For Brick Cleaning & Etching
Remove lumps of cement with a scraper. Wet bricks thoroughly with water to prevent acid soaking into the bricks – failing to do so could result in bricks turning yellow/ green. Mix 1 part Hydrochloric Acid with up to 10 parts water. Apply acid solution with a broad brush and then rinse off with water once chemical reaction (frothing) has ended.
As a pH Adjuster for Pool Water
Add 100ml of Hydrochloric Acid per 40,000 litres of pool water to lower pH by 0.1 point (i.e. 7.9 to 7.8). Run pool pump for at least 1 hour after adding the acid.
