In this particular case, I was repurposing a beautiful Venetian-style cast iron table base. The table base itself already hit on my personal design and style preferences. So, the top of the table was really the biggest decision to make.

Here are a few key factors to consider:

Space and Size

Evaluate the available outdoor space and determine the optimal size for your table. Take measurements and consider the surrounding area to ensure ample room for movement and seating.

Design and Style

Decide on the overall design and style that aligns with your outdoor aesthetic. Consider the existing decor, materials, and colors to ensure a cohesive look.


Think about how you’ll be using the table. Will it primarily serve as a dining area, a gathering spot, or a multi-functional space? This will influence the size, shape, and features you incorporate.

Materials and Budget

Take stock of the materials needed for the project, considering both durability and aesthetic appeal. Also, establish a budget to guide your choices and prevent unexpected expenses.

By taking the time to plan and consider these aspects, you’ll set a solid foundation for the successful construction of your DIY outdoor patio table. Let’s move forward and bring your vision to life!

Step-By-Step Instructions

In this section, I will walk you through the process of how I transformed a repurposed cast iron base into a beautiful outdoor table. It’s simple, beautiful, and budget-friendly!

Choosing the Table Top

Now this step I thought about and actually looked around for quite some time. There are so many directions you could go in.

At one point I had my heart set on using an old electrical spool top since it’s already treated wood. Also, they come large enough to be a tabletop.

6 Options for Tabletops

  1. The top of a wooden electrical spool.
  2. A repurposed tabletop from a thrift table.
  3. Using a Kreg jig, pocket holes, and reclaimed wood to build a tabletop.
  4. Create a mold and pour your own concrete tabletop.
  5. Use a wood round to create a tabletop.
  6. Use scrap wood glued and secured with pocket holes, then cut into a round table top.

These are great options for tabletops depending on your skill level and tools available. I opted to go with the simplest option.

Clean & Coat the Cast Iron Table Base

Cast iron is ideal for outdoor patio tables due to its durability, stability, and strength. It withstands weather elements, provides a secure base, as well as supporting heavy tabletop materials. With its timeless look, low maintenance requirements, and versatility in design, cast iron adds both elegance and functionality to outdoor spaces.

Before we put the table together first we need to clean it!

How to Clean a Cast Iron Table Base

Cleaning an older venetian style cast iron tablebase with soap water and a scrub brush.

Step-by-Step Instructions

To clean a cast iron table base, you can follow these steps:

Step 1 – Remove Loose Debris

Start by brushing or wiping off any loose dirt, dust, or debris from the surface of the cast iron base. Use a soft brush or a dry cloth to gently remove the particles.

Step Two – Prepare a Cleaning Solution

Mix a solution of warm water and mild dish soap in a bucket or basin. Avoid using harsh chemicals or abrasive cleaners as they can damage the cast iron.

Step Three – Scrub the Surface

Dip a soft brush or sponge into the cleaning solution and gently scrub the cast iron base.

Pay attention to any areas with stubborn stains or grime. For tough spots, you can use a nylon scrub brush or a toothbrush to scrub more vigorously.

Step Four – Rinse Thoroughly

Once you’ve scrubbed the entire surface, rinse the cast iron base thoroughly with clean water. Make sure to remove all traces of soap residue.

Step Five – Dry Completely

Use a clean towel or cloth to dry the cast iron base thoroughly. Moisture can lead to rust, so ensure that the surface is completely dry before proceeding. I also let my table base sit in the summer sun.

Step Six – Apply a Protective Coating

To prevent future rust and corrosion, consider applying a protective coating to the cast iron base.

You can use a clear coat spray or apply a thin layer of oil or wax designed for metal surfaces. Follow the product instructions for application and drying times.

By following these steps, you can effectively clean and maintain the cast iron table base, keeping it in good condition and extending its lifespan. Regular cleaning and maintenance will help preserve its appearance and functionality for years to come.

Finishing and Staining the Tabletop

To enhance the visual appeal and protect your outdoor table, applying a finish and stain is essential. Follow these steps for a successful finish:

Step-by-Step Instructions

Step one – sanding

Begin by sanding the entire tabletop to create a smooth surface. Start with coarse-grit sandpaper (80 grit is fine) and gradually move to finer grits (220 grit) until achieving the desired level of smoothness.

