Wood siding treatment is an extremely vial procedure as far as maintaining the appearance and enhancing the durability of your exterior design is concerned.

Painting and staining are the two techniques that are commonly utilized to treat wood siding. Painting is generally considered the harder option even though it should only be done once in 10 years.

It is however known to be a much easier alternative to painting despite its higher frequency of application. This is mainly because of the similarity that exists between the previous coating and the current staining process.

How to Treat Wood Siding


The following are the steps to follow when looking to properly prepare your wood siding for painting:


Power Washing

Power washing in this case refers to the removal of any siding flaws that may have occurred as a result of the collecting together of substances such as loose paint, mildew, grime and mud among many others.

It is usually done so as to enable the new coating to effectively cling onto the wooden surface in question. It should therefore be thoroughly done before the application of any form of paint on the siding.


Repair any Spoilt Areas

Any joints that are vulnerable to water should be caulked using either silicone or polyurethane filling before commencing the painting. Vinyl spackling may also be used in which case it must be applied in two even coatings and allowed to dry.

This caulking is generally known to aid in preventing any potential water leaks as well as ensuring the better application of paint. The replacement of any areas in the wooden siding which have been damaged beyond repair should also be done.

It is also important to smoothen any areas which may have been patched as a result of any previous spackling. Any rough areas on the edges can equally be straightened out through this sanding process.


Surface Priming

Priming the siding is usually done in order to create a basis through which quality finishing can be obtained. It should thus be done using a primer which not only matches the color of the paint but also is tinted a little lighter than the paint in question.

There sometimes may be need to apply multiple layers of primer coats so as to ensure that the wood is completely saturated and covered. In such cases, each layer of prime paint should be allowed to independently dry before the application of another coating.


Actual Paint Application

The actual paint application is perhaps the most vital stage as far as the appearance of your exterior wood siding is concerned. Roller painting is normally recommended when one is doing the painting themselves even though it is quite time-consuming.

This is because faster methods such as spray painting are usually considered to be effective in obtaining an even coating when engaged by painting experts. Brushing is also recommended when looking to paint around door and window openings.

Whichever method one chooses, one should ensure that the paint coating on the sliding is thick enough in order to achieve a long-lasting effect. Previous coatings should however be allowed to dry first before applying subsequent ones.


Pros and cons of painting

Painting is generally known to create a thicker layer of coating when compared to staining. Paints also come in a variety of colors which means that they can cover almost everyone’s aesthetic appeal while providing long-term protection.

Timing must however be considered when one decides to go the painting route. This is because it can only be done effectively under relatively warm conditions. It is also advisable to leave painting to professionals even though this might be more expensive when compared to DIY painting.


The steps to be followed as far as the staining of exterior wood siding is concerned include:


Surface Cleaning

Thoroughly clean your exterior siding using a power washer then apply a coating of bleach on it. Clean out the bleach as per the instructions using the pressure washer and then wait for the said surface to completely dry out.

The drying may take a few days but it is well worth the wait when looking to guarantee a long lifespan for the stain.



Caulking in this case is simply filling in the gaps to prevent any water penetration. This is mostly done on any water or moisture-vulnerable joints.



The stain chosen should ideally match one’s desired appeal. The only way to guarantee this however is through a spot check. Brushing in the stain is usually the preferred method as far as achieving a highly protective and durable seal is concerned.

It is also important to avoid applying the stain under direct sunlight lest any kind of patching begins to occur.


Pros and cons of staining

Staining is an easier process to carry out yourself since it does not require a priming step. It can however result in a low-quality siding when done either on moist siding or under direct sunlight.
