What Is Weather Struck Pointing?
Weather-struck pointing is a technique used in brickwork to create a slope from the underside of one brick to the face of the one underneath it.
This allows the water to drain away rather than collect on top of any brick, thus preventing damage to the mortar or bricks from damp conditions.
This technique provides better protection against weathering and can help extend the useful life of walls and other structures made with bricks.
What Is The Best Mix For Weather Struck Pointing?
The best mix for repairing weather-struck pointing is one that comprises 1 part Portland cement, 1 part lime, and 5½ parts sand.
This mix provides a strong and long-lasting repointing material that is suitable for use in areas subjected to normal weather conditions.
The combination of these three ingredients forms an ideal mortar mix that offers the perfect balance between flexibility, durability, and quality.
Furthermore, the lime in the mix helps to reduce shrinkage due to changes in temperature or humidity while also allowing the extra absorption of any water present – making it an ideal choice for exterior applications that are exposed to a variety of elements.
What Is Weather Struck Pointing Trowel?
A weather-struck joint is a trowel or jointer profile commonly used in 19th-century civil engineering work.
This joint is formed by compressing the top portion of the joint more than the lower, causing an incline to the blade of the trowel or jointer when finishing off the joint in one continuous stroke.
Weather-struck joints provide excellent strength and durability to masonry works and are still frequently used today thanks to their enduring qualities.
What Is Weather-Struck Stone Pointing?
Weather-struck stone pointing is a process of systematically restoring the integrity and appearance of traditional stonework. It begins with pressing mortar into raked joints, followed by smoothing the mortar to create an even surface along the pointed lines.
The bottom edge is then trimmed with a straight edge and sharp knife for neatness. This method of repair provides a weather-proof seal and adds an attractive finish to stone walls, making it an effective way to restore old buildings or add aesthetic appeal to new structures.
What Kind Of Lime Do You Use For Pointing?
Hydraulic lime mortar is the best kind of lime to use for pointing since it is exceptionally strong, durable, and frost resistant.
Not only does it provide superior protection against the elements, but also it won’t crack or erode over time like other types of mortar – which makes it particularly trustworthy for large structures and those of high architectural value.
It is especially suited to areas where the temperature tends to dip below freezing as its frost resistance helps prevent water from seeping through the walls, causing structural damage.
Additionally, hydraulic lime mortar has a low permeability when placed between layers ensuring that any water ingress is kept to a minimum.
What Are The Weather-Struck Pointing Benefits?
Weather-struck pointing offers many benefits, as it is designed to provide excellent resistance to various types of weather conditions. This type of pointing is completed by first creating a straight joint along the bottom edge, which is then neatly trimmed with a straight edge and a sharp knife.
The joint is finished by sloping from the top of the joint to its bottom, thus creating an additional layer between the masonry and moisture infiltration.
Furthermore, this type of pointing ensures that masonry joints will remain watertight even in cold climates where freezing may occur.
Additionally, weather-struck pointing can also help protect bricks and stones from discoloration due to exposure to rain or sun as well as protect against salt damage caused by coastal environments.
