For the past 19 years we have been dedicated to offering our customers unbiased expertise, unparalleled service and our professional-quality, ready to use, concrete sealers, brick sealers, and concrete repair products.
Whether your intention is to dry out a damp basement, reduce radon levels, waterproof a brick chimney, prevent concrete dusting, or preserve the look of your outdoor concrete, our line of trusted, professional-grade penetrating concrete sealers will more than exceed your expectations!
When Performance Matters – No messy mixing, no sticky residues, our line of sealers are ready to apply upon delivery. Incomparable to anything available in stores, which sell film-forming sealers that will break down, peel, discolor, and most having to be reapplied annually. The RadonSeal pro-line of long lasting, penetrating, waterproofing sealers have an extensive and well proven history when quality and performance matter!
The chart and product information below will help you better understand how to select the proper penetrating sealer for your specific project. Surface porosity varies greatly and penetration of the sealers is not guaranteed. Testing is recommended to confirm that sealers are properly working. If you wish to discuss your particular project or have any questions regarding our products and their application please feel free to contact us to speak to or email a product technician.

The Permanent Solution to Concrete Waterproofing! Silicate-based, internal reactive sealer that penetrates up to 4 inches into concrete and chemically reacts with alkalis and hardens as a mineral. Using RadonSeal® is like injecting more cement into the pores! Once cured the sealer cannot be pushed out regardless of hydrostatic pressure. RadonSeal will provide your concrete the tightest seal against water, vapor and gases and will also harden the concrete making it more resistant to spalling, cracking, and dusting.
Common Use: Damp basements, foundation walls, concrete blocks, cinder blocks, slab-on-grade, damp concrete floors, concrete blocks, cinder blocks, sweating garage floor, deteriorated outdoor concrete, dusting concrete, limestone, sandstone foundation.
Product Information – 15-Year Waterproofing Warranty.
The best brick and masonry sealer on the market! Polyester/polyurethane based brick sealer. Penetrates 2 to 4 inches into porous materials, fills up the pores and hardens. Seals a wide range of porous materials regardless of their cement content or additives. It's like injecting epoxy into the pores. LastiSeal® leaves the surface paintable, except for latex and silicone. LastiSeal will also not change the surface appearance or the friction of the substrate.
Common Use: Bricks, brick walls, brick chimneys, porous brick veneer, pavers, porous stone, man-made stone, colored concrete, stamped concrete, pool decks, slump blocks, mexican pavers, outdoor concrete, CMUs, retaining walls, fiber-reinforced concrete.

Your One-Step Sealer and Stain! Polyester/polyurethane based concrete stain and concrete sealant. LastiSeal® Concrete Stain & Sealer combines clear the clear penetrating sealer with UV-resistant pigment stains. Deep-seals and colors the substrate in one simple step. Beats concrete painting and is much safer than acid staining.
Common Use: Porous building materials, concrete floors, patio pavers, concrete driveway, walkways, sidewalks, pool decks, garage floors, properly prepared concrete countertops, statutes, concrete and brick walls.
Product Information – 10-Year Service Life
Your Water-Repellent Barrier for Years To Come! Siloxane/silane based. DryWay penetrates up to 1/2” into concrete and forms an elastomeric water-repellant barrier well below the surface, hidden from UV-rays. Not dependent on cement content. Disappears into concrete and will not change the appearance or friction of your outdoor concrete.
Common Use: Broom finished concrete surfaces, concrete driveways, garage floor, auto body shop, sidewalks, pavers, patios, stucco, blocks.
The Only Sealer Capable of Penetrating Through a Layer of Latex Paint! Polysiloxane-based. Ion-Bond Armor offers a unique subsurface elastomeric sealer that penetrates up to 1-1/2” into concrete. It's like injecting silicone caulk into the pores. Only polysiloxane based concrete sealer that waterproofs against both positive and negative side water pressure. Often applied after RadonSeal for the tightest combined seal against vapor and gases. Seals even through a single layer of latex paint (100% latex.)
Common Use: Often used in combination with RadonSeal® to seal very concrete, cinder blocks, concrete blocks, slump blocks, CMUs, or fiber-reinforced concrete, retaining walls, concrete painted with 1 layer of latex paint, smooth finished surfaces, basement floor, thin concrete, sandstone foundations.
These are not paints or store bought surface coatings but unique, penetrating, long lasting sealers that deep-seal the substrate internally. Our waterproofing sealers are specifically formulated to be the heaviest and strongest concrete sealers in their class. The common features of the RadonSeal line of concrete sealers, brick sealer, and masonry sealants include:
"I want to use RadonSeal but I also want to use LastiSeal Concrete Stain to color my concrete as well. Is this possible?" It is possible to combine RadonSeal with any of the other sealers for the utmost protection of your concrete.
• HOW TO STRENGTHEN CONCRETE & CREATE A SURFACE THAT BEADS WATER?
Combine: RadonSeal & DryWay
Common Use: concrete driveway, garage floor, sidewalk, concrete patio, shop floors
APPLICATION: Seal the concrete with RadonSeal and after 7 days (or later) apply DryWay Water-Repellent Sealer. RadonSeal will work best at strengthening the concrete and sealing against negative and positive side water pressure. DryWay will create that long-lasting water repellent barrier close to the surface (beads surface water.)
• HOW TO SEAL CONCRETE SLABS BEFORE INSTALLING MOISTURE-SENSATIVE FLOORING?
• HOW TO SEAL CONCRETE SLABS AGAINST VAPOR INTRUSION?
Combine: RadonSeal & Ion-Bond Armor
Common Use: slab-on-grade, basement floors, garage floor, factory floors
APPLICATION: Deep-seal the concrete first with RadonSeal and after 10 days (or later) apply Ion-Bond Armor. The combination of RadonSeal and Ion-Bond Armor forms the tightest possible internal seal against water vapor, chemical vapors, and gases, including radon. The surface will remain suitable for paints or adhesives.
• HOW TO STAIN CONCRETE AND SEAL AGAINST RADON TRANSMISSION?
Combine: RadonSeal & LastiSeal Concrete Stain & Sealer
Common Use: basement floors, basement walls, garage floor
APPLICATION: Deep-seal the concrete first with RadonSeal and after 7 days (or later) apply LastiSeal Concrete Stain & Sealer. For this type of application surface porosity is key! Please review the LastiSeal Concrete Stain & Sealer Application, Prep, & Tips webpage for detailed information.
