Home Improvement--General/grout mistake
I forgot to wipe out a very long line of grout when re grouting in the backyard. It got really hard...
Is there any good way of removing this hard grout from the slates?
Thank you very much, Gabe
Absolutely. Get some muratic acid (Home Depot) and dilute it to 30% acid 70% water. Use gloves and pour a little on the oops. Let is sit a min or so and then with a wire brush and putty knife start working the mistake. It will begin to loosen and after a few applications will be gone!
