- House painter and decorator
A house painter and decorator is a tradesman responsible for the painting and decorating of buildings, and is also known as a decorator or house painter. The purpose of painting is to make the house look better or to protect it from damage by water, rust, corrosion, insects or mould.
History of the trade
In England, little is known of the trade and its structures before the late 13th century, at which point guilds began to form, amongst them the Painters Company and the Stainers Company. These two guilds eventually merged with the consent of the Lord Mayor of the City of London in 1502, forming the Worshipful Company of Painter-Stainers. The guild standardised the craft and acted as a protector of the trade secrets. In 1599, the guild asked Parliament for protection, which was eventually granted in a bill of 1606, which granted the trade protection from outside competition such as plasterers.
The Act legislated for a sevens year apprenticeship, and also barred plasterers from painting, unless apprenticed to a painter, with the penalty for such painting being a fine of £5. The Act also enshrined a maximum daily fee of 16 old pence for their labour.
Enforcement of this Act by the Painter-Stainers Company was sought up until the early 19th century, with master painters gathering irregularly to decide the fees that a journeyman could charge, and also instigating an early version of a job centre in 1769, advertising in the London newspapers a "house of call" system to advertise for journeymen and also for journeymen to advertise for work. The guild's power in setting the fee a journeyman could charge was eventually overturned by law in 1827, and the period after this saw the guild's power diminish, along with that of the other guilds; the guilds were superseded by trade unions, with the Operative United Painters' Union forming sometime around 1831.
In 1894, a national association formed, recreating itself in 1918 as the National Federation of Master Painters and Decorators of England and Wales, then changing its name once again to the British Decorators Association before merging, in 2002, with the Painting & Decorating Federation to form the Painting & Decorating Association. The Construction Industry Joint Council, a body formed of both unions and business organizations, today has responsibility for the setting of pay levels.
Tools of the trade
The modern composition of paints results in latex formulations being widely used for exterior as well as interior. That reduces post painting cleanup, and reduces the smells associated with petroleum and polyester based paints. Computerized paint scanners formulate new paints to match the often faded colour of existing paints. Many chain stores offer colour matching service.
Modern paints are available in various specialized formulations that can be fade resistant, chip resistant, odor free, antibiotic to resist mould and fungi growth, etc.
For surfaces where a very smooth surface is desired, most retailers carry inexpensive chemicals that can be added to paints to better make the paint flow or lay flat. Such additives are preferable to thinning paint, which can change some of the paint's characteristics.
For the layman, the most confusing element is primer and priming surfaces. For surfaces such as wood, paint alone is too thick and will be on the surface, but not adhere well, resulting in flaking. Primer is a thin paint solution, or even a specialized liquid colour coordinated to support the finish coat, which penetrates into the pores of wood, and allows the finish coat to adhere to the underlying primer.
Priming also results in less paint being needed. For unpainted wood, most laymen expect to apply two coats of paint. However, one coat of inexpensive primer and then a finish coat is much less expensive.
For metal surfaces, primer may involve special characteristics to resist corrosion, prevent impact chipping or improve adhesion of the finish coat.
Especially for problem paint jobs, such as new work, fungal presence or peeling paint, most professional paint retailers offer free consulting services. When their instructions and materials are used, guarantees of 5 to 20 years are available as to adhesion, water proofing, etc. of the finished paint job.
For professional painters, the majority of their time is spent in preparation for paint application, not in painting per se. Cleaning and sanding surfaces, taping and applying paper or plastic to surfaces not to be painted typically involve 50% or more of the painter's total time budget.
Although the brush and the fabric roller were the tools most readily associated with the painter, foam brushes are now commonly used for precise work requiring a straight line. Foam brushes can also be used to create a smoother surface using less paint that dries more quickly than brush applications. Like fabric rollers, foam rollers can also create patterns in the painted surface. Foam rollers are available in a variety of professional materials for high-quality applications.  Although used in a variety of applications, the foam roller is commonly used during the painting of doors to produce an extremely smooth finish.
Recent advances in manufacture have led to a standardization of brushes, with many older types of brushes falling from fashion. The spray gun is one of the latest tools in the painter's arsenal. It is powered by an electric, pneumatic or fuel powered motor which pumps paint through a hose into a gun which atomizes the paint to a fine spray. With the airless spray gun it is possible to paint extremely large areas of surface in a short time.
However, sprayed paint when dry can display unsightly patterns if the spraying application does not result in an even distribution of paint.
The ground brush, also known as a pound brush, was a round or elliptical brush bound by wire, cord or metal. They were generally heavy to use, and required considerable usage to break them in. These brushes were predominantly used in the days before modern paint manufacturing techniques; hand-mixed paints requiring more working to create the finish. These brushes still have use in applying primer, as they are useful in working the primer into the grain of the wood. Pound brushes required an even breaking in to create even bevel on both sides of the brush, minimising the formation of a point which would render the brush useless. Sash tools were smaller brushes, similar to a ground brush, and used mainly for cutting in sash or glazing bars found on windows.
Sash tools and ground brushes generally required bridling before use, and a painter's efficiency in this skill was generally used as a guide to their overall ability. Both these brushes have largely been superseded by the modern varnish brush. Varnish brushes are the most common flat brushes available today and are used for painting as well as varnishing. Brushes intended for varnishing typically have a bevelled edge.
