Tuckpointing (also called tuck pointing or tuck-pointing) is a way of using two contrasting colours of mortar in the mortar joints of brickwork, with one colour matching the bricks themselves to give an artificial impression that very fine joints have been made. In some parts of the United States and Canada, some confusion may result as the term is often used interchangeably with pointing (to correct defects or finish off joints in newly laid masonry) and repointing (to place wet mortar into cut or raked joints to repair weathered joints in old masonry).
The tuckpointing method was developed in England in the late eighteenth century [1] to imitate brickwork constructed using rubbed bricks (also rubbers and gauged bricks), which were bricks of fine, red finish that were made slightly oversized, and after firing, were individually abraded or cut, often by hand, to a precise size. [2] [3] When laid with white lime mortar, a neat finish of red brick contrasting with very fine white joints was obtained. 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. [4] The term tuckpointing derives from an earlier, less sophisticated technique that was used with very uneven bricks: a thin line, called a tuck , was drawn in the flush-faced mortar, but left unfilled, to give the impression of well-formed brickwork.[ citation needed ] "Wigging", an Irish technique similar in effect, reverses the order. The white ribbons are applied first, and the surrounding mortar filled or colored to match. [5]
Professional tuckpointers use tools, which, depending on the country and local trade terminology, are sometimes termed "jointers", "tuck irons" [1] or "tuckpointing irons"; primarily in London where the trade originated.[ citation needed ]
Tuckpointing tools were originally made from wrought iron by blacksmiths in England during the 18th century.[ citation needed ] Modern tuckpointing tools are constructed from hardened tool steel, and typically have a wooden or synthetic handle that is attached to the tool surface by a metal ferrule. The tool surface has a sharply pointed front and a flat, beaded or grooved base; the sharp point aids the user in smoothing the tuckpointed line. This is similar in principle to the pointed floats used by concrete finishers to smooth out a surface.[ citation needed ]
The thickness and width of a tuckpointing tool common ranges from 1 millimetre (0.039 in) to 14 millimetres (0.55 in). The thickness and width of these tools are dependent upon the mason's preference and the type of brick or stonework they are tuckpointing.[ citation needed ] Wider tools are often used when tuckpointing stonework.[ citation needed ]
There are many types of tuckpointing tools. Standard and flat-bottomed tools were once the most-commonly used tuckpointing tools, primarily because they could be easily manufactured by early blacksmiths. Standard tuckpointing tools are versatile and can be used for a variety of jobs.[ citation needed ]
Tuckpointing tools are sometimes "beaded"; these tools were crude instruments made by blacksmiths by hitting a rounded leading-edged hammer against a red-hot tuckpointing iron. This process has since been refined and now a small fillet is ground into the flat of the tuckpointing tool that comes into contact with the perps (gaps between the bricks in which mortar runs vertically perpendicular to the ends) or gaps in the brickwork. [6] "Lines" run in the horizontal direction.
The lengths of tools varies based upon personal preferences, but the most common lengths are between 7.5 centimetres (3.0 in) and 12.5 centimetres (4.9 in). Masons and bricklayers sometimes need shorter or longer tuckpointing tools. Shorter tools help the worker access hard-to-reach spots; these tools are referred to as "stubnose" tools, while their longer counterparts are known as "longnose" tools. They are available in many beaded or grooved profiles.[ citation needed ]
Rounded corner tuckpointing tools are curved; instead of a flat bottom, the tool has a curved bottom surface that helps in applying lime putty to rounded bricks. The process of tuckpointing requires that the excess lime putty is cut away from the fine tuckpointed line. This is performed using a Frenchmen [1] knife, a type of knife with a small, sharp, bent tip that allows the lime putty to be cut when guided along the tuckpointed line with a tuckpointer's straight edge. A double Frenchmen knife works by cutting both top and bottom tuckpointed fine lines in one pass, making the process quicker. Double Frenchmen knives can be adjusted to match the width of the fine tuckpointed lines.[ citation needed ]
Many historic homes with classic Italianate architecture are examples of recent tuckpointing, such as Werribee Park Mansion at Werribee Park in Victoria, Australia, which displays the contrast between the tuckpointed white lines in the mortar between its bluestone architecture.[ citation needed ]
A brick is a type of construction material used to build walls, pavements and other elements in masonry construction. Properly, the term brick denotes a unit primarily composed of clay, but is now also used informally to denote units made of other materials or other chemically cured construction blocks. Bricks can be joined using mortar, adhesives or by interlocking. Bricks are usually produced at brickworks in numerous classes, types, materials, and sizes which vary with region, and are produced in bulk quantities.
A chisel is a wedged hand tool with a characteristically shaped cutting edge on the end of its blade, for carving or cutting a hard material. The tool can be used by hand, struck with a mallet, or applied with mechanical power. The handle and blade of some types of chisel are made of metal or wood with a sharp edge in it.
