Another project underway... searched but still have questions
Hello to all.
Long time lurker first time caller.. err, I mean, poster! Been reading non-stop for the last two weeks and looking for some guidance and assurance. The garage is in the batter's box so-to-speak, so the 20 year old cabinets that came with the house were demo'd, the stucco walls were cleaned, painted, new shelving went up, mobile workbench/toolbox is in the mail, and now it's time to make the floor nice and shiny!
Current conditions:
- South Florida
- Semi-detached 2-car garage, 21 x 20 so 420 sq.ft.
- Humidity was a problem in the garage recently resulting in some mildewy cabinets, tool bags, etc. until a beautiful new dehumidifier arrived last week. That thing is wonderful. Seems to keep it anywhere between 20-50% relative humidity, whatever I set it to, even when its 75%+ RH outside. Neighbor is a PPG paint territory rep and he may or may not have provided some branded temp/RH monitors. Thanks neighbor
- I'd like to think concrete is in pretty good shape for 20 years old. One apprx. 11' crack I'll picture, couple small spots of spalling from the pressure washer and few chip marks here and there. Did have some heavy oil stains from old leaky antiques but they seemed to come up with degreaser and a pressure washer. There is what looks like a burn or rust mark in one spot but not sure what it is.
- Concrete has a damp ring around the perimeter of the interior but moisture test with plastic sheet revealed no moisture in three different spots. I'm fairly confident the dampness is coming from the humid air within the garage. I say this because if you place an oil jug, or any container, on the floor for a day or so and then move it the concrete is dry where the container was sitting in a perfect footprint while the damp concrete around remains. I've had the dehumidifier about a week and only running it to one tank full per day the ring is starting to slowly dry. I have not set up a drain hose to try and run the dehumidifier continuously yet.
- I have noticed some fibers in the concrete showing. First noticed it when scrubbing or pressure washing in the past, under where the cabinets were mounted on the wall. Not sure what that means, if anything.
Needs:
- Nice clean floor
- Can withstand two parked cars being parked or moved with wide hot summer sport tires
- Can withstand the occasional 3 ton jack rolling around and jackstands for oil changes here and there, minor projects and inevitable spills: Brake jobs, gear box fluid changes, etc. I'll be replacing current jackstands with the flat bottom types
- Scratch resistant
- As little down time as possible as I have no safe place to park the cars since the neighbor's kids are wild
Wants:
- Preference of solid color, no flakes, metallic would be nice but not needed
- I like glossy finish
- Must be scratch resistant, I know lots of abrasions/scratches will drive me nuts
- Some anti-skid would be nice for all the Florida rainy seasons but not a deal breaker
- Light gray colors preferred, dove grays look nice but unknown if they're able to stay nice looking, medium grays are fine, dark grays and charcoals are not preferred
Current Plan:
- Rust-Oleum Concrete Patch & Repair for the crack and the small spalling and couple chips
- Hand grind with angle grinder using diamabrush disc, Dustbuddie XP shroud
- Probably purchase Dustless shop vac to facilitate easier cleanup and looks like it can do double duty afterwards for around the house cleanup. I need a big shop vac anyway
- Cheap 4" angle grinder with some type of cup attachment for smoothing out repairs and hard to reach corners and along the walls
- I don't have any angle grinders so I'll probably buy them to have them for the future. Depending on how this goes I may want to do some type of coating on first floor of the house so it may come in handy sooner than later.
I did initially want some type of polyaspartic as the downtime was ideal. This is my first go at this type of project so I realize it may not be ideal. Even with the polyaspartics, it bothered me there was no epoxy primer layer recommended (Shea, thanks for the website you got me set on an epoxy primer
)
I was thinking epoxy primer, then at least two coats single part polyurea
Or
Single part polyurea kit only.. is this an issue with the damp concrete?
Looking at some of the main vendors, I couldn't help but notice the Norh-S system provided an epoxy primer, three total coats vs. two, and light grey color. Down time not ideal but not as bad as regular epoxy from my understanding. So I've been leaning toward Norh-S but not settled on it quite yet and can be swayed by your good advice!
Questions/concerns:
- Corners will be ungrinded wherever a 4.5in grinder can't reach.. is this an issue? Will pressure washing in 6 months or a year peel these corners up?
- Entrance has a little 1 or 1.5 inch lip. What's the best way to prep the small vertical surface?
- I have two metal plates that are fastened to the concrete at the entrance for installation of hurricane shutter type bracing for the garage door. They're about 4x4 in size. Should I scuff and paint over? Paint around? Again, my fear is pressure washing down the road.
This sound like a solid plan or does it need some tweaking? Any other coatings I should look into or you recommend? Thoughts on the damp concrete?
Thanks in advance, much appreciated!
