DESCRIPTION: BVS GEL-WELD Injectable Epoxy System is a two-component, self-mixing 100% solids, high-viscosity, fast-setting solvent-free, high-strength compound designed for general concrete repair work. The product has a gun-grade consistency that is used for filling cracks in vertical, overhead and horizontal structures. BVS GEL-WELD resists industrial chemicals and is moisture insensitive. Because the product is solvent-free, it offers VOC compliant installations. BVS GEL-WELD’S high viscosity, makes it easy to apply. This is of great importance when using it as an adhesive since it fills all gaps between the surfaces to be bonded while a fluid epoxy adhesive will run out thereby reducing the bond area. To make small patches in concrete structures, it is often more convenient to use BVS GEL-WELD than to prepare an epoxy mortar using silica sand. BVS GEL-WELD uses a unitized, dual cartridge system … the epoxy mixes as it is applied.

USES: BVS GEL-WELD Injectable Epoxy is ideal for filling cracks in vertical, overhead and horizontal concrete surfaces, due to its consistency. It is also applicable for concrete patching, topping, grouting, spall repairs, adhesive and bolt anchoring projects. BVS GEL-WELD will bond cured concrete, wood, plastic or metal to concrete.

SHELF LIFE: Two years in unopened, damage-free containers stored in a dry environment between 40º-95ºF (4º-35ºC).

• Do not thin epoxy with solvents.
• Do not use for sealing cracks while under hydrostatic pressure or spray without consulting BVS Technical Service first.
• Never warm epoxy over direct heat. Warm cold epoxy by placing containers into hot water. The preferred method is to store the epoxy in a warm room prior to use. The resin and hardener must be between 60º and 85ºF (16º-29ºC) at the time of mixing and is not recommended for use when the pavement temperature for the past 24 hours has been below 40ºF (4ºC).
• For exterior, on-grade applications, consult BVS Technical Service first.
• Read and follow application data, precautions and Material Safety Data information.

SURFACE PREPARATION: AII surfaces to be bonded must be free of standing water, and completely clean of dirt, rust, curing compounds, grease, oil, paint, and unsound materials which would prevent a solid bond. Concrete should be cleaned by sandblasting to a sound surface. Vacuum or blow dust away with compressed air. Concrete contaminated with only laitance and dirt, other than grease or oil, may be acid etched. Smooth surfaces, such as wood, or cured epoxy, require sanding or other mechanical abrasion. Exposed steel surfaces should be sandblasted and vacuumed clean; if not possible, degrease the surface and use sandpaper or a wire brush to reveal continuous, bright metal.

MIXING: Unit must be between 60º-85ºF (16º-29ºC) at time of mixing. (See LIMITATIONS). Consult and follow mixing and application directions included with unit. Load into Dual Cartridge Gun. Prior to using, dispense and discard a 6" to 12" (15.24cm to 30.48cm) bead of material until a uniform, streak-free color is achieved. Final mixture should be a uniform gray paste without any white or black streaks. Place the mixed epoxy as soon as possible. Work life depends on the temperature and the mass. Unused portion of cartridge may be recapped for future use. To use remaining contents in cartridge, a new static mixing tip must be used.

METAL ANCHORS IN PREFORMED HOLES IN CONCRETE: Preformed holes should be approximately ¼" (6.35mm) larger in diameter than the anchor bolt diameter. The depth of the hole should be 10-15 times the bolt diameter. Fill the hole about half way with the mixed epoxy and place the bolt, dowel or rebar. Top off with more epoxy and finish.

CRACKS IN VERTICAL OR OVERHEAD STRUCTURES: Do not use in cracks wider than ½" (12.7mm) maximum.

PATCHES IN CONCRETE STRUCTURES: The BVS GEL-WELD makes a high-strength material for patching, topping, grouting and repairing spalls and other defects in concrete. Average thickness of the patch or topping should be no greater than ¼ to ½" (6.35mm to 12.7mm) per lift.

OTHER BONDING: To bond cured concrete, wood, plastic or metal to concrete, apply not less than a 1/64" (.40mm) layer to the prepared surface and join together immediately. No firm clamping pressure is necessary beyond what will hold the parts in place. When bonding fresh concrete to cured concrete, apply BVS GEL-WELD at approximately 85-100 sq. ft. per gallon (2.1-2.4 sq. meters per liter). NOTE: Cured concrete surfaces to be bonded to should be at least 28 days old.

CLEANUP: Tools and equipment should be cleaned immediately with Toluene or Xylene. Clean equipment away from heat, sparks and open flame and avoid breathing vapors or allowing epoxy-containing solvent to contact skin. Should this material come in contact with the skin, wash thoroughly with soap and water.
