System 44 Concrete Repair Mortars

DECK-TOP 47, 47-RC Thin Resurfacers for Concrete Floors and Decks (Regular & Rapid-Cure Formulas)
DECK-TOP 47 and 47-RC are two-part, latex modified, concrete patching and resurfacing compounds designed for high-performance in thin-section topping applications. DECK-TOP applications of 1/8″ to ¼” thickness withstand heavy vehicular traffic, impact and vibration without loss of adhesion or rapid wear.

AQUEPOXY 250 Waterborne Immersion-Grade Epoxy
High-gloss, chemical and water-resistant waterborne epoxy coating for floors, walls, machinery surfaces. Suitable for continuous water immersion after cure, may be applied to damp or “green” concrete.

FLEXI-GARD 500-N-FLX Flexibilized Novolac Epoxy
FLEXI-GARD 500-N is a 100% solids, odorless, VOC-Compliant epoxy coating system designed for maximum resistance to chemical spillage and immersion, heavy industrial traffic and elevated temperatures.
FLEXI-GARD 500-N is a 100% solids, odorless, VOC-Compliant epoxy coating system designed for maximum resistance to chemical spillage and immersion, heavy industrial traffic and elevated temperatures.

FLEXI-GARD 500-S Low Viscosity Epoxy Coatings
100% solids, odorless, USDA-accepted clear or colored floor coatings Also available in 90% solids (500S-90) for easy handling and low cost. Withstands a wide range of chemical exposures.

FLEXI-BOND 540 Epoxy Bonding Agent (New Concrete to Old Concrete)
FLEXI-BOND 540 is a two component, 100% solids, moisture-insensitive epoxy bonding agent. Application of FLEXI-BOND 540 to wet or dry, properly prepared substrates assures tenacious adhesion of new toppings, patching compounds and tile bedding mortars when used in accordance with instructions. It may also be applied to steel, tile, wood and fiberglass. It can be used as a combination waterproof barrier and bonding agent when applying new concrete toppings over old concrete. It can be used to improve adhesion of tile bedding mortars to existing concrete, or may be used directly for tile bedding in combination with very fine sand. It can be used to prime and waterproof steel reinforcement prior t application of patching compounds or concrete pouring while improving adhesion of these materials. It can be used to penetrate and consolidate low strength floors , such as asbestos-cement or cinder concrete, and to improve adhesion of new toppings or patching compounds to same. It can be used to promote adhesion of concrete, bedding mortars or toppings to non-cementitious substrate, such as tile, plywood decking, or steel plate.

FLEXI-MATRIX 545 Epoxy Polymer Concrete
FLEXI-MATRIX 545 is a two component, 100% solids, moisture-insensitive epoxy used for making high-strength chemical resistant polymer concrete. FLEXI-MATRIX 545 may be used under wet or dry conditions, or even underwater, to provide durable, high-strength toppings, patches, floors, walls or other structural elements, when used in accordance with the instructions. It may be applied over concrete, steel, tile, wood, and fiberglass.

FLEXI- TOP 550 Overlayment and Resurfacing Mortar
FLEXI-TOP 500 & 555 are heavy-duty, 100% solids, odorless epoxy mortars far patching and topping of commercial, institutional and industrial floors.
FLEXI-TOP 555 is a versatile trowel-applied mortar used for patching or toppings of 1/4″ or more. Blended with specially graded aggregates, it forms a dry, trowelable mortar that can be applied by hand or power trowel. This mortar is then grouted and sealed with 100% solids resins to eliminate porosity and produce a dense, non-porous, slip-resistant finish.

Marine-FLEX 570 Underwater Grade/Submersible Epoxy
Marine-FLEX 570 Underwater Grade/Submersible Epoxy is a 100% solids, medium viscosity, moisture insensitive epoxy coating intended for heavy marine and wet industrial exposures. Marine-FLEX 570 CAN BE APPLIED UNDERWATER, as well as on wet, damp or dry concrete or steel surfaces exposed to air

FLASHEPOXY 580-Series Ultra-Fast & Low Temperature Adhesives / Acrylate-Epoxies
FLASHEPOXY 580-Series Ultra-Fast & Low Temperature Adhesives / Acrylate-Epoxies are 100% solids, low odor/toxicity, mercaptan-free formulation permits coating and patching down to -220F, for winter, refrigerator, freezer and fast-cure applications. Moisture tolerant, non-flammable, “0” VOC, non-shrink
