Choosing the raw materials
The size of the surface to be painted
For entire walls, the best choice is a roller of 18 cm or more in length; for smaller areas the better option is a mini-roller.
The type of surface
For rough surfaces and generally for outdoors, the best choice is a long-nap roller (18 mm or more), in some cases even a “lined” roller; for smooth or semi-smooth surfaces the better option is a short-nap roller (up to 12-13 mm).
Once the surface to be painted has been identified, the next factor to consider is the choice of pile “fabric”, a selection also influenced by the type of product to be applied.
The main pile fabrics are:
Acrylic is known as corded fabric. It has a medium holding capacity of paints and it has a partial resilience.
Because of these reasons it is suitable for wall interiors and for DIY, water-based paints and waterproof, breathable and acrylic paints. It is good also for all paints on emulsion and alkyd-resins. Excellent escape of bubbles. It’s solvent resistant.
Polyamide is anti-drip fabric . It has a high value of resilience (which means that it comes back in the shape that it was before). It release the colour in an homogeneous way, it offers excellent performance, high quality covering. It guarantees professional performances.
It can be used to apply washable hydro paints, breathable, quartz and corrosive paints. It’s resistant to solvent. It doesn’t become matted and it has a high resistance, so it’s lint free.
It’s suitable for wall paintings, gelatin (short pile length) and paints with silicone resin. It’s proper both for: uneven and rough surfaces, even and smooth surfaces; depending on the surface it is good to evaluate the pile height.
Microfiber is a polyester fabric but it has a frame structure. Thanks to the thin section of the fiber it has a great capacity of absorption and holding capacity, so it’s suitable also for very liquid products: insulating, impregnated and liquid paints. It’s anti-drip.
It has a constant release of color. It’s solvent resistant and lint free. It creates great and homogeneous results and it has a high quality covering.
It’s suitable for acrylic paint and varnish: lacquers, enamels, primers, sealers and dispersions for cleaning. It’s suitable for: wood stains and wood preservatives treatment. It is very easy to clean – wash the roll with any solvent after using and rinsing with water prolong the service life.
Mohair and Velour
Mohair and Velour are similar, the first one is obtained from goats wool and the second one is made thanks to weaving yarns in lamb’s wool.
It has a homogeneous application and very good resilience.
It has an excellent resistance to solvent. It’s suitable to be used with: enamels, solvent-based paint, waterproof dense paint, synthetic resins and anticorrosive products, varnish with two components polyurethane and epoxy resins.
Foam is suggested to be used for fine painting and with paint to be applied in a thin way.
We could obtain the effect of an orange peel with low density paint. It creates homogeneous result and it is lint free.
It is suitable for special effects and decoration for acrylic paints with medium viscosity and the final result depends also on the type of foam (e.g. number of the cell).
Our brush production initially used pig bristles of Italian and then Chinese origin, which were cooked, prepared, and readied for mixing with other bristles, or used alone, according to customer needs.
Beginning in the 1980s, however, the continued drastic reduction in availability and quality of this raw material led us to research and implement new synthetic fibres, from which we have also achieved increased performance.
The selection of the best raw materials starts from the bristles: the main component of the brush.
Thanks to their capillarity absorption properties the value of natural bristles is the greater holding capacity, so it naturally guarantee any drop loss.
The value of synthetic bristles is the abrasive resistance, especially on rough and uneven surfaces.
White is elastic and has a great holding capacity. It has a conical structure and feathered top. These bristle are suitable for water based paints. It is an organic material, therefore it can absorb and retain very fluid paints.
The mix of different qualities (Chungking, Shanghai and Hankow) is very versatile and have a large diffusion.
Black is elastic and has a great holding capacity.
The structure of the filament is conical and feathered on the top. It’s suitable for thick and viscous paints that need a good lay down and solvent enamels.
Synthetic filaments can resist to light solvents except PVC, and have a small holding capacity.
Except for specific uses with thick and viscous paints, it is in the habit doing synthetic/natural mix filling, in order to have the values of both: greater holding capacity and abrasive resistance.
Krex is a synthetic fiber of latest generation. It’s elastic, reactive and and it has a conical structure that facilitates the drafting of viscous products. It’s specific for acrylic and water-based varnish paints and thick and gelatinous enamels.
It has a small holding capacity. Krex/white bristles mix filling is suitable for quartz thick paints on abrasive surfaces.
PVC is highly wear and tear resistant, this is why it is very often used also in the industrial sector. Suitable only for water-based paints.
It has to be used only with natural mixed filling, and this kind of paintbrush is suitable only for first coating.
