How Did Bricklayers Lay Butter Joints in Traditional Construction Methods?

Bricklayers skillfully employed the technique of laying butter joints, a method that involved the precise application of mortar onto the face of the brick with the intention of creating a distinctive look. These butter jointed face bricks were often poorly pointed using a robust mortar mixture infused with a higher concentration of white Portland cement. Originally, the bricks were adorned with black mortar, while the joints boasted a flush joint appearance. Through this meticulous process, the mortar was delicately smeared onto the brick's surface, resulting in joints that appeared thicker than their actual dimensions.

What Is Buttering in Masonry?

To achieve a successful buttering, the mason must ensure that an adequate amount of mortar is evenly distributed on the end of the brick. This helps to create a strong bond between the brick and the mortar, enhancing the overall stability and durability of the structure. The process requires precision and skill, as too much or too little mortar can result in an uneven surface or weak joints.

Next, the loaded trowel is held at a slight angle, allowing the mortar to evenly spread and adhere to the end of the brick. By gently pressing the brick into the mortar, the mason ensures that the entire end is covered in a thin, consistent layer. This not only provides an aesthetic appeal but also prevents moisture penetration, which can cause structural damage over time.

After buttering the brick, it’s carefully placed into the established row, aligning it with the surrounding bricks. The brick is gently pressed into place, ensuring a solid connection with the mortar joints. The mason must also ensure that the bricks are level and plumb, using a level and masons line as necessary.

In addition to cleaning the bricks and avoiding the premature drying of mortar, wetting bricks also ensures better adhesion between the bricks and mortar, resulting in a stronger bond and overall stability of the structure. This simple yet important practice is a crucial step in the bricklaying process, providing long-lasting and durable constructions.

Why Do Bricklayers Wet Bricks?

Bricklayers often wet bricks to aid in the cleaning process. Bricks are often subjected to adverse conditions, such as storage in open areas, which can cause dirt, sand, and dust to accumulate on their surfaces.

In addition to cleanliness, wetting bricks also helps in preventing the suction of water from wet mortar. Mortar is a mixture of cement, sand, and water, used to bind bricks together. This can result in compromised structural integrity, as the mortar may crumble and fail to provide adequate strength.

This ensures that the mortar creates a strong bond between the bricks, enhancing the overall strength and stability of the structure.

This enables bricklayers to lay bricks with greater precision and accuracy, achieving a more uniform and structurally sound finish.

These benefits contribute to the construction of stronger, more durable brick structures.

Different Methods of Cleaning Bricks: Besides Wetting, What Other Methods Can Be Used to Clean Bricks and Remove Dirt, Sand, and Dust From Their Surfaces?

  • Using a stiff-bristle brush to scrub the dirt and dust off the surface
  • Blasting the bricks with high-pressure water to remove dirt particles
  • Applying a brick cleaning solution and scrubbing with a sponge or scrub brush
  • Using a power washer to remove stubborn stains and dirt
  • Sandblasting the bricks to effectively remove all accumulated dirt and grime
  • Chemical cleaning methods, such as using muriatic acid diluted with water


The intricacy and precision of this method required skill and expertise from the bricklayers, highlighting their craftsmanship and ability to manipulate materials to achieve desired visual effects.
