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 to be used on cinderblocks/concrete blocks, not to be used on bricks, use the Siloxa-Tek 8500
  • Online Price includes Paint Care fee in the following states: CA, CO, CT, ME, MN, OR, RI, VT

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 53.
Rated 4 out of 5 by from very capable concrete sealant I have a broken concrete patio that through the years has become very much a moss garden -- especially on the grout between the broken concrete chunks. That made it very difficult to keep clean. I power washed the patio and, once dry, applied this sealant. It does indeed appear to provide a water proof barrier as the water does bead after a rainfall. In another year or so I'll know how good its purported algae/moss growth retardant capabilities work. The sealant was very easy to apply and, just as advertised, it does not discolor the concrete in any way. When dry the concrete looks exactly like it did before the sealant was applied. I'm thus far very pleased with this purchase.

Rated 1 out of 5 by from Stained my driveway This product stained my driveway terribly. I sprayed a light coat over the driveway and gave it a second coat before it dried as the instructions state, but it ended up stained everything. There are brown and greenish blotches scattered randomly throughout. The label says that staining can occur from over application, but I ended up only using half the recommended volume. One and a half gallons did two coats on over 1500 sq ft, so I'm not sure how I could have over applied the product. Some of the drive way turned out fine, but the random blotches make the drive way look terrible. Not worth the cost.

Mixed easily (put a little less than 1 qt in gallon sprayer & diluted with water). Sprayed easily from 1 gal tank sprayer, no back rolling was necessary. When finished, sprayer clean-up with water was simple. Sprayed to wet the concrete and after drying driveway looked the same as untreated... until it rained. On treated it beaded up and untreated absorbed. I guess I will see how it looks in a couple of years, but so far so good. Really, the simplicity over rolling an acrylic is worth the $$ and if it lasts 5 years it will be absolutely better than acrylic which maybe last 2.

Rated 5 out of 5 by from Works as advertised Easy to apply (important to follow instructions and apply 2nd coat right after 1st), water proofing immediately evident and dries clear. Great product!

Rated 4 out of 5 by from So far so good. Let me start out that I have over 3000 sq ft of driveway and patio and I agree with some others, that I had some discoloration (streaking) after applying. But the product clearly states if too much is applied, this can happen. I applied with a sprayer which probably contributed to some over application. I also notice it lightening up after a couple days and a rain. Water rolls right off the drive now and if the product does what it states as far as strengthening - I'll be very pleased!

Rated 4 out of 5 by from Great sealer, tough application. I guess the effort was worth it if the application lasts forever, but I'll have to wait a few years to see. Overall, it was very easy to mix. Glad that it comes in a concentrate. The next morning, it was easy to see that it was sealed well, and even made it obvious that I had missed a small area. I would definitely buy this again. My only complaint was that using a roller allowed the sealant to get dirty, which left some darker areas on my driveway.

Rated 5 out of 5 by from Worked as described. I have a below grade room that was added on to my basement. It has a concrete roof on it that doubles as a porch. For years we have had condensation and leaking issues with that roof. I recently applied the Ghostshield as instructed in two coats. No leaks and no condensation! This stuff works!!

Rated 5 out of 5 by from Definitely works I can't speak to what it does below the surface but as soon as it absorbed and dried the water just beads off the cement...not cheap but worth the price
