Product Details

GHOSTSHIELD SILOXA-TEK 8500 READY TO USE: Versatile, invisible, enduring-the criterion of penetrating concrete sealer. WITHSTANDS THE HARSHEST ELEMENTS: Prevent deicing salt, chloride and freeze-thaw damage with our most recommended sealer. Hydrophobic concrete resists rain, moisture, mold and mildew - preventing cracking. Our proprietary silane/siloxane blend offers longer service life and better performance in a safe water-based formula. PREVENT CRACKING, PITTING & SPALLING: Easily applied with a low-pressure sprayer, roller, or brush on a variety of concrete, brick and masonry applications. Use indoors and outdoors on new and old concrete. Approved by the Department of Transportation for use on highways and bridges, approved by our customers for use on driveways, patios and basements. DRIES INVISIBLE: Imbue your concrete with the power of water and salt repellency while preserving its original appearance. Available ready to use or concentrated (5x). Use stand-alone or as a top-coat with a densifiying primer, such as the Lithi-Tek 4500, for increased performance and abrasion resistance. *Not recommended for colored concrete.
  • Excellent waterproofing - Penetrates deep within the concrete chemically reacting within the pores and capillaries creating a long-lasting hydrophobic surface that beads water
  • 100% breathable - Non-film forming. Allows moisture within the concrete to escape without adverse effects to the sealer. Does not trap moisture
  • Protects against chloride ion penetration - Forms an effective chloride screen dramatically reducing chloride ion ingress preventing deicing salt / chloride damage
  • Reduces moisture intrusion - Resists wind-driven rain, prevents freeze-thaw damage, spalling, pitting and cracking.
  • Resists organic growth - Resists mold, mildew, lichen, and efflorescence
  • Department of Transportation approved - Meets and exceeds DOT specifications
  • Improves durability - Prevents capillary uptake of water and the aggressive substances dissolved in it
  • Resists freeze thaw and thermal cycling damage
  • Natural flat finish - Does not change surface appearance, UV stable will not breakdown with light exposure
  • Can be applied to cured, honed and polished concrete - Ideal for horizontal surfaces exposed to pedestrian and vehicle traffic, compatible with silicate densifiers
  • Water based - Low VOC's, environmentally friendly

    Q:Can I use Lithi-Tek 9500 after I applied already 2 coats of Siloxa-Tek 8500 to stop fine dusting of new poured and polished floor in the garage 4000 mix with fiber. Or what else would you recommend?
    by|Sep 16, 2023
    1 Answer
    Answer This Question

    A:  Thanks for showing an interest in Ghostshield products. Lithi-Tek 9500 will not absorb into a concrete surface treated with Siloxa-Tek 8500. Applying any water-based product to a concrete surface treated with Siloxa-Tek 8500 will result in hydrophobicity (or repellency). To remove Siloxa-Tek 8500, we recommend a light acid etch. Once Siloxa-Tek 8500 is removed, you can apply Lithi-Tek 4500 or Lithi-Tek 9500 to reduce fine dusting.

      Q:I used "Eagle Natural Seal Penetrating Clear Water-Based Concrete and Masonry Water Repellant Sealer and Salt Protectant" two year before on my driveway, can I use this product over it now?
      by|Aug 25, 2023
      1 Answer
      Answer This Question

      A:  Thanks for considering Ghostshield products. Yes; assuming the Eagle product is no longer repelling water / protecting the surface. If the concrete darkens when wet, Siloxa-Tek 8500 should penetrate into the concrete and react to provide a new hydrophobic surface.

        Patio project
        Very pleased from ease of application to the end results in protecting my diy patio project. You can see how well the water beads up after rain.

          Works as advertised
          I needed to seal the cement pad outside my front door as the idiot builder didn't apply waterproofing "before" creating the pad. Instead, they waterproofed "around" the finished pad. Well that doesn't help when the rain pounds water "into" the top of the pad and then into the wall of the basement. Argh! So GhostShield to the rescue.....I apply this about every 2 years to repel the water off the pad. Helps about 95% but rain is very persistent, and it faces the Southern sun.

            EXCELLENT!
            Easy application. 2 coats went on easily. The next day the concrete was showing beads of water on top! The clear natural seal was perfect for our silo, cement base to the barn & the entry steps. Thank you!Highly Recommended :)

              WORKS BETTER THAN ADVERTISED
              AWESOME!! Hard to believe how well this sealed old sand concrete. Water now beads up like a waxed car. I even brush some on a PT swing. Beads up as well.

              Driveway sealing project
              The rating is for ease of use and application. Too soon to rate for endurance and longevity of protection. Product more user friendly than expected. Easy to mix, did not clog the sprayer, rolling was easy. Cleaning the sprayer was quick and easy. Our western Massachusetts weather was the only thing that concerned us. We thought if we applied the sealer end of September we would not have to deal with the heat..that we would have time to work in the coats before it started to dry…but we got rain and wind every other day so we split the project over 2 days that would have sun for a couple days after the application. All went well. We completed the coverage this weekend…today the mailman came to deliver mail and saw all the pearls of water beads on the driveway….he decided to walk on the grass instead…I have no clue what he thought it might be…but we love the dry cement look, the brightness makes the driveway pop!

                Fantastic product! GET THIS!! Long Lasting!!!
                GhostShield does what it claims to do - very well. I purchased GhostShield 8500 for cement, a block brush and sprayer. Look at that shine, water floating on my sidewalk! Mesmerized neighbors will be applying GhostShield in the spring.

                  Water Repelency Works!
                  I used a sprayer to apply it. It was very easy. I was wondering how do I know it is working. Then, after a light rain, attached is what I saw. Water replelency works!

                    Wonderful product
                    I used this on the inside bowl of a large century-old concrete birdbath. There were many fine cracks and three decent cracks. I was concerned about water continuing to get inside the concrete. So I researched online and found Ghostshield 8500. Hadn't heard of it. I let the birdbath dry thoroughly outside in the sun for three days. Follow the directions. Works wonderfully: no change in the color of the concrete and no leakage of water into or through the concrete. Not cheap, but the 16-oz. size was more than enough for this application.

                      While this stuff isn’t cheap, I believe it’s worth protecting your investments. I applied with a pump sprayer to our garden box and as you can see it seems to be working well. No change to the appearance of our blocks. I hope we get 5+ years but time will tell.

                        As Advertised
                        I was skeptical at first, couldnt see how such a product could water proof concrete and be applied so easily. I power washed our 10 year old driveway, let it dry for a few days then applied this product using a pump sprayer in the early morning so that it didnt instantly evaporate giving it a chance to penetrate the concrete. Dont be fooled, pictures of results are attached. Driveway looks great, water just beads, one picture compares my sidewalk to my neighbors un treated driveway.
