Have you ever applied back rolling techniques after distributing your paint through airless spray? You better try this technique. Painters who choose not to back-roll following a spray application risk facing difficulty with repair and touch-up. Besides, it will be difficult to achieve on a smooth non-textured surface if no back-rolling is carried out. You can choose to either applied roller or spray. But, at the end back-rolling the spray will always deliver the best overall appearance and outcome. Below are more reasons why you have to back rolling your paint.
What is Back-Rolling?
“Back-rolling” is better known as a term in the paint industry. It describes the manual process of dry rolling. The freshly painted surface with a short to medium nap synthetic roller immediately following the spray application of water based paints onto walls and ceilings, whilst the paint is still wet.
Professional painter knows that back-rolling should be carried out as standard practice, especially if it carries these three specific reasons:
- Texture: By applying the roller onto the newly sprayed surface, you can get more soft texture. As a result, you’ll scatter the light more uniformly and effectively help to disguise or hide surface flatness variations, small surface imperfections or any other blemish or surface defect which will sometimes occur after you paint them.
- Adhesion: The roller will gently press the paint into the surface and therefore assist in developing maximum adhesion of each coat to the previous layer. In fact, you already have a slight texture from the paper surface on new plasterboard that provides an anchor for the paint to stick to.
- Surface Variations: When the plasterer sanded off the set joints, you can have a roller to flatten any raised nap or paper fibers on new plasterboard.
The plasterboard manufacturers have advocated the process of back-rolling, ever since the spray application becomes a common practice.
