I have been applying Sherwin-Williams products for years. I am impressed with the company’s commitment to quality in its products. While I can give an unqualified recommendation for many of their paint products, their exterior stains have some limitations. Keep reading to get my take on Superdeck oil-based stain.
Superdeck Detailed Overview
Superdeck transparent and semi-transparent are exterior oil-based stains created by Sherwin Williams. This company has been making paint and other coatings for over 150 years. This product is meant for protecting outdoor wood structures like fences, decks, and siding. It can be applied to any bare wood that is on the exterior of your home.
This product comes in transparent or semi-transparent color options. The transparent version will allow more of the wood grain to show through. It is used to enhance the look of new wood.
The Semi-transparent colors will cover up more of the wood while still allowing some grain to show through. This option gives by far the most color choices for you.
The oils in Superdeck will repel moisture from your wood to protect it from rotting. Warping is also caused by moisture so this product can help prevent that also. The pigments used in the stain offer protection from UV rays which will break down wood over time.

Ease of Application
Superdeck is a standard oil-based stain. If you are familiar with applying wood stains the application process will be similar to other products you have used. One difference is that Superdeck can be applied in one coat only. The manufacturer recommends against applying a second coat.
The reason it can only be applied with one coat is that the product forms a clear film on the surface of the wood. This film will keep any additional coats of stain from penetrating into the wood. The subsequent coats will also have a tendency to peel because they do not stick to the film well.
Care must be taken when using this product to keep a wet edge. This means that you should not allow the stain to dry in the area you are working on. If you apply new stain over a dry area, the place where they overlap will be darker than the others.
If you are applying this product with a sprayer, you should make sure to back brush the wood. This will promote penetration and an even coat. Your stain job will last longer and look better.
Application methods: Brush, roller, pump sprayer, airless sprayer
Requires back brushing: Yes
Requires keeping a wet edge: Yes
Superdeck can be inconsistent with its initial appearance. Sometimes it will look great when first applied. I have also seen times when the color is uneven. Because this product can only be applied in one coat you don’t have the option of adding a second coat to help even out the color.
The surface film that this product creates gives the surface a little bit of a sheen. Most other outdoor stains have a flat appearance. This makes Superdeck’s colors seem a bit more lustrous and deep when they are first put on. This will be true for about a year until the film wears off.
Superdeck is a hybrid product that will penetrate into the wood and form a film on the surface.
Superdeck comes with a high price tag like many other products from Sherwin-Williams. Sherwin Williams often runs sales so you might be able to get it at a lower price if you time it right.
Ease of Reapplication
The surface film on Superdeck must be allowed to naturally wear off or should be physically removed prior to applying a new coat of the stain. According to the rep with Sherwin Williams that I spoke with, the film should wear off in about a year. Otherwise, the reapplication process can proceed the same way as the initial application.
The fence should be cleaned before a new coat of stain is put on it. If there is gray on the fence this will need to be chemically treated prior to staining.
Resistance to Peeling
Because Superdeck forms a surface film, it will have a possibility of peeling. This is especially true if a second coat is applied.
