I noticed you didn’t scrub the floor, is the scrubbing not needing? How long did you let the acid sit once you applied it with the pump sprayer? Thanks buddy great video!
what a great how to video. i work for a bldg solutions co. in toronto canada, and you are about as good as it gets. you should be going around the world training company employees, and making skids of money. preparation is everything, and you left nothing out!! your a big asset to the construction industry, and i hope everyone sees your video!!! cheers brother.
My question is who was you teacher Idaho??? Because you are so professional every single video you Surprise me the way you work 👍 I’m painter to for 10 years state California I always watch you videos to do my jobs when I have questions
When you begin the rinse process, should you be worried about the water splashing residual acid onto the walls, shelves, or wall-mounted benches? I noticed that none of these were covered nor were their contents removed.
This is the process if the floor is already clean right? What are your tips if the floor has had sheetrock mud and paint drips, plus dust from sanding?
Thanks for this video. I have done a lot of projects my self, and with my wife, but this one for my garage i wasnt to sure of and didnt have the confidence to attempt it. Now that i have watched all the epoxy floor videos i am sure i can do this one! Thanks for all your vids, and keep doin em, they will be your legacy, thats how us old guys think. Perhaps you should make your own home improvement Blu Ray or DVD and pass it out to your family at Christmas...... Thats what i did, Legacy, its what old guys think about! Awesome videos for Epoxy garage floors, thanks again, Mike
Very helpful...couple of questions though. Is it not enough to just use a pressure wash nozzle on the hose? Or do you really need an actual power hi pressure washer too? Also, sure seems like he would be getting all that stuff in the garage wet. Might want to "hang" some plastic sheeting first, right? I'm gonna try Rustoleum EpoxyShield which comes with an etching product in powder form (add to water) so won't be dealing with muriatic acid. But for those who are, it would be helpful to give the dilution ratio of water to acid. Thanks!
My house is 40 years old and the concrete in the garage was once painted but most of it has worn away. Should I use a concrete sander and if so do I still need to do acid etching? Or should I skip the sanding and just scrape up the paint, degrease and then acid etch? Your videos have been very helpful.
The price to rent a pressure washer with sufficient pressure to have half a chance of stripping the paint would cost just as much if not more than renting a concrete floor grinder. Odds are the pressure washer may take off a fair bit of it if it is flaking but is unlikely to get it all, on the other hand the floor grinder will remove the paint, and it will prep the surface and open the pores in the concrete to accept the new paint which the pressure washer will not do.
You don’t make any mention of what concentration of muriatic acid you’re using? One gallon can have a range of 14% up to 33% muriatic acid. The big box hardware stores usually sell 14% concentrate. A pool store sells 33%.
I'm going to do my garage floor this week , my Gyrock doesnt go right to bottom of floor , it's about 4 inches above floor , should I do the sides of the walls the 4 inches??
@@MuahMan A small drop of water has all the acid to react with it, all at once. That can be violent. The reverse means that a small amount of acid meets a large amount of water - much safer. The risk is the heat of reaction. A large amount of heat is released when strong acids are mixed with water. Adding more acid releases more heat. If you add water to acid, you form an extremely concentrated solution of acid initially. So much heat is released that the solution may boil very violently, splashing concentrated acid out of the container.
Acid is denser than water. If you add water on top of acid, it can sit on top without mixing. There is a lot of heat released when the acid is diluted by water. If it is concentrated in a single layer, it can get get so hot in that layer that it boils and splashes the mixture out of the container.
Or diamond grind the floor so you don’t have to deal with acid and your floor will stick indefinitely. If you diamond grind the floor, you can coat it immediately after with no hazardous materials and environmental contamination. The acid lays in those joints and will rear its ugly head later.
I'm wanting to epoxy my concrete garage floor and stain the concrete immediately outside the garage. It's my understanding that the muriatic acid will cause problems with the staining process. Will washing out the acid from the garage onto the outside concrete cause problems with the process of staining, or will it be too diluted with water to cause any negative effects?
hey great videos I've been remodeling the entire garage and finally got to the point to do the last thing which is epoxy the floor...I live just south of Houston Texas...I was wondering what epoxy you use/recommend? I'm planning on doing it in the next couple of weeks..thank you
I have been also taught to agitate oil spots with hard bristle brush and top & bond any large salt pocks/ chips...what is your take on this? keep up the good work!!!
everyone is saying not to add water to acid...is it then 100% safe to rinse the acid on the floor with water while trying to remove the acid from the floor?
I noticed you didn't tape off the walls or trim? Is this something you should do? Also, how long should you let the Acid sit on the Concrete before you start diluting it? I noticed you started on the back corner and worked your way right to left, but then you diluted the acid from front to back meaning some of the acid was sitting longer than other.
Video's are great--Question...what about moisture coming up through the cement floor? I live in upstate NY and temp's vary from 110 in the summer to -20 in the winter and it is usually very green around here...(plenty of rain). Several video's raise the question about epoxy lifting away from the cement.
Nice work , what do you think about the porch and floor paint by sherwing williams? and Does it have the same performance and effectiveness as the epoxy in the concrete? thank you
i have a concrete floor in a restaurant so washing with a hose then pressure washing isnt possible, would a mop and water bucket work to wash away or dilute the acid enough to paint it if i mop it out a few times? thanks
G'day, If I'm painting brand new freshly laid concrete. It's dried concrete only a couple weeks old. Do i still need to acid clean it?? Or can I etch it then begin coating?? How many coats do you do?? Always 2 coats?? Allowing each coat to dry atleast 8 hours?? Appreciate the assistance
the p[revious owners put some cheap coating down. im assuming i need to diamond grind the concrete to remove the old paint and ruff up the surface. I do not need to use acid correct?
in case anyone was wondering this is an amateur method. Next he'll be installing a water based epoxy. aka glorified paint. Diamond grinding then polyaspartic for the win.
I want to do this on my floor of my laundry room in my basement. There is a drain in the floor. Will the acid be a problem going down the drain? Thanks.
wranglers2 a lot of people neutralize with baking soda. However, if you are doing epoxy it is better to grind down the concrete. Unless you want to wait a while to do the actual epoxy. When they water you have saturated the masonry with evaporates, it can leave bubbles in the epoxy and sealer. Etching is only beneficial when staining masonry. Check out www.ez-concretesupply.com .
Hi, I painted my garage floor about 10 years ago with the Rust-Oleum 2 part epoxy. Over the years it has gotten to the point that I need to coat it again due to the floor being dirty and some of the paint coming off. I recently pressured cleaned the floor and got about 30% of the paint off doing so. My question is, do I need to remove the rest of the epoxy paint off or can I just paint over it? If I need to remove the rest of the epoxy paint how do you recommend doing so? I used a 4000 PSI 4GP pressure washer with a turbo nozzle and was only able to remove about 30%. I know Lowe’s sell a primer for floors that are already painted but since my floor has about 30% of the paint removed I’m not sure if I should go that route. Ant suggestions would he highly appreciated by anyone. Thank you.
What do you do in the case where you want to have epoxy floors in the interior of the house. obviously flushing the acid out is a problem, would sanding be the best option for prep? thanks
Excellent video!!! One question, my sealant seams to be incredibly durable. Have you ever encountered a sealant that was not removed with the acid you showed? I was tempted to remove it physically but would rather acid etch if possible. Thank you so much in advance!
Hi, everything I am reading about is telling me diamond grinding is better than acid. Is this true? Acid is more convenient. I don't mind renting a machine and grinding, but it it's not much different I'll stick to acid
We did diamond grinding on our living room floor, but the corners and edges are left. I am going to try the chemical for those spots. Since it is inside the application and rinse will be in small areas so I can control water inside my house. The diamond grinding can be very dusty. My husband did the grinding, I used a hose to keep the floor wet and the shop vac to suck up the muck. This kept the dust down during the process. also covered openings into living room with heavy plastic, the fireplace, and partly up the walls. When the muck dries it is dust and can be wiped up but it is fine and too much makes a mess.
Idaho painter is awesome. Definitely appreciate the painting help in other videos. But please everyone understand. Painters and professional floor coating companies are not the same thing. Diamond grinding > acid etching. Get your floor coated, not painted. The difference is your floor lasting and looking great after decades instead of only a few years.

