Product Overview

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 oleo-phobic environment on the surface that will not chip, flake and delaminate or breakdown with UV light exposure. Do not apply to polished concrete, extremely smooth concrete surfaces, or concrete that has been previously sealed without chemically etching or mechanically scarifying the surface to allow for absorption. Please use caution when applying the Lithi-Tek LS 9500. If this product is applied in excess a surface discoloration may result.

  • 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

Answer: 
Because the concrete is 30+ years old you would be better sealing it in a 2 step process. First apply a stand alone densifier such as the Lithi-Tek 4500 followed by a hydrophobic sealer such as the Siloxa-Tek 8500. It is a 2 step process but the results will be exceptional.

After it has been densified applying the Lithi-Tek LS 9500 will ensure that it is sealed, it will keep water infiltration out, which in return will result in a cleaner looking surface with less opportunity for mold, mildew and organic growth to inhabit it. The only con of the 9500 is it does not protect against deicing salts, chloride ion ingress (salt infiltration) is highly degrading to concrete and over time will break down it's strength and integrity resulting in unsightly spalling and pitting on the surface.

Answer: 
No, the Lithi-Tek LS 9500 works great for poured and cast in place concrete but because it is a hybrid lithium based, penetrating reactive sealer it relies heavily on calcium hydroxide (also known as portlandite) a byproduct of cement hydration in order to produce C-S-H (calcium silicate hydrate) the same binding element that results from adding water to cement in order to be completely effective.

No, the Lithi-Tek LS 9500 works great for poured and cast in place concrete but because it is a hybrid lithium based, penetrating reactive sealer it relies heavily on calcium hydroxide (also known as portlandite) a byproduct of cement hydration in order to produce C-S-H (calcium silicate hydrate) the same binding element that results from adding water to cement in order to be completely effective. Concrete pavers and tiles that are mass produced lack the correct ratio of calcium hydroxide and are exceptionally porous so the better choice for effectively sealing and waterproofing these substrates are a high solids silane/siloxane such as the Siloxa-Tek 8500 or Siloxa-Tek 8505. Both of these options are penetrating and will render the concrete waterproof since silanes and siloxanes are very hydrophobic but neither rely on calcium hydroxide being present in order to be effective. The result is a better hydrophobic surface environment and a drier balcony. Read Less

Answer: 
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.

Apply two coats wet on wet or about 10 minutes in-between coats. don't let the first coat dry before you apply the second coat.

The sealer dries clear but if over applied you may end up with a blotchy appearance, this does not effect the sealers performance however if applied uneven it is not as aesthetically pleasing.

Rated 4.2 out of 5 by 39 reviewers.
Rated 1.0 out of 5.0 by 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. October 2, 2016
Rated 5.0 out of 5.0 by Works Very Well Product mixed easily. I applied it with a cheap tank sprayer. Went on well and very quickly. I did about 1,000 SQ FT. It has it's chemical effect very quickly. I noticed where I had some overspray the second coat would already not soak into the surface. I observed the water resistant effect the first time it rained. Water simply beads up. It will not soak in. I applied the product to the sidewalk in front of my house, but only to my property line. I cut off the application at a joint in the cement. I have attached a picture of the area where my application ended after having thrown a bucket of water on it. It's easy to see on the bottom, light color cement because of no penetration, on the top, dark color because the water soaks into the untreated cement. These results sell everyone who looks at it on the product. I have sealed concreate driveways since 2005 and this is the best results I have ever seen. And the price is less than the sealer the cement contractor wanted to sell me. (Diamond coat or something like that) If this product lasts like promised it will put all other similar products out of business. I applied this at the end of June, 2016. August 10, 2016
Rated 4.0 out of 5.0 by 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. August 30, 2016
Rated 5.0 out of 5.0 by 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! October 26, 2016
Rated 4.0 out of 5.0 by 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. October 18, 2016
Rated 3.0 out of 5.0 by Returned this for the 8500 Version After purchasing this product, reading reviews and going to the mfg website - I decided to get the 8500 instead. Note that you do not dilute the 8500 and is therefore more expensive to apply. Here are some of the things I found on Ghostshield products: Lithi-Tek LS 9500 is a simple and effective way to densify and waterproof interior or exterior concrete. Extremely popular for driveways and sidewalks as well as garages and basements when oil stains are not a primary concern. For best results, two coats are suggested. If Oil Stains are a primary concern the Ghostshield 8505 is a better choice. Ghostshield 8500 may be a better choice for customers in a Freeze Thaw area with no concerns of oil stains. QUESTION: Can this product be applied over another product? - There appears to be a primer on the concrete already. Does the primer need to be removed before applying this product or will it work 100% over the top of the primer? ANSWER You need to remove the primer before applying the Lithi-Tek LS 9500. The concrete needs to be clean and un-sealed/un-primed in order for the product to effectively penetrate and react. . October 18, 2016
Rated 5.0 out of 5.0 by Concrete sealer Easily applied with sprayer. Low odor, and covered concrete with one application. Results were excellent September 27, 2016
Rated 5.0 out of 5.0 by Works as expected. The Invisible Penetrating Concrete Sealer repels salty water (sodium chloride) really well. My garage walls were falling apart in several areas. I removed all the excess concrete that was loose and repaired the affected areas. I applied the Invisible Penetrating Concrete Sealer on the repaired area last year. I was surprised to how well it was repelling the salt water over the winter. Previously, I would have noticed the crumbling of loose concrete but there nothing after the application. I bought some more to protect the remainder of the walls and the floor. September 3, 2016
