Flush Pointing : Edges finished flush with mortar for durability.
Keyed Pointing : Similar to flush pointing, widely employed for longevity.
Recessed Pointing : Mortar pushed back, creating a visually appealing look.
Struck Pointing : Essential for rapid drainage in wet weather, forming a slope.
Beaded Pointing : Grooves created with a concave tool for aesthetic appeal.
Truck Pointing : Mortar applied and cut in the middle of the channel.
V-Grooved Pointing : Forms a V-shaped groove on the finished side.
Weathered Pointing : Mortar pressed into joints and neatly pressed back for a sloping effect.
Joint Sealing : Used with cement mortar to seal joints between bricks.
Stone Masonry Enhancement: Strengthens pointing by incorporating stones.
Crack Maintenance: Repairs and maintains cracks in buildings through repointing.
Aesthetic Enhancement: Used to enhance the visual appeal of structures.
In essence, pointing serves as a vital maintenance practice for buildings, ensuring the longevity and structural integrity of mortar joints in brick or stone masonry. By addressing aging joints, pointing contributes to the sustained health and aesthetic appeal of structures.