Distemper brushes, used for applying distemper, an early form of whitewash, were best made of pure bristle and bound by copper bands to prevent rust damage. Styles differed across the world, with flat nailed brushes popular in Northern England, a two knot brush (a brush with two ovular heads) popular in Southern England, and three knot brushes or flat head brushes preferred elsewhere. In the United States distemper brushes were known as calcimine, kalsomine or calsomine brushes, each term being the U.S. variant of whitewash.
Fitches are smaller brushes, either ovular or flat and one inch wide, that are used in fine work such as to pick out the detail on a painted moulding. Stipplers come in various shapes and sizes and are used to apply paint with a stippled effect. A duster or jamb brush was used to dust the area to be painted before work commenced. Stencil brushes, similar in style to a shaving brush, were used for the purpose of stencilling walls or in the creation of hand-made wallpapers.
Brushes are best stored in a purpose made brush keeper, a box on which a wire could be suspended. The wire would be threaded through the hole in a brush's handle so as to suspend the brush in a cleaning solution without allowing the brush to sit on the bottom of the container and thus cause spreading of the bristles. The solution would also prevent hardening of the brushes and oxidization. These were generally rectangular and stored several brushes. A lid would enclose the brushes and keep them free from dust.
If brushes are cleaned after use, they can last for years. Since most modern exterior and interior paints are latex based, cleaning the brushes after use with hot soapy water and a toothbrush can remove all traces of paint. Oil based paints are normally cleaned with a petroleum solvent such as mineral spirits, again using a toothbrush to remove all traces of paint. Metal "combs" are used to penetrate into the bristles of a brush to remove drying paint.
Although paints are now available in no-drip containers to pour paint into trays for roller application, most paints are sold in metal gallon or quart cans. For large jobs, paints come in 5-gallon containers.
For metal cans, a large diameter nail or punch is used to make drain holes in the lip of the can. The holes allow paint to return into the can. The lid can then be reattached correctly and removed later. Without the drain holes paint will accumulate in the lip, and act as an adhesive preventing the lid from being easily removed later. Closing a lid with paint in the lip can also result in paint travelling 15-feet or more horizontally.
The air in partly filled paint cans forms over time a dried surface film. To prevent development of film, prior to closing a latex paint container add a small amount of distilled (or tap) water that will remain on the top and prevent drying. For oil based paints use the solvent recommended for brush cleaning. When the container is reopened, stir the water/solvent into the paint before using.
Drop cloths, brown painter's paper, dust-sheets, paint sheets, paint tarpaulins or plastic protection films are used to protect nearby surfaces that are not being painted.
Masking tape can be used to define the line between the painted and unpainted surface, as well as to hold protection materials in place. Masking tape is available in several categories. The classic tape is a high adhesive. However it can damage the underlying surface when removed, and the longer it's in place the greater the risk of damage.
Modern delay removal tape prevents damaging the taped surface. "Delicate" tape has about 40% the adhesion of traditional tape, and can remain on a surface for up to 30-days without creating damage.
The less adhesive tapes should be used especially when tape is applied to new work. Depending on the paint composition, "dry" paint may still be soft and easily damaged for 30-days or more.
Some modern house painters in the US, Canada and Australia have adopted colour visualization computer software, developed by companies such as Autech Software & Design, as an additional tool to help demonstrate to customers how their home would look after it is painted. House painters can use a digital photo outputted by this software to show possible colour schemes on the client's home exterior or room walls to help with their colour selection.
Activities of the trade
Historically, the painter was responsible for the mixing of the paint; keeping a ready supply of pigments, oils, thinners and driers. The painter would use his experience to determine a suitable mixture depending on the nature of the job. In modern times, the painter is primarily responsible for preparation of the surface to be painted, such as patching holes in drywall, using masking tape and other protection on surfaces not to be painted, applying the paint and then cleaning up.
Larger firms operating within the trade were generally capable of performing many painting or decoration services, from sign writing, to the gilding of objects or the finishing or refinishing of furniture.
More recently, professional painters are responsible for all preparation prior to painting. All scraping, sanding, wallpaper removal, caulking, drywall or wood repair, patching, stain removal, filling nail holes or any defects with plaster or putty, cleaning, taping, preparation and priming are considered to be done by the professional contracted painter.
Before repainting, surfaces are usually cleaned with sugar soap (in Commonwealth countries) which usually contains sodium carbonate, sodium phosphate, and sometimes sodium silicate as an abrasive, though formulations vary. In the U.S.A. a similar compound known as TSP is used but some modern formulations do not contain phosphates due to environmental concerns.
Professional painters need to have keen knowledge of tools of the trade, including sanders, scrapers, paint sprayers, brushes, paint rollers, ladders and scaffolding, in addition to just the paint in order to correctly complete work. Much preparation needs to be considered before simply applying paint. For instance, taping and dropcloth techniques, sizes of brushes or rollers, material types or dimensions of rollers or brushes (there are different sizes or types of brushes and rollers for different paints), amount of paint, number of paint coats, amount of primer, types of primers and paints, certain grits and cuts of sandpaper, trim cutting (the act of painting with a brush on the outline of baseboard, mouldings and other trim work), wallpaper removal, and nail-hole filling techniques. Today many painters are attempting to break into the field of faux painting, allowing them more creativity and access to a higher end customer base.
