This joint design requires no tooling and is formed naturally as excess mortar is squeezed out from between the bricks. The result is a rustic, textured appearance. This design is not recommended for exterior building walls due to the tendency for exposed mortar to break away, degrading the wall’s appearance. Beaded joint
Mortar is a workable paste which hardens to bind building blocks such as stones, bricks, and concrete masonry units, to fill and seal the irregular gaps between them, spread the weight of them evenly, and sometimes to add decorative colours or patterns to masonry walls.
Mixing mortar is normally done today with mortar mixers which usually use a rotating drum or rotating paddles to mix the mortar. The masonry trowel is used for the application of the mortar between and around the stones as they are set into place. Filling in the gaps (joints) with mortar is referred to as pointing.
Mortar placed horizontally below or top of a brick is called a bed, and mortar placed vertically between bricks is called a perpend. Solid brick Single frogged brick Double frogged brick Cellular brick Perforated brick. A brick made with just rectilinear dimensions is called a solid brick. Bricks might have a depression on both beds or on a ...
German masons repointing a wall in 1948. Repointing is the process of renewing the pointing, which is the external part of mortar joints, in masonry construction. Over time, weathering and decay cause voids in the joints between masonry units, usually in bricks, allowing the undesirable entrance of water.
Brick trowel: or mason's trowel is a point-nosed trowel for spreading mortar on bricks or concrete blocks with a technique called "buttering". The shape of the blade allows for very precise control of mortar placement. Bucket trowel: a wide-bladed tool for scooping mortar from a bucket; it is also good for buttering bricks and smoothing mortar.
Tuckpointing was a way of achieving a similar effect using cheap, unrubbed bricks; these were laid in a mortar of a matching colour (initially red, but later, blue-black bricks and mortar were occasionally used) and a fine fillet of white material, usually pipe clay or putty, pushed into the joints before the mortar set.

Holes in bricks have much more to do with speeding the drying and firing of the bricks, and reducing the mass of the brick, than they have to do with providing sockets into which plugs of mortar can fit. There's a sufficient abundance of friction in a sandwich of bricks and mortar to make holes structurally redundant.
