RIGHT-POXY LOW MOD is a two component, 100% solids, low modulus, moisture insensitive epoxy binder with properties which makes it suitable for use in applications where stress relief and resistance to mechanical and thermal movements are required. RIGHT-POXY LOW MOD is formulated for low temperature applications, or where rapid cure is required.
RIGHT-POXY LOW MOD is designed for use as a binder for overlays or non-skid surfaces on concrete decks and floors in parking decks, bridges, factories, warehouses, loading docks and related applications. RIGHT-POXY LOW MOD is also used in nosing repair applications.
RIGHT-POXY LOW MOD is a two component, 100% solids, epoxy compound.
RIGHT-POXY LOW MOD complies with requirements of ASTM C881-99, Type III, Grade 1, Class B and AASHTO M-235, Type III, Grade 1.
Clear, Light Gray, Dark Gray, and Tile Red.
Concrete must be structurally sound, dry, free of grease, oils, coatings, dust, Chemical Liquids and other contaminants. Remove oil, grease smear and asphalt residue with trisodium phosphate or a strong detergent. For heavy oil contamination use steam cleaning in conjunction with a strong emulsifying detergent. Surface laitance must be removed. The preferred method of surface preparation is abrasive blasting. If it is not possible to abrasive blast, acid etch with 15% hydrochloric acid solution.
Follow by pressure washing with copious amounts of water to neutralize the surface. The pH of the surface should be checked according to ASTM D4262 after washing. Rinse thoroughly with potable water. After cleaning, repair defective concrete, honeycombs, cavities, joint cracks, voids and other defects by routing to sound material and patching as needed. Smooth precast and formed concrete surfaces must be cleaned, roughened and made absorptive by abrasive blasting or shotblasting. Following surface preparation, the cleaned surface should pull
concrete when tested with an Elcometer or similar pull tester (ASTM D4541). Before application of the coating, use the “Visqueen test” (ASTM D4263) to evaluate moisture level in concrete. New Concrete: Allow to cure for a minimum of 28 days. (Consult Technical Service if earlier times are required). Prepare surface as recommended above. Old Concrete: For rapid curing patching, use a mortar of RIGHT-POXY LOW MOD and clean aggregate. If portland cement patching materials are used, allow the patch to cure for 28 days before coating. (Consult Technical Service for appropriate patching materials if earlier application is required.) After patching, a light brush blast is recommended prior to coating.
Using a low speed drill motor and a “Jiffy” type mixer, mix the A & B RIGHT-POXY LOW MOD components separately for approximately 1 minute.
Binder: Combine one part by volume of “A” with one part by volume of “B” and mix thoroughly. Scrape the bottom and sides of mixing container, at least once. Mix just enough material that can be used within the working life. Do not aerate the mix.
Broadcast Method: Apply mixed RIGHT-POXY LOW MOD binder to the prepared surface using roller, notched squeegee or spray equipment. Eliminate any puddles with a quick light roller pass. Immediately broadcast clean, dry aggregate to full saturation until no wet spots appear. After the binder has cured, broom or vacuum excess aggregate. Repeat the procedure to build overlay thickness. For easier cleaning an optional seal coat of RIGHT-POXY LOW MOD may be applied. A more textured, and higher skid resistant sealed surface is obtained if RIGHT-POXY LOW MOD LV is used as the seal coat.
Troweldown Applications: RIGHT-POXY LOW MOD mortar can be applied by trowel. Neat resin should be used as a prime coat prior to application of the mortar. Consult Technical Service for application recommendations.
Aggregate for Skid Resistant Overlay: The recommendedaggregate for heavy duty applications (high traffic bridge decks, parking deck turn lanes, etc.) is #8 or #9 Basalt, containing at least 10% aluminum oxide as supplied by ____. For other applications, or where specified, silica sand aggregate may be used.
