What Customers Are Saying
The concrete densifier appears to be generally effective at hardening surfaces and reducing dusting, with many users reporting easy application and successful results on various concrete surfaces. However, some experienced issues with residue or the product not fully addressing moisture and water absorption. While it can improve durability and appearance, customers may need to use additional sealers or treatments to fully address certain concerns.

I put the stuff over the concrete hardener. It went on pretty easy. I just had to continually broom it out to keep from puddling. We have not had any rain here yet since I applied it, so I will have to edit my review to see how it works in action.

Very easy to apply.
We built a new home and decided to have concrete floors inside our home. After we had polished the floors, we were looking for something to give it final treatment and trying to achieve a little bit darker color. This product worked excellent. We did not want our floors super shinny and this product gave them the perfect look.

Does the job
Easy to work with and leaves a nice gloss shield I wasn’t expecting. Wish I would have stoped here. Unfortunately, I topped this 7 days later with 8500 and regret it. Left a ghastly white coating on top of the densifier finish in a new concrete shower pan.

Keep your expectations low...
Could have just sprayed water for a similar effect. Followed the directions exactly as stated by the manufacturer. Stuff looked great going on, then dried to a normal white/grey concrete color. Waited a couple days before going into the shop. Pulled a tractor in with the a/c on and dripping condensation. Well, the water absorbed into the concrete like it had never had the densifier applied. Then the tractor dripped some oil, that oil soaked in also. Next, I drove another tractor into the shop an...

Is it working?
I have no idea how to tell if this is actually working. I'm just going to assume it is. I got it because I was told it would make the sealer work better. Hopefully it does. Overall, it was easy to use and dried nice and clear as advertised. If you get any puddles it will leave a white salty looking crust on top of the concrete that doesn't come off easily. I was really worried about messing up and having that happen everywhere, but it turned out okay. We did get a little bit of it right along a ...

Highly recommended
Worked great to seal a concrete garage floor that was creating dust. Easy to apply and one concentrated gallon covered my two car garage floor. Highly recommended.
From Ghostshield Concrete Sealers
Applied easily
Applied easily, dried clear, except where I overapplied it. It turned slightly white and was a pain to remove.

Read the instructions and mix with water!
Don’t make my mistake and apply it directly from the container it needs to be mixed with four gallons of water. It was a nightmare removing it from the concrete undiluted.

Less of a musty smell
I purchased this to seal the walls and floors of my basement before I painted it. The basement definitely has less of the musty basement smell.
