I have a 800 square foot garage floor that I plan to put Epoxy paint on. I am thinking of using the Sherwin Williams brand but am not sure. I would appreciate other people's professional opinion that have done this type of work. Could you tell me what has worked for you and what has the best durability as far as wear and tear.
Also, what would work best to fill in cracks in floor?
Thank you!

First you are going to have to clean the heck out of the floor and etch it with muriatic acid. Neutralize with baking soda and water then rinse. Let dry a couple days and put down a concrete bonding primer using a sponge roller. Let dry and put down another coat going the opposite direction. Let that dry 8 hours or more. Now you can paint your epoxy coating on doing several light coats and changing direction between coats. I place all my rollers in plastic bags in the fridge or freezer between coats.
After 72hrs of curing seal with ZEP high traffic floor finish using a large grout sponge to apply.30 minutes between coats and about 4 coats. Place sponge in plastic bag between coats. I only mop my epoxy floors with a damp mop and apply another coat of Zep every 6 months.
