Read MoreConcrete Waterproofing and Radon Mitigation in One Sealer
The Permanent Concrete Sealing Solution – Concrete paints, waterproofing sealers, or cementitious coatings are a temporary fix only. They crack or peel and cannot stop gases or water vapor. Why not tackle the root cause of the problem? Seal those pesky pores inside concrete with RadonSeal and combine waterproofing, damp-proofing, mold remediation, and radon mitigation in one!
RadonSeal is Your Damp Proofing Solution!
Backed by a Lifetime Warranty – RadonSeal offers much more for your concrete than do common surface sealants that can be found in major hardware stores. RadonSeal is a permanent concrete sealer so you will never need to apply the product again! This water-based, clear, penetrating sealer will not leave a film or color on your concrete. RadonSeal works by sealing porous cementitious materials – indoor and outdoor, new and old; concrete, concrete blocks, cinder blocks, mortar, and stucco. Backed by a Limited Lifetime Warranty.
Safe Spray-On or Roll-On Application – Apply RadonSeal to your basement concrete using an airless sprayer, hand-pump "garden" sprayer, roller, or brush. RadonSeal is a waterborne concrete sealer – ZERO VOCs, no noxious fumes, non-toxic, non-flammable, and non-hazardous. The sealer absorbs inside the concrete leaving the surface slip-resistant and paintable (does not change the appearance or profile of the concrete).
RadonSeal® Penetrating Concrete Sealer is a deep-penetrating reactive concrete sealer that penetrates deep into concrete (up to 4"), reacts with lime and alkalis, forcefully expands inside capillaries, and hardens as an insoluble silicate mineral. (Silicates are the "binders" in concrete.)
The many benefits of sealing your concrete with RadonSeal® Penetrating Concrete Sealer:
- Seals concrete against water seepage, water vapor.
- Reduces indoor humidity preventing the growth of molds and mildew, alleviates basement odors.
- Helps prevent the growth of molds, mildew, and musty odors.
- Strengthens concrete reducing concrete dusting, spalling, and cracking.
- Seals against efflorescence.
- Neutralizes alkalis, protects paints, thinset, epoxy coatings, etc. Acts as a concrete primer by opening the surface pores.
