Scrub the fence with a wood cleaning detergent or a 20-percent solution of chlorine bleach that contains 1 part bleach and 4 parts water. Spray the fence with a garden hose and use a long-handled scrub brush to scrub the pickets from top to bottom, paying particular attention to the mold, mildew and algae.
The best way to restore your cedar siding or cedar fence to its original glory is with soft washing. Instead of the robust streams of high-pressure water used in pressure washing, soft washing uses a low-pressure technique with a special mixture of highly effective and biodegradable cleaning solutions.
Wood rot occurs when water once again hits these dead cells. The combination of water and UV exposure causes the cedar to lose it's scent and colour, turning it into a dull grey. The wood rot on the cedar creates an ideal breeding ground for mold and mildew, which is both unattractive and detrimental.
Sand small areas of wood with sandpaper and a sanding block or large sections of wood with an electric sander. Use coarse sandpaper and continue to sand until all the grey is buffed from the surface of the wood.
Once cedar has turned gray, there is no natural way of going back. The only alternative at this point is to tone the wood with a stain or other coloring agent. Maintaining your cedar's color is about choices, timing, and above all, the right type of treatment.
Cleaning. If your siding's fresh color lays buried under a gray, weathered surface and mold, buy a bleach-based cleaning solution or mix 3/4-cup of bleach with 1-gallon of water to restore or salvage the cedar's luster.
Lots of manufacturers make gray stain without using a steel wool and vinegar stain. We used Benjamin Moore Arborcoat. It's made for exterior use and it is stinky until it dries, but it gives a beautiful silvery sheen to both cedar and pine.
Allow the washed surface to dry before recoating and apply primer paint to areas of bare wood. After the primer has dried, apply one or two topcoats of paint or solid-color stain. Two topcoats are always better over bare wood that has been primed. These may be applied to Western Red Cedar by brush, roller, or pad.
Boiled linseed oil, despite not providing much water-resistance to wood when applied in the usual way associated with furniture, will do much to slow the weathering to that natural grey/silver colour if applied heavily and re-applied periodically.
One part white vinegar to 3 or 4 parts water is fine. Dip a sponge in the vinegar solution, and wipe it on the bleached wood. Rinse the sponge in clear water before dipping it again in the neutralizing solution. Once the cedar is dry, you can leave it as is or apply the finish of your choice.
Mix the powdered Oxiclean as four parts water to one part powdered product and apply the solution with a garden sprayer. All the OxiClean to soak into the wood for around fifteen minutes. Once the time is up, you can use a soft-bristled scrub brush to remove the debris, followed by a rinse-off with the garden hose.
Staining Old Cedar:
If a few steps are performed, staining an old cedar siding comes out almost flawlessly. You should always remove all old flaking paint or stains on the top layer of wood by using power washing.
Sometimes its as early as 2 months, and other times it takes a year for the grey to set in. This is why stain is so necessary for your cedar wood. It keeps out the water, so those cells can keep doing their thing. But remember: Once your fence is installed, it can't be treated right away.
Tung oil works perfectly on Cedar wood.
it works as a protective layer while giving a dark rich look to the Cedar wood furniture and woodworks.
Cedar should be stained as soon as it will accept the stain. This is easy to determine with penetrating semi-transparent stains. Apply the stain, if it soaks in its ready. If it pools on the surface, do it later.
Rinse your siding with water. Make sure to rinse away all bleach, because any bleach left behind may discolor the cedar.
The best woods for bleaching include oak, beach, ash, and gum. Varieties like poplar and pine are already so light that removing further natural wood color might render them bland and lifeless. Others, like cedar, redwood, rosewood, and cherry don't take bleach well.
Yes you can paint the gutters. Have the painters spray them. The cedar can be stained with a semi-transparent or opaque stain.
The answer is, Yes, linseed oil is one the most recommended finishes for cedar woods. For a reason that it thrives on humid weather and reduces the sunlight damage. Ideally suited for patio furniture as they need extra care from weather, so it is an ideal solution.
There are two oil finishes recommended for sealing cedar: teak and linseed. Applied the same way, teak and cedar oils produce a similar protective finish with a warm, hand-rubbed, natural-looking appearance as compared to varnish and urethane.
Used to preserve the Cedar's natural color and appearance, transparent or semi-transparent solvent-borne penetrating stains are recommended. Transparent stains are similar in composition to semi-transparent stains but contain fewer pigments that provide color.
Prime. Natural woods like cedar must be primed before they are painted, or the paint will have trouble adhering. Cedar is notorious for its tannins — the sap that seeps through the paint — and this seeping can lead to ugly stains that expose themselves even through layers of paint.
