How Do You Fix an Acid Stain That’s To Dark?

stain that's too dark

Question:

Hello. Using your Cola Acid Stain on an outdoor patio for a customer and the sample patch was a little dark for their liking. To get a lighter shade should I wash the stain off earlier to stop the reaction, put it on damp concrete, or dilute the stain before applying? Thanks for your time.

Answer:

Great question! Our concrete stains utilize a chemical reaction to transform an ordinary concrete slab into a one of a kind luxurious looking floor for a fraction of the cost. The single component stain reacts with the concrete to form a variated color effect.  This stain will not chip or peal from your concrete surface.  The other benefit of our stain beyond its high strength formulation is that it does not require neutralization like many other acid stain products on the market. This is very durable outside and will also add great beauty to their patio.
There are two ways you can take a dark stain and make the final shade lighter. First option would be to dilute the acid stain itself. Second option would be to wash the stain off earlier in the process. In addition a second test patch should be done before completing the project. As a result their outdoor patio will end up with a lighter colored coating.