Step two – Cleaning

Thoroughly remove all dust and debris from the sanding process. Use a tack cloth or a damp cloth to ensure a clean surface for the finish.

step three – staining (optional)

If you desire a colored or richer tone, apply an outdoor-rated stain after the finish has dried. Test the stain on a small, inconspicuous area first to ensure you achieve the desired color.

I chose to apply a single coat of Early American by Varathane.

step four – applying a finish

Choose an exterior-grade finish suitable for your tabletop material. I, unfortunately, chose an improper finish, which I learned after a rain. Polycrylic is water soluble so not a suitable outdoor finish.

I would recommend a polyurethane, made for exterior use. Apply the finish evenly using a brush or a lint-free cloth, following the manufacturer’s instructions. Allow it to dry completely between coats.

By carefully following these steps, you can achieve a beautifully finished and stained tabletop that enhances the appearance and durability of your outdoor table. It’s time to add the perfect finishing touch to your DIY project!

Installing the Top to the Base

Now that we have successfully prepared the base and tabletop of our DIY outdoor patio table, it’s time to bring everything together by installing the top to the base.

This crucial step will ensure stability, durability, and a seamless connection between the two components.

Installing the base to the tabletop the easiest way possible, upside down.

How to Easily Install the Tabletop to the Cast Iron Base

In this section, we’ll guide you through the process of securely attaching the tabletop to the base. This is the simplest way I have found to do it. And I know because this is the second table I’ve made from a cast iron base.

Let’s get ready to complete our DIY project and enjoy the satisfaction of a beautifully assembled table!

Step-by-Step Instructions

Carefully put your cast iron base on top of the tabletop while making a DIY outdoor patio table. Installing the tabletop to the base, the easy way.
Step one – upside-down placement

To protect your newly finished top, lay something soft like a rag on the ground. Then turn your tabletop upside-down.

At this point carefully turn your cast iron base upside-down on top of the tabletop.

Measuring around all the main points to ensure the tabletop was being installed in the center of the DIY outdoor patio table base.
step two – centering the base

Take your tape measure and take your time to ensure the tabletop is properly centered with the table base.

Trust me, if it isn’t you will notice and it will bother you.

Screw your panhead screws into the tabletop from the bottom of the base for the DIY outdoor patio table with your drill.
step three – drilling the holes & installation

Since the tabletop is 3/4″ wood and the table base is about 1/4″ thick, I chose #14 1″ Panhead screws.

Mark your holes and carefully drill shallow pilot holes so the wood doesn’t split.

Then slowly drive each screw into place.

Other Outdoor Furniture Projects You Can DIY

While you’re on a DIY kick, you may as well just check all of these other great projects off your to-do list. Any of these amazing DIY projects would make a great addition to any back patio.

Typical Woodworking plans require a few tools & supplies like:

The best base for an outdoor table is a durable and weather-resistant material like cast iron or stainless steel. These materials offer excellent stability, withstand outdoor conditions, and resist rust and corrosion. Additionally, they provide a sturdy foundation for the tabletop, ensuring a long-lasting and reliable outdoor table.

Yes, cast iron is suitable for outdoors. It is highly durable, able to withstand outdoor elements, and resistant to rust when properly maintained. Cast iron is a popular choice for outdoor furniture due to its strength, stability, and longevity.

To prevent cast iron from rusting outside, apply a protective coating such as an exterior-grade paint, enamel, or a specialized outdoor metal sealer. Regularly clean the surface, keep it dry, and avoid leaving water or moisture on the cast iron. Applying a layer of oil can also provide additional protection.

While it is not necessary to oil the outside of cast iron, applying a thin layer of oil can provide an extra layer of protection against rust. This is especially beneficial for cast iron used outdoors, as it helps to repel moisture and prevent oxidation.

For outdoor cast iron, a food-grade mineral oil or a specialized outdoor metal oil, such as linseed oil or tung oil, are commonly recommended. These oils provide good protection against moisture and oxidation, helping to keep the cast iron in good condition.
