Essential Materials and Tools for Your DIY Modern House Number Project

Before you begin, gather the following materials and tools. Having everything on hand will ensure a smooth and efficient crafting experience.

Weather-Resistant Wood or Fiberboard: Choose a material suitable for outdoor use, such as redwood, cedar, or Extira (an exterior-grade MDF alternative). Extira offers the workability of MDF but resists water damage. Redwood and cedar provide natural beauty and durability.
Modern House Numbers Template: Download a printable template to guide your cutting. You can find various templates online, or even design your own for a truly unique look. Download a Template Here
Spray Adhesive: Use spray adhesive to temporarily attach the template to your chosen material, ensuring accurate cutting.
Coping Saw or Jigsaw: A coping saw is ideal for intricate curves, while a jigsaw is better suited for straight lines and larger cuts. Choose the tool that best suits your skill level and the complexity of your design.
Sandpaper (Rough and Fine Grit): Sandpaper is essential for smoothing rough edges and creating a professional finish. Start with a rough grit to remove imperfections and then move to a finer grit for a smooth surface.
Wallboard Joint Compound and Oil-Based Primer (Optional but Recommended): These materials are particularly beneficial when working with MDF or Extira. Joint compound fills imperfections in the edges, creating a seamless surface for painting. Oil-based primer seals the material and provides a smooth base for the final paint coat.
Exterior-Grade Paint: Select a high-quality exterior paint that can withstand the elements. Consider a metallic finish, such as aluminum or brushed silver, to mimic the look of Neutra’s original metal designs.
Sponge Brushes: Sponge brushes provide a smooth and even application of paint, minimizing brush strokes and creating a professional finish.
10-24 Nuts and Bolts or Threaded Rod: These will be used to create standoffs, allowing your house numbers to float slightly away from the wall, adding depth and visual interest.
Two-Part Metal Epoxy: Epoxy is used to securely attach the nuts to the back of the house numbers. Choose a strong, reliable epoxy specifically designed for metal bonding. JB Weld is a popular and effective option.
Electric Drill and Drill Bits: A drill is needed to create pilot holes for the bolts and to countersink the nuts into the back of the house numbers. Choose drill bits that are appropriate for the size of your bolts and nuts.

MDF board ready for cutting into house numbers — Starting with a Suitable Material: MDF, Extira, or Wood

Step 1: Material Selection and Preparation

The foundation of your DIY house numbers lies in choosing the right material. While metal offers a sleek and durable option, it often requires specialized tools and expertise. Therefore, a wood-based product painted to resemble aluminum provides a cost-effective and accessible alternative.

For optimal weather resistance, consider Extira, redwood, or cedar. Extira, an exterior-grade panel product, mimics the properties of MDF but is impervious to water damage. Redwood and cedar boast natural decay resistance and add a touch of natural beauty. You can often obtain free samples of Extira from the manufacturer, potentially allowing you to complete this project at no cost! Local lumber yards typically sell these materials in smaller quantities, making them an affordable choice.

Using a jigsaw to cut out the modern house number template — Cutting the Numbers: Precision is Key

Step 2: Cutting Out the House Numbers

Once you’ve selected your material, it’s time to bring your house numbers to life. Begin by printing the template at full size to achieve 4″ tall numbers. Adjust the size as needed to suit your preferences and the specific application.

Securely attach the template to the panel using spray adhesive, ensuring a firm bond to prevent slippage during cutting. Employ a jigsaw or coping saw to carefully cut out the numbers. Instead of cutting directly on the black line, aim for a 1/16″ margin on the outside. This provides room for sanding and ensures a clean, precise finish.

Prioritize cutting internal angles and complex curves first, followed by the straight lines that connect the shape to the rest of the panel. This approach minimizes the risk of damaging the more intricate details. Important Note: Learn from my mistake! Cutting in the order described above will yield better results than the method shown in the photo.

Adding nuts to the back of the numbers for a floating effect — Creating the Standoffs: Adding Depth and Dimension

Step 3: Creating the Standoffs

To create a visually appealing floating effect, adding standoffs to the back of your house numbers is essential. This technique involves attaching nuts to the back of the numbers and then securing bolts to the nuts, creating a space between the numbers and the wall.

While I initially attached the nuts after painting, I highly recommend doing it beforehand. This prevents the need for touch-up painting later on. Drill a 1/4″ hole into the back of each number at its thickest points. This will serve as the anchor point for the nuts.

Painting the numbers with exterior-grade paint — Priming and Painting: Achieving a Flawless Finish

Step 4: Priming and Sealing (Optional but Recommended)

Preparing your house numbers for paint is crucial for achieving a professional-looking finish. For optimal results, especially when working with MDF or Extira, consider using the MDF painting method. This involves sealing the “edge grain” with joint compound and then applying an oil-based primer to the faces.

This process may seem redundant since you’ll be covering everything with oil-based paint, but it significantly enhances the final result. The joint compound fills any imperfections in the edges, creating a smooth, seamless surface. The oil-based primer seals the material, prevents paint absorption, and provides a uniform base for the final coat.

After applying the joint compound and primer, thoroughly sand the entire surface to ensure a smooth, even texture. This step is crucial for achieving a flawless painted finish.

Applying multiple coats of exterior paint — Painting: Mimicking the Look of Brushed Aluminum

Step 5: Painting Your Modern House Numbers

With your house numbers properly primed and sealed, it’s time to apply the exterior paint. Apply at least two coats of exterior paint, allowing each coat to dry completely before applying the next. For a sleek, modern look, consider using a metallic paint such as Rustoleum’s “Aluminum”.

Sponge brushes tend to produce a smoother finish compared to bristly brushes. On the final coat, use down strokes only to mimic the look of brushed aluminum, adding a touch of sophistication and authenticity to your DIY house numbers.

Step 6: Final Assembly and Installation

Finally, epoxy the nuts into the cavities on the back of the house numbers and allow the epoxy to dry completely. Take care to prevent any epoxy from getting into the threads of the nuts, as this will hinder the attachment of the bolts.

To attach your new modern house numbers to the wall, use 10-24 bolts with the heads removed using a hacksaw. Alternatively, you can use threaded rod, which is available in the weldable steel section of most hardware stores. Cut the threaded rod to the desired length.

Choose an anchor designed for the specific material of your exterior wall or mailbox. Proper anchoring is crucial for ensuring that your house numbers are securely attached and can withstand the elements.

The Result: A Stylish and Affordable Upgrade

Excluding drying times, this entire project took approximately 1 1/2 hours to complete and cost around $19. This affordable and rewarding DIY project is a fantastic way to elevate your home’s curb appeal and add a personal touch. You can’t beat that!
