How do you keep cedar from turning GREY?

Treating Cedar With a Bleaching Oil
First, the oil tones the wood with a light gray pigment to fix the color. Second, over a short period of time, the oil will accelerate the bleaching process so that you get the weathered look faster and more uniformly applied.

Does cedar wood need to be sealed?

When to Seal Cedar Siding
That being said, if you have a smooth cedar plank construction like in the picture above, you should still be able to seal safely. Cedar has a natural tendency to dry quickly and resist moisture (with proper ventilation) so other pre-installed siding can also still be sealed or painted.

What is the best finish for red cedar?

semi-transparent stains
These finishes are the best choice for Western Red Cedar, which is fully exposed to the weather, when a natural look is desired. Although these stains can be used on both smooth and textured Western Red Cedar, they will perform much better and last longer when applied to a textured surface.

Should I sand cedar?

Cedar is soft. Unless the cedar has deep scratches, gouges or planer marks -- lines running perpendicular across the grain -- cedar should be sanded by hand. Power sanders remove material fast, almost too fast for finish work. If you do need to sand it with a power sander, use an orbital sander with 100-grit sandpaper.

How long does it take for Cedar to turn GREY?

It depends on your area and where your fence is in the ground. 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.

How long does it take for Cedar to dry before staining?

A couple of buddies of mine say that I need to wait a year before staining my cedar deck… I would like to wait for a dry period in the weather and then have it stained (within 2 months of building it). My buddies say the stain will not take as well. They say wait until next year.

Should you sand Cedar before staining?

If your cedar deck is newly installed, you'll need to sand* the cedar boards prior to staining. The boards go through a planing process at the mill that result in “mill glazing”. The planing process causes an oily surface on the boards that can hinder the wood stain from penetrating the wood.
