PRODUCT DESCRIPTION

Proudi Sealer SB is a high-performance thermoplastic acrylic resin floor coating and concrete curing agent. It provides a deep-penetrating, non-yellowing, scuff-resistant finish. Available in both clear glossy and matte finishes, it is ideal for sealing, curing, and protecting a variety of concrete surfaces.

APPLICATIONS

• Sealing, curing, and protective coat for colored and uncolored concrete surfaces.

• Ideal for stamped concrete, chemically stained concrete, exposed aggregate concrete, and masonry surfaces.

• Protects interlock, porous brick, natural stone, plaster, wood, and other absorptive materials from moisture and oil penetration.

• Suitable for both interior and exterior applications.

PHYSICAL PROPERTIES

• Volume Solids: 36%

• Pull Off Adhesion (ASTM D4541): 4.8 MPa (Substrate Failure)

• Chemical Resistance (ASTM D543:95, 7 days):

  • Acetic Acid (10%) – Excellent

  • Sodium Hydroxide (10%) – Excellent

  • Hydrochloric Acid (10%) – Excellent

• Moisture Resistance (ASTM C156): 0.313%

• Dry Time (21°C, 50% RH):

  • 30 min to touch dry

  • 1 hour recoat time

  • 4 hours foot traffic

  • 24 hours for heavy traffic

  • 48 hours for full cure

• Film Thickness: <100 microns

• Thinning: Not required; use organic solvents for cleaning.

ADVANTAGES

• Beautifies surfaces and enhances appearance.

• Highlights the color and texture of stamped concrete and enhances antique effects.

• Seals and dust-proofs concrete, stone, brick, and other surfaces.

• Protects surfaces from stains caused by oils and food spills.

• Formulated for both interior and exterior use.

• Non-yellowing and highly UV resistant.

• Allows concrete to breathe.

• Available in matte and gloss finishes.

COVERAGE

• First Coat: 4 m²/L

• Second Coat: 5 m²/L

• Minimum two coats recommended. Coverage rates vary depending on surface porosity, texture, and other conditions.

LIMITATIONS

• Do not apply if ambient temperature is expected to drop below 3°C within 24 hours.

• Avoid application if rain, dew, or water exposure is expected within 24 hours after application.

• Avoid application in direct sunlight or during high winds.

• For matte finish, apply a glossy coat first.

SURFACE PREPARATION

• Surfaces must be dry, clean, and free of grease, oil, dirt, wax, and other contaminants.

• Use appropriate cleaning agents and ensure thorough rinsing before application.

• Scraping, wire brushing, sanding, or power washing may be necessary for previously applied coatings.

• Allow surfaces to dry for at least 24 hours.

• Do not use soap or detergent for cleaning, as residues may prevent adhesion.

APPLICATION INSTRUCTIONS

• Application: Apply full strength. Avoid application in direct sunlight or during strong winds. Apply early in the morning or late in the evening on hot days.

• Use a synthetic or nylon-bristled brush. For smooth surfaces, use a 6 mm nap roller. For textured surfaces, use a 9-12 mm nap roller.

• Apply two coats for maximum protection, especially on unpainted and highly porous surfaces.

• Apply a coat of glossy grade before applying the matte grade of sealer.

• Allow 24-48 hours drying time between coats.

• Foot traffic is allowed after 24 hours, heavy traffic after 72 hours.

SAFETY PRECAUTIONS

• DANGER: Flammable vapor and liquid. Contains aromatic hydrocarbons.

• Harmful if swallowed or inhaled. Causes eye irritation.

• Use in a well-ventilated area with proper respiratory protection (NIOSH TC-84A approved organic vapor respirator).

• Wear goggles, protective clothing, and vinyl gloves when handling.

• Keep away from heat or ignition sources.

FIRST AID:

• Eyes: Flush immediately with fresh water.

• Skin: Wash with soap and water.

• Inhalation: Leave the area if breathing difficulty occurs.

• Ingestion: Give large amounts of water and induce vomiting. Seek medical attention.

MAINTENANCE

• Inspect treated surfaces periodically for thin or worn areas. Reapply sealer as necessary.
