Okay, I know that it's not a garage, but my concerns are the same. The size is only 118sqft, so I'm trying to find a sturdy, yet affordable set of products.
I have some small cracks and spalls that I need to fill. There may be some other grinding that I need to do.
I've been quoted 800 to get it done, but I feel like I should be able to do it myself for much cheaper. The problem is that the crack fillers and such are sold in much larger quantities than I'll need.
I've read up on epoxy VS polyurea and the merits of each. How do you all feel about them. Also there's a company called brewfloors.com that sells epoxy coatings.
So while I've just rambled on, what advice can you all provide?
This is an interesting request, and you have an opportunity to do something unique if you're interested. The proper product to use here would be a urethane polymer cement. Urethane cement is a mixture of binder (urethane), cement, and aggregate (decorative quartz being most common). This coating is usually applied between 1/8 inch and 1/4 inch thick, then a decorative quartz would be broadcast until refusal. Then a clear or pigmented polyurea top coat to lock everything in place and provide additional protection. Urethane cement is extremely impact, abrasion, chemical, and thermal shock resistant. It is mandatory in food processing and beverage processing facilities almost across the board. It is extremely, and I mean extremely easy and straightforward to install. Easier than double broadcast epoxy systems.
There are a few similarities and differences when installing urethane cement compared to epoxy. None being overly difficult, just a bit more time-consuming... but not much for the square footage we are talking about.
You will need to grind the floor same as epoxy, & Chase any cracks with a diamond wheel. For you urethane cement it is a good idea to key a 1/8" by 1/8" in scribe along the entire perimeter 6" from the wall for the coating to Anchor to. This is done with the same 4.5" diamond wheel used to chase cracks. Just key in around the perimeter and around any drains or floor penetrations.
The nice thing about urethane cement is primer is not required. If you have Expansion joints just fill them with 100% solids epoxy joint filler or a polyurea joint filler with sand.
You will mix a small color pack into your part A for 15 seconds, then you will mix Your Part B into your part A for 15 seconds, then you will mix cement into the liquid for 2 minutes. Your next step will be to apply the entire contents in a ribbon onto your floor and use a gauge rake to spread evenly. Gauge rakes are $40. You will then use a loop roller and back roll for thicknesses of 1/8 in or 3/16 inch. For quarter inch thickness a spiked roller is recommended, so I would recommend to stay in the 1/8 inch to 3/16 inch range so you don't have to buy any special equipment.
After you have completed your back roll you broadcast your decorative quartz until refusal into the wet coating. Come back the next day, or in some cases 12 to 16 hours later and roll on one to two coats of a polyurea to achieve a final thickness of around 16 Mils.
That is a bulletproof floor that can take extreme thermal shock resistance and will stand up to very acidic and base pH levels.. 118 square feet would be really affordable and very quick/fun to apply.
