How to choose the right raw material of paint brush bristle?

Shape

If you are looking for more details, kindly visit our website.

There are many types and shapes of brushes, and the shapes of commonly used artist brushes are&#;

Round brush:

One of the oldest oil paint brushes. It has a blunt tip for a rounder, softer strokes;

The small round oil brush can be used for outlining, and the side edge can be used for large blurred halos, and can also be used for stippling techniques.

Flat brush:

Flat-bodied flat-head oil paint brushes did not appear until the 19th century.

Use to create broad, sweeping strokes; use the side of the flat head for rougher lines; turn the pen body for sweeping strokes for uneven strokes.

Hazel Brush:

Flat body and round head, also known as "cat tongue pen".

It has the characteristics of both round and flat brushes, but it is difficult to control. It is a more elegant and fluid brush for expressing curved strokes.

Fan brush&#;

It belongs to a new special oil paint brush, with sparse brush hairs and a flat fan shape.

Use for swipe and brush in wet painting, or to soften overly sharp outlines.

Painters who prefer a thin technique often use this brush. When rubbing color with a fan-shaped pen, it must be kept clean, otherwise, it will hinder its dexterity.

First, and foremost, the better the quality of applicator tool - the easier the painting and the better the results. A quality brush will hold more paint, control dripping and spattering and apply paint more smoothly with minimal brush marks. A quality brush will give a long even release of paint, and the advantage, especially to a professional painter, of cut-ability (the ability to quickly and precisely strike a straight edge). Above all, a quality brush has durability which is measured in terms of bristle or filament shape and retention. Lesser quality brushes tend to lose filament shape quickly and lose filaments sooner.

Types of Filaments (Bristles):

Synthetic brushes can be used with all paints but are especially recommended for use with waterborne coatings (latex, acrylic). They perform well while painting smooth to rough surfaces and in hot or humid conditions. 

Natural bristled brushes are best used with oil-based paints, shellacs, varnishes, alkyd enamels, oil-based stains and polyurethanes. They are NOT recommended for latex/acrylic/waterborne paints because they will absorb water causing the bristle to become too soft for effective painting. Also, rough surfaces will damage the bristles on a naturally bristled brush. Synthetics last about 5 times longer on average. 

The most important part of the paintbrush is the working end. Performance is based on the engineering of the filament, which is invisible to the naked eye. The filament and how it is finished, or tipped, affects the feel of the brush and the finish the brush leaves. Quality synthetic brushes will have Tapered filaments. This helps paint flow for better coverage. They &#;pump the paint&#; out and down to the surface. It also gives shape to the brush for precise cutting in. If the brush is thick at the base but gets thinner as it comes to the point, then the brush is tapered. An un-tapered brush is thick from base to tip. A tapered brush will outperform an un-tapered brush. 

Types of Synthetic Brushes:

Nylon:  Softer synthetic filament. Very durable. Tips very precisely for a smooth finish. Lasts longer but will soften in hot weather or prolonged use.

Chinex:  Maintains stiffness for control. Resists heat/humidity.  Last 7 times longer than a natural bristle. Perfect balance of paint pick and release. Cleans easily.

Nylon/Polyester:  Combines the positive qualities of nylon and polyester filaments. Polyester used in short lengths to add stiffness and control. Nylon used in long lengths for precise tipping and smooth finish. Takes some time to clean. 

Polyester:  Does not absorb water, resists heat and softening. Does not last as long. Can&#;t be precisely tipped and tends to leave brush marks. Difficult to clean.

Types of Natural Brushes:

Black China Bristle: Stiffer natural bristled brush, excellent for high productivity. Perfect for alkyd enamels, varnish, brushing-lacquers, paints, and other coatings.

White China Bristle: Slightly thinner and softer than the black China bristle. Recommended for solvent-based stains, varnishes, marine coatings, and urethanes.

Degrees of Filament Stiffness

Many factors determine the type of brush that will provide the best results for the job-the paint being used, the environmental conditions, the surface itself, and user preference. Today&#;s manufacturers are making brushes in various blends, so the user can choose the feel they like the most.

Soft: Great for fine finish painting and interiors. Works best in low humidity and cooler temperatures. Extra flex and smoothness. Recommended for use with clears, stains, lightweight paints, fast-drying coatings.

Firm:  Designed for all-purpose interior/exterior painting. Just the right taper for even coverage. Stable touch with balanced flex. Recommended for use with most paints and primers especially acrylics and enamels. 

Extra Firm:  Durable for exterior use and rough surfaces. Sharp edge performs well in heat and humidity. Solid feel and superior stiffness. Recommended for use with thicker paints and primers especially low voc and other fast drying coatings.

Brush construction also plays a role in determining quality and price. Most professional brushes have wooden handles while consumer brushes typically have plastic handles. The professional handle is nailed in place (not just crimped) so it stays tight and firm under work-a-day conditions. The ferrule (metal band that serves to hold the bristle and handle together) is heavier, and usually non-rusting steel on the professional brushes. Most professional brushes also typically have the longer bristles. Most brushes (consumer and professional) have epoxy settings for the bristles. This is the best way anyone has found to keep the bristles in the brush.

Common Handle Styles

Standard:  Most common handle.

Thin rattail: Thinner version of a standard handle for extra control and lighter weight.

Wide Beavertail: Larger, thicker handle allows for a firm grip for good balance with larger brush heads.

Shortcut:  Compact handle for comfort and control especially in tight spaces.

Choosing the right Brush Size

Angle Sash is the most used brush. The angled end provides added control while edging, especially on vertical surfaces like around windows and doors. They are great for &#;cutting in&#; around trim and into corners. A thin angle sash is narrower and lighter for precise lines and small areas where added precision is necessary. AFlat Sashis designed with a straight end. This is useful when painting baseboards, moldings, or horizontal surfaces.

1&#; to 1.5&#; angle or flat sash: Hobbies and crafts. Window mullions. Tight corners and very detailed areas.

2&#; to 2.5&#; to 3&#; angle sash: Window frames, casings, door moldings, cutting in edges of walls and ceilings.

2&#; to 2.5&#; flat sash: Baseboards, cabinets, furniture, moldings, railings, shutters, gutters.

3&#; to 4&#; flat sash: Exterior siding, masonry, decks, fences, stairs, walls, ceilings, doors.

Tips on Brush Use:

Before starting to paint with a brush, work the bristles back and forth with your fingers to remove any loose bristles or dirt. Prepare the brush for painting by dipping the filaments only halfway into the paint. When the brush is full of paint, tap gently on the sides of the can to release excess paint. This assures maximum pick-up and transfer to the surface. Hold the brush properly by placing your fingers on the ferrule to help steady your hand. The handle should rest comfortably between the thumb and forefinger. Apply paint with the tips of the brush and not the sides. Every so often slap both sides of the brush against an unpainted area to release paint which has accumulated in the top of the brush. This will keep the brush from "fingering". Paint with steady even strokes lifting the brush gradually at the end of the stroke. Don't use the brush to stir the paint - a paint mixing stick does a better job and you don't want the brush to get overloaded with paint. Always clean the brush immediately after use. When storing the brush, avoid standing it on its bristle tips as the weight will cause the edge to bend and curl. If possible, put the brush back into its original package and store the brush hanging up.
