Hydrochloric Acid is a highly corrosive liquid with several uses, including concrete etching, brick cleaning and pH stabilising.
When used in conjunction with relevant usage instructions, Hydrochloric Acid can be used to clean and etch concrete surfaces prior to sealing.
- Non toxic, non corrosive, non hazardous and non flammable
- Pleasant odour, rapid dissolving action
- Eco and user friendly
- Safe, 100% biodegradable, ready for dispersal
Always pre-wet the surface before use as it will affect the performance of the acid. Dilute 1 part Hydrochloric Acid to 12 parts water. (Always add acid to water, never water to acid).
Using a watering can, apply a generous amount to the desired area and allow 15 to 25 minutes to penetrate DO NOT ALLOW THE SURFACE TO DRY.
Pressure wash off, heavily affected areas may require another application and the use of a stiff bristle broom.
Do NOT apply in hot weather, as it is more effective in cooler temperatures during morning or evening hours or in shaded areas.
