Veneer Mortar joints are an important part of any home’s structure and stability. Over time, though, these Mortar Joints can become worn down and even start to crumble. This not only weakens the support your home needs but also makes it look shabby and unkempt. Tuckpointing is a process of repairing Mortar Joints so that they’re once again strong and visually appealing.
Mortar is a mixture that helps masonry units stick together. Mortar joints are the spaces between bricks, stones, or cinder blocks. Mortar can be made from a variety of materials, but it is most commonly made from Portland cement, water, and sand. Mortar joints can be either flush or recessed.
Flush mortar joints are when the mortar is level with the face of the brick. This type of joint is best for protection against weather and forces acting on the wall from the outside. Recessed mortar joints are when the mortar is set back from the face of the brick. This type of joint allows for expansion and contraction of the masonry units caused by changes in temperature.
Grout is a mix of Portland cement and some other sand. Grout is used to fill the spaces between masonry units. It is also a part of the mortar mix. The main function of grout is to provide support and reinforcement to masonry construction. It also acts as a waterproofing agent.
Portland cement is the main ingredient in the grout. Other ingredients include water, sand, and sometimes lime. The ratio of these ingredients varies depending on the type of grout being mixed.
Grout can be mixed by hand or with a mixer. The amount of water added to the mix should be just enough to make the mix workable. Too much water will make the grout weak and susceptible to cracking.
