How To Select A Concrete Sealer
Selecting a concrete sealer should not be rocket science. That is why we developed the flow chart above. There are several key questions to ask: Will your concrete be exposed to freezing temperatures and road salts? If so and you do not want a gloss, then the question becomes do you want protection from Oil. In most cases that means Ghost Shield LS4500 and 8510 are going to be the best choice.
If you do want gloss and it is for exterior applications, a coat or two of clear polyurea is an outstanding choice.
In warm weather climates, where no exposure to freezing temperatures or oil and no need for gloss, LS9500 is an ok less expensive choice. It does not provide anywhere near the protection provided by Ghostshield 8510.
