While cedar stands up to the elements fairly well on its own, putting a seal or a coat of paint on it can enhance the color and protect the wood from inclement weather. For best results, seal before applying the siding to the wall. This way you can completely seal the cedar front to back, top to bottom, and around all edges. A full seal is important because any space that is missing sealant is more susceptible to water damage and chemical bleeding. 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.

By Robert Robillard on Workshop tips. On decks or porches you can seal all rip cuts as they are installed and seal the end grain after the decking in in place. The end cuts in siding, deck boards and trim all need to be sealed at installation. The biggest reason for sealing wood end grain is because the wood end grain is exposed on an end cut and it absorbs liquids up to times more rapidly than other wood surfaces. Grab a bunch of straws and hold them together — that is how I envision wood end grain. These tiny straws wick up moisture over time from rain, snow and roof splash off.

That's why it is important to use caulking compound. Although most homeowners seem to think that caulking is required only around window frames and door frames - some professional painters seem to think so, too -there are many other places where it should be used. Caulking should be applied where different types of siding meet, where a pipe or cable goes through the house wall and around all dryer vents, attic vents, exhaust fans and air-conditioners that go through the wall. Caulking should also be used where wooden porch posts or railings sit on top of a concrete slab or porch floor to seal out moisture and protect wood against rot. Although most homeowners don't start thinking about caulking until a paint job is needed - and don't think about conserving heat until the first chilly blasts of autumn remind them it is time to start taking steps that will cut down on heat leaks - it is best to apply caulking compound in warm weather.
