You need a secondary containment basin, I suggest a HDPE tub. Applying a coating is not going to stop water from entering your joints. Vinyl tile is not a good flooring option for continuous water exposure.

Penetrating sealers should not have an issue with power troweled concrete. I apply penetrating sealers to 1500-3000 grit polished concrete with no issues. Spray on until concrete is saturated, mop with clean microfiber mop leaving no puddles. Waterborne sealers will dry very fast...

Your tires are not going to get hot enough in WA to pull the coating up, especially properly installed.

Which topcoat is it getting? Why isn't that in the quote? How many coats of 646? 646 is like 72% solids, concrete floors should be coated with 100% solids epoxy. 646 is okay as a primer, but you would need 2-3 coats to get rid of grinder marks and concrete anomalies. I would not suggest going...

I'll take the opposite stance lol. I always bring mine out to where the slab ends. If you do end it under the door or before the door, I would suggest cutting a very straight 1/8" deep line with a masonry blade as a termination joint, or else it will probably start peeling up over time. Your...

Resin bonds will polish or (hone) your concrete, essentially closing up the pores. It is necessary to use metal-bond diamonds to achieve the correct concrete surface profile and remove the "cream" layer. Go with option #3, that's $7.12/sq ft and a fair price. Tnemec is a fantastic industrial...

You definitely want to grind. Whether you rent a large grinder or do it with a 7", that is up to you. If you do use a 7" be absolutely sure you have a powerful vacuum (~200+ CFM) and a vacuum shroud to **** up the dust. You will have excess concrete dust because it spins so fast. Make sure you...

This is why a primer is recommended. The concrete is absorbing your epoxy in these areas.

Requirements for this new floor: needs to look nice can’t be slippery when wet due to motorcycles easy chemical cleanup (oil, brake fluid, cleaners, etc.) color stable – no yellowing. This shop has big windows. Nice to haves for this new floor: metalwork friendly. If I have to use a welding...

I got lung cancer watching that video. I am glad you are happy with your result, but those guys took time off their lives specifically not wearing respirators during the grinding process. What did they tape off exactly?

Use a 17 inch swing buffer with a red buffer pad and 80 grit paper for your initial sand. Once you have done both ways, switch to 150 grit and sand it all again. That will give you a nice new surface to stain.

Here is a job i did years ago for a customer in a similar situation. They had some guy come in and put down a floor in every wrong way possible. The solution is to grind it up and do it right.

This customer wanted it everywhere in their cabin.

Wow, great post! Thanks for posting all of the pictures and linking the data sheets to the products that you would like to use, saves a lot of time. Yes this would be a great system for exterior. Keep in mind any exterior coating system is going to be subject to more exposure from mother nature...

Sikaflex 1cSL. Only use a flexible polyurethane sealant. Any latex caulk will fail. Alternatively, if you have asphalt that butts to your garage floor, a pourable cold tar will work well.
