Exterior Wall Covering

Exterior Wall With Bevel Siding


Basic Construction And Carpentry Techniques Home

Many different kinds of siding can be put on exterior walls. They are as follows: wood siding, drop siding, board siding, channel rustic siding, bungalow siding, dolly varden siding, log cabin siding, tongue & groove siding, and bevel siding. The number of siding courses is determined by measuring the distance from the underside of the soffit to 25 mm or more below the bottom plate on the foundation wall, and dividing this distance by the maximum weather exposure of the siding. The maximum weather exposure is calculated by subtracting the minimum siding overlap or headlap from the overall width of the siding. The minimum headlap is 25 mm, for 89 mm and 140 mm siding widths, and 32 mm for widths over 140 mm. From the foundation wall location, layout the siding vertically on the exterior wall over the sheathing building paper. Adjust the siding exposure downward (and overlap upward) on the layout so that the bottom of the siding board that passes over the top of the first floor window coincides with the window cap. Do not increase the exposure to help layout the siding because 203 mm is the maximum exposure allowed. All of the siding will have with the same exposure and overlap. The siding may have to be treated with water repellent also. Mark the siding foundation wall location every 600 mm horizontally along the wall. Snap a chalk line at the marks and nail a furring strip 10 mm above the line to provide support for the starting course. Place the butt end of the siding along the chalk
line. Nail the siding to the bottom plate below each wall stud. Measure the amount of overlap along the top of the siding and snap a chalk line to mark the location of the butt edge of the second course of siding. Apply the rest of the siding so that the vertical butt joints between the boards are staggered, fit tightly together, and fall on a wall stud. Siding should be fastened to each wall stud with only one nail. Never nail through two or more pieces of siding on to a wall stud. The nail should be flush (level) with the siding surface so the siding is snug but not tight against the wall studs. The siding ends can be made to fit tightly together by making each board length 2 mm too long and by bending and snapping the board into place in the wall. Cut each siding board that passes under a window sill, to fit the sill groove shape. Set siding on drip caps that are installed over doors and windows. Trim the last course of siding to fit under the eaves and apply a molding if necessary. Outside corners can be modified in 3 ways. Cut the siding to length and miter the corner edges before application, cover the corners with corner boards before applying the lengths of siding that will butt into them, and cut and apply the siding lengths so they will be even with the outside corners of the building before covering the corners with metal corners.
