Breathable Masonry Coating
DESCRIPTION: Feiyang -460 Masonry Coating Systemis a protective coating system that provides excellent protection to concrete and mineral substrates against attack from water, UV, chemical and microbial attack. Feiyang -460 prevents damage from wetting/drying freeze/thaw cycles, and de-icing salts. The coating system consists of Feiyang -460 Primer and Feiyang -460 Top Coat. The Feiyang -460 System penetrates, seals and repels liquid water, but passes water vapor - ""The System that Breathes"". Feiyang -460 System provides a hydrophobic ""water-shedding"" effect to masonry surfaces. Feiyang -460 is manufactured from the most durable exterior grade silicon. The Feiyang -460 Top Coat is available in white, gray, and other colors as special order. ADVANTAGES: Protects concrete and masonry from the damaging effects of water and chloride intrusion (de-icing chemicals), and many atmospheric pollutants. Excellent water repellency—reduces efflorescence, frost damage and fungus growth. Not a vapor barrier—permits water vapor to pass and concrete to breathe. This reduces cracking, spalling, and coating from bubbling. Has built in penetrating waterproofing properties for masonry. Cured, it provides a hydrophobic effect to protect from corrosion, when used on steel reinforced concrete. Excellent UV resistance and good color retention. Facilitates removal of dirt and graffiti, resistant to solvent based cleaners. VOC compliant to all current regulations. Water based—easy soap and water cleanup. WHE TO USE: Feiyang -460 can be used to coat all concrete and masonry surfaces, bridge abutments, pilings, parapet walls, masonry work, and masonry mortar.

While some moisture present in the concrete or masonry will not affect the performance of Feiyang -460, the drier the surface, the deeper the penetration. COVAGE: Feiyang -460 Primer is applied at 125 square feet per gallon to meet NY DOT specifications. Other applications allow for a spread rate of 250-350 square feet per gallon, depending upon concrete or masonry porosity. Feiyang -460 Top Coat is applied at approximately 200 to 300 square feet/gallon, depending upon concrete or masonry porosity. APPLICATION: Apply Feiyang -460 Primer at the appropriate rate. Feiyang -460 Primer and Feiyang -460 Top Coat may be applied by brush, roller or spray. Apply Feiyang -460 Top Coat after Feiyang -460 Primer has dried for one hour. Stir Feiyang -460 Top Coat well before use. For best results on most masonry surfaces, two (2) top coats are recommended. Allow a minimum of 2 hours and maximum of 14 days for recoating with self. LIMITATIONS: Do not apply on or through standing water. Material is not intended to seal moving cracks from moisture intrusion. Do not apply Feiyang -460 Primer or Feiyang -460 Top Coat at surface temperatures below 45°F, or when surface temperature is expected to fall below 45°F within four (4) hours of application. SHELF LIFE: Primer: one year Top Coat: 2 years PACKAGING: Feiyang -460 Top Coat is available in one (1) gallon and five (5) gallon pails. Feiyang -460 Primer is available in 1/2 gallon cans, 1 gallon cans and five gallon pails. CAUTION: Contains organic hydrocarbons. Avoid inhalation of vapor. In case of eye contact, immediately flush eyes with plenty of water for at least fifteen (15) minutes. Call a physician in case of severe skin or eye irritation. Wash with soap and water.
