2024 Surebond SB-4000 Sealer Review

If you have questions or have used the Surebond SB-4000 Sealer product, please ask me in our Q&A area below. We are here to help!

I have found that the SB-4000 Water Repelling Invisible Sealer is a water-based, penetrating, low VOC sealer that provides an invisible, durable barrier against liquid absorption on retaining walls, concrete, and pavers. The finish has a natural look that does not affect the appearance of the substrate.

Concrete Sealer Ingredients: Blend of  Siloxanes

Concrete Sealer Type: Penetrating Clear Sealer

SB-4000 Concrete Sealer Scores (1-10)

Ease of Application: 10

– The SB-4000 is very easy to apply and dries within an hour. I used a Chapin concrete sealer sprayer and applied 5 gallons of the sealer to 750 sq. feet in under 20 minutes.

Water Repellency: 9

Surebond SB-4000 has excellent water repellency for the brick blocks. Water beaded up, and there was very little penetration, even with a heavy flow of water on the surface.

Cost per foot: 7

The Surebond SB-4000 is one of the more expensive sealers on the market. It does offer very good results, though. My cost to apply it was about $.25 a sq. foot, almost double that of other brands.

Durability/Spalling After 2 Years: 8

After two years, the Surebond 4000 still beaded up water, and there were no visible hairline cracks or pitting on the blocks. Conditions were virtually the same but with a small amount of mold and green algae.

Warranty: 6

The manufacturer is very vague on the warranty and has no actual dates.

My Overall Score SB-4000 Concrete Sealer: 8

The SB-4000 would have been rated higher without the warranty. We like concrete sealer warranties that protect for 5, 6, or more years. Besides the warranty, the SB-4000 is an excellent and capable concrete sealer and water repellent.

*The application is excellent, works well, and repels water, but the warranty is vague.
