Painting and rendering have been popular choices for many homeowners because they offer a lot of bang for your buck and can give a home a fresh, new look. But it’s important to understand that, before any painting or rendering job, surface preparation is crucial. What you do before applying paint or render can determine the success or failure of the project.
In this article, we share four reasons why surface preparation is so important for paint or render work.
1. Surface Preparation Enhances Adhesion
Paint and render need to stick to the surface they are applied to, or they will peel and crack. Surface preparation helps to increase adhesion between the painted/ rendered surface and the coating you are applying. A properly prepared surface enables better penetration and bonding of the paint or render with the surface. This ensures the longevity of the project and reduces the need for frequent repairs.
2. Surface Preparation Eliminates Blemishes
Surface preparation removes dirt, grime, stains, and other blemishes, which can affect the finished product. Old paint that is faded or peeling may also be removed. Surface preparation helps to ensure that your paint or render looks smooth, uniform, and has a clean finish that will increase the value of a home.
3. Surface Preparation Prevents Mould and Mildew
Painting or rendering on a moist or damp surface is a recipe for mould, mildew, and algae growth. Surface preparation includes cleaning, drying, and primer application, which helps to create a surface that is less susceptible to moisture. Paint or render that’s applied over a damp surface will quickly lose its adhesion and peel away. A well-prepared surface reduces the risk of moisture, which can be harmful to a home’s structure.
4. Surface Preparation Saves Time and Money
Surface preparation is a time and cost-saving measure. Proper surface preparation ensures the longevity of your project. A poorly prepared surface, on the other hand, may require additional coats of paint or render to cover up imperfections and can result in costly repairs.
A properly prepared surface is always the foundation of high-quality paint or render work. Not only does it enhance adhesion, but it eliminates blemishes, prevents mould growth, and saves time and money. Remember that it’s always better to invest more time in surface preparation than to cut corners. As the saying goes, “preparation is key”, and if you take on board, you can expect a smooth and successful paint or render project.
