How To Clean A Wood Deck Before Staining

Even if your deck is fabricated of force per unit area-treated lumber, redwood, cedar, or some other durable species, it's at risk the moment the last nail is driven habitation. There are several culprits. Moisture swells the wood while the burning rays from the sun dry and compress it, causing cracks and checks while as well encouraging warping. Ultraviolet rays as well discolor wood and accelerate wear past breaking downward wood fibers.

Add in the scratches that occur when you drag chairs beyond the surface, splattered grease from barbecues, mold growth in shady spots, and ground-in dirt from foot traffic, and near decks start to look old within a few years.

Reversing the harm is simple enough. Apply a specially formulated cleaner and and then treat the surface with a h2o-repellent end. It'south a systems approach where all the elements piece of work together. Dirty decks won't accept a finish well; clay can also react with the finish and turn the lumber blackness. And even the cleanest deck surface is at the mercy of the elements without the right finish.

Choosing from among the several hundred deck cleaners, stains, and sealers out there is less unproblematic. You lot'll also have to decide whether to do the job yourself or hire a pro. Here's how to take the guesswork out of renewing a worn deck or protecting the i y'all just congenital.

Fourth dimension, Cost and Materials

Most homeowners practise the work themselves considering they can salvage money. The materials for a 20x20-foot deck will run betwixt $80 and $120, plus another $fourscore or and then to rent a ability washer for a day. What's more than, the actual work takes only two days — ane to clean the surface and some other to apply the terminate. Merely y'all will take to wait three to five days after cleaning for the deck to dry so the end volition penetrate fully.

If you don't have the time to practice it yourself, you can hire a deck-maintenance contractor. Just the relative newness of this specialty means about of the pros don't have much experience. That makes checking references and visiting past jobs specially crucial. And because most pros take their favorite products, y'all'll probably have picayune say most the ones used on your deck. Expect to pay between 60 cents and $one per foursquare pes for materials and labor — up to $400 for a 20x20-human foot deck.

Best Deck Cleaner

Deck cleaners get rid of mold, mildew, and whatsoever dirt or stains imbedded in forest fibers. Though you can mix your own with laundry detergent and bleach, a store-bought cleaner is best for very muddied or damaged wood.

These products fall into two categories: cleaners and restorers. Among the leading makers are Thompson's, Wolman, and ZAR. Cleaners comprise detergent and bleach and piece of work best on dirt and mildew. Restorers comprise oxalic acid and are ideal for removing tannin streaks and stains around boom- and screwheads in cedar and redwood decks. Both come in liquid and crystal form and cost about $fifteen for enough to brand 5 gallons of solution (adept for 750 to i,000 foursquare feet of deck expanse).

If your deck was painted or sealed with varnish (a big mistake), you'll need to remove these high-maintenance finishes with a deck stripper before cleaning. Whether you use a stripper or woods cleaner, or both, apply information technology with a roller or stiff-bristle button broom. Wait a few minutes for the production to soak in. So rinse with a hose or power washer. Remember to clean the exposed ends of cut deck boards.

Color PIGMENTS in semitransparent and solid-color finishes help protect wood from UV rays. Use finishes designed for decks; products meant for siding won't stand up to foot traffic.

Best Deck Sealers & Stains

Deck finishes fall into two categories: sealers and stains. Both are formulated to seal out the elements. As their name implies, clear sealers are nonpigmented finishes. Stains are available with a little pigmentation (referred to on the label as "tone"), semitransparent, and in solid colors. Unlike paints, which form a surface film, articulate and pigmented finishes penetrate the wood and can stand up to human foot traffic.

"The ideal deck end does iii things," says Charles Jourdain, vice president of technical services at the California Redwood Association, a lumber-industry trade grouping. "It repels water, preserves the wood with a mildewcide, and screens out UV rays." Some products waterproof but. For maximum protection, the label should list all three features.

Oil- or water-based finish?

