Best Penetrating Concrete Sealer Reviews 2023

Siloxanes, silanes, siliconates, and silicates are all types of penetrating sealers. They are different from other types of sealers because they penetrate into the concrete surface and form a protective barrier. Concrete sealers like epoxy and acrylic are topical in nature and form a protective film or coating on the surface instead of penetrating. Are you looking for the best penetrating concrete sealer? Read this Penetrating concrete sealer review to know more about it.

So, suppose your main aim is to protect your concrete, waterproof it, defy stains, and prevent concrete dusting without worrying about having a gorgeous shiny finish. In that case, the penetrating concrete sealer is for you.

Pick the best penetrating concrete sealer that meets your needs and budget.


Q. Are penetrating concrete sealers slippery?
Ans. The best thing about penetrating sealers over other concrete sealers is that they are not slippery. Other sealers are made up of formulas that make the concrete to be slippery when wet. Penetrating sealers are naturally non-slip.

Q. How long do penetrating sealers last?
Ans. Unlike other sealers on the market, such as decorative concrete sealers, penetrating sealers last long as they don’t fade over time. So, as long as the pavement is protected, you don’t need to apply yearly or so. That’s why you must select a high-quality penetrating sealer, which can last for at least 3 years. Choose one that is made with silane or siloxane. Penetrating sealers with silicate are the weakest, as they don’t offer great water repellency.



  1. Good day, Can you tell me the shelf life of GhostShield siloxa-Tex 8500? I am trying to determine if I can buy the larger size and have it on hand for additional application in say 5 years?
    Thank you

  2. I degreased the garage floor and used HC
    etching solution twice and washed off the garage floor thoroughly.
    Then I applied two coats of HC Heavy Shield Enamel /Stain
    I waited six days before I brought the cars in.
    Still worked great and than it rained and when I brought the cars in the garage under the tires it took the paint off. WHY What can I do now?
