Good product

Would Not Recommend

Product does what it’s supposed to do I’m guessing. factory rep that I called sold me way too much product and now I can’t return it. They charge 25% restocking fee. This is absurd since I did not need this extra product. Whatever the rep recommends subtract by 50%.

Did not perform as advertised.

Would Not Recommend

Ended up spending a lot money on this product and didn’t perform as advertised at all. The concrete dusting did not improve at all.

This stuff is fantastic

Would Recommend

Put it on my driveway due to spalling that was starting due to the freeze thaw cycle here in Nashville. Since my drive was not in the sunshine it never dried. Put on the densities and then the Sealer. Now the water beads up while the neighbors soaks in. First photo is my driveway, second is mine and the neighbor's. Amazing difference

The weather has been too cold to be able to use this product. Check back in the Spring.

Would Recommend

Please send in the spring . Too cold for the product to be applied.

I used this product last year to treat a 26' X 12' X 6" (thick), 4000 psi concrete patio.

Would Recommend

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?

4500

Would Recommend

Outstanding products. Reta Silver is the best for help. She is spot on for everything you need to know. Talk to her before you start your project or if you have a question.

Didn’t cover as much as expected

Would Recommend

My cement is new. One month old and was absorbing more product than expected. Other than that it went on smoothly

Concrete driveway

Great product went down easily without problems. Use a pump sprayer to put the product down!

Seems to be working

Would Recommend

I don't really know how to tell how a densifier is working. BUT...I will say application was super simple and quick. Over 24 hours before the first rain came and it seems like my driveway is drying faster than my neighbors. The real test will be in 7 days when I apply the 4505 sealer!

First test, epic failure

Would Not Recommend

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.

Performed as Represented.

Would Recommend

As near as my laymens understanding provide, I believe the product worked well. I followed the application instructions explicitly. I have a new garage floor. Protecting it is a priority. While weather is very temperate , it appears to be working as prescribed. Application instructions were solid and worked well. I have topcoated it with 8510 and will be applying a second coat of this product soon. The main test of effectiveness will be winter weather. I am confident we are well-prepared.
