If you do not own a pressure washer, you can easily rent one and use it to clean the entire wooden fence. It is important to first wash the entire fence so that you can identify any damage to the wood. Remember to take your time while washing and thoroughly examine the entire fence afterward.
Sand down the damaged areas of the wood using a belt sander. Be sure to sand the entire fence board surface that you want to restore.
Restore damaged areas:
After sanding the fence you will need to use the wood putty to fill any damaged areas. Once the putty dries you can use some sandpaper to get a nice smooth finish. You can now apply a nice coat of varnish or paint using the brush. Remember to replace nails and screws that might be damaged.
It is very important to first check the fence posts as they provide the entire structure with the necessary support. Carefully check each post and make sure that they are fixed firmly to the ground and do not move back and forth. If any of the posts move, then it is a good idea to replace it. You will have to remove the old post using the hammer and install a new one. Take the auger and make a hole in the ground deep enough to support the post. After placing the new post, add some cement around it so that it stays in place.
Once you have finished inspecting all of the posts, it is a good idea to check the fence boards. You will need to look for any rot or splintering that might have occurred to the wood. Also, check for any potential mildew or mold that might be growing on the fence boards. If you find any boards that are in really bad shape, remove and replace them using hammer and nails.
