Sealing Concrete?

[Mac5005]

Curious about options for sealing a concrete slab,

That doesn’t have a vapor barrier under it.

I’m certain there is no vapor barrier under the slabs that my shop is on.

Doesn’t matter on the side that is 50x 75.

But the other side that is 32x48, that I have 4ton HVAC in , and I do most of my fab work, I notice whenever I move a rubber mat, it is wet underneath.

I understand most options are only for slabs with a vapor barrier underneath, as the upward moisture drive will cause adhesion issues with epoxy etc.

Are there any options out there to seal the concrete when there isn’t a vapor barrier.

Reason for sealing is to make it easier to sweep/clean up without just creating more dust and grit coming off the slab itself.

Thanks in advance.

When you apply a densifier to raw concrete it seeps into all of the pores and the capillary voids creating a harder,...
