This step not only enhances the appearance but also prevents water from seeping behind the molding, which can lead to damage over time.
Finishing Touches: Painting and Expansion Considerations
With your PVC brick molding securely attached, the project is nearing completion. However, two crucial finishing touches can significantly impact the long-term appearance and performance of your installation: painting (if desired) and addressing the natural expansion and contraction of PVC.
Painting PVC Brick Molding
While many PVC brick moldings come pre-finished in a variety of colors, you may choose to paint yours to match your home’s existing color scheme or to achieve a custom look.
Preparing for Paint
Proper preparation is key to a successful paint job. Start by thoroughly cleaning the PVC surface with a mild detergent and water to remove any dirt, grease, or residue. Rinse well and allow it to dry completely. Lightly sand the surface with fine-grit sandpaper (220 grit or higher) to create a better surface for the paint to adhere to.
Selecting the Right Paint
Choosing the right paint is critical for PVC. Exterior-grade acrylic latex paint is generally recommended due to its flexibility and durability. Avoid oil-based paints, as they can become brittle and crack over time on PVC.
Look for paints that specifically state they are suitable for use on plastics or PVC.
Application Techniques
Apply the paint in thin, even coats using a high-quality brush, roller, or sprayer. Allow each coat to dry completely before applying the next. Two coats are typically sufficient for full coverage and a lasting finish.
Addressing Expansion and Contraction
PVC, like all plastics, expands and contracts with temperature changes. Understanding this characteristic and accounting for it during installation is essential to prevent buckling, warping, or joint separation in the future.
Understanding PVC Movement
The amount of expansion and contraction depends on the length of the PVC brick molding, the temperature range it experiences, and the coefficient of thermal expansion of the specific PVC material. Longer runs of molding will experience more movement than shorter pieces.
Leaving Expansion Gaps
The primary way to accommodate expansion and contraction is to leave small gaps at the joints between pieces of molding. These gaps allow the PVC to expand and contract freely without putting stress on the fasteners or adhesive.
The size of the gap will depend on the factors mentioned above, but a general rule of thumb is to leave a gap of about 1/8 inch for every 10 feet of molding. Consult the manufacturer’s specifications for more precise recommendations.
Flexible Sealants
When sealing the edges of the molding with caulk, use a high-quality, flexible sealant that can accommodate movement without cracking or losing its seal. Polyurethane or silicone-based caulks are good choices.
By carefully considering painting options and accounting for expansion and contraction, you can ensure that your PVC brick molding installation looks beautiful and performs well for years to come.
