UNIT 12: INTERIOR DOORS AND TRIM UNDERLAYMENT Tools Used  Skill saw  Hammers  Tape measure

  

Pencil T-square Chalkline

Materials Used  1 7/8" ring-shank nails  ½" pressboard How To Install Underlayment 1. Cut underlayment (½" pressboard), to fit in areas where vinyl floor or wood laminate will be installed. 2. Project under the door to where the transition will not be seen when the door is closed. 3. Attach underlayment to plywood sub-floor with the nails every six inches around the edges and every 6 inches in a checkerboard pattern in the middle of the underlayment. 4. Do not be too concerned with an absolutely tight fit. We will use Fix All to fill in any voids.

How to install interior trim 1. The first thing to do is to trim the doors. Begin by measuring from a piece of ½" underlayment on the floor, to the middle of the top piece of the doorframe. This is the side jamb of 2½" MDF. You will need one for each side. After the sides are hung on the inside and outside of the door, measure, cut and install the top bead and head jamb. The 3½" head jamb should be the same length as the side to side measurement. The top bead will project ½" on each side.

While one group is working on the doors, another can go around and work on the windows. Measure the windowsill and cut a piece of 1x8 MDF for each. You can use the same measurement for the piece of trim that will go underneath the windowsill. Pre-drill the 1x8 and attach with 2 inch nails and then attach the trim up tight to the bottom of the window sill. Once a door is trimmed out, a group can begin the base molding in a room. You will be measuring from corner to corner and making coped cuts on inside corners and mitred cuts on outside corners. Please be very accurate with your measurements. Once the pieces are cut, they need to be installed ½" off the floor to allow the carpet to be tucked underneath. The easiest way to do this is to use a scrap piece of underlayment and rest the base molding on it. When nailing the base molding on, make sure the nail is low enough (not more than 1½" off the floor). Please work from the farthest point away from the door toward the door.

UNIT 12: INTERIOR DOORS AND TRIM INSTALLATION OF INTERIOR DOORS Tools Used  Level  Tape measure Materials Used  Shims  2" finish nails  3" screws

   

Power drill, drill bits, and screw bits Pencil

Pre-hung doors Bi-fold doors

Installation of pre-hung door 1. Remove packing 2. Open the door and remove one screw from each set of hinges on the doorframe only. You will be replacing these with the 3" screws when you mount the door in the opening. 3. After removing the three screws, close the door and set the door in the opening so the door swings into the room. Place the door on top of ½" scraps and center it in the opening at the top. To hold it, shim at the very top on both sides. 4. Check the “reveal” by having one person stand on each side of the door after it is in place. The reveal is the distance between the doorframe and the wall framing. As a starting point, we want the reveal to be equal around the door frame. 5. Use a level to check the hinge side of the door and place shims at the location of the screws in the hinges. When the hinge side of the door is correct (level both ways), use three of the 2 inch nails and nail into the hinge side of the door, one nail per hinge. 6. Open the door and pre-drill the holes where you removed the screws earlier with a 3/32" bit. Now you can put in the 3" screws. Apply plenty of pressure and go slow with the drill so as not to strip out the 3" screws. 7. Now the one side is set. Close the door and check the gap between the door and the doorframe. This is the reveal around the door. We want to make it equal along the top and then equal down the side. Use shims as needed and attach with the 2" finish nails. 8. After the door is set, use a punch to set all of the nails. We will go back through before we paint and caulk the nail holes. Installation of bi-fold door 1. Remove packing and follow directions supplied by manufacturer 2. Measure and set the brackets that support the top and bottom pivots of the bi-fold door 3. Insert the doors 4. Check operation of doors 5. Adjust pivots or overhead tracks as needed for smooth operation of doors 6. Install door pulls Maintenance and adjustment of interior doors 1. Keep up finish 2. Keep door knobs and pulls tightened and in working order 3. Make necessary adjustments to bi-fold doors 4. Hanging and swinging on doors can pull them off the tracks or out of line, so that they no longer work properly

UNIT 12: INTERIOR DOORS AND TRIM Maintenance and Safety for Cabinets and Countertops 1. Keep up finish 2. Moisture issues, especially under the sink cabinets—plumbing maintenance 3. Laminate countertops are not indestructible; do not put hot pans directly on surface. 4. Do not hang or swing on cabinet doors 5. Maintain any optional door and drawer knobs you may install 6. If small children are in the home, check into childproof devices for cabinets

HOW TO HANG PICTURES, SHELVES, CURTAIN RODS, AND OTHER ACCESSORIES 1. Locate and mark the studs in wall at desired height or placement or your item. 2. Measure accurately and make sure your measurements are level. 3. Follow package directions for towel bars, curtain rods, shelf units or other accessories. To locate studs: 1. Rap on the wall with your knuckle. You don't have to knock hard for this to work. 2. Move sideways along the wall, still rapping, and listen for a solid sound. Remember that studs are usually placed 16 inches apart—but you can't always count on this. 3. If you don't trust your ear, use an electronic stud finder, available at most hardware stores. It beeps or flashes when it passes over wall studs or ceiling joists. 4. Try to locate the center of the stud. (This will be halfway between the edges detected by an electronic stud finder.) 5. Stud finders are not always reliable. Drill a hole or pound in a nail to be sure you've found the stud. 6. If it is not possible to locate a stud or backing, use drywall anchors. SAFETY ISSUES 1. Blinds with cords may be unsafe if infants and small children may be near them. 2. Accessories usually are not designed to hold the weight of a person, hanging on them could result in injury.
