When undertaking any painting job, it’s important to not only have the correct paint but also the most suitable painting tools and accessories. For example, there may be times when a brush is too insufficient for the area to be painted and a roller may be more appropriate, or perhaps a spray paint dispenser would be more effective when covering an extensive project.Paint RollersA paint roller comprises a frame and sleeve, which can be made from either foam, polyester or microfibre. The sleeve absorbs the paint and transfers it evenly to the wall, floor or ceiling. They are usually removable so they can be cleaned or replaced with ease.They are available in a variety of widths to suit the size of area to be painted. There are also 2 diameters of roller; 1.5 inch (38mm) and 1.75 inch (44mm) with the larger size preferred by professionals.Sleeves are available with different thicknesses of pile depending on the roughness of the surface being painted. The rougher the surface, the longer the pile that is required. Knowing what type of roller you need before starting your project will help you achieve the best finish possible.Paint TraysPaint trays are available in different widths to suit the different width rollers. They have a deeper section, to hold the paint, and an angled slope, used to roll off excess paint and ensure there is an even quantity held in the roller pile.
