Exterior Paint vs. Stain—What's The Difference and When Should You Use Each?

Planning an exterior update is supposed to be fun and exciting. But between the different product types, finishes, and conflicting advice online, it can quickly become overwhelming.

After over 15 years painting homes across Kitchener-Waterloo, we've answered this question more times than we can count. In this post, we'll break down the difference between exterior paint vs stain, where each one belongs, and what the real cost looks like—not just what it is at the store, but also what it costs to maintain.

What's the Difference Between Paint and Stain?

	Paint	Stain
Appearance	Available in a wide variety of finishes Covers the wood grain completely	Ranges from clear, semi-transparent and solid Enhances the wood grain; solid stains will cover
Color Range	Available in any color and can be custom tinted	Natural tones Solid stains can be tinted to a wide variety of colors
Maintenance	Reapplication recommended every 3-7 years depending on surface Lots of prep work needed to maintain	Reapplication recommended every 2-5 years depending on surface Less prep work needed to maintain (if choosing clear or semi-transparent)
Breathability	Seals the wood in; does not allow for breathability	Allows the wood to breathe
Protection	Offers the best protection against UV and repels moisture*	Dependent on stain type - all stains provide protection, but clearer stains provide the least amount of protection

*While paint does offer the best protection against UV and moisture, it's important to consider the type of exterior wood you are painting. Paint does not allow the wood to breathe which is incredibly important when painting areas like decks. Ensure you read our recommendations for each surface type before making a decision.

Paint is composed of pigment and binders. The binders form a hard film on top after the paint has dried. This film sits on top of the wood and creates a seal, preventing moisture from getting in. Paint is good for UV-resistance, protection from moisture, and for covering weathered, old wood. It's available in a wide variety of colors and sheens to best suit your needs.

Stain penetrates the wood fibers with resins and oils, becoming apart of the wood itself. Stain protects the wood from moisture while still allowing it to breathe, which is different than paint. There are quite a few different stain options available, each with slightly different properties.

The Different Types of Stains

Many homeowners don't know their options when it comes to stain. There's actually quite a few with different use cases for each.

Stain Type	Protection	Appearance	Maintenance
Clear or Transparent	Least	Clear, natural	Apply every 1-2 years
Semi-Transparent	2nd least	Hint of color	Apply every 2-3 years
Semi-Solid	2nd most	Almost opaque	Apply every 2-4 years
Solid	Most	Like paint	Apply every 2-5 years

Clear or Transparent

Clear or transparent stains allow the natural grain of the wood to show through the most—there's no pigment in the stain so the full grain of the wood will be visible. Clear stain tends to impart a warm, glossy look when applied to wood. It's best suited for homeowners who have newer wood and want a completely natural look.

It does provide UV protection, although it offers the least amount of protection out of all the staining options. Clear stains need regular application, generally every 1-2 years, although the process of applying it isn't ultra high maintenance provided your deck is in good shape. A power wash, sand and reapplication and you're good to go. It's also worth noting that clear stains tend to fade the most gracefully and naturally out of all the stains.

Semi-Transparent

Semi-transparent stains are a great option for homeowners who want a hint of color while still allowing the natural grain of the wood to show through. Color choices are limited to natural wood-tones. It's best for homeowners with newer wood surfaces.

Semi-transparent stains offer more protection against UV than clear stains do, but provide less protection than semi-solid or solid stains. Semi-transparent stains tend to need reapplication once every 2-3 years. They fade more naturally than semi-solid or solid stains.

Semi-Solid

Semi-solid stains are thicker, almost paint-like stains that are nearly opaque, hiding most of the wood grain. They're available in a wider range of colors. Semi-solid stains are best for when the wood is more weathered or worn.

Semi-solid stains offer more UV protection than semi-transparent stains, as they are more opaque. Semi-solid stains will need reapplication every 2-4 years. Semi-solid stains are more maintenance than their clearer counterparts as they require more prep to reapply. This can include sanding and scraping the old peeling stain, which tends not to happen if it's a clear or semi-transparent stain.

Solid

Solid stains are the most like paint—thicker than stain, hides the wood grain completely and are opaque. The prime differentiator is that solid stains are still a stain and therefore breathable. They are available in the widest variety of colors and can be custom tinted to your needs, achieving colors that wouldn't be obtainable with staining normally.

Solid stains offer the most UV and moisture protection out of any stain, as it forms a thicker layer of protection on top as opposed to just a highly-permeable stain. However, solid stains are more likely to peel or flake away as they age. They require more maintenance in that when it's time to reapply, it will take considerably more effort to do it properly. Solid stains can last anywhere from 2-5 years in Ontario, although it's highly dependent on what surface you are staining.

