Product Overview

An industrial-grade, water-based, proprietary sealer designed to densify, strengthen and waterproof concrete: increasing abrasion resistance while reducing moisture and vapor intrusion. Lithi-Tek 9500 is the industries most innovative product. A proprietary blend of chemistries, this clear penetrating sealer not only densifies and hardens concrete making it up to 50% stronger, but its hydrophobic nature resists moisture intrusion and vapor transmission making it the go to choice to seal basements and driveways.

  • Concentrated: 1 gal. makes 5 gal. and covers up to 1000 sq. ft. 2 coats are recommended
  • Resists water and moisture intrusion, becomes an integral part of the concrete, forming a complete body of strength and durability with 100% of the results occurring below the surface, penetrates deeply and seals concretes capillary tracts and shrinkage cracks reducing the growth of mold and mildew and the spread of radon
  • Effectively resists hydrostatic pressure and the spread of vapor transmission, increases concrete's compressive strength, combats Alkali Silica Reaction (ASR), efflorescence attacks are reduced
  • Seals hairline and shrinkage cracks rather than merely masking or bridging them, waterproofing properties remain intact even if the surface is damaged
  • Dries clear, the color and look of the concrete will not change after sealing resulting in 100% transparent surface, easy to apply, labor-cost effective, nontoxic, no VOC's and no harmful fumes
  • Not intended to be used on cinderblocks/concrete blocks or bricks, use the Siloxa-Tek 8500. Not intended to be used on polished concrete or extremely smooth concrete surfaces that have not been acid etched or mechanically scarified. Not intended to be used as a substitution for a concrete vapor barrier or foundation membrane below grade (can be used in conjunction with a concrete membrane).
  • Online Price includes Paint Care fee in the following states: CA, CO, CT, ME, MN, OR, RI, VT

Is this good on 30 yr old concrete

Concrete walk over storage area next to foundation of house. Walk in good condition - surface is weather worn. It sees roof drain-off and 1/2 day sun in Michigan.

Yes, there are no age limitations which effect the performance of the Lithi-Tek LS 9500.

Can you use concrete paint over this?

I want my basement to be waterproof, but would like to have color on the walls and floor for appearance. Thank you, Karen
Asked by: Karen
You can paint on top of the Lithi-Tek LS 9500 as long as you use an oil based or enamel based paint. If not you will need to apply a primer such as zinser or kills prior to using a latex based paint.

I want to use your 9500 product on my new garage. Is there a gloss or semigloss product I can use on top of the 9500 without it needing to be mechanically scarified? Can I use a solvent-based acrylic sealer like Eagle Supreme Seal?
Asked by: JW
As our Lithi-Tek LS 9500 is a highly repellent sealer, you would not be able to apply an acrylic coating over the surface. If you would like to benefit from a concrete densifier while also enjoying the benefits of an acrylic sealer, then we would recommend first priming your concrete with our Lithi-Tek 4500, then follow up with either our Cryli-Tek 5500 (satin finish), or our Cryli-Tek 5505 (gloss finish).

1 gal. Invisible Penetrating Concrete Sealer, Waterproofer Plus Densifier is rated 4.2 out of 5 by 73.

I have a 2-inch reinforced poured concrete garage top that was constructed in 1971. I recently had the top power cleaned and treated with two coats of Ghostshield 9500 in Oct. 2016. What a fantastic product. When it now rains, water beads on my top resembling Saran Wrap just out of the shower. I’m SO GLAD I learned about this product! So penetrating is this product that a pinhole, the size of a pencil point, that I had prior to coating marked on the underside with a pinch of masking table, was observed with the tape itself englazed in the 9500. I’ll definitely be one to recommend this great product! Keep up the great waterproofing products!

There is not much information or reviews out about this product (except the the concrete sealer review site that seems biased. I emailed the maker of Lithi-Tek 9500 to see if this product was appropriate for my basement walls and never heard back so I returned the product to Home Depot. Delivery was free, so no loss. Hey Ghostshield team, can you answer me now? My house was bullt in 1918 and has poured concrete walls which are dusting. They have remnants of old paint on them. I want to finish the basement and will be covering the walls with extruded foam panels before I frame walls and want to harden the walls before I do so. I have taken care of outside moisture issues with downspouts and gutters away from house and grading away from house and walls are a bit damp because it is a basement. Is this the right product or do you recommend the 4500?

Rated 5 out of 5 by from Great stuff Worked just like it said. It has been on for 2 months and the rain just runs off. We are now in snow season. It seems easier to shovel. The snow does not stick as bad. Had some very cold weather and looking at ice on it now. We will see how that comes off this week.

I rolled and brushed brick walls, concrete and stucco walls, and rock sills to strengthen and waterproof: the mortar (1898, limy) and brick in CO, to protect against the AZ environment for another, and just to see what would happen with the deteriorating (acid rain) rock. I didn't spray, as the vertical surfaces would just bounce it back and it was easy to soak the material. I over-used it on the first application and it wouldn't take any more later. It seems to have really done what was expected of it, as my surfaces are tough and deflect water. I'd give a rating (am forced to on form, oh well), but I want to know what the future holds first. Not so good on rock, but it did bind the sand to some extent.

Product applied easily and definitely found the coverage to be exactly what was stated on the packaging. Only average rating because I'm not sure how well it would work on a normal application. I was hoping it would truly not allow water intrusion through the foundation however I have a real issue with my foundation and it probably is just too much for it. It did reduce the amount of moisture penetrating the substrate.

Rated 4 out of 5 by from So far so good So far has worked as advertised. The only issue I have is that it's almost impossible to put 2 coats on. It seems to start working even before I dries so when I rolled over an area I just did a minute ago it wouldn't soak in in most areas. Because of that I send to have missed a few small areas. But now a week later it is working as advertised. Now we'll see how long it lasts.

I have tried many concrete sealers in the past. None can compare to this product. In a word...fantastic. It keeps my basement dry as a bone. We had a rainstorm with over three inches of rain and no seepage what so ever after using your product....kudos...I am so glad I bought it.
