- Product Benefits
- High Gloss Sealer increases durability of concrete surfaces.
- High Gloss Sealer is ideal for interior surfaces where solvent-based material cannot be used.
- High Gloss Sealer will not yellow, haze or flake.
- High Gloss Sealer can be tinted with CSI Tint Concentrate WB* to enhance concrete that has been colored. (Tinted High Gloss Sealer is designed to enhance the look of concrete that has been colored, not to function as the primary coloring system.)
Applications & Uses
- Applications
- Application Method
- Pre-Application
- The surface should be clean and dry. If the surface is not completely dry, the product may turn white or hazy. 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 five pounds and below are acceptable. If measurements fall outside of this range, High Gloss Sealer should not be applied. This material is dependent on proper penetration. Any existing curing agents, coatings, sealers, oils, paints, dirt and/or efflorescence will inhibit penetration of High Gloss Sealer. Any materials that would prevent penetration must be removed before application. In the case of sealers, cures, and coatings, mechanical removal - such as shot-blasting, sand-blasting or terrazzogrinding - is advisable. Use a good commercial cleaner/degreaser to help remove grease and oil. Harsh chemicals should never be used to remove any of the materials cited here.
- Use the same equipment as with smooth surfaces but rinse with pressurewasher.
- Before applying product, test High Gloss Sealer in an inconspicuous area for desired results. If applying High Gloss Sealer over old sealer, paint or other coating, it is also important to test for adhesion in an inconspicuous area. If in doubt about application, contact ChemSystems, Inc.
- Application
- For smooth-troweled concrete, a microfiber applicator may be used. For rough surfaces or textured concrete, a 1/2 inch nap roller is recommended. Apply the sealer uniformly.
- Important: When applying High Gloss Sealer, do not allow the sealer to puddle. Apply the sealer as uniformly as possible, without leaving either spaces or puddles. It is better to apply two thin coats rather than one single, heavy coat. Allow each coat to dry before applying subsequent coats.
- For acceptable oil and water resistance, a minimum of two coats must be applied.
- For best results on interior surfaces with medium to high traffic, apply High Gloss Sealer and then apply a surface finish product or good commercial wax.
- Apply High Gloss Sealer when air and surface temperatures are above 50 °F and below 90 °F. Assure that temperature does not fall below 50 °F for 24 hours after application.
- Surface Protection and Maintenance
- Day-to-Day Cleaning – High Gloss Sealer, like all surface sealers, must be kept clean for maximum durability and protection. Frequent sweeping or vacuum-removal of loose soils will significantly increase the wear-life of High Gloss Sealer or any surface coating.
- Maintenance Cleaning – Surfaces sealed with High Gloss Sealer should be cleaned with a water-based detergent cleaner, rinsed and allowed to dry. On interior surfaces where routine maintenance is required, use a lowspeed buffing maintenance system.
- High Gloss Sealer may be removed using a good commercial paint stripper.
- For both indoor and outdoor surfaces, let dry before opening to traffic.

High Gloss Sealer exceeds coefficient of friction per ASTM D2047 standards for slip-resistance.
Technical Details & Test Data
- Coverage Rate and Drying Times
Coverage rates may vary depending on surface porosity, texture, age and condition of the concrete, the application method, and other local conditions. •
- Smooth Finish, Per Coat – Material usage, per coat, is approximately 300-400 square feet per gallon.
- Rough or Broom Finish, Per Coat – Material usage, per coat, is approximately 200-300 square feet per gallon.
Drying times below will vary depending on surface porosity, temperature, humidity and local conditions.
- Set to Touch – Surface can be lightly touched 30-45 minutes after application.
- Recoat – Surface can be recoated one to two hours after each application.
- Light Traffic – Light traffic can be allowed eight to twelve hours after final coat.
- Vehicle Traffic – Vehicle traffic can be allowed two to three days after final coat, depending on temperature. Hot tire traffic or extreme turning of vehicles on the surface prior to proper drying time may leave permanent black marks or may remove sealer.
Safety & Health
- Limitations and Precautions
- High Gloss Sealer is not a curing compound. Do not apply product to freshly placed concrete. Allow at least 14 days for concrete to cure. For optimum results, allow concrete to cure for 28 days or longer.
- If applying High Gloss Sealer to existing extremely hard-troweled concrete, a light acid etch and neutralizing may be needed.
- High Gloss Sealer will protect concrete from dusting and soiling if applied properly, evenly, and with sufficient coverage as outlined in the application directions.
- Failure to remove dirt and debris from the surface or failure to properly clean the surface will result in premature wear and will limit your ability to protect the concrete.
- Do not apply High Gloss Sealer if the surface or ambient temperature is below 50 °F or above 90 °F, or if the temperature is expected to fall below freezing (32 °F) within the 24-hour curing cycle.
- Adhesive-backed tape (such as duct tape) left on High Gloss Sealer over an extended period of time will create a chemical “weld” between the tape and the sealed substrate. If this happens, the sealer may be subject to delamination. Delamination can also occur when plastic or synthetic rubber mats are placed on the surface and left undisturbed over extended periods and when rubber tires on the sealed surface have been exposed to heat.
