Beware Bait 'n Switch
Beware that this "concentrate" gallon USED TO make 4 gallons for priming. Has now been cut in half for the same price. (See photo) - There's no reason to waste money on this densifier when other Ghostshield products (with densifier) still maintain the "claim-to-fame" 1:4 ratios. Caveat emptor, wasted $$$ now that my driveway is only half-covered.

First test, epic failure
I applied both the 8510 and the 4500, per Ghost Shield’s recommendation to prevent oil stains if dripped from a parked car or truck. The first contractor truck that had a little drip was on my concrete today and the results are not even close to worth the money I spent. The spots were discovered and cleaned within hours of happening and it’s as if there was nothing ever put on the concrete. I’ll let the photos speak for themselves.

I would highly recommend this product. It was easy to apply. Be very careful not to over apply product due to it will leave a white residue. This happened to me on my driveway. But I am still pleased with the product and know it will seal my concrete for a long time.

Ghostshield
The Ghostshield concentrated was very easy to apply. However, I did not clean up the excess in time and this caused some white residue on my driveway. However, I am pleased with this product. I am confident that it will seal my concrete for years.

Use with 9500
I wanted to get the absolute best results so I contacted Ghostshield and told them my situation. They recommended 4500 followed by the 8500 for my badly worn 98 year old concrete. I had already purchased the 9500 and had it laying around and they said it would work as a substitute for the 8500.
After cleaning, acid etching, and neutralizing and letting the concrete dry I applied the 4500. Apply it thinly or it may show white residue. The residue can be scrubbed off. I let the 4500 cure for 7 days then I applied the 9500--2 coats.
I had significant efflorescence, dusting, etc prior to sealing with this two coat process. I can tell you the efflorescence has been reduced significantly and water beads right off. Hope this helps someone trying to find their way in the crowded world of concrete sealers.

I used this product last year to treat a 26' X 12' X 6" (thick), 4000 psi concrete patio.
Now I want to use an epoxy topcoat. Will the epoxy coating adhere to the Lithi-Tek 4500 treated concrete or will I have to have it ground off?

Didn’t cover as much as expected
My cement is new. One month old and was absorbing more product than expected. Other than that it went on smoothly

Approx. coverage per 2.5 Gal. pail: Bricks - 400 sq. ft. to 500 sq. ft., Poured Concrete - 500 to 600 sq. ft. More porous surfaces may require a light second application.
