Installing sheathing is a fairly straightforward process. First, you should measure the area you are covering to determine how much sheathing you will need. Next, make sure that the surface is clean and dry before applying your sheathing material. For wood sheathing, use galvanized nails or screws with washers to attach the material to the substrate. It is important to make sure that the nails are spaced correctly so that they do not create any weak spots in the sheathing installation. For foam sheathing, use either adhesive spray foam or construction adhesive to attach the material. Make sure you follow all of the manufacturer’s instructions for application and drying times. Once your sheathing is in place, make sure that you caulk or seal any gaps or seams. This will help to create an airtight and weatherproof barrier. Finally, apply a layer of a protective coating such as paint or stain to protect your sheathing from the elements. By following these steps, you can ensure that your exterior sheathing will last for years to come.
