In this article, we will explore this question, discussing the considerations, challenges, and techniques involved in installing moulding on a plastered wall.
Understanding Plastered Walls:
Before diving into the installation process, it is essential to understand what a plastered wall is. Plastering is a technique used to create a smooth and even surface on walls and ceilings. It involves applying a layer of plaster mixture, typically consisting of a mixture of sand, cement, and water, to the underlying surface. The result is a durable, strong, and aesthetically pleasing finish.
Considerations for Installing Moulding on Plastered Walls:
- Wall Condition: The condition of the plastered wall is crucial when considering moulding installation. If the plaster is cracked, loose, or uneven, it may not provide a stable base for attaching the moulding profiles. In such cases, it is advisable to repair the wall before proceeding with installation.
- Material and Weight: Moulding profiles come in various materials such as wood, polyurethane, and plaster. Each material has its own weight and structural characteristics. It is essential to consider the weight of the chosen moulding and ensure that the plastered wall can support it without sagging or causing damage.
- Adhesive or Nails: Depending on the material of the moulding profile and the condition of the plastered wall, you can choose to install the moulding using adhesive or nails. Adhesive is a common method for attaching lightweight moulding to plaster walls. However, for heavier moulding profiles or walls that are not conducive to adhesive bonding, using nails or screws may be necessary.
Installation Process:
- Preparation: Start by ensuring that the plastered wall is clean, smooth, and free from loose debris. Repair any visible cracks, holes, or uneven surfaces using plaster compound or joint compound. Sand down any high spots that can interfere with proper moulding installation.
- Measuring and Cutting: Measure the length of the wall where the moulding will be installed and cut the moulding profiles according to the required lengths. Remember to factor in any corners or angles that may require miter cuts for seamless joins.
- Adhesive Application: If you choose to use adhesive for installation, carefully apply a liberal amount of strong adhesive to the back of the moulding profiles. Press the moulding firmly but gently against the plastered wall, ensuring it adheres evenly. Use painter’s tape or clamps to hold the moulding in place until the adhesive cures fully.
- Nailing/Screwing: In cases where adhesive bonding may not be suitable, nails or screws can be used to secure the moulding. Pre-drill holes through the moulding and into the wall to avoid splitting, then drive the nails or screws through the holes into the wall. Ensure the chosen fasteners are appropriate for the weight of the moulding and provide adequate support.
- Finishing Touches: Once the installation is complete, fill any visible holes or gaps with wood filler or joint compound. Sand the filled areas to create a smooth surface ready for painting or staining. Apply the desired finish to the moulding profiles, matching the existing interior décor.It is possible to install moulding profiles on a plastered wall with proper planning, considering the wall condition, and choosing appropriate installation methods. Whether you opt for adhesive bonding or use nails/screws, taking the necessary steps to prepare the wall and select suitable moulding materials will ensure a secure and aesthetically pleasing installation. With careful execution, your moulding profiles can enhance the beauty and sophistication of your interior space.