Why did you not tarp the shelves and cabinets?
I see that nothing was covered up. I’m guessing it doesn’t hurt the trim, painted walls or anything with overspray?
How long do you leave the acid on the floor?
Also can you do this over a previously painted floor? Thanks 🙏
No - you have to mechanically remove the old paint with a grinder or something like that.
No part 3. Parts 1 & 2 are awesome. Will keep tuned in.

Glad you think so!
You don't use a degreaser?
howdy, dont you brush it afterwards instead clean it with water?

What is the mixing ratio of the acid and water?
Would splats and patches of water based latex paint keep a water based epoxy from bonding to a concrete slab that's been diamond grinded already?

Excellent info. Great safety info as well. I'll use this.
So you don’t need to scrub the acid in? Just let it do the work?
Great video, i plan on doing this to my garage. What is the ratio of water to acid that you used
Literally was going to ask you if you had a video of this as I was prepping a floor today. Thanks!
as a very important note ALWAYS ADD ACID TO WATER . NEVER WATER TO ACID , you can get a very violent reaction it you add water to acid
Chemistry class
Thanks. I didn't know this. Nerd in me wants to know what would cause a violent reaction with water? Because of iron and stuff in the water?

Will washing out the acid from the garage onto the outside concrete cause problems with the process of staining, or will it be too diluted with water to cause any negative effects?
Apply acid with a roller to avoid aerosolizing the acid spray and getting acid on your skin and other places.

Love your videos Chris. Thanks.
What type of epoxy did you use?
I have paint on my garage floor. Should I use paint stripper before applying the acid or could I just use the acid?
painted floors are usually grinded, instead of acid. grinding will remove the paint entirely, acid will not unless you do it multiple times.
Hey how long do you wanna leave the acid before you wash out
As soon as I spray the whole floor I wash it off
Do you do the same process for a brand new floor?
