## Description

RadonSeal Standard Deep Penetrating Concrete Sealer (2.5-Gallon) – Basement & Interior/Exterior Concrete Sealer for Water Vapor Resistance, Helps Reduce Moisture Penetration and Seepage - desertcart.com

## Features

- Basement Concrete Sealing – Moisture-Reducing Penetration: Penetrates deep into concrete to fill pores and help reduce water absorption, moisture vapor, and efflorescence buildup. Ideal for basement walls, foundation walls, slabs, crawlspaces, and poured concrete surfaces.
- Concrete Densifier – Strengthens & Hardens Surfaces: Helps harden and strengthen concrete surfaces, reducing dusting, surface wear, cracking, spalling, and damage from salts, de-icing chemicals, freeze-thaw cycles, and abrasion.
- Long-Lasting Penetrating Sealer: Penetrates into concrete to help provide long-term performance. Designed to be a low-maintenance solution that helps resist moisture intrusion and surface deterioration. Helps reduce peeling, flaking, and fading under normal conditions.
- Easy to Apply – Water-Based, Low Odor Formula: Zero VOC formula. Suitable for both interior and exterior concrete surfaces and easy to apply with a standard sprayer or roller.
- Paintable Concrete Sealer – Acts as a Primer for Coatings & Finishes: Prepares concrete surfaces for paints, epoxy coatings, self-leveling products, and flooring systems. Helps improve coating performance by helping reduce moisture, efflorescence, and surface dusting.
- Helps Preserve & Protect Concrete Surfaces: Ideal for poured concrete driveways, patios, sidewalks, pool decks, garage floors, and retaining walls. Helps reduce wear and surface damage caused by weather exposure and daily traffic.
- RadonSeal Standard & Plus: RadonSeal Standard is designed for newer, poured concrete surfaces such as slabs and foundation walls. For older or more porous concrete, including concrete block and cinder block, RadonSeal Plus is recommended for use on those surfaces.

## Questions & Answers

**Q: How is RadonSeal different from coatings or sealers?**
A: Unlike traditional coatings that sit on the surface and can peel or trap moisture, RadonSeal absrobs deep into the concrete and works below the surface. It does not form a film, allowing the concrete to remain breathable.

**Q: Can I apply paint, epoxy, or coatings over RadonSeal?**
A: Yes. When applied to a bare, porous surface, it absorbs into the concrete rather than forming a surface layer, allowing proper adhesion of paints, epoxy, levelers, and coatings.

**Q: What is the coverage rate?**
A: • Poured Concrete: 175–225 sq. ft. per gallon • Concrete Block: 100–125 sq. ft. per gallon As a general guideline, a 1,000 sq. ft. poured concrete surface requires approximately 5 gallons. A 2.5-gallon container will cover about 500 sq. ft.

**Q: Will RadonSeal stop water leaks through cracks?**
A: RadonSeal is not designed to stop active leaks through cracks, joints, or seams. These areas should be repaired using appropriate products such as CrackWeld Floor Crack Repair Kit or RadonSeal DIY Foundation Crack Repair Kit.

**Q: Can RadonSeal be applied to painted or sealed surfaces?**
A: No. RadonSeal must be absorbed through the surface to be effective. It should only be applied to clean, bare, and porous concrete.
