Etch and Clean is a concentrated, acidic cleaning solution that produces a light etch. The material uses phosphoric acid to lightly etch the surface and remove mild efflorescence. Using phosphoric instead of muriatic acid gently increases the porosity without damaging the substrate, therby allowing better penetration.
Application:
Dilute the material as described. Test Etch and Clean to assure compatibility. Pre-wet surface with water. Apply with pump sprayer and scrub with nylon brush. Do not allow the solution to dry on the substrate. Once cleaning is complete, pressure wash or scrub with clean water, rinsing away all the cleaning solution. Let dry completely before application of coating or stain.
I have used concrete sealer on my decorative concrete patio for 10 years. Is it safe to use concrete sealer remover to get rid of the old sealer and then reapply new? If so, what would you suggest?
What type of sealer are you removing? Pics would help as well. Thanks
