Installing Drywall: Mudding and Taping


Installing Drywall, or hanging drywall as the professionals usually refer to the task, can be done by the homeowner. However, it is usually best done with two or more people as it requires significant lifting of heavy material. Mudding and Taping can also be performed by the homeowner, however these tasks require some practice and artistry.


Again, start with the ceiling. Using the wider taping knife apply a generous amount of joint compound over the taped seams as you want to build up the area over the tape. Taking large strokes smooth the joint compound over the tape applying more pressure to the side of the taping knife further away from the tape. This will help to leave more mud over the tape. When complete, the mud should cover an area that extends beyond the width of the tape by 2 to 3 inches.Rows of drywall should be applied in a staggered pattern. This will create an interlocked pattern that creates a tighter and stronger ceiling/wall.SandingSafety� Garage should be close to the kitchen, preferably next to it, so that you have an easy access to the refrigerator or pantry while carrying your groceries to the house. It makes your job much easier for garbage removal as well.Taping and MuddingOnce the first coat has been applied let it sit overnight or until it is dry, prior to starting the second application of Joint compound. Make sure to completely clean off the taping knife, the mud easel and any other containers or instruments that have mud on them prior to finishing up for the day.In addition to the Lift or Jacks, a drywall screw gun, hammer, T-square, carpenters knife, drywall saw and a keyhole saw are required. The keyhole saw is used for cutting around electrical boxes.Prior to starting drywall installation, you need to obtain the proper tools. A Drywall Lift really comes in handy when hanging sheetrock/drywall on the ceilings. You can rent Drywall Lifts at hardware or home improvement stores. If your budget does not allow for this cost, Jacks (or Ts) can be made out of 2�x 4�s. The Jacks (or Ts) should be of a length such that they are just an inch or two taller than the height of the ceiling and have a cross beam that is approximately 3� in width. Usually there are a couple of 45o angle braces connecting the crossbar to the main stem of the Jack. The Jack can then be used to hold up the drywall to the ceiling while it is screwed/nailed into place.� Include at least half a bath on the first floor when planning a two-story house.For bathroom areas where ceramic tile is to be applied, e.g. Shower/Bathtub areas, Concrete board should be used. The concrete board is also referred to as Wonderboard or Durock.� Plan carefully on where to put washer and dryer. It is a good idea to have them on the second floor, next to the master bedroom, in order to avoid going up and down the stairs with your laundry. Take the noise into consideration, though. Calculate extra plumbing costs as well. If it all makes sense, go ahead and do it.For purposes of efficiency and strength it is best to apply the large sheets of drywall over the doors and window openings and cut out the excess later. This will create stronger/cleaner looking walls and save significant time.For the outside corners, using the broad taping knife apply a generous amount of joint compound and flare out the material such that it extends out 6 inches or so from the corner. Again, apply more pressure to the blade side that is further away from the corner so that you leave more mud nearer the outside corner.After the ceiling has been completed it its time to move on to the walls. Drywall should be applied from the top down, with the sheets hung perpendicular to the floor joists or studs. Again the rows should be staggered. The bottom piece should sit about � inches from the sub-floor.After the seams have all been completed, apply a second coat of mud over the screw/nail dimples. With this second coat, flare out the mud over the dimples such that the diameter of the mudded area is about 3-4 inches in diameter.Almondbury, May 11. Victim awoken by knock at the door. When he asks who it was suspect replied police. Victim opened door and two suspects walked into house and stole wallet. Youth later arrested. Lepton, May 11.

