Oil Based vs Water Based vs Penetrating Stains: Which Finish is Better for Outdoor Wood Furniture

Before we dive into specific finish, you need to understand the main types of finishes and when to use each one.

1. Oil-Based Finishes

They soak into the wood deeper and create a tougher protective layer. Oil-based finishes give wood that warm, amber glow that gets richer over time.

So, you can choose the best oil-based for outdoor wood furniture when:

You have expensive furniture worth protecting long-term
Your furniture gets extreme sun, rain, or temperature changes
You like the traditional warm, honey-colored look
You don't mind stronger smells and need mineral spirits for cleanup
You want maximum durability and don't mind waiting longer between coats

2. Water-Based Finishes

These finishes are the modern, user-friendly option. They dry lightning-fast, have almost no smell, and clean up with soap and water. Also, water based finishes keep outdoor wood furniture looking natural without changing its color.

Pick the best water-based for outdoor wood furniture when:

You want to finish fast (sometimes 5 coats in one day)
You're working indoors or in areas where strong smells are a problem
You want to keep light woods looking light (no amber color change)
You prefer easy soap-and-water cleanup
Environmental friendliness matters to you

3. Penetrating Stains (Like Ready Seal)

The third best wood finish for outdoor furniture isn’t really oil or water-based in the traditional sense. Instead, they're designed to soak deep into wood fibers rather than form a protective film on top.

You can choose penetrating stains when:

You want a foolproof application
You have large areas to cover
You prefer a natural, semi-transparent look
You want easy maintenance (simply reapply when it fades)
Film-forming finishes have failed on your wood before

How to Choose the Best Finish for Outdoor Wood Furniture?

Just like you wouldn't use the same SPF for a quick walk to the mailbox versus a day at the beach, different outdoor wood furniture needs different levels of finish protection. So, our advice besides oil-based, water-based, and penetrating stains, is to match what you have to what it needs.

1. What Kind of Furniture Are You Protecting?

Expensive furniture (teak, mahogany, high-end sets): If you spend serious money on your outdoor furniture, protect it with serious products. TotalBoat Gleam costs $125 per gallon, but it's the same finish they use on million-dollar yachts. This oil-based finish gives you that beautiful amber glow that makes expensive wood look even better, and it lasts for years with just annual touch-ups.
Regular patio furniture (cedar, pine, most store-bought sets): For everyday use, Minwax Helmsman is your best finish for outdoor wood furniture. At about $59 per gallon, this oil-based finish has been protecting outdoor furniture for decades. It moves with your wood as it expands and contracts through the seasons.
Large or multiple pieces (decks, fences, multiple chairs): When you have a lot of wood to cover, Ready Seal is an epoxy lifesaver. At only $46 per gallon, this penetrating stain is designed for people who want good protection without becoming finishing experts.

2. How Much Work Do You Want to Do?

Want It Done Right the First Time: Ready Seal is your answer. This penetrating stain is called "goof-proof" for a reason, and you genuinely cannot mess it up.
Want to Work Fast: TotalBoat Halcyon (water-based) lets you apply up to 5 coats in one day. Traditional oil-based varnishes would take weeks for the same protection. At $37 per quart, it costs more than basic products, but think about your time.
Want the Best Results: If you enjoy working with your hands and want showroom results, TotalBoat Gleam (oil-based) delivers. Yes, it requires more technique and annual maintenance, but the results speak for themselves.

3. What's Your Budget for Exterior Wood Finishes?

Money's Tight ($25 — $50 per gallon): Ready Seal and Varathane Ultimate give you decent protection without breaking the bank. Ready Seal is particularly good value because it covers a lot of square footage and lasts several years.
Willing to Spend for Good Results ($50 — $75 per gallon): Minwax Helmsman hits the sweet spot here. It's been protecting outdoor furniture for decades, it's available everywhere, and it provides reliable protection for most situations.
Want the Best Money Can Buy ($100+ per gallon): TotalBoat Gleam costs more upfront but often lasts longer than cheaper alternatives. When you factor in the cost per year of protection, it's usually more economical.

How to Finish Outdoor Wood Furniture In 5 Easy Steps

After picking the best finish for outdoor wood furniture, you’ll need to know how to finish outdoor wood furniture in the right way:

Step 1: Choosing the right type of finish is the essential step to deciding the finish you want. When oil-based products give waterproof and UV wood protection, water-based products provide fast drying, no harsh smell, and a natural finish.
Step 2: Before applying, you need to clean the surface of the wood furniture with old cloths or a harsh brush to remove dust and mildew completely.
Step 3: Sanding the exterior’s surface is needed when the old surface is not smooth enough for applying, especially for old wood projects, like dining table tops or veneer table tops, etc. We advise you to use sandpaper or an orbital sander to refine the surface till it leaves no grain, and then wipe off all the remaining dust and sawdust.
Step 4: Applying the finish on your outdoor projects is the final step. You have to carefully cover all the wood project’s surface without oversaturating it.
Step 5: Everything is completed after hours of waiting and checking to make sure the outer layer is dry. Right there, just enjoy your achievement.
