ResSeal is a line of high performance epoxy based sealants and coatings manufactured by ResTech Environmental Products, a Texas based company. The brand centers on a self leveling, two part epoxy system built for rust prevention and corrosion control on metal, concrete, and other surfaces found throughout mechanical rooms and industrial sites.
Product Lines
SupplyHouse carries several ResSeal formulations, including ResSeal Multipurpose, ResSeal Flex, and ResSeal Paste Grade, packaged in gallon kits, bags, and cartridges. Multipurpose is a 100 percent solids, VOC free epoxy suited to drain pans, cooling towers, and general HVAC equipment, while the Flex formulation offers elastomeric flexibility for joints and substrates like asphalt and concrete, and the Paste Grade trowelable version is built for vertical or overhead repairs needing extra chemical resistance.
Why Contractors Specify ResSeal
HVAC and mechanical contractors turn to ResSeal when a leaking drain pan, cooling tower basin, or corroded metal surface needs a durable repair without pulling the equipment out of service for an extended period. Because the epoxy cures underwater and bonds to concrete, stainless steel, metal, fiberglass, and wood, technicians can apply it across a wide range of job site conditions using a single product family instead of switching between multiple specialty sealants.
How to Choose ResSeal Products
Selecting a ResSeal formulation depends mainly on the substrate and the shape of the repair. Flat horizontal surfaces such as drain pans or cooling tower basins are generally a good match for the self leveling Multipurpose formula, while vertical walls or overhead repairs call for the trowelable Paste Grade version so the material stays in place while curing. Joints, expansion cracks, or surfaces that flex under temperature changes are better suited to the Flex formulation, and technicians should confirm the container size needed for the repair area before starting the job.
Frequently Asked Questions
What kind of repairs is ResSeal designed for?
ResSeal is formulated for sealing leaks and restoring corroded surfaces on drain pans, cooling towers, pipelines, and other HVAC and mechanical equipment.
Can ResSeal be applied on wet or underwater surfaces?
Yes, ResSeal is designed to cure underwater and bond to substrates including concrete, stainless steel, metal, fiberglass, and wood.
What is the difference between ResSeal Multipurpose and ResSeal Paste Grade?
Multipurpose is a self leveling formula suited to flat, horizontal surfaces, while Paste Grade is a trowelable version built to stay in place on vertical or overhead repairs.
Is ResSeal a VOC free product?
The Multipurpose formulation is a 100 percent solids, VOC free epoxy system.
What formulation should a technician choose for a joint that flexes with temperature changes?
ResSeal Flex is the elastomeric formulation built for joints and substrates that need flexibility rather than a rigid bond.
