be used. Do not open pails until preparatory work has been completed.
To pigment material
- Transfer the entire contents of one Sikaflex®-900 pigment into the Sikaflex® HY 100 Tint Base.
- Add one can of Sikaflex®-900 pigment to one 1.5 gallon pail of Sikaflex® HY 100 Tint Base.
- Use a spatula or knife to remove all the pigment from the container.
- Mix with a slow-speed drill and slotted paddle for 3-4 minutes until the color is uniform.
- During the process, scrape the sides and bottom of the mixing container several times.
APPLICATION
Sikaflex® HY 100 & Sikaflex® HY 100 Tint Base
- NOTE: Sikaflex® HY 100 is not a structural sealant.
- Fill joints from the deepest point to the surface by holding an appropriately sized nozzle against the back of the joint.
- Dry tooling is recommended. Proper tooling results in the correct bead shape, neat joints, and optimal adhesion.
- Best practices dictate that all caulking and sealing be done when temperatures are above 40 °F (4 °C) to avoid application to moisture‑laden surfaces. Moisture on substrates will adversely affect adhesion. Application may proceed as low as 20 °F (-6 °C) if there is certainty that substrates are completely dry, free of frost, and clean as described under Surface Preparation.
- Sikaflex® HY 100 Tint Base needs to be apply using a professional-grade bulk gun. Place the lid securely on the pail when not in use to maximize pot life.
CLEANING OF TOOLS
- Immediately after use, clean equipment with SikaSwell®-990 or xylene. Use proper precautions when handling solvents.
- Remove cured sealant by cutting with a sharp-edged tool.
- Remove thin films by abrading.
