Stop active leaks of up to 50 gallons per minute in concrete, brick, and stone. These crack fillers begin to harden within seconds to create a permanent fix that won't shrink. When fully cured they create a seal that can withstand pressure of up to 2,000 psi. Apply with a dispensing gun (sold separately). The size listed is the combined total of the two parts. A mixer nozzle is included.

Fill in and shape horizontal, vertical, and overhead concrete surfaces, such as steps and columns.

Keep the surface of your porcelain fixtures looking like new.

Filler repairs large chips and cracks. Sand and finish with glaze.

Glaze touches up small chips and scratches.

Mix this two-part epoxy—a resin-aggregate blend and a pigmented hardener—to create a grout that resists chemicals, such as acids, alkalies, salt water, and common solvents and cleaners. Its lightweight formula makes this grout easy to spread. Use in horizontal or vertical joints—grout won’t sag or shrink. Apply with a grout float. It can be cleaned up with water when wet; it doesn’t require a sealer once it cures. The size listed is the combined total of the two parts.

Used on ceramic, concrete, and stone floor and wall tiles, grout consists of fine sand, masonry cement, and coloring. Apply with a grout float.

Acrylic grout does not require mixing. It resists shrinking, cracking, and staining.

Temporarily stabilize objects on flat surfaces with this clear adhesive gel. It removes cleanly from most surfaces with a twist, and it won't dry out so it can be used again.

Caulk is non-sagging, so it won't drip from vertical and overhead surfaces.

Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement a sealant can sustain. Caulk is best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.

Mix a small amount of water-based paint with this caulk to match the color of your surface. Caulk is non-sagging, so it won't drip from vertical and overhead surfaces.

Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. Sealants that are good for joining dissimilar materials also work well in environments with wide temperature fluctuation.

Also known as neutral-cure sealants, these won't discolor copper, brass, and concrete. They’re non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone, sealants are RTV (room-temperature vulcanizing).

Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. Sealants that are good for joining dissimilar materials also work well in environments with wide temperature fluctuation.

Sealants that cannot be sold to California exceed local regulatory limits on VOCs (volatile organic compounds).

Compliant with ASTM E-595, these sealants produce almost no volatile materials in a vacuum. They’re made of silicone, so they’re RTV (room-temperature vulcanizing).

Elongation indicates flexibility—the higher the value is, the more a sealant can stretch.

Meeting requirements for semiconductor, biomedical, and electronics clean rooms, these sealants won’t contaminate air and surfaces. Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain.

These sealants are non-sagging, so they won't drip from vertical and overhead surfaces.

Elongation and joint compression/expansion tolerance indicate flexibility. For joints between dissimilar materials and in environments with wide temperature fluctuation, choose a sealant with a higher elongation or joint compression/expansion tolerance. For high-wear applications, choose a harder sealant for the most abrasion resistance.

Form seals that resist punctures, cuts, and abrasion to withstand heavy wear and tampering. These sealants are non-sagging, so they won't drip from vertical and overhead surfaces.

Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.

Apply these sealants in cold temperatures, on wet surfaces, and even through running water. They are structural sealants that combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility. Sealants are non-sagging, so they won't drip from vertical and overhead surfaces.

Sealants that cannot be sold to California exceed local regulatory limits on VOC (volatile organic compounds).

Impervious to the swelling effects of oils, fuels, and solvents, use this high-strength silicone sealant to assemble and repair fuel systems and tanks. Silicone forms a tough, rubbery, UV-resistant seal that remains flexible over time. It's non-sagging, so it won't drip from vertical and overhead surfaces. Also known as RTV (room-temperature vulcanizing).
