A high silver content allows these surface fillers to conduct electricity and heat. Use them to fill gaps and rebuild missing material on electrical connections or to assemble new components.

Mix these two-part epoxy surface fillers to create a strong repair in wet environments or underwater.

For quick repairs, these epoxies begin to harden in 6 minutes or less.

Pull off a small piece of putty and stick lightweight objects to a surface.

Also known as thumb-grade caulk, this forms a non-hardening, moisture-resistant seal that remains pliable.

Mix a small amount of water-based paint with this caulk to match the color of your surface.

Made from silicone, these sealants are RTV (room-temperature vulcanizing).

Resistant to mold and mildew, these sealants are well suited to high-humidity environments.

Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.

Also known as neutral-cure sealants, these won't discolor copper, brass, and concrete.

Apply these sealants in cold temperatures, on wet surfaces, and even through running water.

Thinner than non-sagging sealants, this sealant flows easily into cracks and has a smooth finish.

A combination of hardness and surface tension makes these sealants resistant to punctures, cuts, and abrasion.

Apply these sealants in cold temperatures, on wet surfaces, and even through running water.

Made from silicone, these sealants are RTV (room-temperature vulcanizing). They combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility.

Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.

Thinner than non-sag sealants, these flow easily into cracks and have a smooth finish.

These non-sagging sealants will not drip while hardening on vertical and overhead surfaces.

Press this pliable rope into place to hold glass in window frames and seal leaks.

These sealants don't degrade in sunlight.
