| I'm trying to rebuild my brick porch wall but I can't seem to get the visible verticle joint to come out right. I can't get enough mortar at the edge of the verticle joint, I always have to come back and fill it in which gets mortar all over the brick. The house is 100 years old and I'm using a lime based mortar with a 1:1:6 ratio of white portland, lime, and sand. The sand if white silica and is commonly used for sand blasting today. Any suggestions would be helpful. |

It should not be that much of a problem.Maybe the mortar is too liquid and runs out. If you have to fill the vertical joint with additional mortar and it gets on the face of the brick,wipe the stained part off with a wet sponge. The excess on top of the brick will be receiving more mortar to lay the one above it. Am I missing your point here? Don't mind the pipe layers above.They are stuck in time, in their respective High Schools [:D] |

I actually studied masonry in high school back when they actually taught STUFF (33 years ago) Its one of those things I can do but cant quite figure out how to explain. Its one of those things you just have to feel out. You have to use too much and then clean the joint up after the brick is in place. Dont worry about excess getting on the brick. like Ed said the wet sponge is good and anything that survives that can be removed later by several different methods. |

Well then try more Portland,you have old brick,and will just have to try the right recipe that gives you the the right mixture for your job! The old brick(100 years old) is probably fired or made different than any new brick(probably less pursed more dense than new brick) Bob [:D] |
