Sealing Cedar Siding
If you intend to apply a sealant to your home siding, you must clean the surface of the wood. Avoid pressure washing the wood, for it can damage the wood. So, it will be best to wash it by hand. Then, allow it to dry completely before you apply the sealant.

Failure to seal the cedar can leave it at the mercy of the harsh aspects of nature. Yet, if you seal it wrongly, the cedar may bleed or undergo chemical bleeding. Cedar, for example, bleeds chemical extracts once it gets wet. These released chemicals can darken the surface of the wood when the wood dries.
These chemicals also leave streaks that you can see through the paint or stain layer. You can prevent this bleeding by sealing the wood tightly. It will be best to apply many coats of sealant on the wood surface if you inhabit a wet climate.

If the cedar is new, you should clean it. You can utilize a damp cloth to wipe the surface of the wood. If the wood is dirty, you can use a dishwashing liquid and a brush. You can start brushing the dirt off the wood surface. Moreover, you should not use a pressure washer, for it can damage the cedar.
Once the wood surface is thoroughly clean, let it dry before applying the sealant. You can either apply the sealer using a roller or a brush. As you apply the sealer, ensure that you coat the surface of the wood evenly.
Focus also on the edges and joints. These parts are more exposed to moisture. So, you need to apply multiple coating on these parts. Repeat the application of the sealer several times until you are confident that you’ve sealed the entire wood. It will also be best to apply sealer once a year.
