Hydrochloric acid cleaning pavers.
Austral bricks have provided an informative booklet on cleaning of clay masonry which includes cleaning pavers using hydrochloric acid.
I went to homebase and while their patio cleaner seems to have some kind of acid in it it didn t tell me which one.
You want a white foaming action when the acid is applied to the pavers.
Muriatic acid sometimes also referred to as hydrochloric acid is a strong acidic solution that you can use safely when you dilute it.
Therefore only pavers that have been wet bedded may require acid cleaning.
Apply paving sealer to area with either light broom or roller.
Use 8 parts water to 1 part hydrochloric acid solution you may have to increase the strength if the marks haven t been removed the stronger the solution the coarser the paver will become exposing the materials of the paver.
Mix hydrochloric acid and water ratio 15 1.
If the mixture has a yellow tint to it then you may add more water.
Remove paver stains with acid.
Add about 3 gallons of water to the bucket at first and then the entire gallon of acid.
Ensure pavers are clean and completely dry before sealing and that no rain is forecast for 24 hours.
Cleaning effloresence and stains from pavers is easily done using an acid wash which requires only a broom hydrochloric acid and water.
I have had a problem with my pavers laid 6 months ago and have been told the best option is to clean them with hydrochloric acid.
Just wondering if anyone know of a high street product that has this in it.
Dip the brush in and scrub a small surface on the pavers.
Wet the pavers with a garden hose.
