POLIBRID® 705 is a tough, flexible and resilient elastomer used as a protective coating or lining for concrete, steel and other surfaces. It is a top-of-the-line product with a versatile and consistently successful track-record in critical applications for nearly every industry.

POLIBRID 705 provides the ultimate in corrosion protection for concrete or steel in potable water service. Protects against microbiologically induced corrosion (MIC), making it ideal for municipal wastewater applications. Geotextile fabrics may be embedded within the coating to produce reinforced, bonded geomembrane linings. Suitable for a wide range of industrial applications, including:

Potable Water Treatment & Storage

Secondary Containment Basins

POLIBRID 705 requires the use of specially designed, plural-component high-pressure airless spray machines for application. 

Standard equipment typically includes a GRACO® "Hydra-Cat" 45:1 fluid-to-air ratio air motor, a King air motor with triplex bottom on a 2A:1B fixed-volume ratio, heated hoses, drum heaters, suction feed system from 50 gallon steel drums (feed pumps not required in most cases), a recirculation system, GRACO® R-A-C III or IV spray tips from 0.021" to 0.035", stroke counter and automatic high-pressure shut-off system.

Other set-ups may be necessary and many options are available. Industrial painting contractors interested in becoming Qualified Polibrid Applicators must own the proper spray equipment and undergo on-the-job technical training by a factory-approved technical service representative!

Concrete

Allow 28 day cure for new concrete. Decontaminate per ASTM D-4258, then abrasive blast clean per ASTM D-4259 to produce surface profile similar to coarse sandpaper. Eliminate leaks and infiltrations and remove standing water. Resurface areas with excessive cavities (bugholes) or exposed aggregate using a high-strength, rapid-cure, zero-shrinkage resurfacing product. Wherever possible, geotextile fabric may be embedded within two layers of the coating to bridge, rather than resurface cavities, thereby eliminating the need for resurfacing compounds. Apply nominal 5 mils (125µ) POLIBRID 670S Epoxy Primer, before topcoating with POLIBRID 705. Concrete may be damp to the touch, however, surfaces must be free of condensation and visible moisture. Vacuum to dust-free condition before priming.

Carbon Steel

For direct-to-metal applications, decontaminate surface per SSPC SP-1 "Solvent Cleaning" if needed, then abrasive blast clean per SSPC SP-10 "Near-White Condition" to produce a nominal 3 ½ mil (88µ) surface profile. Remove flash rust per SSPC SP-7 "Brush-Off Blast Cleaning". Substrate must be dry and dust free before coating. Application to wet surfaces is not recommended.

Health & Safety

AVOID SKIN CONTACT! Wear chemical goggles as minimum eye protection, use impermeable gloves and cover all exposed skin. Do not allow contaminated clothing to contact skin. Use properly fitted organic vapor respirators and adequate ventilation. Wash hands before eating, smoking or using washroom. Follow precautions in CFR Title 29 (OSHA) and all pertinent local, state & federal health, safety and environmental regulations. Read, understand and fully comply with recommendations made in Material Safety Data Sheets (MSDS) supplied for individual coating components!

Confined Spaces

COMPLY WITH PERTINENT OSHA REGULATIONS RELATIVE TO WORK IN CONFINED SPACES! Provide forced air ventilation. Workers must use carbon monoxide filtered breathing air-line respirators. If flammable vapors are present, use only non-sparking tools and equipment.

First Aid

SKIN CONTACT: Wash thoroughly with plenty of soap and water.

EYE CONTACT: Immediately flush with fresh clean water for at least fifteen (15) minutes and get specialized medical attention promptly.

INHALATION: Remove to fresh air and provide oxygen.

INGESTION: Immediately call a physician or poison control center. DO NOT INDUCE VOMITING!
