Lithi-Tek LS 9500 is the most advanced, industrial strength, penetrating concrete and masonry waterproofing sealer ever formulated. This unique formula incorporates leading molecular nanotechnology, putting an end to water and moisture migration through any porous cementitious substrate. Lithi-Tek LS 9500 is a uniquely transparent, blended formula with added enzymes and surfactants that aide in accelerating a deeper penetrating disbursement. Thus eliciting a more effective, uniformed chemical reaction between this formula and the concrete / masonry substrate it’s being applied to. Surpassing anything else on the market the Lithi-Tek LS 9500 treats and seals from the inside out; strengthening the concrete as well as providing an oleophobic environment on the surface that will not chip, flake, and delaminate or breakdown with UV light exposure.

  • 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 concrete’s 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, use the Siloxa-Tek 8500
  • Subject to or will include a PaintCare recycling fee in the following states: CA, CT, OR, RI, VT, MN

Rated 4.7 out of 5 by 7 reviewers.
Rated 3 out of 5 by Not worth it for me. This works great if you are looking for a completely transparent non glossy water sealer. It dries completely invisible! It is pretty expensive but it goes a long way. I mixed it with 4 gallons of water as directed and applied it with a roller. It easily covered 1000 Sq. ft. of new concrete. It beads water up like a waxed car which is great. However, it is completely useless for oil stains which is the main reason I bought it. My truck leaks a bit and I didn't want to stain my new driveway. I had some oil spill in the garage that I didn't see for a couple of days and it had soaked through the sealer. I also changed my oil and spilled a little on the floor. It was wiped up in less than 5 minutes and then cleaned with Dawn dish washing soap. Unfortunately, some of the oil soaked through in that short amount of time. August 11, 2014
Rated 5 out of 5 by It actually worked!!! I recently remodeled my basement and prior to sealing the floor with the ghostshield LS 9500 we had minor water spots that would appear from time to time. After a couple of coats the water spots ceased to exist and just to be sure I waited until we had a heavy rain and checked the floor again and to my surprise it was bone dry! Its a great product and my review is 5 stars! May 21, 2014
Rated 5 out of 5 by impressive results The product was easy to apply and dried completely clear. After removing the previous sealer which was also a water based sealer, we applied the Ghostshield Lithi-Tek LS 9500 to our interlocking pavers. We wanted something that left a natural finish without a shine, our last sealer looked good for about 5 months but then started to appear somewhat discolored and irregular. The pro desk at our local Home Depot recommended this product and suggested we give it a try since it seemed to meet our needs. It resist mold and mildew, is not slippery when it gets wet and most importantly it looks natural. Another compelling factor is it is guaranteed to last for up to 100 years and since it is concentrated it actually ended up costing us less then what we had spent on our previous sealer. I've noticed our pavers appear to stay dryer longer and are a lot easier to clean. I really like this product and would recommend it to anyone looking for a natural, easy to use clear sealer for their concrete pavers. June 11, 2014
Rated 5 out of 5 by Perfect for what I needed I bought one gallon of the ghost shield to test it out and will be buying more to complete my project. Though it is a bit pricey it has worked as advertised. The ghost shield is very easy to apply, has no noticeable order and cleans up easily. I will have to differ comment on the 100-year guaranty to a later date though. August 5, 2014
Rated 5 out of 5 by Not cheap but it does the job So far this has worked beautifully. Easy to apply. No clean up problems. Soaks right in and that is the end of the water problems. I put it on a vertical concrete footing that was leaking during heavy rain here in in SW New Mexico (monsoon season). I put it on the inside because the outside was painted. So far everything is bone dry. The mixing ratio of four to one takes the sting out of the price. August 26, 2014
