PRODUCT DESCRIPTION

H&C® Natural Look Clear Sealer is a clear water-based,

siloxane water repellent that is designed to protect bare

concrete driveways and masonry surfaces. Provides a long

cracking, spalling, staining and other damage related to water

intrusion.

FEATURES & BENEFITS

• Water-Based formulation.

• Protects against damaging freeze/thaw cycles.

• Reduces intrusion of water, de-icing salts and other

contaminants.

• Penetrates deeply for long-lasting protection.

JOBSITE TEST SECTION

Due to the wide variety of substrates, preparation methods,

application methods and environments, it is important to test

the product in an inconspicuous spot for adhesion and

compatibility prior to full-scale application.

LIMITATIONS

Won’t keep water out of cracks, defects or open joints.

Not recommended for below-grade application.

Not suitable for application to gypsum or other non-masonry

surfaces. Not for use on cinder block due to porosity issue

SURFACE PREPARATION

New Concrete: Allow new concrete to cure at least 28 days.

Concrete surfaces should be able to absorb water. To test

absorption, spray various sections of the surface to be stained

with water. If the water does not absorb rapidly, then acid

etch the surface using an etching solution, following label

instructions. After proper etching, the surface should feel like

120-grit sandpaper. If not, then etch again. Mechanical

abrasion methods may be necessary to achieve proper profile.

Do not apply the stain until all surfaces are porous. Allow all

surfaces to dry at least 24 hours before staining. Prepared

concrete must have a pH of 6 to 10.

Existing and Previously Painted Concrete: All concrete must

be porous, clean, dry and free of grease, oil and other

contaminates.

To spot clean, use a cleaner degreaser,

following label directions. If mold, mildew, or fungus is

present, kill and remove with a solution of 1 cup household

bleach to 1 gallon of water. If surface has been previously

painted, remove all old, peeling, flaking paint by rough sanding

in a circular motion to ensure adhesion of H&C® Natural Look

Clear Sealer. Rinse away sanding dust before stain application.

Wear protective eyewear, waterproof gloves, and protective

clothing. Quickly wash off any of the mixture that comes in

contact with your skin. Do not add detergents or ammonia to

the bleach/water solution. DO NOT ETCH PREVIOUSLY

PAINTED SURFACES.

*WARNING! Removal of old paint by sanding, scraping or other means may

generate dust or fumes that contain lead. Exposure to lead dust or fumes may

cause brain damage or other adverse health effects, especially in children or

pregnant women. Controlling exposure to lead or other hazardous substances

requires the use of proper protective equipment, such as a properly fitted

respirator (NIOSH approved) and proper containment and cleanup. For more

information, call the National Lead Information Center at 1-800-424-LEAD (in

US) or contact your local health authority.

Repair: For the best waterproofing protection on vertical and

horizontal concrete and masonry surfaces, use a patch and

repair to address spalled concrete. Please note that patching

compounds will generally be visible through clear coatings.
