How to Stain an Old Deck Using Behr DeckOver®
Wood decks unless covered are exposed to all types of weather. Rain, sun, snow, heat and cold are all harmful to the looks and life of the wood. After years of exposure wood boards begin to rot, soften, crack, warp or split. Unprotected wood is not durable when exposed to the elements. All types of sealers, stains and paints have been developed to protect wood decks. It has been my experience after many years in the painting business that all of these deck products have a limited usefulness. Why? Exposure to the sun and weather in general has a deteriorating effect on wood. This decay can only be slowed, not prevented. The deck in this project is old, I'm guessing at least ten years old. In the past it had occasionally been stained or sealed but as you can see it has become weathered and in need of restaining. A fairly new product from Behr® called DeckOver was chosen to protect this deck.
Preparing to Stain the Deck
Every paint project should begin with evaluating the surface to be painted. Reset protruding nails or screws, replace rotten boards, reattach loose boards and repair splintered boards as needed. Large cracks and holes can be filled with paintable caulk or exterior grade patching compound. Remove peeling and loose paint or stain. This can be done with scrapers or very coarse sandpaper. I have used a vibrating sander with 40 grit sandpaper as an effective tool to remove previous finishes. Almost always exterior surfaces should be washed and treated for possible mold or mildew. Behr recommends using their Behr Premium® No. 63 All-In-One Wood Cleaner prior to using DeckOver®. On this project a solution of bleach, laundry detergent and water was used to clean the deck. With either of these products or one of your choosing proper eye and body protection should be used. Thoroughly wet the surface with the cleaning solution. Using a broom or scrub brush will help loosen weak paint and better clean the deckboards. Doing small sections at a time will help maintain a wet surface. Rinse with clean water and move to the next area. Allow the deck to dry at least 24 hours or more depending on the weather before applying the DeckOver® stain.
If the previous finish is loose and peeling it should probably be stripped. One test for this, though not 100% accurate, is to apply a strip of adhesive tape to the surface and then remove it quickly. If paint or stain comes off, the bond is not very strong and the surface should most likely be stripped. It is a judgement call but the new stain's bond will only be as strong as to that which it is applied. If stripping is required Behr recommends using Behr Premium No. 64 Wood Stain and Finish Stripper® followed by No. 63 cleaner.
Primer is not required prior to using DeckOver®.
Tools to Use to Stain the Deck
Applying DeckOver® does not require any special painting tools. Using typical good quality painting tools will make the application as easy as possible. You will need a paint pot and a nylon/polyester brush for cutting in and detail work. A roller frame, roller cover, 5 gallon bucket and screen or roller tray and a roller extension will speed up the job while covering large areas. A half inch nap lambswool roller cover will hold a lot of material and washes out easily. Some type of protective material or dropcloth to cover bushes or objects not to be painted would be useful. For yourself be sure to wear suitable eye and body protection. More information about painting tools and some recommendations can be seen at The Painter's Toolbox.
When finished painting all tools can be cleaned with soap and water. DeckOver® is 100% acrylic. No solvents are needed for clean up.
Application of the Stain
Plan your work to make the job as easy as possible. Basically work from the top down then out. Typically you will paint overhead areas first then handrails and balusters then deckboards, skirtboards and steps last. Your situation may differ but it is best to plan ahead. Use the roller anywhere possible to speed up the work. “Hot Dog” rollers can be used quite effectively in tight areas. Roll a section first and then go back and finish up the missed spots with the brush. Work in small sections to keep a wet edge blending the rolled and brushed areas. If the stain is drying fast allow the rolled area to dry enough not to be tacky before brushing over it. On the deck boards start at one end of a few boards and roll to the other end keeping a wet edge as you proceed. Keeping a wet edge will prevent overlapping partially dried stain which would result in an uneven finish. With the use of an extension apply roller pressure to work the DeckOver® into as many cracks and holes as you can. It is formulated to fill gaps up to one quarter of an inch wide.
This was the first time I had used this product and having done so I think I would rather have done it on a cooler or less sunny day or wait until late in the day when the deck may have been in shade. The reason being this stain dries very fast and a longer drying time would have allowed it to soak into the surface more deeply. I think this would increase the product's ability to adhere to the surface.
These photos show a deck where DeckOver® was applied in early spring of 2014. The deck looked totally renewed. Many of the cracks caused by age and weathering were completely filled and gave the deck a uniform look. This deck stain has what looks to be very small particles in it to give it a slight textured feel and help it to be slip resistant. The texture and thickness of the stain produced a very even and attractive look. Time will tell as to its durability. As one year of use gets near we will be doing an update to this article.
