No matter how well built a structure may be, any bricks and mortar used during construction will begin to break apart due to settling and require repairs to prevent water damage and more serious structural issues. Stone pointing in Wilmington, DE is the process used to repair old walls, and although it is a somewhat straightforward process, not using the proper materials and techniques can cause the work to be unsuccessful in providing protection. Here is a quick look at the right way to repoint walls.
Mortar Joint Preparation
While it may seem counterintuitive, the first step is to remove the existing mortar from the joints, so there is a minimum of a three-inch gap. Even areas that are only showing one-inch depth should be dug out further to ensure proper application of the mortar and a bond that will protect from the elements. Remove any debris from the mortar joints to make sure the mortar application can successfully bond to the existing brick.
First Mortar Application
Once the bricks are prepared, the next step is to apply the mortar. Be sure to use a mixture that is a combination of seven parts sand, one part lime, and one part concrete, and then apply it at a depth of 1 1/2 to two inches. Many homeowners are nervous during this step, as this type of mortar is not visually appealing, but it will later be covered with a finishing mortar that will provide the clean appearance most property owners seek.
Finishing Mortar And Shaping
Once the first mortar application is dry, the next step is to fill in the remainder of the joint with a finishing mortar. While it is still pliable, be sure to use a trowel to shape the mortar to give the final product a clean and finished look. Let the mortar dry for a minimum of 48 hours before attempting to clean the repaired area or subjecting it to any moisture.
