Staining Cedar

Although some individuals advise that cedar be painted with acrylic, most woodworkers prefer to stain it since the inherent beauty of the wood is best retained this way.

To stain cedar efficiently, the first thing to do is to wash and then sand the wood to moderately roughen the surface so that the wooden stain and sealant cling securely to the wood's surface.

Apply a stain specifically for cedar wood, comprising oils and resins that penetrate deep into the wood’s grains. Apply numerous thin coats of stain through the wood grains using protective suits and a sponge or paintbrush. Apply the stain with a sponge in circular motions, gradually increasing the tone to intensify the stain.

When sealing cedar is used, it provides extra protection to the cedar wood by resisting humidity while also preventing solar rays from changing the color of the wood.
