Frequently Asked Questions

What Types Of Decorative Moulding Are Best For Plaster Walls?

For plaster walls, it’s ideal to choose moulding materials that are lightweight yet durable, such as polyurethane or high-density foam. These materials are easier to install and less likely to cause damage to the existing plaster compared to heavier wood mouldings. Additionally, they can be intricately designed, making them suitable for both modern and traditional interiors.

How Do I Prepare My Plaster Walls Before Installing Moulding?

Preparing your plaster walls involves several key steps: First, repair any cracks or damage to ensure a smooth surface. This may include filling cracks with plaster or a flexible filler and sanding down uneven areas. Next, clean the walls to remove dust and debris, and apply a primer to help the adhesive and moulding adhere more effectively to the surface.

Can I Install Decorative Moulding Myself, Or Should I Hire A Professional?

Installing decorative moulding can be a DIY project if you have the right tools and a basic understanding of carpentry. However, for intricate designs or large projects, it might be beneficial to hire a professional. A skilled installer can ensure that the moulding is cut and fitted perfectly, which is crucial for achieving a polished look, especially in rooms with uneven walls or complex angles.

What Is The Best Way To Cut Decorative Moulding For A Perfect Fit?

To cut decorative moulding accurately, use a mitre saw equipped with a fine-toothed blade. Measure the wall space carefully, and plan your cuts to ensure tight joins, especially at corners. For inside corners, cope cuts are preferable as they allow for the most precise fit. Always measure twice and cut once to avoid wastage of materials.

How Do I Maintain The New Moulding Once It’s Installed?

Maintaining decorative moulding involves regular dusting to prevent the buildup of dirt and debris. For deeper cleaning, use a soft cloth slightly dampened with water and a mild detergent. Avoid harsh chemicals that can damage the finish. Periodically check for any gaps or cracks in the caulking, especially in areas with high humidity, and reapply caulk as necessary to keep the joints sealed and looking fresh. Touch-up paint may also be required from time to time to keep the moulding looking its best.