Decks, or other horizontal wooden surfaces, are not recommended to be stained using solid stains as they can fail similarly to paint. In our post regarding deck staining vs. painting, we break down the benefits and drawbacks to each stain type and paint.

How Each Finish Ages

One of the most important differentiators in paint vs. stain is the way they age. Clear or semi-transparent stains tend to age much more naturally, meaning they fade away with time as opposed to peeling or flaking. Solid stains and paint tend to peel, flake or bubble up with time, especially if exposed to moisture.

This is important to consider when choosing the appropriate finish for your exterior. On average, stains require less maintenance to reapply but more frequent application. On the other hand, paint and solid stain require more maintenance to reapply but usually require less frequent application. However, it's worth noting that the application frequency highly depends on the type of surface you're painting and how much moisture it gets exposed to.

Comparing Paint vs. Stain on Exterior Wood

So now that you know each stain type and their differences, how do you begin choosing the appropriate exterior finish for your property?

First of all, paint or stain? In most cases, we would recommend stain. It's less maintenance and easier to reapply in the future.

Paint can be a good option too, especially if the area you're painting will not be affected by moisture as much (think of a vertical surface letting water run down on it, versus a horizontal one which allows water to pool on it).

If your wood is new or in good condition, it's highly advisable to go with a transparent or semi-transparent stain. If you aren't a fan of the natural wood look, try looking at the color options for semi-transparent stains and semi-solid stains. If covering the wood grain is non-negotiable, you'd be looking at solid stains or paint.

If your wood is old or worn and weathered, you'll need something that covers the wood grain enough. This could be a semi-solid stain, a solid stain, or paint. If it's a deck, always choose a semi-solid or solid stain over paint. If it's any other surface, you can choose what makes the most sense for you.

If it's a high traffic/high use area, we would recommend a clear or semi-transparent stain or a high-quality urethane enamel paint as it won't chip, peel or flake with use.

Each Surface Type & What We'd Recommend

Deck	Fence	Pergola/Gazebo	Garage Doors or Front Doors
Clear or semi-transparent stains (if the wood is in good condition) Semi-solid or solid stain (if the wood is in poor condition) Do not paint	Stain (if wood is new/looks good) Paint (if wood is older or you want the look of a painted fence)	Stain or paint (depending on desired aesthetic and wood condition)	Stain or paint (depending on desired aesthetic and wood condition)

What Paint & Staining Products We Use

For paints and stains, we primarily use two brands: Cloverdale Paint and Sherwin-Williams. Cloverdale is a Canadian, family owned company with paint that's manufactured in Canada. Sherwin-Williams is a larger brand that's typically thought of as the industry standard for their high-quality paints.

Cloverdale Paint

In terms of paint we primarily use their their Ecologic line. It's a quality paint for a great price and can be used on both interior and exterior surfaces with beautiful results.

Ecologic is self-priming and is washable and durable, making it perfect for exteriors. We use Renaissance for areas like front doors as it requires a more durable paint.

For stains, they have a line called Sharkskin which is available in translucent and solid. A great all-rounder choice.

Sherwin-Williams

For exterior, we primarily use their Emerald Exterior Acrylic Latex Paint and Emerald Urethane Trim Enamel for areas like front doors. Emerald has great application and a flawless finish. Emerald paints are a primer and paint in one. When using Emerald, we find the color coverage and payoff to be so opaque and vibrant. The washability is fantastic and the paints are durable.

For decks, we use their Superdeck Care System which includes deck wash, stain remover, brightener, stains and sealants. A great product line for anyone looking to update their deck.

Paint or Stain? Here’s the Bottom Line

Choosing between exterior paint and stain comes down to the surface you’re working with, the condition of the wood, the look you want, and how much maintenance you’re comfortable with in the future.

For most exterior wood surfaces, stain is usually the better long-term choice because it allows the wood to breathe and is easier to maintain when it’s time to reapply.

Clear and semi-transparent stains are best for newer wood where you want the natural grain to show through, while semi-solid and solid stains can help give older or more weathered wood a more finished appearance.

Paint can still be a great option for certain vertical surfaces, trim, doors, fences, and areas where you want full color coverage—but it needs the right prep and the right surface to perform well.

The most important thing is choosing a finish that suits both your home and the way that surface will be used. A deck, fence, pergola, front door, and garage door all deal with weather, moisture, and wear differently, so there isn’t one perfect answer for every project.

If you’re still not sure whether paint or stain is the right choice for your exterior wood, we’d be happy to take a look and give you honest recommendations based on your home, your goals, and the condition of the surface.
