Brick Slip Mortar, Meaning, Uses, and Selection
Understanding Brick Slip Mortar
Brick slip mortar is the material used to fill and finish the joints between brick slips once they have been fixed to a wall. Unlike the adhesive used to bond the slips to the surface, brick slip mortar is applied after installation to create the visible joints that replicate traditional brickwork.
It plays a key role in defining the appearance of the finished wall while also contributing to durability, weather resistance, and overall performance of the bricbrick slip system.
Purpose of Brick Slip Mortar
The primary purpose of brick slip mortar is to complete the brickwork effect by forming consistent, well-finished joints between each brick slip. It also helps protect the installation from moisture and environmental exposure, particularly on external walls.
Key functions of brick slip mortar include:
-
Creating realistic mortar joints that define the brick pattern.
-
Sealing gaps between brick slips to reduce water ingress.
-
Improving the overall strength and cohesion of the installation.
-
Allowing colour and joint style to influence the final visual effect.
The choice of mortar has a significant impact on both appearance and longevity.
Types of Brick Slip Mortar
Brick slip mortar is typically available in cement-based or lime-based formulations, with a range of colours and finishes. The correct type depends on the application and desired look.
Common options include:
-
Cement-Based Mortar – Strong and durable, commonly used for external installations.
-
Lime Mortar – More flexible and breathable, often used for heritage-style finishes.
-
Coloured Mortar – Used to complement or contrast with brick slip colours.
-
Pre-Mixed Pointing Mortar – Designed for consistency and ease of use on site.
Selecting the appropriate mortar ensures compatibility with the brick slips and the installation environment.
Applying Brick Slip Mortar
Brick slip mortar is applied once the brick slips have been securely fixed and the adhesive has cured. The mortar is worked into the joints using a pointing gun or trowel, ensuring full joint depth and even coverage.
After application, the mortar is tooled to achieve the desired finish, such as flush, recessed, or bucket handle pointing. Excess mortar is cleaned from the brick faces as it begins to set, leaving a crisp and professional result.
