## Description

How To Use: Floor PrepThis is the most important part to any concrete floor. We highly recommended renting a swing machine and placing a 16 Inch 30 grit Concrete DNA Satellite Pad (ASIN: B06XXC1VVV ) in combination with our Super Blue (ASIN: B01H7KGEUA ) diluted at a ratio of 1:9 1 gallon of Super Blue to 9 Gallons of Water. This will open your concrete so the stain will be able to penetrate the surface. We also highly recommended at this point to use our Citra Peel (ASIN: B01H7VFO1O ) and a Black Pad to remove any sealer that is on your concrete floor. All sealer must be removed or the stain will not be able to penetrate the concrete. Applying The Acid Stain:Apply the stain with a pump sprayer. You should cover your floor until there is 100% coverage to the entire area. DO NOT change up how you apply your acid stain during the project, it will cause a different look when you change applications methods mid-stream. Allow to dry thoroughly. Reaction/Drying time will vary according to surface conditions and humidity. Once the stain is done reacting typically between 2 to 8 hours the floor should be rinsed with water or a wet mop to get any residue left behind by the acid stain.Allow the concrete to dry completely, typically 24 hours Run your finger across the floor to make sure you got all the acid stain residue off the floor. Now it is time to apply your sealer. We recommend Ez Seal which will “pop” your color (ASIN: B01H7L8G3M). Finally we strongly recommend on interior application to protect and keep your floor looking new our Ez-Glo Floor Polish (ASIN: B01H7MJ8JM) or Ez-Glo Floor Polish in Matte Finish (ASIN: B06XWYBBXQ).

Review: Great quality stain -a little goes a long way - So I did an overlay with a concrete countertop and used this acid stain. It turns yellow when you apply it. But then it quickly changes to brown. The first time I sprayed it I just used the full concentrate and it made my countertop a dark walnut brown. But then I played with it and watered it down and the color was a light choclolately brown. It was gorgeous. A little of this product goes a long way. I only used about a quarter of a gallon for 2 10 foot countertops and one smaller one. The first time I painted it on and there were some brush marks. The second time I watered it down and put it in a spray bottle. Pros High quality. A little goes a long way. Beautiful color Cons It will stain everything in sight and it is difficult to remove. But it is a "stain" so prepare your surfaces accordingly.
Review: Buy another brand - Tried a new brand and it was terrible compared to other brands used in the past. Almost no color when applied to 6 month old unsealed broom finished concrete. Have never had this occur in the past. Pay a few extra bucks for the competition. This stuff is garbage.

### ⭐⭐⭐ Be very careful with what you order
*by A***S on September 7, 2024*

This was my fourth bottle of this stain. I actually ordered two bottles in this last purchase. The first bottle did fine just like the bottle prior the second bottle, however, actually started smoking on the concrete and had a bad odor when we came back out the next morning to check the concrete that has been staying with the second bottle, it was completely white stain unlike the other bottle. Now I gotta figure out what I can safely put on the concrete to re-stain it if possible! I tried reaching out to the seller through Amazon, but it’s complicated task as this has a no return policy. I don’t want return. I want another bottle correctly mixed to put on the concrete.
