We appreciate your questions and your interest! Q: Can this be used on concrete walls in a basement that is mostly used for storage? A: Yes, absolutely. RadonSeal is widely used both commercially and residentially on indoor and outdoor concrete surfaces, including walls and floors. Applications include basements, crawl spaces, slab-on-grade foundations, garage floors, patios, pool decks, storage areas, warehouses, parking lots, sidewalks, cart paths, retaining walls, and similar areas. Q: Can it be applied with a paint brush or roller? A: RadonSeal is a penetrating sealer, and we highly recommend applying it with a standard handheld, low-pressure plastic pump sprayer for best results. If you’re interested in discussing your project further, please feel free to reach out to us directly, and one of our experts will be happy to assist with any questions you may have. Kind Regards, ----------------- Patrick Product Expert RadonSeal

Thank you for your question and interest! RadonSeal Penetrating Concrete Sealer is designed for use on bare and porous surfaces such as concrete, concrete blocks, cinder blocks, bare limestone, and bare stucco. However, it is not suitable for slate tiles, as slate is naturally dense and has low porosity, making it resistant to both water absorption and penetrating sealers. The most effective way to prevent moisture intrusion is to first seal the concrete floor with RadonSeal. Once sealed, you can then install tiles, paints, epoxies, coatings, or similar materials over the treated concrete surface. KInd Regards, ----------------- Patrick Product Expert RadonSeal

Yes, it will work fine, follow the directions for application. Mike

Thank you for your question, and we appreciate your interest! RadonSeal Penetrating Concrete Sealer is commonly used prior to, and in conjunction with, the application of bituminous foundation coatings and dimpled membrane systems, which are often required to meet building code standards. RadonSeal is a penetrating, breathable sealer. As penetrating sealers are not classified as surface coatings, they are not intended to function as a standalone waterproofing barrier for below-grade foundation walls. On their own, they do not seal cracks, joints, seams, or other structural openings through which water may easily infiltrate. After applying RadonSeal to the concrete, you can safely proceed with virtually any additional surface treatment, as it will not inhibit the bond of coatings, paints, epoxy, adhesives, self-leveling compounds, and similar materials. The more steps you take to block water intrusion, the drier and more protected your home will be. Kind Regards, ----------------- Customer Support RadonSeal

Rinsing the floor after application of RadonSeal is precautionary. It helps to move over-applied sealer into the pores, preventing it from drying on the surface. This is especially important on tight, or smooth troweled floors, or when too much sealer is applied. Sealer that dries on the surface may interfere with adhesives, paints, or flooring. If the floor is properly prepped and the sealer is absorbed, then this step is not needed. I hope that helps. As always, if you want to talk about your project in detail, give us a call.

Thank you for your interest in our product! To answer your question directly, yes, RadonSeal Standard can be applied to both new and old concrete. For context, RadonSeal comes in two versions: Standard and Plus, both of which are suitable for new or old concrete. However, we recommend using RadonSeal Plus, the higher-concentrated version, for poured concrete older than 20 years and for concrete blocks, as they typically contain less Portland cement. For poured concrete under 20 years old, RadonSeal Standard is the preferred option. Regards, ------------ Customer Support RadonSeal

Deep sealing your slab with RadonSeal before installing floor is a smart decision to protect the flooring from water damage and prevent development of mold or efflorescence beneath the floor.

Considering it has been previously sealed with RadonSeal, we would recommend using our LastiSeal Brick & Concrete Sealer.
