Ask expert painters in Sydney, and they will tell you that it is the preparation before a painting that determines the success of a painting project. Painting itself is usually the last step. Adding one coat of paint to an unprepared wall does not cover its flaws, but ends up highlighting them. Preparing a wall before a paint job ensures not just better, but also longer-lasting results. Here are the different ways a wall can be prepared and their impact on the final look.
Dirt and grime need to be cleaned before painting a wall. Without proper cleaning, the underlying dirt particulates will mix with the paint leading to an uneven and dirty wall. This may also slightly change the appearance of the paint colour you chose. A professional painter will always first wash the surface before starting a paint job. This is usually done using pressure washing. Painting the walls once they are clean makes them look vibrant and the paint colours to shine through. It also enables the paint to stay on the walls for a longer time.
Scraping the Old Paint
Flecks of old paint on the walls can create uneven surfaces. Painting over such surfaces makes the final results look unprofessional. It can result in bumps and unpainted areas across the wall. Scraping or sanding the wall allows a professional painter to create an even surface to apply the paint. This small step can help the painter to achieve clean lines and cover every inch of the wall.
Filling Up Holes
It is common for older walls to develop cracks or holes dues to regular wear and tear. A wall filled with cracks and holes is visibly unmaintained and painting over them will not cover the problem. The cracks and holes will just show up over the new paint, completely ruining the new wall. So, they need to be filled beforehand. In the absence of cracks and holes, the integrity of the wall is restored. The painting job after this preparation means a smoother finish and a stronger wall.
Certain walls suffer from leaks, mould infestation, and other such problem. In this case, it is essential to safeguard a wall using a variety of specialised coats available in the market. A professional painter is well-versed in understanding the issue a wall is suffering from and correcting it using protective paint. This will help in eliminating problems such as wall bubbling, paint flaking, among others. With a specialised chemical protecting the wall, it looks visibly better and lasts longer.