Deck finishes are either oil- or water-based. Which you choose depends on your priorities. According to Mark Knaebe, a pharmacist with the U.S. Department of Agriculture Forest Products Laboratory who evaluates deck finishes, oil-based finishes provide more and longer-lasting protection. "Oil-based finishes penetrate deeper into the forest than water-based finishes," Knaebe says. Familiar names here include Cabot'due south, DAP, Inundation, Olympic, Thompson's, and Wolman.

On the other mitt, water-based products are easier to clean upward than oil-based products. They're also more than forgiving in damp weather condition, explains deck-maintenance contractor John Sundquist, of Northbrook, Illinois, based American Deck Maintenance: "While the forest surface must be bone-dry before it accepts an oil-based sealer, damp wood can absorb a water-based product." H2o-based finishes also final longer than they did just a few years ago. Companies like Wolman and American Building Restoration Products (X-100 Natural Seal) brand a water-based version of their product.

Clear or color finishes?

Clear deck finishes are popular considering they allow the natural grain of the wood to prove through. And considering they're transparent, you tin can't get out whatever lap marks during application, which is a common problem with pigmented finishes. But, they aren't as skilful at blocking UV rays.

The best UV protection comes from a combination of chemical inhibitors and colour pigments. Though inhibitors in some articulate finishes ho-hum UV penetration, they tend to intermission down relatively chop-chop. The result is that about must be reapplied yearly.

Lightly pigmented and semitransparent finishes add color to the deck while assuasive some of the grain to show through; they too form an constructive UV barrier. The more pigment the finish has, the improve it is at blocking UV rays. That's why a semitransparent deck finish will concluding up to iii years or more earlier another awarding is needed.

Solid-color finishes offer the most UV protection. Unfortunately, most aren't formulated for foot traffic. If you want a solid color, look for products fabricated expressly for deck surfaces, such as Cabot's solid-color decking stain with Teflon.

For do-information technology-yourselfers, at that place are 2 drawbacks to pigmented finishes. They leave lap marks or areas where the terminate is uneven if y'all don't apply them carefully. They besides prove traffic patterns as they wear, which requires spreading actress finish into affected areas during reapplication.

Figure on spending $15 to $25 per gallon for a good clear or pigmented deck finish. Finishes that cost less probably won't provide all of the protection your deck needs.

HEAVILY SHADED DECKS are prone to mildew. After initial cleaning and finishing, apply a deck cleaner annually to help proceed mildew at bay. Make sure the finish y'all employ contains a mildewcide.

How to Utilize Deck Stain & Sealer

Waiting nine months to a year before applying cease to a new pressure-treated-woods deck used to be standard process. Leaving woods unprotected lowers the interior moisture content and allows the pores to open and accept more sealer or stain. Unfortunately, information technology likewise contributes to weathering.

Instead, utilize finish on a new or newly cleaned deck within a few weeks. Then apply a second coat the following twelvemonth. "That second application leaves more finish in the wood. Doing information technology right as well lets y'all wait two or three years before putting on another coat," says the USDA's Knaebe.

The one exception to finishing correct abroad is new lumber that has a waxy buildup. This factory glaze won't permit the finish to penetrate and whatsoever finish applied to information technology will peel off in a few months. You'll know information technology's there if water from a hose beads on the surface. Mill glaze can too appear as a burnished expanse. In either case, wait two or three weeks and then the surface can weather. If h2o still chaplet up, sand lightly.

Apply the stop when the temperature is above 50°F and the weather will exist dry for a few days. Follow directions; these tips apply to all products:

• Wear eye protection and long pants and sleeves. Also wear rubber gloves, specially when using a stripper.
• Before applying a finish or cleaner, protect surrounding vegetation past wetting it with a hose and covering it with plastic tarps. Rinse again when washed.
• Cease the top, exposed sides and — on new decks — the bottom of boards, if possible. Also coat any structural members you can attain. Futurity maintenance can concentrate on surfaces and end grain exposed to the atmospheric condition.

Relaxing on a deck is a great way to savor the outdoors. The right care will prolong your enjoyment by protecting the surface of the wood for years to come.

FINISHES WITH slight pigmentation provide natural beauty and let you avoid lap marks. Look for "tone" on the label.
