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

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.

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).

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 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

The reason I used this product was to eliminate concrete dust that forms over a slab in our crawl space. This product did not address this problem. The concrete was poured 2 years ago and keeps producing powdery dust. The floor seems to be water repellent now but the dust keeps appearing. I guess I will have to try a epoxy coating to seal it.

Rated 5 out of 5 by from This stuff appears to work great! Application with a pump sprayer was super easy. I could tell the product was already doing what it was supposed to on successive passes on my 30x50 slab. I cannot speak to the longevity of the product at this time, but initial results are just as advertised.

Rated 4 out of 5 by from Great stuff Loved this sealer. Very easy to spread its like speeding water and water beads up on the concrete as soon as it is dry to touch The only reason I gave it 4 stars not 5 is because I want to see how it does over winter.

Rated 5 out of 5 by from Great product Worth the price. Easy application if you follow the instructions. Works great. Driveway absolutely repels water.
