Last week I had my front steps repointed where the old mortar had worn away.They are about 20 years old. The new mortar is so much lighter in color than the old.I was hoping the mason would mix a mortar to match the old stuff, but he didn't and now I am thinking about what I can do to match the new almost white mortar to the old grey/brown weathered mortar.Here are some of the ideas I have come up with.Bear in mind...I know nothing about mortar and how it reacts to different compounds or chemicals after it's set. I thought about trying to clean the old mortar with bleach to lighten it up a bit closer to the new mortar..would scrubing it with a toothbrush be ok.Would bleach be ok to use on old mortar? What about Vinegar?..then I thought about just trying to darken the new mortar , which is a much smaller job..but what should I use..I was thinking of using a small paint brush and mixing a paste of water and cigarette ashes..or maybe ashes from insense...and brushing it over the newer mortar.What about coffee grounds...magic marker? paint of some kind?. some kind of stain?...I am open to suggestion...please E mail me with any you have. thanks
