Rust-Oleum 238475 Concrete Preparation Etch, 1 lb

I bought two, since I have a two-car garage. I power-washed my garage floor twice. One side had a few paint splatters on the floor, nothing big, but the other had a few oil stains. After heavy cleaning, I applied the concrete etch. I used a metal watering can that holds two gallons of water and mixed it in with the concrete etch. I poured some on the floor, let it sit for about a minute or two and then began scrubbing. I missed scrubbing a few spots and you can tell, once it dried. Nothing bad, though. I first wet the surface, lightly, then applied the etch. Let it sit for a minute or two, scrubbed, and then moved on to the next section. When done, I rinsed the whole floor. I had a squeegee to wash/clean a car's windshield, and put it on a pole. I used it to pull out all of the water from the garage floor (not all, but 'most'). I then gave it another rinse, to ensure I didn't leave any etch on the floor. After it dried, my garage floor went from a dark gray to almost white, which is what you want! Unfortunately, some of the etch pooled at the end of my driveway and dried, so I have a white spot at the end of my driveway (which is asphalt). Not a biggie, I'm sure the rain will eventually wash it clean.

I used EpoxyShield Concrete Etch prior to applying a coating of Rustoleum Professional Floor Coating Kit, Silver Gray. After use, the concrete no longer had a shiny surface, and it looked very clean. The real test was two months after I applied the epoxy - it was adhering tightly, and did not peel off even under the car tires. Preparation is the key to good epoxy adhesion. This product was important in preparing properly. I liked that it was not toxic or dangerous, but still prepares the concrete well.

It works, in some spots of the concrete I can clearly see the pores opened from this product. Out of hesitation I rented a concrete floor grinder from the orange home improvement store. The 2 hours I spent with the concrete floor grinder was a better use of my time than the 8+ hours I spent decreasing the surface plus the 2 hours I spent using this product. The concrete floor buffer I rented weighted about 180 lbs and was a beast to unload and load. It was easy to use otherwise, completely worth it in the end for my situation. This product has its place, but if any amount of degreasing is necessary this route may not be worth the time. If you have a fairly clean slab to etch, then this is the product for you.

On the front end, this appears to be a great product- affordable, easy to use , clear instructions... Other competitive products do not include their ingredient- this does. We used it on 4 year old patio cement for staining. Test of time will tell.

Follow the instructions and it works the way it should. I used a mop for the rinse and clean up steps because I was working in a fairly small space and don't have a squeegee but it worked fine. It didn't seem like the 1 - 2 minute set time they suggested would work, but it did.

I used this on my basement floor before using Kilz garage floor one part epoxy paint. I followed all the directions to a t. It was a PAIN IN THE REAR, but you know what? I go EXCELLENT results. My floor looks amazing and the paint stuck so we'll.

Just like Rust-Oleum EPOXYShield Heavy-Duty Degreaser in the cases of bad grease/oil stains, this EPOXYShield Etch is absolutely necessary to ensure proper adhesion of Rust-Oleum Professional Floor Coating Kit . After you've hosed down and removed the bulk of the debris from the concrete you wish to etch, mix this up as directed and apply. As is stated on the directions, using a watering can will help evenly apply the etch solution. You should hear it "bubbling" which sounds like a freshly poured glass of pop (cola). Let it sit for a minute or two, then scrub, then rinse. The concrete may appear to be a bit dull after application of this but that's what you want for proper adhesion of epoxy! I've used this product time and time again and have yet to have a bad result. I only wish the kits included the etch (they used to a few years back).

Doesn't work...I had to grind my concrete down in the end...

Good product!

J'ai utilisé ce produit afin de faire une nouvelle couche sur le plancher de mon garage. J'ai laissé le produit agir pendant une couple de minutes tout en passant un solide balai-brosse. l'adhésion de la nouvelle couche a bien adhèrée à l'ancienne. Le seul point négatif est que le produit s'est écoulé sur le revêtement de l'asphalte et maintenant je vais donner une nouvelle couche de revêtement à mon entrée d'asphalte. J'aurais dû arroser abondamment mon entrée pour neutraliser le produit.

Seller was great. The etch is a joke. New pad, followed instructions to the letter. Just about zero change to the floor after "etching" with this product. Rustoleum says "Do Not Use Muriatic Acid" andnafter some research and talking to Rustoleum employees i found out its due to there view of it not being as environmentally friendly. I tested muriatic acid on a small partnof my pad. Night n day difference. I used muriatic acid on the entire pad. Rinced. Neutralized with baking soda. Scrubbed/rinsed again. Used Epoxy Shield gargage floor kit. Waited 24 hrs and used the Premium Clear Kits. Love my shop floor. Using Rustoleum clost me roughly $1000 vs $12000 for the cheapest pro job (2000sq/ft shop floor)
