Any guidance you can provide on prepping and painting garage floor is appreciated. Als, best materials to use. Thank you.
We also live in SE Nebraska. All the epoxy garage paint jobs (even by the pros here) seldom last more than 3 years. Amazingly that is the maximum guarantee that many provide. Our freeze cold/high heat/high summer humid climate just does not do well for concrete painting. We have 3 in our neighborhood whom wish they had not painted.
I think Concrete stain is a better option if you want the look.
If you have a new garage floor, allow it to age/cure long enough, (often a year?) to get rid of most of the "chalking" that tends to come off before applying any sealant. An old floor must be very clean, using cleaning solvents and a power washer to get all the soils/oils off.
A pro paint store like Sherwin Williams sells a concrete solid color stain that is a better choice than paint. It is applied to a power washed, clean and dry, properly aged concrete surface. Acid etching is applied and prepares the surface for the stain and rinsed off. You can apply transparent, semi transparent or solid color. Adding "Shark Grip" to the stain will help reduce slippery surface issues if you have a very slick concrete finish.
A clear finish coat can add protection or just the solid stain. Stain is nice, because it may wear away over the years and can be touched up (does not peel). Epoxy paint, once it bubbles and starts to peel, is a mess to deal with, trying to repair it.
What is the reason you want a painted garage floor? That might help determine what you can use. The painted floor is not any easier to clean, it does not keep dirt out of a houses and does not stop many cracks.
I'd agree with Conrad. I've seen several of the Rustoleum DIY kit jobs at friends and neighbor's houses and none have held up. There may be some industrial, professionally applied ones that work but I'm not impressed with the DIY stuff.
If you search the boards for posts by itsreallyconc you might find some products that he'd recommend. He's a professional concrete guy. He pops up once in a while, I haven't seen him here in a couple of months.
Any advice given here is general in nature and is not necessarily valid for your given area. If in doubt check with your local codes enforcement department for what is required when doing electrical, plumbing or structural work on your house. Permits may or may not be required in your area and home owners may not be able to DIY some tasks. I have no way of knowing if you have the skills needed to complete the tasks you are asking about, when in doubt seek professional assistance.
My advice may be worth exactly what you pay me for it. :-) For the record I did not stay in a Holiday Inn Express last night.
Found this great article with step by step instructions. May be worth giving a read.
