What Customers Are Saying

The product is easy to apply and dries quickly to a clear, natural finish that does not change the concrete's appearance. It effectively repels water, protecting the concrete from damage, and the water beading lasts for years. The sealer is durable and long-lasting, with claims of up to 10 years of protection, though it is more expensive than some alternatives. Overall, the product is highly recommended for its quality and performance.

20 Year old Basement floor is finally dry and right, Even after a water leak!!

Would Recommend

The concrete contractor who built my 2000 sq.ft. basement failed to install proper drainage and lay heavy mil plastic sheeting under the floor. For 20 years I had to run 2 Dehumidifiers to prevent a musty smell in the basement. I had tried to seal the floor with epoxy paint with poor results. After the original house burned, I had a sand blasting company remove all previous floor coatings when they blasted the basement walls to remove the smoke & soot. I did extensive online research and re...

Ghostshield rocks

Would Recommend

Sprayed my driveway to protect it from the elements and salt. Sprayed two coats. Water beads up on my driveway and looks like marbles. I'd say it's working as advertised. Second time using the 8500 product. Love it and would highly recommend.

Needed more!

Would Recommend

This stuff is phenomenal! I purchased it a year ago to do a particularly wet area of stone on the exterior of our home. Still beading and protecting this year. I decided to do additional areas around the house that tend to see more direct weather just to insure dryness behind the stone. Love this product! Thanks GHOSTSHIELD!!

Worked as advertised

Would Recommend

Use this product to seal my driveway and concrete stamped patio. Since it was water based, it was easily spread using my hand pump sprayer and was very easy to clean up (clean up sprayer). A few days later it rained and the sealant worked as advertised as I saw the rain bead up on the patio and driveway. It dried clear so no discoloration took place. Great product if not a bit pricy. But well worth it.

Seems to work very well

Would Recommend

Put two coats on with garden sprayer. Did a water test next day and water beads up great. Time will tell how long it lasts.

Great sealant

Would Recommend

Pressure-washed concrete walkway and driveway prior to treating with Ghostshield. Water now beads up on all treated surfaces. Used product before, and while beading fades after a while (months to year), concrete still seems protected, as it remains cleaner and whiter than untreated sections after 2 years

Excellent product just pricey

Would Recommend

I applied the Ghost shield 8500 on my brand new concrete pool deck (poured 4 months ago) over the weekend using a sprayer and doing 2 coats. The results are like nothing I've ever seen before. Water runs off as if there is a Teflon coating yet the surface stays rough and non slippery. The pool guys that winterized my pool yesterday were blown away. They took pictures of the bottle and will start to offer it as a sealer. I hope the sealer lasts a few years since it was expensive.

Applied with low volume sprayer. Alowed a second coat almost immediately.

Easy to apply and clean up. Left our pavers their natural color. Water beads up and dries quickly.

Great Product

Would Recommend

Ghostshield is one of only 3 companies that I would consider using for sealing concrete. Siloxa-Tek 8500 is a terrific, high quality sealer that I've used for nearly 3 years in sealing many driveways, sidewalks, curbs, and brick mailboxes in my HOA. It's made our neighborhood look much better than it has ever looked. After 2.5 years since pressure washing and sealing the first of many driveways and sidewalks, they still look as good as new.

Thank you! It works!

Would Recommend

This product definitely did the job for the project I needed it for! I was sealing a bird bath that had multiple staining throughout the bath. It was constantly discolored and looking rusty. So I wondered what I could do. Upon using this product I now see a clean water bath, sealed and refreshed! Thank you!

I was looking to seal my stone bird bath's cracks and this product helped to change my bird bath from horribly discolored to clean & clear! Thank you!

Easy application

Would Recommend

Easy to apply with a pump sprayer. 2 gallons covered our chimney in 3 fine passes. Application was 10 days ago (early September) so I can't yet comment on the effectiveness or longevity of the product.

Very satisfied

Would Recommend

Applied this three years ago and I have been very satisfied with the protection. I just re-applied it to my driveway because I live in Wisconsin and use a lot of rock salt on my driveway in the winter. I wanted to make sure the driveway remains protected before I actually see signs of wear.

Great Product! Recommendation from contractor.

Easy to apply. Have to wait to see how well it works this winter

Great product and easy to apply.

Would Recommend

After pressure washing my front walkway and allowing 24 hours to dry, I used a 1/2 inch nap roller to apply the sealer. I was careful to brush the edges and spread out and puddles of sealer in anywhere it settled in the texture of the stamped concrete. I was careful to apply the second coat of sealer before the first coat completely dried. Water now beads up. You can see that even morning dew now beads up. One or the reasons I chose this product is it provides protection against salt damage on c...

Good job repelling water, not oil and grease

Would Recommend

Product does a good job of repelling water, but oil and grease can still stain the concrete. Guess I should have used the Siloxa-Tek 8510 instead.
