I strongly recommend you upgrade to 400 amp service for your home, then have your electrician run whatever sub-panels you need from that. With two HVACs and the toys you mentioned, you will max out your 200 amp service every time the AC kicks on. Don't ask me how I know.

It cost me ~$700 to do my 25'x25' garage. The only thing I would do different would be to sandblast instead of wasting time with the acid etch stuff. I've got a few bubbles and talking to some cement guys, sandblasting it gives it about a perfect texture for paint.

I also would just count on doing two coats. I did two coats, but there is chips inbetween the coats, then a clear top coat. Looks awesome though. Had my garage been 30X30 it would've cost the same as I had to throw out alot of paint.

when I moved into my house, I did the garage floor epoxy/paint myself. Was about $150 and came out really nicely. Make sure you use the cement etching solution first though!

If you do it yourself wear a respirator. Otherwise you might lose a lung.

Sheeewwwwweee...400Amps? Good lord. The power company is doing a calculation on it to see if the 200 I have is adequate but I hope I gave them all the right information. The heatpumps I'm using will be split ductless systems with 18seer efficiency and they're only drawing around 15amps (each) with both the indoor and outdoor units (230v).

I have a friend in the flooring business so the epoxy will come once the slab has matured. Good tip on the sandblasting - I have a large pot blaster so that should go pretty quickly....but good lord - the cleanup after sandblasting 864 sq feet of concrete would be a nightmare!

Nah. Vacuum most of it up and re-use it over and over. Hose and a squeegee for the really fine stuff.

Here's mine all done. Definetly get the "Proffessional" kits, and do a clear over the top.

May be close, but my bet is the 200 will do by the looks and size of the house in the photos and drawing. (JW you must live in WAY bigger abodes than me and Jake ) Again, you haven't described anything too extravagant, and Heat pumps are a good/highly efficient move.

Nice floor Karl

The 400 service delivers 320 continuous. The AC loads up a lot when it comes on, and you said there were two. I read welder and some other non-hobyist-type tools in the shop. Add the tech from the graphics business (computers, monitors, printers, plotters)...

Don't take my word for it - most power companies offer 100-, 200-, and 400-amp service. I'll bet my bobbysocks they recommend the 400 service to Jake. Our place in P'cola wasn't huge, but when we added the heat pump for the pool and the outlets in the garage, we had no choice but to upgrade from our 100-amp service (1960s house). The difference between the 200 service, which we would have maxed-out, and the 400 service was surprisingly small.

I miss that house.

For normal shop use I just have an underground 50 amp service running to the building from a circuit in my house. The highest load comes from my 220-Volt 80 gal 5hp air compressor. When I was planning the shop I was thinking about a 100 amp circuit and my electrician asked a simple question are you going to run everything at once. Good point! He assured me a 50 amp service would be enough. I do not have heavy equipment or hot ovens but I do have air tools, saws, welders, electronics, fridge, and fans. I have never had a problem or popped a breaker.
I have an electric breaker box in the shop that splits everything out in the shop. The air compressor has its own dedicated circuit. I have a row of lights hanging from the roof on its own circuit. I have a row of 4 gang electrical plug boxes 10 feet apart along each wall that has 2 pairs of plugs each pair on its own circuit. So I can have 2 always on plugs and 2 switched plugs in the same 4 plug box. Along one wall (the side of the compressor) I have a 1 inch galvanized pipe 46 feet long, set at a slope for drainage, with quick disconnect outlets for air and down pipes with stop **** to drain the pipe. I have a paint filter / dryer in line at one station for my painting connection. All lines are about 5 feet off the ground so they are not hidden by stuff in the shop and susceptible to water. Except for one shelf and the air compressor everything in the shop is on wheels.

Mike, does your shop have its own climate control?

Yeah, called the wind...

Got yourself some roof space on the new addition, any solar panels going there?

Saw some the other day that didn't even look like them.

great. more drama. Forklift delivering the foundation block discovered a septic system that I didn't know I had. Fortunately he was only startled when the lid collapsed and he was able to back his lift out of the hole. Somehow, he tried to blame Bonnie (my wife) for the situation when he contacted my builder! Funny. It wasn't anybody's fault and he only had a narrow access corridor due to the pile of stumps and roots on the edge of the access - he couldn't have driven anywhere else. Bonnie only asked him to not leave materials on the driveway so we can pull out but he claimed she was "coaching" him on where to put materials (like either of us have any idea where the guys needed the block, mortar and sand).

So, apparently my shop bathroom doesn't tie into the city sewer like the rest of the house - that was a little surprising. I'm fortunate on a couple of key points (besides nobody getting hurt) 1) the tank appears to be large enough to support the second bathroom upstairs (maybe even with a future shower should that be needed). 2) the tank is not under an area that will be paved with concrete but is in the middle of a small grassy area I was creating. 3) the drainfield did not cross the footers for the new building so I don't have to relocate it.

Are you going to Racine?

You're lucky. It could have been an old Hawaiian burial site which would mean years of delays, archaeologists doing a dig on your property, and being sued by every sovereignty group in the islands.

i think its a shyty turn of events, but glad it wont derail your plans.

glad no one was hurt. sounds like he deserved to fall in a little

no....but it's killing me.

My shop is open on the ends. I have mixed feelings about doors in a large shop in South Florida ventilation is important. It would cost an arm and a leg to cool a building like mine, then you would have to deal with the dust and chemicals so you don't blow yourself up.

Yeah, but if you went, not knowing what's going on with the construction would probably be worse.

I just saved myself a lot of headache by being here. Came home for lunch and I knew they were getting close to pouring the slab. I grabbed my camera, walked down the driveway and started watching the first of two concrete trucks back up (over my already busted septic tank...now the discharge pipe is certainly broken). I watched them hose down the chute to lubricate it for the concrete....saw the water dripping on the dirt....I thought dirt, water, concrete, moisture....moisture good for concrete cure. dirt.......moisture.......concrete.....CRAP! There's no vapor barrier!!!! As the guy has his hand on the dump valve from the truck I start screaming WAIT WAIT WAIT!!! Apparently, the "builder" didn't tell them they needed a vapor barrier. Had I gone to NA's in one year from now I would be wondering why my epoxy floor keeps blistering.

Fortunately for the builder, the concrete sub-contractor, and the concrete truck drivers (2 of them), they had the plastic in the truck and had it rolled out in about 4 minutes. Geesh. Every second I start to think I'm over-thinking everything I catch someone doing something stupid.
