The short answer is yes, corner bead can be installed over pre-existing paint. However, there are some factors to consider before proceeding. The success of this process depends on the type and condition of the paint, the surface preparation, and the materials used.
Factors to consider
Type and condition of the paint
Before installing corner bead over pre-existing paint, you should consider the type and condition of the paint. If the paint is glossy or inadequately adhered to the surface, it may need to be removed or roughened up for the corner bead to properly adhere. However, if the paint is in good condition and has a flat or matte finish, it may be suitable for the installation of corner bead.
Surface preparation
In order for the corner bead to adhere properly, the surface needs to be prepared accordingly. This involves cleaning the surface, ensuring it is free from any dirt, dust, or grease. If the paint is loose or flaking, it should be scraped or sanded away before proceeding with the installation. Additionally, it is recommended to apply a bonding primer to the painted surface to enhance adhesion.
Materials used
The materials used in installing the corner bead can also affect the success of placing it over pre-existing paint. It is recommended to use a high-quality adhesive or joint compound that is specifically designed for corner bead installation. These products often have strong adhesion properties and are capable of bonding well to painted surfaces.
Installation process
Once the surface has been properly prepared, the installation process of the corner bead can begin. It is important to follow the manufacturer’s instructions for your specific type of corner bead. Typically, the corner bead is applied using a trowel or adhesive, ensuring that it is firmly pressed against the wall. The compound is then applied to both sides of the corner bead, covering the edges and providing a smooth transition. Once the compound has dried, it can be sanded and painted to match the surrounding wall.
