Eco Advance Concrete/Masonry Siloxane Waterproofer is a water-based, low-odor siloxane water repellent that you spray on with a garden sprayer. It is sold ready-to-use by the gallon or as a small concentrate you mix with water, and it is marketed as safe around people, pets and plants. Bottom line: a convenient, breathable, invisible water repellent for patios, walls and pavers, held back by thin published technical data and the need to apply it carefully.

What It Is / How It Works
Eco Advance is its own brand, sold by Eco Advancements Inc., and it is still available in 2026 through hardware and online retailers. You will see several versions of the same concrete/masonry product: a 1-gallon ready-to-use jug (model EACON128PD), a 16 oz concentrate that makes 1 gallon (EACON16CON) and a 64 oz concentrate that makes 5 gallons (EACON64CON). Some stores, such as Do it Best, list it as "Eco Advance Clear Concrete and Masonry Water Repellent Sealer." The brand also makes a separate exterior wood waterproofer, so check the label before you buy.
Our older review lumped it into the "Rainguard family." We could not find any source that confirms Eco Advance is made by Rainguard, so treat them as separate brands. Both use a spray-on, water-based siloxane approach, which is likely where the confusion came from.
A siloxane repellent soaks into the pores of concrete and masonry and leaves them water-repellent from the inside. Rain beads up and runs off instead of soaking in, while water vapor can still pass out of the material. That vapor permeability is the main reason to choose this type over a film-forming acrylic: it does not trap moisture, it does not peel, and the surface looks basically untreated. Eco Advance says the treatment protects against water damage, de-icing salts, oil and stains, mold and mildew, and pool and spa chemicals, and that it does not harm landscape plantings.
Where It Works Best (and where it doesn't)
It suits homeowners who want an easy, low-odor treatment for an exterior concrete patio, a brick porch, stucco or stone veneer, paver walkways or split-face block walls, especially next to gardens or where pets are around. Because it's water-based, you can spray it near plantings with less worry than with solvent-based repellents. The seller also says it can be used in cool weather, down to 34°F, which extends the season compared with many sealers.
It is not the product for a leaking basement wall, a foundation with groundwater pressure or a garage floor where you want gloss and stain protection from a coating. Penetrating repellents slow water absorption; they don't seal cracks or hold back pressurized water. The bigger practical drawback is documentation. We could not find a published technical data sheet with coverage rates, cure time or rain windows, which makes it harder to plan a large job than with brands that publish full specs.
Pros
- Water-based, low odor, non-flammable and low VOC
- Breathable (vapor permeable), so it won't trap moisture or peel
- Dries clear with no sheen
- Quick garden-sprayer application; walkable in under 2 hours
- Concentrate option reduces shipping weight and cost per gallon
- Marketed as safe around people, pets and plants, and usable down to 34°F
Cons
- No published technical data sheet: no official coverage, cure or rain window
- Can pool on stamped or textured concrete if over-applied
- Harder to spray evenly in wind or strong sun, per owner reports
- Some owners needed extra coats before water beaded everywhere
- Won't stop active leaks or hydrostatic pressure
How to Apply It
- Clean the surface. Pressure wash or scrub off dirt, mildew and efflorescence, then let the surface dry thoroughly. Penetrating repellents need open, dry pores to soak in.
- Mix if using concentrate. Follow the label: the 16 oz bottle makes 1 gallon and the 64 oz bottle makes 5 gallons. Don't dilute the ready-to-use jug.
- Pick your weather. Choose a calm day without strong sun beating on the surface, and avoid rain until the treatment has had time to set. The label is the final word on temperatures and timing.
- Spray evenly. Use a pump or garden sprayer with a fan tip, working steadily so the surface is evenly wet. On stamped or textured concrete, dab or back-roll any puddles so they don't dry in place.
- Apply a second coat. Two coats is the common recommendation. Owners note the second coat goes on more easily before the first fully dries; follow the label's timing.
- Check it. After it dries, splash water on a few spots. If any area darkens and soaks it up, give that area another coat. Repeat the splash test every year or so to know when to reapply.
How It Compares
Rainguard Advanced Waterproofer is a similar water-based silane/siloxane spray-on product that publishes a full data sheet: theoretical coverage of about 125–150 sq ft/gal on concrete, a 5–7 day full chemical cure and a 10-year limited warranty. If you want firm numbers to plan with, that transparency is an advantage.
Solvent-based or higher-solids silane/siloxane sealers are a common pick for driveways that see de-icing salt and come in products with fully published specs, though solvent-based versions bring more odor. Our best silane/siloxane concrete sealers covers them.
Acrylic film-forming sealers add color enhancement or a wet look and resist surface stains better, but they sit on top, wear and can peel. Choose those only if you want a visible finish; see best concrete sealers for 2026.
FAQ
Is Eco Advance actually waterproof?
It is a water repellent: it makes concrete and masonry shed rain and absorb much less water. It does not create a membrane, so it won't stop water under pressure or seal cracks.
How long does Eco Advance last?
The brand calls it long-lasting but doesn't publish a service life. Owners commonly report water still beading months to a year or two later. Exposure, traffic and surface porosity all affect how long it lasts, so a yearly splash test is the best guide.
Is Eco Advance made by Rainguard?
We found no source that confirms that. Retail listings name Eco Advance as the brand and Eco Advancements Inc. as the seller. Rainguard is a separate brand with its own siloxane waterproofers.
Can I use it on new concrete?
The seller says it can be used on new concrete and masonry and that it lets them keep curing. Make sure the surface is dry to the touch before spraying.
Verdict
Eco Advance is an easy, friendly-to-use siloxane repellent for homeowners who want an invisible, breathable treatment on patios, brick, stucco and pavers without solvent fumes. Owner feedback on beading and ease of spraying is generally positive. The lack of a published spec sheet, the risk of pooling on textured surfaces and the occasional need for extra coats keep it from scoring higher. It's a fair pick for small to medium DIY jobs; for large or salt-exposed driveways, a better-documented silane/siloxane is the safer choice.
