An Expert’s Guide to Restoring Cornice Moulding

Welcome! You’ve arrived here to gather in-depth knowledge about repairing and restoring cornice moldings. These moldings are decorative architectural features that demand the utmost precision and expertise for successful restoration. Today, we will delve into this detailed journey of cornice molding restoration guided by our veteran contractor and glean insights into the nuances of this intricate process.

Step-by-Step Procedure of a Cornice Moulding Restoration Project

Each restoration project presents its unique set of challenges and tasks. However, the basic steps followed in any typical cornice molding restoration project are as follows:

  1. Old Paint Removal: The first step involves stripping off the old paint. This can often result in deep gouges in the wood, as approximately 1/4 inch of the surface might be painted.
  2. Filling in Holes with Putty: Post paint removal, any resultant holes are filled using a robust putty filler, a substance renowned for its efficacy even in car repairs.
  3. Sealing Wood Knots: In the case of wood knots, shellac – a high-coverage sealant made from resin, is employed to fill them.
  4. Sanding: The entire surface is subjected to thorough sanding to achieve a smooth texture.
  5. Priming: A layer of water-based primer is applied over the whole surface to prepare a seamless base for the upcoming paint layer.
  6. Painting: After the primer dries completely, two coats of water-based paint are applied, often maintaining the color of the previous paint for consistency.
  7. Stucco Renovation: The cornice’s stucco (or roughcast) surface is scraped and repainted to match the existing color.

Selecting the Right Colour for Your Cornice

The color choice for a cornice largely depends on the client’s preference. Some prefer bold and bright colors like red or sky blue, while others may opt for subtler tones. However, it is crucial to remember that vibrant colors usually demand more coats, increasing the time and effort required.

When planning to transition from a darker shade to a paler one, a high-quality primer can save you from multiple finishing coats and ensure an appealing result.

Choosing the Ideal Paint for Cornice Mouldings

We strongly recommend water-based 100% acrylic paint and primer for cornice moldings. With rising environmental consciousness, water-based paints have become the go-to choice for most outdoor projects. These paints, unlike their oil-based counterparts, are not only eco-friendly but also easier to handle.

For sealing wood knots, shellac proves to be a fantastic choice. It effectively hides the knots, preventing them from showing through the paint.

Time Requirement for Cornice Moulding Restoration

The timeline for a cornice molding restoration can vary significantly depending on the specific condition of the cornice and weather conditions. While an ideal weather situation can help complete the project in less than three days, adverse weather or more intensive repairs may stretch the timeframe to a week or more.

Significant Challenges Encountered in Cornice Moulding Restoration

Two primary challenges are usually encountered in such restoration projects:

  1. Weather Conditions: Since painting is not feasible under too humid or hot conditions, ensuring a minimum of two days of favorable weather after renovation is vital. Rain, before the paint dries completely, can cause the paint to drip, necessitating a redo.
  2. Height: The restoration of cornice moldings requires specific tools for working at height. It demands skilled professionals comfortable with height-related tasks and the frequent moving of ladders to cover the entire cornice molding.

Cost of Cornice Moulding Restoration

The cost of cornice molding restoration can range from $800 to over $10,000, contingent upon multiple factors such as the type of roof, the cornice, and the extent of prep work required. Be prepared for higher costs if extensive repairs are needed, as in most cornice molding restorations.

The Necessity of Hiring a Specialized Contractor

While a conventional painter can carry out the task, a contractor specializing in cornice molding renovations can provide a more professional outcome and save time. Their experience and expertise allow them to perform the job efficiently and precisely, ensuring your restored moldings last at least 20-30 years.

Optimal Time for Cornice Moulding Renovation in Canada

Given the Canadian weather, the onset of summer, particularly June, is an excellent time for undertaking such renovation projects. However, due to the high demand for other tasks, such as patios, most contractors have better availability during mid-summer.

Special Considerations for Heritage Buildings

If your building has heritage status, additional rules will dictate the renovation process. Such facilities demand respect for the original style and avoidance of synthetic materials. Thus, it’s prudent to hire a professional well-versed in restoring heritage buildings that can replicate the cornice’s original style closely, even in an advanced state of decay.
