Densifier vs Sealer vs Densifier/Sealer (New Member, Old Question)

[GlennTx]

I’m new to Garage Journal and so far, I feel like a kid in a candy store. There’s so much information and experience represented here. I look forward to being part of the community.

I just purchased a property with a large shop, 5 bays total, 3 of which were recently added on a newly poured foundation in March of this year (03/2019). The shop will be a multifunction workspace primarily used for the following:

• Metal fabrication – Welding, cutting, grinding,…
• Automotive work
• Woodwork

Before I move anything into the shop, I want to either seal or coat the concrete. Originally, I planned to use a 2 part epoxy then after doing some reading, I thought a polyurea would be a better option, but given the fact that I’ll be working with heavy steel, welding and using a cutting torch, I think a densifier/sealer and maybe a stain combination might be the best option for several reasons.

• Durability
• Ease of application
• Ease of maintenance

Here is what I know about the slab:

• Poured in March of 2019.
• Smooth, machine troweled
• No vapor barrier

Given that I’ll be doing everything from welding to auto maintenance and restoration:

1. Should I be considering a combination densifier/sealer like PS104?
2. Should I apply a densifier product like GhostShield Lithi-Tek LS 9500 and call it a day?
3. Should I use a densifier and sealer like GhostShield 4500 densifier Ghostshield 8510?
4. Something else?

I’m not concerned with changing the appearance of the slap. I’m more worried about performance.

Any guidance would be greatly appreciated.

Plans for my personal 'work' garage is to keep is simple with some TL37 lithium densifier and then add some color with SureCrete Eco-Stain before finishing it off with some Ghostshield 8510.
My slab will also be finished off with hard troweling and I was told this will reduce the need for densifier and I could do a 5:1 dilution and probably be fine with two passes.

Ghostshield line of products is worthy of a perusal. Color stain if you want to change the gray look. Vendors here carry it and can help guide you through the process. Use is the defining factor in your choice.

• Automotive work
• Woodwork

Note the 'Protects Against' row

- 9500 is not for oil etc (automotive)

This is why I went w/ the 8510, that and I live in the midwest (winter road salt and meltoff when vehicle parked in garage)

4500 followed by 8510 flood coat is really the way to go. 9500 not so much.

We would recommend the Ghostshield 4500 densifer and 8510 sealer, it should work very well for you.
