Rust-Oleum 6500

[Varinn]

Hey guys buying a new house soon the garage is 24x20 (a sizeable upgrade from my current 19'6" x 17'6"). The garage is in good shape for the most part but the floor is ugly and stained bare concrete with a minor slab crack down the middle. It's flat and level and the inspector found nothing foundation wise to be concerned about he just suggested filling the crack and coating it.

I have access to a couple cans of Rust-Oleum "6500 system" in light grey from my dad. Two gallons of the epoxy and two gallons of the activator.

Is it worth using this stuff to coat the floor or should I skip on past it for something else?

I don't care about the glossy clear coats or fancy flakes or anything like that. I just want a fairly durable bright grey to reflect light for working on the cars and the bike.

FYI I'm in Canada so dollar value for purchases is a big consideration

I used the rustoleum solvent based floor coating with clear. 1 coat of each.

Going on 4 years, stuff stands up from welding to brake fluid.

Yes, the Rust-Oleum 6500 100% solids is much better than their EpoxyShield kits. The concrete will require a good acid etch or preferably grinding before you apply it. Pay close attention to the mixing and application instructions, noting to be aware that you only have so much time to apply it.

An epoxy primer is highly recommended but not mandatory. This is what Rust-Oleum recommends.

Noted! Considering I may be lucky enough to save on the material itself there is no harm in putting some of the coin towards renting a grinder and buying some primer.

How many cans of the 6500 would you recommend to cover a 24x20 floor? Are the two gallons I have enough? I just had him send me a couple pictures and it seems like they might not be exactly the same but the part numbers look similar (6582).

Also the last picture isn't great but I took it during our most recent viewing of the house, we haven't taken possession yet. The current owners are obviously not garage people... Can you tell from this picture if a grind alone is what I need or is there other prep that might be necessary so I can plan ahead?

4 gallons of 100% solids epoxy will get you 11-14 mil coverage for 480 sq ft if you prime, which is highly recommended. If you go much thinner than that with 100% solids it will be more difficult to get even coverage. If you dont prime, the epoxy will not penetrate as well and has a good chance of bubbling on you.

The concrete looks pretty dirty, grinding is always recommended over etching. A lot of cleaning to do.

Go with a clear or pigmented poly top coat within your budget

Really appreciate the info! I'm definitely leaning towards renting a machine to do the grind.

According to the docs I see online for this stuff I'll need to purchase another two gallons as it seems each pair (base/activator) adds up to only 1 gallon (0.65g of base and 0.35g of activator in each can)

Just a thought is this epoxy more than one year old or has it beenlaying around? If it’s old, be wary.
