How do I color mortar for crack repairs to match a yellowish sand color for 25 year old brick mortar ?

Answer 1

start mixing & slapping it on a test board, write down your mixes... when you get close adjust your mix by small increments (WRITE DOWN EACH MIX - YOU'RE GOING TO WASTE SOME SAND & MORTAR MIX & COLOR - MIX IN INCREMENTS THAT CAN BE REPRODUCED EVEN IF IT'S 2 CUPS AT A TIME), test again against clean old mortar! Have a judging contest on which one matches best!
go to it!

Answer 2

if you can knock out a pice with some size to it, take it to your masonry supplier , they usually have mortar samples...

Answer 3

Answer 4
