How to stain exterior cedar siding

The way that you prepare your cedar is going to depend on what age it is. If the cedar is quite old then you need to look for any defects in the wood such as rot and mildew.

If it does, then you’ll need to clean these contaminants off with a dedicated solution. You’ll also want to check to see if it has a chalky texture or if there is any cedar bleed and these will need to be separately dealt with.

For new cedar, you’ll probably want to sand it a little so that you get a better adhesion from the stain. If the cedar is clean-textured then it’s not going to need any preparation.

Before staining, you’ll want to ensure that there isn’t any sawdust left on the wood as this will negatively affect the finish and you may not get an even stain.

Before you start staining, it’s a good idea to protect the surrounding areas as much as you can from drips. This is going to be more important if you’re using an oil-based stain as it’s not going to be as kind to the environment as a water-based stain.

Ideally, you should stain when it’s not too hot but when the wood is as dry as possible. It’s usually best to do it either early in the morning or the evening when the sun isn’t beating down on it. Depending on your climate this isn’t always possible and some stains can even be applied on damp wood.

A brush, roller or spray can be used to apply the stain. A brush is probably the best for deep penetration but takes the longest to apply. Using a sprayer won’t give the same level of penetration but is a much faster means of application.

Once you’ve applied it when it will need to dry. Often you won’t get the full effect of the stain until up to a couple of weeks afterward. Once you’ve finished then ensure you do a full clean-up of the area to give it that professional finish.

Why you should get the exterior stain

There are many reasons why getting the best exterior stain for cedar siding is a good idea. Perhaps the most obvious is that it’s going to protect the wood and keep it looking its best for years to come.

Without protection, the siding will start to develop issues a lot sooner.

Key features of exterior stain for cedar siding

Finish

There are different types of stain that you can get all the way from completely clear to a solid color. It’s therefore important to know what you are looking for before you get started.

Do you want to enhance the existing color or get a completely different look? Here we’ll take a closer look at these types to see which one would be the best option for you.

Clear: When people think of stain they usually associate it with changing the color a little bit at least. There are, however, clear stains out there which work more or less as sealants. They can give you that extra level of protection whilst retaining the original look of your cedar. It’s ideal for those who don’t want a color change at all.

Transparent: It’s important to check exactly what is being offered with the transparent stain as some of them are clear whereas others will have a slight shade to them. What they do have in common is showing the natural beauty of the grain beneath the wood. It’s ideal for those who want the benefits of stain but with a minimal color change.

Translucent: This is a thicker color solution but one where you’ll still be able to make out the grain underneath. It’s ideal for those who want to significantly change the color of the siding while still showing off the wood below. It generally has a higher level of protection than either a clear or transparent stain.

Solid color: A solid stain option pretty much acts like paint and will completely cover the wood with the grain no longer being visible. This is for anyone that wants a complete change to the natural color of cedar. This gives you the maximum protection but is often the hardest material to work with as it’s a little thicker than the other options.

Water or oil-based

You’ll see that stains either come as water-based or oil-based but what’s the difference and which one should you choose?

Well, the decision is up to you but here we look at the key differences.

Water-based: This type of stain is going to be better for the environment and you don’t have to worry about it dripping into your soil or onto your plants. It’s also very easy to work with as it’s thinner and can therefore be used with a sprayer.

Oil-based: Some people prefer to work with oil-based stains as they are better at penetrating the wood. They can be a little harder to apply with many not suitable for use with a sprayer. They also can be quite harmful to the environment so you need to be more careful.

Coverage area

You don’t want to get 90% of the way through staining your sidings only to realize that you’ve run out of stain. Having a long delay can mean that your stain may not dry evenly which leads to results that are far less than perfect.

The exact amount will vary from one stain to the next but on average, a gallon of stain is going to cover an area of 200-300 square feet. It’s best to get a rough idea of the area your sidings cover before you get to work on staining it.

You also need to know how many coats you’re going to need. Many stains will only need one coat which can be easier on your budget. If you’re changing the color significantly then you may need more than one, and therefore a lot more stain.

Protection

Perhaps the main reason to use stain is to protect the wood underneath. The level of protection you get is going to change due to a few different factors. Most will also act as a sealant and it can be great to have that 2-in-1 solution.

Knowing the climate you’re in can also affect your buying decision. If you live in a harsh environment then you may opt for a darker stain as this will wear away more slowly. It can have you from constantly needing to maintain your siding.

As a general rule, darker stains will offer more protection than lighter stains. That’s because their increased number of pigments increase UV protection. Some people don’t like darker stains and will therefore accept less protection from a lighter one.

Color

The stain is most likely going to change the color of the wood so you need to think of which color is going to be best suited to your needs. Most stains have a color that is meant to reflect another type of wood so you can make your cedar look like redwood, for example.

Cedar can come in a few different shades but is often quite light in color. It can be quite beautiful in just that natural shade and therefore a lot of people like the idea of simply keeping it as it is. Others will look for a different color and there are a lot of different options available.

The Ready Seal stain gives you quite a few different options. Cedar is a fairly light wood but you may even choose to go a little lighter and opt for a golden pine or a light oak that can brighten up those exterior sidings.

You can also go the other way and opt for something much darker and give your sidings a much warmer feel. The likes of mahogany, burnt hickory and dark walnut are all examples of stains that will give your cedar siding a dramatically different appearance.

When looking at solid color and semi-transparent stains, you usually have the opportunity to change the color to something completely unnatural. The Deft stain gives you the option of going for a Driftwood Grey along with its more natural range.

The decision that you make will ultimately be up to you. There are plenty of options out there for you and you’ll have an idea of which one is going to be most suited to your cedar siding. All of the four stains we’ve looked at here have a range of colors.

