Covering up to 200 sq.ft. per gallon, it’s ideal for both interior and exterior floors and requires no neutralization or intense scrubbing. Compatible with sealers like Ez Seal and floor polishes for a polished, long-lasting look. ## 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: Product did not stain concrete - I have used another brand of concrete acid coloring for years that worked great. I decided to try a new brond as I wanted the Dark Walnut Color. It turned the concrete a faint light green. I would never buy this product again. Note that you can't return this product. ## Features - Concrete Acid Stain - Natural marbling effect. - Chemical Reaction so the stain is permanent. - Professional grade product that anyone can use. - UV Stable - great for interior and/or exterior applications. - Doesn't require any neutralization or intense scrubbing. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01D5F68TS | | Additional Features | UV Resistant | | Base Material | Concrete | | Best Sellers Rank | #764,467 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #1,320 in Household Stains | | Brand | Concrete Floor Supply | | Brand Name | Concrete Floor Supply | | Coating Description | Ez Seal, with additional sealers or floor polish for interior applications | | Color | Dark Walnut | | Compatible Material | Concrete | | Container Type | Jug | | Coverage | Up to 200 Sq.Ft. per Gallon depending on Porosity | | Customer Reviews | 3.5 out of 5 stars 14 Reviews | | Finish Types | Matte | | Liquid Volume | 1 gallons | | Manufacturer | Concrete Floor Supply | | Manufacturer Part Number | Acid Stain | | Material | Water Based | | Material Type | Water Based | | Model Name | Dark Walnut | | Model Number | Dark Walnut | | Number of Items | 1 | | Recommended Uses For Product | exterior, interior | | Size | 1 Gallon | | Surface Recommendation | Floor | | UPC | 787639248545 | | Unit Count | 128 Fluid Ounces | ## Product Details - **Brand:** Concrete Floor Supply - **Color:** Dark Walnut - **Material:** Water Based - **Model Name:** Dark Walnut - **Surface Recommendation:** Floor ## Images ![Concrete Acid Stain | Dark Walnut 1 Gallon - Image 1](https://m.media-amazon.com/images/I/41CRDPExgDL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great quality stain -a little goes a long way *by A***A on August 22, 2017* So I did an overlay with a concrete countertop and used this acid stain.
