What happens here

Wearing all safety gear, including a mask, safety glasses, gloves, and rubber boots, the presenter begins applying the diluted muriatic acid to the garage floor using the pump sprayer. He starts from the back of the garage and systematically works his way towards the front. He advises paying extra attention to areas with tire tracks and contaminants, as these areas need more etching. The acid reacts with the concrete, causing bubbling and a yellow tint. He reiterates the importance of good ventilation by keeping both garage doors open.

Goal: Etch the entire concrete floor for optimal epoxy adhesion

where you're actually going. Now I'm going to start applying my acid. I'm going to start in the back of the garage. I'm just going to be working my way to the front. Once I get the acid all on the whole floor, then I'm going to rinse it out. Okay, here I'm go. I'm ready to go. Got my mask on, safety glasses, rubber gloves, got my boots on, and we're going to start this acid into when applying this acid. Wow. Wherever the um tire tracks are where they come in the garage, that's where you really want to etch it the most. If there's any contaminants, also spray a lot right there to really get those contaminants lifted up and etched out. But pay really good attention to where the tires come in. That's where you really want it the roughest. Also, make sure you have it well ventilated. I got both garage doors open and the other garage. If you got windows and stuff like that, make sure it's open, too, cuz you need a lot of ventilation cuz there's a lot of this chemical and you don't want to breathe this stuff. It's pretty nasty.
