Hydrochloric Acid 5L
Hydrochloric acid was historically called acidum salis, muriatic acid, and spirits of salt.
A 10-percent solution of hydrochloric acid is a good cleaning agent for brickwork. Typically bricks become stained due to mold growth, formation of mineral deposits, and contamination. It is important to prepare the solution properly, as the acid cannot be directly applied to the brickwork. A solutions of 9 parts water to 1 part acid applied to a rag or sponge can be applied to the brick to scrub away any imperfections.
Pools can be cleaned with the help of detergents and scrubs, but some of the staining is not easy to remove. You can treat dark stains that adhere to the grout in between the tiles with hydrochloric acid. When using the product for pool cleaning, make sure you do not apply it directly. The same 10-percent solution mentioned previously should do the trick. Alternatively, you can follow the chemical manufacturer’s recommended mixing procedure.
Alkalinity in masonry causes problems when applying paint or sealers. It prevents the coating material from properly adhering to the surface, therefore requiring neutralizing procedures. To neutralize the alkalinity, you have to apply hydrochloric acid solution to the entire surface before applying the coat. This will help the coating material bond with the surface.
