Drywalling a ceiling in your own home can be a difficult task. The joists can be uneven making it difficult to attach the drywall. The narrow rafters can also cause problems when securing the drywall. Is ceiling strapping required when drywalling a ceiling?
Installing strapping on a ceiling is not required when installing drywall but has many advantages at a low cost. Strapping will give you a larger area to secure the drywall when installing. It will also reduce the need for seams and can help prevent cracking in the drywall in the future.
In this article, we will look at strapping, its advantages, and how it is installed to see what the advantages are when strapping a ceiling before installing drywall.
Is Ceiling Strapping Required?
Ceiling strapping is recommended for a few reasons. It will help prevent drywall cracking on the ceiling in the future, especially if there is a floor above it that will create stress on the drywall. It will also help strengthen the joists and reduce the noise transfer between floors.
It will make the installation of the drywall less difficult. It will increase the amount of lumber you can secure the drywall to. Strapping will also help create fewer seams in the drywall and give a nicer, and cleaner appearance when finishing the drywall.
Installing Strapping Yourself
Installing strapping yourself is a simple DIY project and can be accomplished easily by homeowners with just hand tools. It does require accurate measurements but will otherwise be an easy task for DIYers with these skills.
For those new to these projects, installing the strapping will be a good introduction to using different tools which involve measuring, cutting, and attaching the strapping to the ceiling.
What Strapping to Use
Strapping can be found for a low cost at most home improvement stores. It is made from 1X3 spruce or prime lumber and comes in large bundles. Strapping can range in length from 8 ft to 16 ft. The longer strapping may be easier to transport and install depending on your room size and needs.
To calculate the strapping required, you will have to measure across the room and divide by 16, which should be equal to the spacing of the joists. Add one to that number to get the final number of joists. Measure the length of the room and use that number to calculate the length of the straps needed according to the size of strapping available for purchase.
Nails for Strapping
You will need 10d nails to install the ceiling strapping. Do not use finish nails as the strapping will pull through the nails after the drywall is installed. Screws aren’t necessary and they can add to installation time without any added benefit.
You can use a nail at each overlap of a rafter to ensure a good fit. This will lessen the chances of the strapping splitting or hitting the screw head with a nail later when installing the drywall over the strapping.
Ceiling Strapping Installation
Ceiling strapping should be installed every 16 inches and should run parallel across each joist. It will need to run at a 90-degree angle to each joist. It will also need to be exactly 16 inches to the center of each strapping from the first strapping. It will help to measure and place a chalk line to line up the strapping.
A sheet of drywall is 48 inches wide and this will give you four spots to secure the drywall to the strapping. The third strapping will share two pieces of drywall so keeping the strapping inline and at a 90-degree angle is important to maintain ample space for the two sheets of drywall that will need to be fastened to that strapping.
If installing a moisture barrier, ensure to install the moisture barrier first on the ceiling joists. After the moisture barrier is installed, the strapping can be secured to the joists under the vapor barrier.
Conclusion
Strapping is not necessary when drywalling a ceiling but can have numerous added benefits for the low cost of installation. It will help strengthen the ceiling joints especially when there is a second floor. It will also reduce the noise and the possibility of cracks in the finished drywall.
Strapping the ceiling will also allow for easier installation of the drywall giving you a larger area to attach the drywall to on the ceiling. It also reduces the number of seams needed in the drywall, giving it a much nicer finish when done.
FAQ
Can You Attach Drywall Directly to the Ceiling Joists?
It is possible to attach the drywall to the ceiling joists directly. If there is a height concern or other issue when attaching strapping, installing drywall directly to the joists may be the best option. If there is no space or height concern, strapping has many added benefits without added costs and should always be considered before installing drywall.
Why is the Ceiling Drywall Installed First?
When the ceiling is drywalled first, the drywall on the walls overlaps the drywall on the ceiling, creating additional support for the drywall on the ceiling, joists, and strapping above it.
Installing the ceiling drywall first also allows you to make tighter joints. During the installation of the wall drywall, it can be lifted and pressed against the ceiling drywall to create a tighter joint between the two.
Is the Joint Between the Wall and Ceiling Taped?
When finishing the drywall and filling in the joints, you will need to use joint tape or mesh tape on all the seams. This will include the butt seams, edge seams, and the gap from the wall and ceiling drywall. The tape will then need to be mudded, and filled with a joint compound which will harden and hide the gaps between the drywall.
What Are Furring Strips Used for?
During construction, furring strips may have many uses. They can help raise or level an uneven surface. They can also help make room when installing insulation. They can also be used to strap a ceiling for hanging drywall.