Thief smashed car window, reached in and remove radio from display. Greenhead Avenue, Dalton, May 15. Black Honda motorbike secured with heavy chain through the wheel. Bike reg no YH60RVW.� Two-story house usually costs less to build than one-story.Applying the Final Coat of MudPrior to hanging the drywall, make sure the building inspector has first approved the Framing, Plumbing, Electrical and Insulation jobs. Secondly, a vapor barrier should be applied over the insulation on the outside walls if un-faced insulation was installed. Frequently sheets of plastic are used for creating the vapor barrier. The plastic is simply stapled to the framing, covering the insulation.Once the second coat has been applied let it sit overnight or until it is dry, prior to starting the final application of Joint compound. Make sure to completely clean off the taping knife, the mud easel and any other containers or instruments that have mud on them prior to finishing up for the day.Sanding is a very dusty and dirty mess so please uses goggles and a mask. I find it best to use a pole sander with an open screened sand paper material specifically designed for sanding sheetrock/drywall mud.� Plan your traffic patterns ahead of time. Observe where you spend most of your time and plan accordingly. Try to avoid putting any obstacles or doors in the way of major traffic paths.After the first coat has thoroughly dried, it is now time to apply the second coat of mud. It is this coat that should hide the tape.Again start with the ceiling. Apply a skim coat of joint compound over the surface of a seam using a 6� wide taping knife. If the seam is wide, apply a liberal amount of joint compound to fill it. While the Joint compound is still wet, apply the fiberglass tape over the skim coat of Joint Compound. Make sure the seam is centered under the tape. Once the tape has been installed, apply additional Joint Compound over the tape, again using the 6� wide taping knife. Continue this for all of the seams. Note: the tape will still be visible. Additional coats will eventually hide it.� Do you want a basement or can you live without it? Adding a full basement is costly but you should be able to recoup the cost at the time of sale, especially if your house is in the area of homes with basements.Here are things to look for while designing your floor plan:Joint Compound and Fiberglass tape will also be required for Taping and Mudding. Joint Compound typically comes ready-mixed in 5 gallon containers. I would suggest 1-2 containers per 500 square feet of drywall. Fiberglass tape is quite inexpensive so I would suggest picking up 2 to 3 roles for most Do-it-Yourself drywall projects.* ROBBERY - Morrisons supermarket, Penistone Road, Waterloo, May 10. Pickpocket stole purse from shopper's bag.For the inside corners a Corner knife may come in handy. Corners involve a little artistry so again take your time. Apply a generous amount of joint compound and then run the Corner knife down the corner starting from the top. Take long, even strokes. A 6� taping knife may also be helpful to smooth out any imperfections.Preparing the site for DrywallFor the corners use the broad taping knife and add just enough mud such that you can flare out the mudded surface area to about 8-12 inches, taking care to filling in any lines or dimples.Installing Corner beadApplying the Second Coat of Mud� Consider proper room layout for noise. You do not want to have a library or bedroom next to a playroom or close to the area where TV or stereo unit is.* NUISANCE MOTORBIKES -Police are still getting calls about off-road motorcycles being ridden in and around the Skelmanthorpe area. These motorcycles are anti-social and dangerous. Hopefully the off-road motorbike team will be on hand again soon to assist us. We are gathering evidence against these riders, and we appreciate every call that we get about them. If you see these motorbikes, please call 0845 6060606 to report them. Thanks for the calls, please keep them coming.Measuring and Ordering Drywall� When you decide to build a bedroom above garage, be ready to live with the noise caused by the opening and closing of garage doors.Once the drywall has been installed, corner bead should be applied to all outside edges. Corner bead should be nailed every 6-8 inches and penetrate the framing.The inside corners are usually the most tricky and require practice. Patience is the best advice and note that additional coats will be applied later to smooth out any imperfections.After the seams have all been completed, apply a final coat of mud over the screw/nail dimples. With this second coat, flare out the mud over the dimples such that the diameter of the mudded area is about 6-8 inches in diameter.Drywall ToolsDrywall screws or ringed nails will also be required. Typically I use 1.25� length screws or nails. Also, strips of corner bead will be required.After the first coat has thoroughly dried, it is now time to apply the final coat of mud. It is this coat that requires the most artistry and the least amount of joint compound. Here you are simply applying a final skim coat to the already mudded areas.CONTACT: Dave Whitteron, Neighbourhood Watch Liaison, Kirkburton Police Station, Telephone: 01484-436840 or email: dw368@westyorkshire.pnn.police.uk or call Crimestoppers on 0800-555-111

Once sanding is complete, vacuum up the dust and you are ready for priming and painting the walls and texturing the ceilings.
