Exterior stains are formulated to offer superior protection of the wood surface while enhancing the texture and grain, in order to exemplify the beauty of the wood itself.

Different surfaces will require distinctly different characteristics from an exterior coating. A large mass of wood such as a log naturally retains more moisture than a 2×4 – which means it will decay unless the wood can breathe.
A deck needs more water repellency and UV protection than a wall due to the direct angle of UV rays. You will want to make certain that you invest in products designed to offer the best protection and performance depending on the characteristics of the wood surface you are coating. Please ask the questions as your result for longevity is integral.
It is extremely important to inspect wood surfaces for defects and make any necessary repairs prior to finishing. There are available to you specially formulated cleaners and/or wash the entire surface with a pressure washer using clean water. You should always sand the surface as well using a 60-80 grit sandpaper and a variable speed orbital sander. This allows the grain of the wood to be open and accepting of the product you will be applying. Follow by lightly washing once again, vacuuming or using compressed air for proper cleaning and allow to dry thoroughly prior to any application of product. Surface must be clean, free from dust, dirt, grease, wax or any existing coatings. Now you are ready to apply your protective coating.

You will also want to remember when applying any exterior product to not apply in direct sunlight nor on a hot surface, as it will set to fast and not allow for proper penetration.

Remember when purchasing product that different stains are specifically formulated for horizontal surfaces and for vertical surfaces. Please make sure you ask which products are for the surface you are coating and which will perform the best. Proper preparation will lead to the beauty and longevity of your final look.
Breathability, ease of maintenance and sustainability is most important when protecting your exterior wood.
