What is the Best Deck Stain?
This is the most popular question that deck owners have. Unfortunately, there is not a “best” deck stain out there. There are products that are better than others, but there is not one that will outperform every other stain.
A better way to approach this common question is to ask, “what is the best stain for my deck and it’s environment”? Just because a deck stain performs well in the Northeast part of the country does not mean it will perform well in the high altitudes of Arizona. There are also VOC (Volatile Organic Compounds) Laws the come into effect for different parts of the country. This may limit what is available in your state. For example, TWP 100 Series cannot be used in 17 states that have a low VOC content of 250.
To understand a deck stain and its potential longevity, we should first look at the main reasons deck stains fail:
- UV rays from the sun will damage the wood resulting in degradation of the wood cell structure. This will break down the stain while causing the wood to oxidize (turn gray).
- Water, snow, and ice will cause damage to the wood by breaking down the exposed cellular structure.
- Freeze/thaw will expand and contract the wood resulting in the stain “bond” with the wood cells to fail.
- Mold, mildew, and algae will leave the wood unsightly/dirty and can result in rotting.
- High traffic areas will leave “wearing” patterns.
- The previous stain used was of low quality or applied poorly.
- The Stain was not applied properly or the wood was not prepped properly prior to application. Bad prep is the number one reason stains prematurely fail!
What is the Best Deck Stains?
Once we figure out the main reasons for failure, then we should research what stains would work well for your deck. This is the difficult part, so let us get started!
We will ask a series of 5 questions. Based on these answers (Answers are in Red) we will narrow the choices to 2-3 stain brands that will work at maximum performance for your deck:
Here is an example deck:
- Deck Location State: New York
- Full Sun, Partial Shade, Full Shade: Full Sun
- Wood Type: Pressure Treated Pine
- Mold or Mildew Issues: Yes
- Reason for Previous Stain Failure: Peeled and turned dark in color
- Previous Stain Brand and Type of stain (Solid, Semi-transparent, Transparent, etc): Penofin Sem-Trans
First of all the state of New York is a low 250 VOC state. This limits the stains that can be purchased or sold legally. Many decks stains that are of low VOC have been known to fail faster than a 550 VOC stain. There are still quality stains available, just not as many. The rest is fairly easy to figure out. This deck should use a 100% penetrating stain that does well with UV protection and is not prone to mold/mildew growth. A semi-transparent stain that fades evenly over time with little to no wearing. This makes future maintenance easier.
Based on these questions and answers we would suggest one of these stains:
