I have a brick sidewalk that was installed 12-14 years ago with a dry cement/sand mix that was then wetted down. A number of joints have deteriorated, perhaps aided by moss growing in them, and they are in need of repair before the winter. I would like to repair the joints that have developed holes but I do not know the ins and outs of masonry. My thought is to pressure wash the joints, then purchase some mortar mix (Spec Mix has been recommended). I will fill the holes, then level the mortar with a trowel (which type? a thin rectangular one?). It is my understanding that to remove the white mortar that is left that I use acid. What kind and at what strength? How long do I leave it on? Do I wash the whole sidewalk (bricks and mortar) or just the bricks, attempting to keep the acid off of the mortar? How long do I allow the mortar to dry before I do an acid wash? If there is a website that might be helpful, I would be grateful. Thanks Ken K

I'm looking for a brick sealer product to use in Saint Louis. Anyone had experience in that area? What have you found to work best?
