Hey there, time traveller!
This article was published 28/03/2004 (7856 days ago), so information in it may no longer be current.
QUESTION: Andrew asks: I have an exposed aggregate patio.
The four-foot-square slabs used to be divided by 2×4 redwood. The redwood finally rotted, so I replaced it with concrete. In some places the filler concrete spread over the exposed aggregate. I didn’t get it hosed off in time. I’ve tried wire-brushing with an electric drill, but it isn’t doing the job.
Any advice?
ANSWER: Use tape and polyethylene sheeting to protect what exists. Use a 20 per cent solution of muriatic acid to eradicate the spill. A wire brush will still be needed. Remember, muriatic acid is a diluted form of hydrochloric acid — highly dangerous stuff!
Use eye protection, gloves and protective clothing to do the job. Since concentrated muriatic acid dissolves concrete, you can imagine what it well could do to your eyes and skin.
When the job is done, sprinkle baking soda everywhere the acid was placed, and rinse it into your garden with a water hose.
