I am about to retuckpoint my exposed brick wall with a custom mortar mix (1x hydraulic lime, 2.5x sand). Once I am done, I plan to clean the residue and other dirt from the bricks using muriatic acid.
My question is: what is the minimum amount of time I should wait for the mortar to cure before it is safe to apply muriatic acid over it? Is a couple of days enough? I have heard that masonry mixes (concrete/mortar) take as long as two weeks to fully cure, I was unsure whether it is safe to bring it in touch with a substance as potent as muriatic acid during that time frame.
