New concrete slab sealer

[madala]

I have a new 4”slab with fiber reinforcement. I want to treat it in the best way for longevity. I really don’t care about appearance as it’s just a tractor barn. One suggestion i received was to use this product.

Why are you trying to seal it if it's just a tractor barn?

Is there lots of leaks from your tractors? Will the concrete see salt?

Because he wants to seal it.

That product is a densifier. We did a review for it here. It does a good job as a densifier.

Keep in mind that the main job of a densifier is to harden the concrete at the surface - not seal it. Because the actual process of densifying helps to close many of the open pores of the concrete, it does help to reduce ground moisture issues as well as resist moisture at the surface, efflorescence, dusting, and etc. However, it does not actually seal the concrete like a penetrating sealer does.

What do you want a "treatment" to do for you? That is the question.

My only reason for treating it would be to protect my investment by improving longevity. I don’t care about appearance. The floor will not be exposed to salt but I’m sure it will see oil and other fluid spills over time

The densifier will do a good job protecting your concrete from salt damage, but it will provide limited protection against oil and other fluid spills. It really depends on how smooth your surface is. If it's a machine troweled surface, then it will do better.

You may want to consider treating it with GhostShield 8505 or 8510 after the densifier has had a week to react. It will actually seal the concrete and provides oil stain resistance as well. Many on the GJ have done this and are extremely happy. Garage Flooring LLC and ArmorPoxy are both participating vendors here that sell it. This article tells you more about it, but it hasn't been updated with info about the solvent based 8510 (which we would recommend).

If it's more than what you want to spend, then a densifier with a siliconate sealer added would be a good compromise.

Thanks for the responses. I just found out that my contractor used this product immediately after it was poured. https://www.quikrete.com/productlines/concretesealer.asp
Will this preclude using a densifier or other treatment?

That's correct. It will prevent you from applying any product (other than same) to your concrete unless you remove that first. Unfortunately, it's not a very durable product for a busy barn. It will get scratched up and petroleum products will cause it to soften, discolor, and peel over time.

Thx. Sorry to hear that. What would it take to remove it?

You can either use a chemical stripper or grind it off. Chemical strippers are messy and more labor intensive, though grinding can get dusty depending on the type you use. Grinding would be much quicker. The current sealer will most likely protect the concrete for the most part from salts for the winter if you need it to get by for now, but it won't make it through two.

I used a sealer from Euclid Chemicals and would use it again, I think it was Lusterseal 350.

Agree with Shea, Ghostshield which we carry would be a great choice. Use the 4400 Densifier and 8510 Sealer. Great solution especially with a floor with fibers.
