I built a new shop 2 years ago for working on equipment and wanted to put something on the floor to protect it but didn't want an epoxy coating or something shiny and slippery.
So after much research I found this product ULTRASIL LI+ it seals, densifies and dustproofs concrete in one operation and is made by Euclid Chemical.
I purchased it through my local concrete company in 5 gal buckets and applied it to my floor by using a paint roller. I think it took 10+ gallons to do a 40' X 50' floor.
Best decision I ever made to use this product, the concrete looks the same after applying, spills wipe up easy, its not slippery when wet, won't burn if welding or cutting and it eliminates the dust from the concrete when sweeping the floor.
Be aware if you do use this product that when you apply it to the concrete the concrete will turn dirt brown while it is working into the floor but IT THE CONCRETE DOES RETURN TO IT'S NORMAL COLOR.
This reaction really freaked me out when it happened.
Here is the link to their website.
