Structure Guard®-QS is a quick spray, 100% solids, high-build epoxy coating formulated to provide long-term corrosion protection and structural enhancement for manholes, pump stations, treatment plants or any wastewater infrastructure subject to high levels of corrosion and/or abrasion. Structure Guard-QS sets fast for a quick return-to-service in the most aggressive and turbulent environments. It finishes smooth to enhance flow and is utilized as an interior or exterior pipe lining.

With Structure Guard®-QS, only 1 coat is needed to attain finished thickness. If additional coats are called for they must be applied before the previous coat has completely cross-linked, typically for 12 hours @ 72°F (higher temperatures/humidity will shorten this window). If re-coating is needed, brush blast before applying the next coat. Before re-coating, clean and dry surface thoroughly to remove all contamination, including amine blush or condensation. Small areas may be abraded by sanding or wire brushing.

The same requirements apply when overlapping seams of adjacent coating sections to create a continuous protective film. If the coating surface to be overlapped at the seam cannot be brush blasted, use a non-impact means, such as power brushing or sanding, to create adequate mechanical profile.

Structure Guard-QS will yield theoretical coverage of 20 sq. ft per gallon @ 80 mils thickness. Actual surface coverage will depend on substrate porosity and roughness. A wet film thickness gauge may be used to determine actual coating thickness.

Coating performance is largely determined by the degree of surface preparation. MORE IS BETTER.

EXISTING CONCRETE AND MASONRY substrates must be prepared  in a manner that provides a uniform, sound, clean, neutralized surface with sufficient profile suitable for the specified coating. The substrate must be free of all contaminants, such as oil, grease, rust, scale or deposits and have a surface profile equivalent to a CSP3 to CSP5 in accordance with ICRI Technical Guideline No. 03732. This

can generally be achieved by abrasive blasting, shot blasting, high pressure water cleaning, water jetting, acid etch, hot water/steam cleaning or a combination of methods.

NEW CONCRETE AND MASONRY SUBSTRATES must be profiled to achieve a CSP4.

STEEL surfaces may require “Solvent Cleaning” (SSPC-SP 1) to remove oil, grease and other soluble contaminants. Chemical contaminants may be removed according to SSPCSP 12/NACE No. 5. Identification of the contaminants, along with their concentrations, may be obtained from laboratory and field tests as described in SSPC-TU 4 “Field Methods for Retrieval and Analysis  of  Soluble Salts on Substrates”. Surfaces to be coated should then be prepared according to SSPC-SP 5/NACE No.1 “White Blast Cleaning” for immersion service or SSPC-SP 10/NACE No. 2. “Near White Blast Cleaning” for all other service. In certain situations, an alternate procedure may be to used such as high (>5,000 psi) or ultrahigh (>10,000 psi) pressure water cleaning or water cleaning with sand injection. The resulting anchor profile shall be 2.5-5.0 mils and be relative to the coating thickness specified.

Structure Guard^® – Water  is a 100% solids epoxy coating made for plural component spray application. NSF 61 certified for pipe as small as 4” diameter and tanks 50 gallons and larger. With a 25 minute pot life and extended re-coat time, Structure Guard – Water is the perfect product to coat long pipelines and large water tanks.

Chimney Guard is a 100% solids Epoxy/Urethane hybrid designed to provide a highly flexible and securely bonded seal prepared to address heavy traffic loading, extreme freeze thaw and infiltration.

Concrete: Existing concrete must be hydro blasted using a turbo tip at 4000psi until all loose concrete is removed. New concrete must be cured for 28 days prior to application of Chimney Guard. Abrasive blast, in accordance to SSPC-SP13/NACE 6, must be performed prior to application of Chimney Guard.

Steel: Near-White Blast SSPC-SP10/NACE 2. Sandblasting is required when applying Chimney Guard to manhole frame.

All surfaces must be clean and free from oil, grease and other contaminants!

Fill all voids and cracks greater that 1/8 inch with Quadex™ Hyperform™. Wait one hour before applying Chimney Guard. Quadex AluminaLiner will need a full 24-hour cure prior to the application of Chimney Guard. Quadex GeoKrete® and QM-1s™ will need a full 5-day cure prior to the application of Chimney Guard. When Quadex Structure Guard® has been used to line the manhole, Chimney Guard can be applied directly to Structure Guard within 8 hours, or as soon as Structure Guard has become tack free. After 8 hours, Structure Guard must be abraded with 80 grit sand paper before applying Chimney Guard.

All surfaces must be dry before applying Chimney Guard.

Use Acetone to clean tools.

Flex Guard^® is a 100% Solids Flexible Urethane/Epoxy hybrid. The extreme Flexibility of Flex Guard makes it the best solution for the most extreme conditions. A 100-150% elongation allows it to be applied where other coatings fail.

Flex Guard exhibits excellent adhesion to steel and concrete; providing superior protection for tanks that typically experience freeze thaw and temperature fluctuation.

Flex Guard is available in 5 gallon pails and 55 gallon drums.

Flex Guard will yield theoretical coverage of 12.5 sq. ft per gallon @ 125 mils thickness. Actual surface coverage will depend on substrate porosity and roughness. A wet film thickness gauge may be used to determine actual coating thickness.
