H&C^® Clear 23 Sealer
H&C^® Clear 23 Sealer is a solvent-based sealer formulated with a silicone acrylic resin. It's an excellent topcoat to H&C^® Silicone Acrylic Concrete Sealer for added durability and a high gloss finish. It dries crystal clear and never discolors. It resists water, pool chemicals, most cleaning agents, ultraviolet rays and the heaviest traffic.

Where to Use
Interior and exterior, vertical and horizontal surfaces, like:

• Brick
• Stone
• Masonry
• Epoxy-Set Chatahoochee Stone

Supplies Checklist
You'll need a stiff broom, natural bristle brush, a soft-woven roller cover with a 3/8" - 1/2" nap, a roller frame and a paint tray.

You can also use an airless sprayer for ease and quickness. Make sure to back roll after airless spraying to work the product smoothly and evenly into the surface. This will decrease the possibility of puddles or runs on the surface and ensure a properly penetrated finish.

Important Things to Keep in Mind

Weather Conditions

• Be sure to apply under very dry conditions only. Application to a damp surface may cause a hazy appearance and could cause lifting. Do not apply if rain is expected within 12 hours following application.
• Air and surface temperature should be between 50º and 90ºF for 24 hours following application. This will ensure proper product penetration.

• It's a good idea to stir the sealer slowly and thoroughly before and during the application process. Do not shake-avoid "whipping" air into the sealer.
• For damp or inclined areas that tend to get slippery, or where traction is important, add H&C^® SharkGrip^TM Slip Resistant Additive to your sealer.

• Do not thin.

• Before applying your coating, make sure you have followed the proper surface preparation methods for the surface you are coating.
• For horizontal applications, after surface prep, sweep the surface with a stiff broom to remove any remaining residue.

• Cleanup is easy-simply use mineral spirits or xylene, which you can find at your local home improvement store.

Application Methods for Bare Surfaces (cured for a minimum of 45 days)

First Coat:

• If your surface has corners or edges, coat those with your brush first to assure complete coverage of the sealer.
• Using your roller, evenly apply the first coat to the rest of your surface, working in one direction.
• Let it dry at least 4 hours before applying the second coat.
• Be careful not to overwork the product. If the coating has partially dried, overworking it could cause it to lift from the surface.

Second Coat:

• For best coverage, use your roller and apply the second coat in the opposite direction of the first coat (i.e., North to South if you applied your first coat East to West).
• Two coats of H&C^® Clear 23 Sealer are sufficient.

Application Methods for Topcoating over Silicone Acrylic Concrete Sealer

• Using your roller, evenly apply one coat over the entire surface, working in one direction.
• One coat is sufficient.
