What happens here

The presenter introduces the project of acid etching a garage floor to prepare it for industrial epoxy. He explains that a smooth concrete surface will not allow epoxy to bond properly, so etching is necessary to create roughness. He then demonstrates diluting muriatic acid by pouring it into a plastic pump sprayer. He mixes the acid with water, aiming for a ratio of approximately 75% acid to 25% water. He stresses the importance of performing this dilution process in an area away from desired plants or concrete surfaces, and to always have a running water hose nearby for safety.

Goal: Prepare diluted muriatic acid for application and understand safety protocols.

Tools and materials

  • Eye Protection — Protecting eyes from splashes and fumes
  • Muriatic Acid — Etching the concrete surface
  • Plastic Pump Sprayer — Applying the diluted muriatic acid evenly to the concrete
  • Respirator — Protecting lungs from acid fumes. Must have filters rated for acid gases
  • Rubber Boots — Protecting footwear and feet from acid splashes
  • Rubber Gloves — Protecting hands from acid contact
  • Water Hose — Diluting acid, rinsing spills, and washing the floor
  • Water Tap water — Diluting muriatic acid and rinsing

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
