Tin sheets come in several different designs and are used for a variety of projects. You can use corrugated tin sheets to cover your walls. Corrugated tin offers protection from the elements and from accidental impacts from small objects. The corrugations are a series of valleys and ridges that run the length of the tin. Installing these so that the corrugations are vertical will help channel water down the wall, into your french drain system and away from your house.
Stand a piece of corrugated tin against the exposed studs or plywood of the wall. Hold the sheet of tin so that the corrugations are running vertically to effectively channel the rain away from your wall.
Slide a rubber grommet onto each nail. Push the grommet all of the way to the underside of the head of the nail. Drive a row of 2 inch galvanized nails through each valley of the tin that is resting on a stud. Leave 15 inches of space between each nail in every row.
Unroll foam rubber weather stripping along the last ridge running the length of your sheet of tin. Press the weather stripping firmly against the tin so that the self adhesive glue on the back of the strip sticks securely to the metal. This gasket will insure a watertight seal when the next piece is set in place to properly overlap this one. Cut the foam rubber with a razor knife as needed.
Hold a second piece up to the wall. Maneuver the new piece so that the first ridge and valley of its corrugation overlaps the last ridge and valley of the previous piece. Attach the two ends to each other and to the wall with a row of nails to match the rest of the installation.
Continue fastening tin sheets to the wall. Use prefabricated corner pieces to lock the walls together. Cut the corner pieces and standard sheets of tin with tin snips where necessary.
Caulk the seams between the sheets and the gaps between your cutouts and the fixtures that protrude through them. Caulk the bottom and the top seams and wipe each bead of caulk smooth with a wet rag.
