I have an outdoor patio made of the red concrete bricks and 1 ft. x 1 ft. red concrete squares. Can I stain these to a darker color? If not, is there some other method of coloring these bricks?
Yes you can acid stain patio pavers but depending on the beginning color, the final color may be somewhat different from Acid Stain on regular gray concrete. Keep in mind that brick surfaces maybe more porous than a standard concrete slab so more than the recommended amount of Acid Stain and sealer might be required for the job.
Don’t forget to seal the surface after Acid Staining. I recommend the Sprayable Satin Finish Sealer or the DCI Water-based Sealer if you live in New England or California.
