Understanding the essential aspects of wallpapering over painted plasterboard is crucial to ensure a seamless and durable application. This article delves into the key considerations, providing insights into surface preparation, adhesive selection, and application techniques to achieve a professional-looking finish.

Surface Preparation

Prior to wallpapering, the painted plasterboard surface must be thoroughly cleaned to remove any dirt, dust, or grease. Sanding the surface lightly with fine-grit sandpaper creates a slightly rough texture that enhances the adhesion of the wallpaper paste. Any imperfections or holes should be filled and smoothed out using a suitable filler.

Adhesive Selection

The type of adhesive used for wallpapering over painted plasterboard depends on the weight and material of the wallpaper. Heavy-duty wallpaper adhesives are recommended for heavier wallpapers, while lighter adhesives are sufficient for lighter materials. It is essential to select an adhesive specifically designed for use on painted surfaces to ensure optimal bonding.

Application Techniques

When applying wallpaper over painted plasterboard, it is crucial to follow the manufacturer's instructions carefully. Apply a thin, even layer of adhesive to the back of the wallpaper and allow it to set for the recommended time. Position the wallpaper on the surface, carefully aligning the edges, and smooth it out using a wallpaper brush or squeegee to remove any air bubbles.

Finishing Touches

After the wallpaper is applied, use a sharp utility knife to trim any excess around the edges and corners. To ensure a secure bond, press down firmly along the seams and edges using a wallpaper roller or seam roller. Allow the wallpaper to dry completely before using the room to prevent any damage.
