- Helix Epoxy Bonder has a mix ratio of 1:1, and can be diluted with water to reduce solids.
Applications & Uses
- Applications
- Application Method
- Compatible Substrates & Surfaces
- Pre-Application
- Surface preparation: When using Helix Epoxy Bonder, the surface must be structurally sound and clean—free of dirt, grime and other foreign substances like oils, silicones, all other waterproofing materials, form release agents, curing and parting compounds, and any sign of efflorescence. Surface also must be completely dry before application. If your surface is not clean or completely dry, the sealer may turn white or hazy, or the primer may fail to form a proper film and adhesion..
- Mixing ratios, surface moisture, application method, and temperature at time of application play a large role in the integrity and long-term durability of this primer. We strongly recommend sampling and testing this material prior to large-scale application.
- If aggressive moisture movement on interior concrete is suspected, exact moisture movement levels can be measured using a moisture test kit in accordance with ASTM D4263 standards, following the manufacturer’s instructions. Moisture measurements of six to eight pounds and below are acceptable. If measurements fall outside of this range, Epoxy Bonder SD should not be applied.
- Hard troweled burnished concrete must be chemically or mechanically prepared to promote proper adhesion. Extremely dense or burnished surfaces should be slightly abraded to better accept Helix Epoxy Bonder.
- ChemSystems, Inc. utilizes the International Concrete Repair Institute (ICRI) Concrete Surface Profile (CSP) standards for specifying finishedsurface roughness prior to applying Helix Epoxy Bonder. For proper adhesion, the concrete must be a minimum #1 according to the ICRI CSP chart. Contact the ICRI at www.ICRI. org or ChemSystems, Inc. for more information on these surface profiles.
- . Helix PolySeal WB should only be applied to substrates above 50 °F and below 90 °F.
- Application
Helix Epoxy Bonder should be applied only after concrete has fully cured, approximately 28 days
Warning! Do not apply Helix Epoxy Bonder to fresh concrete
- Helix Epoxy Bonder is not recommended for application over surfaces previously painted or sealed with other sealers.
- Before applying product, test Helix Epoxy Bonder in an inconspicuous area for desired results. For application questions, contact ChemSystems, Inc.
- The following mixing instructions for Epoxy Bonder must be strictly adhered to. Epoxy Bonder has a mix ratio of 1 part A to 1 part B. Add Part B (cure) t of Part A (resin) in an open container. Mix well. Helix Epoxy Bonder will initially turn slightly opaque when mixed, but will dry clear. Before Helix Epoxy Bonder dries, clean equipment with water.
- Helix Epoxy Bonder is best applied with a high-quality, 1⁄4-inch short nap roller.
- Helix Epoxy Bonder , should not be applied at film thicknesses greater than 10 mils wet per coat. Roll out the primer so it soaks into the surface.
- If applying to extremely porous surface (like bead-blasted concrete), test a small amount of the primer in an inconspicuous area to determine number of coats required for adequate coverage. Porous surfaces may require two coats.
- Cement-based top coats and overlays can be applied when Helix Epoxy Bonder is tacky.
- If broadcasting sand, use coarse grit and broadcast to rejection within 1 hour of primer application. Let the primer cure for 24 hours, then remove excess loose sand.

Safety & Health
- Limitations and Precautions
- Do not apply Helix Epoxy Bonder if the surface or ambient temperature is below 45 °F, above 95 °F, or if the temperature is expected to fall below freezing (32 °F) within the 24-hour curing cycle
- Failure to remove dirt and debris from the surface or failure to properly clean the surface before application will result in poor adhesion.
