The Painting Solution: Episode 2
Welcome to the 2nd instalment of The Painting Solution!
Having completed the high-pressure cleaning of all surfaces, it’s time to begin surface preparation of the various substrates. So, while the team are busy repairing plaster cracks, cutting expansion joints etc. let us head over to the paint brush and roller section to source the perfect tools for the upcoming job.
Choosing the Right Paint Brush
Generally, there are three types of paint brushes:
- Those made of natural-hair bristles
- Those made with synthetic materials (usually nylon or polyester) and,
- Those made with a blend of natural hair and synthetic
Traditionally, natural bristle brushes are preferred for use with solvent-based (oil- or alkyd-based) paints, especially for enamel or finish work. Natural bristles are hollow and can absorb the water contained in a latex paint, causing them to swell and become soft and limp (like your own hair when it is wet). Most synthetic brushes work well with both latex and solvent-based paints, but always check the manufacturer’s recommendations on the brush. Some of the solvents used in solvent-based paints can break-down the compensation of a synthetic bristle-once again check the label. The same rules when choosing the right paint brush apply to paint rollers: synthetic vs. natural (wool).
High quality or more expensive brushes have distinct advantages over the cheaper ones. First, a high-quality brush will finish the job more quickly. This is because a top-quality brush can “hold” more paint in reservoir, which means you will spend less time “painting the can” than applying the paint to the surface. A top-quality brush will also not shed bristles like a cheaper brush, because of how firmly the bristles are seated in the ferrule (the metal band that attaches the bristles to the handle), and determined by the material used as plugs (space plugs inside the ferrule that bond the bristles in the ferrule, add taper to the bristles, and finally create “wells” in the centre of the bristles to hold paint) in the ferrule. Also, a top-quality brush will have a tapered end, which means there are shorter bristles on the outside and longer bristles in the centre. Tapered bristles give the painter more control over where and how much paint goes onto the surface, which is important to consider when choosing the right paint brush.
Choosing the Right Paint Roller
The fabric is referred to as pile or nap. The nap type and length determines the finish, with the longer nap often leaving a pattern on the surface. The choice of roller is dependent on the type of paint being used and the surface being painted. Solvent-based paints are generally applied with a short pile mohair roller onto smooth surfaces. Water-based paints are generally applied with sheepskin, bended synthetic of foam rollers.
Keep the following pointers in mind to make life easier for yourself:
- Long pile is used for rough surfaces
- Foam is use for smooth and semi smooth surfaces
- Medium pile is used for semi rough and textured surfaces
How does a good quality roller benefit me and my painting project you might ask? The obvious reasons would be it saves time and produces a quality finish. Quality rollers hold more paint and allow for an even film thickness, meaning it levels the paint finish without shadows or valleys. Cheaper rollers often result in many coats having to be applied, which is both costly and time consuming.