It’s worth noting at if you wanted to have a dramatic change of color then you may need to apply multiple coats and be more patient about the results. This can be more of a factor when moving from dark to light and you should factor this into your buying decision.

Application

You need to know how you’re going to get your stain onto your cedar siding.

You generally have three options of either a sprayer, brush or roller. Here we look at the pros and cons of each option.

Sprayer: This is usually the easiest and fastest method of application. It’s great for wide areas where you can cover them quickly. They lack accuracy though which is why it’s usually a good idea to also sue a brush in the more delicate areas. A sprayer is sometimes not an option for thicker stains which may struggle to get through the nozzle.

Brush: This is going to be the most accurate method and the one that will be best for getting the stain deeper into the wood. Using a brush will also give you precise control over how much stain you use with the minimum of mess. The downside to brushing is that it will take the most time.

Roller: As with the sprayer, this can be a quick and efficient solution and one that can give you a bit more control. It can still be a little messy so you do need to be careful. It’s great at giving you an even coat and it can work with all types of stain and is, therefore, a good idea if you’re using a thicker solution.

Frequently Asked Questions

Do you have to remove the old stain before re-staining?


This is going to depend on a few different factors such as the condition of the existing stain. If you wanted the best results then it’s usually a good idea to remove the old stain before you get started. This is especially important if the old stain is peeling and worn out.

If the old stain is still well adhered to the surface then you may get away with staining over the top of it. If you are getting a new stain then it’s good to apply a maintenance coat fairly often as this will prevent you from a much large stripping job in the future.

Whether you need to strip will also depend on whether or not you want to change the color. A semi-transparent stain, for example, isn’t going to adhere well to the siding which has previously received a solid stain. If you’re making a big change then you’ll need to remove the old stain.

Is it better to paint or stain cedar siding?


The first question you need to ask is whether or not you want to see the grain of the wood. If you do, then paint is not going to be an option and you should either opt for either a transparent or semi-transparent stain.

If you are deciding between a solid color stain or paint then there are a few things to consider. The stain is easier to apply than paint and you often only need one coat. It’s also easier to maintain as you can apply a new coat with minimal preparation.

Paint can be harder to apply but often gives more protection as it will completely lock out any water and block UV rays. While paint often lasts longer, it requires more of an effort to repaint when it’s time to maintain your siding.

There is then no right or wrong answer here. It’s about what you’d prefer and many like how easy staining is. Others prefer the finish and greater level of protection that you can get from a high-quality paint.

How often should cedar siding be stained?


The exact answer to this question will depend on what the siding needs to cope with in terms of the weather. If the hot sun is constantly beating down on it then it will need to be stained more frequently than a home which is often in the shade.

There are some key signs to look out for which show when a siding should be stained again. These include water starting to be absorbed into the surface, you see that the wood is damaged in any way and also if the stain appears to be faded.

It’s usually between 3-5 years when you’ll need to apply another coat of stain. It’s a good idea to give it an inspection every year to see how it’s holding up.  If you live in a harsh environment then you may need to apply a new cost more frequently.

Is semi-transparent or solid stain better?


There isn’t one right answer here as both of them offer different things. A solid stain is going to have more pigments and therefore give you more protection from UV light. It’s also better if you wanted to completely cover the grain.

If you wanted to still see the wood grain and have that more traditional look then you’re going to want either a transparent or semi-transparent stain. They don’t quite have the same level of protection but will still last for a few years and are easy to reapply.

How long does exterior stain last?


The more pigment a stain has, the longer it’s going to last. This is the reason that a solid stain would last longer than a clear stain. The longevity of a stain will also depend on its exposure to the weather and other factors.

Stain on a garden bench, for example, isn’t going to last for as long as on a siding. That’s because it will be in contact with more direct sunlight, have water sitting on it and also there is that fact people will be sitting on it.

Stain on cedar siding probably lasts for around 4 years, on average. On decking and furniture, it’s going to be a little less. As we’ve mentioned, this can depend on a few different factors and therefore regular inspections are a good idea.

How do you prepare old cedar siding for staining?


The first thing you need to do is to inspect the siding to see how much preparation is required. This can start with a visual inspection to see if there is any rot forming or whether there are other contaminants such as mildew or chalking.

One easy test to see if the old stain needs stripping is to use a strong piece of tape. Place it over any part of the siding and then rip it off. If you have any old stain on the tape then it’s a good indicator that it’s not doing its job and now needs to be replaced.

If there are any contaminants on the wood then these need to be dealt with separately. Mildew requires a strong cleaning solution, chalkiness needs a detergent wash and cedar bleed needs its solution to stop it from being a future problem.

Trying to stain with any of these issues present isn’t going to lead to great results. To finally prepare your siding for stain then you’ll need to either sand it down or scrape off any problem areas. Another solution is to pressure wash it, which can be a lot quicker.

Cedar siding maintenance tips

Once you have a good stain on your siding, maintenance should be fairly easy. Ideally, you should try and keep moisture away from it which includes not having any plants or branches touching the siding which can be a constant source of moisture and scratch off the surface.

Along with applying a new coat every few years, you should regularly clean your siding to ensure that dust and dirt don’t accumulate on it. Pressure washing can be a good idea but you can just use a soap and water solution.

Regular inspections are also recommended. This will show you if there is an issue with any with the wood or if you have any spots where the stain is quickly fading away. You’ll also be able to see if there’s an issue with the likes of termites or woodpeckers.

Final Thoughts

Hopefully, by now, you have a clear idea of exactly which stain would be the best one for you. The four we have selected have all been carefully chosen for delivering an excellent level of protection while also giving a brilliant finish.
