Instructions & Tutorials Preparing Concrete For Epoxy. Acid Etching Hacks.

What happens here

The video introduces the process of preparing a garage floor for industrial epoxy coating. The presenter explains that smooth concrete needs to be etched to ensure proper bonding of the epoxy. Muriatic acid is presented as the chosen etching agent. Safety measures, such as wearing rubber boots, having a water hose readily available for spills, and using a respirator with appropriate filters, are highlighted. The presenter also advises against using the acid on concrete outside the designated area and to use a plastic pump sprayer as the acid corrodes metal.

Goal: Understand the process and prepare for safe acid handling.

Tools and materials

  • Eye Protection — Protecting eyes from acid splashes
  • Muriatic Acid MR. CLEAN — Etching the concrete surface to create a rough profile for epoxy adhesion
  • Plastic Pump Sprayer — Applying the diluted muriatic acid evenly to the concrete surface. Must be all plastic to avoid acid corrosion
  • Respirator with Acid-Grade Filters — Protecting respiratory system from hazardous acid fumes, especially in enclosed spaces
  • Rubber Boots — Protecting feet and lower legs from acid contact
  • Rubber Gloves — Protecting hands from direct contact with acid
  • Water Hose — Diluting accidental acid spills on plants or skin, and for rinsing the etched concrete
  • Water Tap water — Diluting muriatic acid for application and for flushing spills

painter. In this video, we're going to show you how we go about prepping a garage floor to get it ready for epoxy. We're going to be putting on an industrial epoxy from Sher Williams. And the floor itself, we're going to be taking using moratic acid to etch the floor because the concrete, if the concrete's too smooth and it's not rough enough, the epoxy won't bond to the concrete. So, we're going to show you how we go about getting it ready. I've got moratic acid and this is what we're using to etch the floor. And I've got a a plastic pump sprayer and I actually add the moratic acid into the pump sprayer. And I typically don't use it 100%. I use about 75% acid to 25% water. And I'll show you. We're going to go ahead and mix our acid and water together. You want to make sure you don't use this acid anywhere on the concrete anywhere. You want to do it someplace where um it's not going to kill any plants or cause any problems. And just in case you spill it and I'm over here on the side of the yard that it doesn't matter if I get the acid on the ground. And the acid just for safety reasons too. Uh we've got a hose sitting here right here. And the hose just in case you spilled some acid or something the hose the water will dilute the acid. You want to use a sprayer that's all plastic. If you get a metal sprayer, the acid will uh ruin the metal. So, we use a sprayer that's all plastic with plastic tips. I'm going to be using rubber boots this whole time, too. If you just wear regular shoes, the acid could ruin your shoes. I've got water here running just in case I get any on my hands or anything. I've got a respirator that you definitely want to have filters that's um good enough for the acid because once you start working inside the garage, the acid's going to be pretty hard for you to breathe. I just filled my bucket up. I'm going want to wet this area around here just to dilute