Stonemasonry or stonecraft is the creation of buildings, structures, and sculpture using stone as the primary material. Stonemasonry is the craft of shaping and arranging stones, often together with mortar and even the ancient lime mortar, to wall or cover formed structures.
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. In its broadest sense, mortar includes pitch, asphalt, and soft mud or clay, as those used between mud bricks, as well as cement mortar. The word "mortar" comes from Old French mortier, "builder's mortar, plaster; bowl for mixing." (13c.).
Plaster is a building material used for the protective or decorative coating of walls and ceilings and for moulding and casting decorative elements. In English, "plaster" usually means a material used for the interiors of buildings, while "render" commonly refers to external applications. The term stucco refers to plasterwork that is worked in some way to produce relief decoration, rather than flat surfaces.
Brickwork is masonry produced by a bricklayer, using bricks and mortar. Typically, rows of bricks called courses are laid on top of one another to build up a structure such as a brick wall.
A file is a tool used to remove fine amounts of material from a workpiece. It is common in woodworking, metalworking, and other similar trade and hobby tasks. Most are hand tools, made of a case hardened steel bar of rectangular, square, triangular, or round cross-section, with one or more surfaces cut with sharp, generally parallel teeth. A narrow, pointed tang is common at one end, to which a handle may be fitted.
A trowel is a small hand tool used for digging, applying, smoothing, or moving small amounts of viscous or particulate material. Common varieties include the masonry trowel, garden trowel, and float trowel.
Moulding, or molding, also coving, is a strip of material with various profiles used to cover transitions between surfaces or for decoration. It is traditionally made from solid milled wood or plaster, but may be of plastic or reformed wood. In classical architecture and sculpture, the moulding is often carved in marble or other stones. In historic architecture, and some expensive modern buildings, it may be formed in place with plaster.
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. Water entering through these voids can cause significant damage through frost weathering and from salt dissolution and deposition. Repointing is also called pointing, or pointing up, although these terms more properly refer to the finishing step in new construction.
Strapping, also known as bundling and banding, is the process of applying a strap to an item to combine, stabilize, hold, reinforce, or fasten it. A strap may also be referred to as strapping. Strapping is most commonly used in the packaging industry.
London stock brick is the type of handmade brick which was used for the majority of building work in London and South East England until the increase in the use of Flettons and other machine-made bricks in the early 20th century. Its distinctive yellow colour is due to the addition of chalk. Another important admixture is 'spanish', which is made up of ash and cinders from incinerated waste and rubbish. The spanish ignites on firing and reduces fuel costs at the firing stage. London Stocks are still made in comparatively small quantities in traditional brickworks, mainly in Kent and Sussex, for heritage work, and machine-made versions are available for use where a cheaper approximation to the traditional product is acceptable. Red stock bricks are also fairly common, but only the yellow or brown bricks are usually known as London stocks.
Plasterwork is construction or ornamentation done with plaster, such as a layer of plaster on an interior or exterior wall structure, or plaster decorative moldings on ceilings or walls. This is also sometimes called pargeting. The process of creating plasterwork, called plastering or rendering, has been used in building construction for centuries. For the art history of three-dimensional plaster, see stucco.
A putty knife is a specialized tool used when glazing single glazed windows, to work putty around the edges of each pane of glass. An experienced glazer will apply the putty by hand, and then smooth it with the knife. Modern insulated glazing may use other ways of securing the glass to the window frame.
A plasterer is a tradesman or tradesperson who works with plaster, such as forming a layer of plaster on an interior wall or plaster decorative moldings on ceilings or walls. The process of creating plasterwork, called plastering, has been used in building construction for centuries. A plasterer is someone who does a full 4 or 2 years apprenticeship to be fully qualified.
Lime mortar or torching is a masonry mortar composed of lime and an aggregate such as sand, mixed with water. It is one of the oldest known types of mortar, used in ancient Rome and Greece, when it largely replaced the clay and gypsum mortars common to ancient Egyptian construction.
The Masonry trowel is a hand trowel used in brickwork or stonework for levelling, spreading and shaping mortar or concrete. They come in several shapes and sizes depending on the task. The following is a list of the more common masonry trowels:
Opus spicatum, literally "spiked work," is a type of masonry construction used in Roman and medieval times. It consists of bricks, tiles or cut stone laid in a herringbone pattern.
A kitchen scraper is a kitchen implement made of metal, plastics, wood, rubber or silicone rubber. In practice, one type of scraper is often interchanged with another or with a spatula for some of the various uses.
In masonry, mortar joints are the spaces between bricks, concrete blocks, or glass blocks, that are filled with mortar or grout. If the surface of the masonry remains unplastered, the joints contribute significantly to the appearance of the masonry. Mortar joints can be made in a series of different fashions, but the most common ones are raked, grapevine, extruded, concave, V, struck, flush, weathered and beaded.
