I have applied TWP to my customer’s decks with good results. I have seen firsthand how TWP can keep a fence looking good for years.
Note: TWP 100 series is not available in every state because of VOC regulations. If you live in a state that requires low VOC products you should consider TWP 1500 series

TWP or Total Wood Preservative is an oil-based fence and deck stain manufactured by Gemini Coatings. It is intended to prolong the life of exterior wood. In addition to fences and decks, it can be used on outdoor furniture, siding, and gazebos.
The Product uses high-quality trans-oxide pigments that block UV rays that can damage exterior lumber over time. It’s oil base is made to fully penetrate into wood to keep moisture out. This will protect against both rotting and warping.

Ease of Application
TWP is a standard oil-based stain and requires the use of best practices to get good results. This includes applying the stain in an even coat, back brushing if you are spraying, and keeping a wet edge while you stain. If these steps are followed you should get an even color and a finish that will protect your wood.
One thing I have noticed when applying TWP is that it dries quickly on your hands and equipment. When it does it starts to feel really sticky. I recommend wearing gloves when using this product to keep it off your skin. Also, make sure to clean any tools you are using with mineral spirits. The sooner you clean them, the easier it will be to get the stain off.
Application methods: Brush, Roller, Pump Sprayer, Sprayer
Requires back brushing: Yes
Requires keeping a wet edge: Yes
TWP offers eight transparent colors for their stain. This means that the stain will highlight wood grain in new wood. The colors range from a light natural wood look to dark oak. They also have interesting gray colors called Cape Cod gray and prairie gray.
If you have older wood that needs to be covered up you can select one of their darker colors like dark oak. The lighter colors may show too much of the underlying wood in this situation.
When applied correctly, TWP has a flat appearance and should have minimal sheen.
TWP is intended to fully penetrate the wood. This means care must be taken during application to remove any excess product. Any stain that dried without penetrating the wood will result in a shiny spot that is prone to peeling.
This stain tends to cost a little higher than average for exterior oil-based stains. It offers good value for the price.
Ease of Reapplication
TWP recommends applying a new coat of stain when the color starts to fade (usually 12-24 months). Applying a new coat of TWP required that the fence be cleaned first. This can be done by lightly cleaning the wood with a power washer.
After the fence is dry, a new application can proceed in the same way the first coat was applied. TWP does not require you to remove an old coat of the same product before you apply their stain. If a different stain brand was put on first, it will need to be removed completely before you apply TWP
If applied correctly, TWP should not have any issues with peeling. The stain should fully penetrate the wood. Make sure to wipe off any excess stain during the application process.
