Do I really need to epoxy floors and add HVAC unit

There's other types of floor paint.

And there's a spot cooler my apartment uses that might beat the installed split system.
It only requires a 4" flex out the wall for heat rejection.....could get you the brand.

 

Doing anything to the concrete really cuts normal dust and also seals the very corrosive lime that's wearing loose. But a black or grey latex sealer is fine IMO. Epoxy is for color chip speckles and a clear coat! And it's really cool....flat black is $25 a gallon.

Depends on the climate, the a/c but a friend inherited his Dads beautiful Jag and asserts the whole soft rubber and plastic of the car dry rotted in the Houston heat. He leaves the door cracked almost all the dame in the daylight hours, to avoid the heat sink.

Food for thought.

 

Dude congrats on your car...I missed a 6K miles 599GTB and there was none finer, heavily optioned, by a friend.

Time was not right.

I picked up two gallons of floor sealer from a commercial space, a restaurant or gym or something in Austin.
Something a lot less than epoxy.

Yes, when my apartment a/c failed in June, here they came with R2D2 and blew his vent out the kitchen window.
Handled 600 sq. ft. just fine.

 

You got your Ferrari, now you gotta beat the Jones's! j/k, being fellow Georgian, I would definitely suggest doing something to cut down on the humidity. Doesn't have to be anything extravagant, just take a saturday, paint/seal your floors and maybe put a dehumidifier/AC unit in. You didn't mention your size, but all that can be done pretty cheaply. I personally vinyl tiled my floors and piped in HVAC, but if you aren't planning on staying there, might as well just do what's "necessary" for the car.

 

i dont necessarily think the heat is the issue in the garage, the sun through the glass is what warps the dash/leather etc. more important to manage the humidity. adding AC is more $ but obviously you kill 2 birds with one stone.

 

Those single vent portable A/C units are inefficient and don't lower the humidity as much as they should. That's because for all of the extra hot air that it blows out the single vent, it must draw in the corresponding amount of also hot and humid outside air to compensate. Think about it, it can't only pump air out otherwise the air pressure would go down?

I love my mini-split because I work on my own car and that's a lot more pleasant with A/C and heat. But if you do go with the portable type, I highly recommend that you search for a two hose system that brings in outside air in a contained path that blows across the condenser and then vents outside through the second hose.

 

Choose the right floor finish for the substrate and conditions. Latex will likely peel when in contact with tires and will easily chip off if you're working on the car. Even an inexpensive 2K water based garage coating will be more durable and is readily available.

 

I keep my 599 in an offsite storage facility. Unfinished cement floors and no climate control, however I am in Southern California with no real humidity issues. I always keep it covered and on the trickle charger.

 

If your moving in a few years look into something that can be installed now but easily relocated maybe. I have a commercial (but portable) dehumidifier in one part of my basement just in case in the summer.

I’m in Atlanta and opt’d for metallic epoxy and split Mitsubishi unit but no plans on moving any time soon.

You do need to seal the concrete to prevent the previously described problems.
Clear, 100% solids epoxy is very easy to apply and should cost < $1/ sq ft using a roller.

 

We went with a polyurea floor coating as it's more durable and slip resistant, but overkill if you know you will be moving. Costly $$$.

Adding a Mitsubishi mini-split to the garage was one of the best things I've done as now everything in there is protected from the heat, humidity, and salt air we have here. About $2600 for the AC, super efficient and no insulation on block walls. Now I can work on any project or the cars and bikes.

 

We do specify the Mitsubishi split systems, no ide on cost though..keep the lines short.

ttforcefed is a good rec also...

 

I'm in a hot, humid area. Speaking from experience, split system air conditioning systems are great. We have a Daikin in our >600sf garage. It keeps it cool and dry. Well worth the money.

We also had three ss units in an old house that we didn't want to mess up with a.c. ducts. They worked fine.

 

Well there's nothing like an epoxy coated floor if you can afford it. It resists moisture,very easy to maintain (either by hose or sweep and vacuum) and looks awesome.
5$ per sq. ft is about what in costs. make sure your istaller puts a little grit in it to avoid slippinng when wet.

 

No, grit is what will make it look permanently dirty eventually and be abrasive for things you place on the floor. If you go with a system such as the multi-step polyurea with color flake, it has a very high friction coefficient and is not only rated durable enough for a forklift to run on, but slip resistant enough to be used outdoors around water. No grit needed, so it is not abrasive and doesn't catch dirt or grab at things moved across it. Grit works but it's the old solution (from the school of been there, done that)

 

An ac unit will do the same job AND you will be cool. That seems high, IMHO

 

a cheap 24K BTU cool system here runs about 1100 plus install. Mine is going on 3 years old in the garage and works great.

 

My Mitsubishi Mr. Slim split system AC cost just over $2k for a two ton unit installed, and it has a dehumidify setting as well. No reason to throw money away on a dehumidifier alone when an AC does other things and even has a heat cycle if needed.

 

I’m a fan of split systems, having used them for decades in both home and garage. Just choose an installer who has experience with them. You don’t want to be his OJT.
