I'm buying a new house with an attached 2 car garage and I was planning to seal the floor before moving in. I've seen some DIY epoxy paint kits at the big box stores for around $100, and I've also seen kits for as much as $500. I'm wondering if anyone here has used these kits or any similar epoxy paint for their concrete floors. How do they hold up? How hard is it to apply? And do you have any recommendations. Any assistance is appreciated.
