Silane/Siloxane Sealer Foundation Armor Sx5000 Reviews

Applicable to the interior and exterior surfaces

First and foremost, this is an excellent sealer as it can be applied either inside or outside. So, regardless of where the surface is located, you will still be able to protect it using the same product instead of buying another one. It can also be applied horizontally or vertically.

Creates a barrier that prevents damage

After sealing your surface using the Armor SX5000 WB, it will repel water and other stains. This water-based sealer penetrates deep into the surface, where it chemically reacts to create water-repellent barriers within the pores, which reduces water absorption by up to 95%. In return, it will resist damage caused by water absorption like spalling, cracking, salt damage, pitting, freeze-thaw damage, efflorescence, and mold & mildew. This is one of the reasons it was approved by the Department of Transportation (DOT) as being a water-repellent sealer.

Easy to apply

Using this sealer doesn’t require one to be a professional, as it is easy and fast. Simply get a brush, roller, or pump sprayer. A brush is suitable to use when you have a small surface to cover, while a pump sprayer is ideal for covering a larger area.

Extremely durable

A challenge that many homeowners face is acquiring a sealer that doesn’t last for long. Most silane sealers last up to 5 years. But this is not the case with Armor SX5000, as it can last up to 10 years. As a result, you can rest assured that your pavement or driveway is protected away from the elements for at least the next 8 years or so.

Covers a wider area

The 5 gallons Foundation Armor SX5000 WB sealer can cover up to 1000 square feet in just 1 coat and up to 500 square feet in two coats. This is amazing, as most sealers are not able to cover such a wide area. If you’re covering a small area, you can always keep the remaining sealer for future use.

Question: Do I have to stir the Sx5000 sealer before using it?
Answer: Yes, you should. It is not a must to stir this sealant before using it, as some clients say they used it directly without stirring. At times, good stuff may sit at the bottom of the can, and stirring or shaking it will ensure that the sealer is properly mixed and not lacking anything.

Question: Is the Foundation Armor Sx5000 capable of protecting my driveway from oil and transmission stains?
Answer: Yes, it is. This sealer has silane/siloxane, which is outstanding when it comes to penetrating and sealing a surface. Rainwater, oil, and other stains will not penetrate into the surface but instead, bead or pond on it.

Question: Can you get a glossy, wet look?
Answer: No, it won’t change the look. For a wet look, you can try Armor WL550 or AR350.

Question: Can you coat it on a damp or wet driveway?
Answer: As it is an oil-based sealant, it is water-repellent. So you can’t apply it to a wet surface. You must dry the surface before application.

Question: Does Armor SX5000 have an odor?
Answer: Yes, but Armor SX5000 WB (water-based) sealant is odorless.

Question: How long do you have to cure the concrete before coating it?
Answer: A minimum of 28 days is recommended.

Question: How long does the coating last?
Answer: Depending on the surface, the brand provides a 7–10 years warranty. So it may last at least 8 years.

Question: Can you use it on an asphalt driveway?
Answer: No, only for concrete driveways.

  2. I want to use Armor sx 5000 on my concrete floor in my house. l like that it lasts 7-10 years and it didn’t change the color of the concrete.
    1. Is Armor as 5000 WB just as good?
    2. Can I use a polyurethane or something similar to get a satin finish with out changing the color? (I don’t want a wet look)
    thanks deb o.

  3. we bought an outdoor concrete water fountain and recently etched and restained the fountain with Behr semi transparent concrete decorative stain. we bought the sx5000 to protect the concrete and stain finish from water that will be constant. will this product work on stained concrete?

  4. The question wasn’t answered as to whether the solvent based and water based products are equally good. Are they meant for different applications? Which is better for my flagstone pool deck and walkways?

    • Water-based sealers are easy to clean, provide a matte finish, have a mild odor, and have low VOC.
      Solvent-based sealers are more complex to clean, provide a wet look finish, have a strong odor, and have high VOC.

      If you previously sealed your pavers, can you apply a new sealer on top of what’s already there? Well, first, you need to know what type of sealer was originally used.
      If a solvent-based sealer was originally used, you would want to reseal using a solvent-based sealer.
      If it was a water-based sealer, you could safely reseal using either a solvent-based or water-based sealer.

      A water-based sealer cannot be applied on top of a solvent-based sealer.

  5. I bought a 5 gallon container of SX5000 in 2015 but never used it. Is it ok to use now or is the product now too old to be effective?

  6. Application info says 1 coat required; 2 suggested. Will 1 coat offer the protection of 7-10 years as indicated on Foundation Armor website? Have total of about 2,600 sq ft. of exposed aggregate to seal. Two coats would be very expensive as well as the time it would take. Could I spray the sealer then use a roller to cross roll and spread to insure full coverage?
