The first recorded paintbrushes date back to 1330 A.D. during the times of the Phoenicians.
For centuries, paintbrushes remained round in shape. Even today, many European-made paintbrushes are round.
Here in North America, the majority of paintbrushes are flat in shape
MAJOR COMPONENTS OF A PAINTBRUSH
1) Handle - Can be made from wood, plastic or foam injection. Uniquely designed, the handle provides comfort and good balance. There are two ways to attach the handle to the ferrule; by nailing or crimping them.
- The metal band that holds the filament and the handle together is called
a ferrule. The ferrule can be made of bright tin, nickel, stainless steel,
copper or brass plated.
Wood is the traditional standard for professional handles. Many contractors have preferred the balance, weight and feel of wooden handles.
The D.I.Y. quality of paintbrush handles are typically made of plastic or injected foam. The shape and style are dependant upon the intended job use.
- Thin long handles in regular or rat-tail shape provide extra control for use
on narrow areas.
Varnish - Pencil shape handles are designed for a comfortable feel when applying coatings on small to medium areas.
Wall - Large, thick handles allow a good, firm grip for painting large areas.
Various materials such as stainless steel. nickel, brass or tin are common alloys used. The importance of the material used is to assure rust and corrosion resistance.
Bristle : Natural pig or hog bristle is the most popular material used in paintbrush manufacturing. These bristles predominantly come from China. Bristles vary in length, stiffness and thickness. These natural characteristics are difficult to duplicate with synthetic materials.
Like some human hair, bristle has naturally split ends called "flags". Flags are very important. They help to hold paint in the brush so it is released evenly throughout the stroke instead of all at once on the first contact point. Flags also provide an extra-smooth finish with minimal brush marks because there are more "individual paint spreaders".
Nylon : When nylon was first used in the construction of paintbrushes, it was simply tapered filament mixed with horsehair. Over time, the processing of nylon has greatly improved so that now many contractors use nylon brushes. Because it is so durable, nylon is great to use on rough surfaces. Easy clean ability makes it the best material to use with fast-drying paints like acrylics.
Polyester : was introduced to reduce the cost of the synthetic filament. Also, the nature of the material does not allow the filaments to absorb any moisture whatsoever. It therefore maintains consistent stiffness.
Blends : The most popular synthetic paintbrushes combine the best qualities of nylon and polyester together in one brush. Polyester is used in the shorter
|lengths to give the brush resistance to heat and stiffness when used with water based paints; nylon is used in the longer lengths for precise tipping and maximum durability. Blends give outstanding performance in all types of paint, including latex, acrylics, alkyds and oil base.|
The first paint rollers were developed in England. Today, rollers are extremely popular. They are a fast, effective and simple method of applying paint to large areas.
MAJOR COMPONENTS OF A PAINT ROLLER COVER
1) Core - Base of the roller cover; it can be plastic, cardboard or phenolic-impregnated. Plastic cores vary in durability and quality levels, from DIY to professional.
Untreated cardboard cores are usually found in throwaway covers. Phenolic cores provide durability that stand up to many chemical products that are used for special applications.
2) Epoxy - Type of adhesive used to bond the fabric to the core of the roller; it resists solvents and chemicals.
3) Fabric - Part of the cover that carries the paint, consisting of individual fibres woven or knitted to a backing. Better roller covers have high-density fabric with many fibres per square inch as well as fibres of varying diameters, for higher paint capacity.
Roller covers, like brushes, are available in various qualities and can be made with natural or synthetic materials; 96% of all roller covers are synthetic.
Natural Fabric The original, natural roller fabric is shearling wool. Mohair covers contain blended natural and synthetic fibres. They have higher paint capacity than all other roller covers. Still, DIY painters rarely use these covers because they cost much more than synthetic ones.
|Synthetic Fabrics Synthetic roller covers are made with different blends of nylon, polyester, acrylic, rayon and other synthetic materials. In general, they can be used with all types of coatings, from latex to oil-based, but the type of synthetic cover used should be chosen carefully.|
USE ROLLER COVERS
Special use covers are designed for specific needs. Twisted fabric is used to create textured finishes.Polyurethane foam covers leave no lint and minimal air bubbles for glossy enamels. Synthetic, short napped fabrics apply adhesives and epoxies for wall coverings or floor tile. There is a roller cover designed for every type of application.
Many people only consider price when choosing a roller cover. There are many reasons why better-quality rollers are worth more than inexpensive ones.
