Ideal for indoor and outdoor use on basement floors, foundation walls, and slabs, it strengthens concrete against environmental damage while remaining clear, paintable, and non-slip.

## Description

## Features

- Penetrates Concrete (up to 4") – Seals the internal matrix of concrete, by blocking pores and capillaries, reducing negative-side water seepage, moisture, water vapor, and radon gas. Ideal for basement floors, foundation walls, slab-on-grade, and both indoor and outdoor poured concrete slabs and walls.
- Hardens & Strengthens Concrete – RadonSeal Plus reinforces concrete surfaces to minimize dusting, efflorescence, and damage from road salts, de-icing chemicals, and freeze-thaw cycles.
- Easy-to-Apply Formula – Water-based. Zero VOCs. No special tools needed. Simply apply with a standard handheld, pump-up, low-pressure sprayer. A roller can also be used when spraying is not practical.
- Permanent – Bonds deep within the concrete, becoming an integral part of the structure. Resistant to hydrostatic water pressure, it does not form a surface film and will not peel, fade, or yellow.
- Non-Slip – RadonSeal Plus absorbs deep into concrete to seal from within without altering the surface appearance or slip coefficient.
- Paintable & Protective – Applied before coatings, RadonSeal prepares and seals concrete surfaces while protecting them. Ideal for use prior to concrete paints, epoxy coatings, clear coatings, overlays, or adhesives.
- Does Not Trap Moisture – Unlike traditional concrete sealers, RadonSeal Plus seals concrete internally without trapping moisture at the surface, allowing the concrete to dry naturally.

## Questions & Answers

**Q: can this be used on concrete roofs where the rain water is channeled to a storage cistern for drinking water?**
A: Yes, RadonSeal can be used for this application. No problem. There is no concern about leaching or water contamination.

**Q: How well does this work for seepage between the floor and foundation wall?**
A: Very well. Used it once on walls and floor never saw any wetness after that?

**Q: Can this be used over painted basement walls**
A: RadonSeal is a penetrating sealer. This type of product can only be applied to bare & porous surfaces. All paints, previously applied sealers, and other materials that may prevent sealer penetration should be completely removed before treatment.

**Q: Can this product eat away at a basement concrete floor causing solf spots, chipping and cracking. is it possible if over used that it may destroy the**
A: Not at all. My floor and walls are stronger then ever. It purges out dirt and loose dust when first applied but stengthens the concrete after it cures.I think the curing process takes a couple of days to a week. I just swept and washed the dirt away
