Finishing the bottom edge of drywall depends on whether it meets a standard baseboard or terminates abruptly. Generally, you leave a 12 12 to 58 58-inch gap above the floor. Hide this gap with standard baseboard moldings, or seal the bottom edge with acoustic caulk/spray foam for an airtight finish.
The back side is more porous and slightly rough, so if you plan to hang and paint the drywall with that one facing front or if you accidentally install the paper backward, do not worry - nothing terrible will happen. You just need more paint and extra coats of joint compound in thin layers to get the desired finish.
Drywall Finishing
Some drywall finishers add a small amount of dish soap (like Dawn) to drywall mud as a workability hack. They do this to act as a surfactant, which reduces the surface tension of the mud.
Two common mistakes made during drywalling are improper joint compound application (such as applying it too thickly or not feathering the edges), and failing to stagger the seams across different studs, which weakens the wall and increases the risk of cracking.
Hanging drywall horizontally (often called "hanging the board") is the industry standard for walls, while hanging vertically is generally discouraged. Horizontal installation provides superior structural integrity and wall strength, creates significantly flatter and less visible seams, and is much easier for the taper to mud and finish.
If you are looking for an alternative to traditional drywall, PVC wall panels (like Trusscore or Duramax) are a leading modern replacement. They install up to four times faster than gypsum boards because they eliminate the need to mud, tape, sand, or paint.
An orbital sander is an option for a large drywall project. This tool is lightweight and can perform the task in less time, but as a power tool it must be used carefully to avoid damaging the drywall surface. Use fine grit sandpaper, between 150 and 180 grit, to achieve the desired results.
For most standard drywall projects, three coats of mud (joint compound) are required to achieve a smooth, professional-looking finish.
The best joint compound alternative depends on your repair size: spackle for nail holes and small dents, quick-setting "hot mud" for large drywall damage, and wood filler for small cracks in trim or woodwork.
Vertical joints in drywall are also called "butt joints." Always leave a 1/2-inch gap at the floor. This allows for floor and wall expansion without cracking the drywall. It also helps prevents moisture wicking if the floor floods.
A Level 5 drywall finish involves an additional skim coat of joint compound over the entire surface, providing the highest-quality finish. This level is essential for areas with critical lighting conditions, where the appearance of the wall is paramount. It can deliver a smooth, uniform surface.
For a small-scale installation, hanging drywall yourself might be more cost-effective. But as your project grows, you will benefit more from hiring a contractor. Of course, working with a licensed contractor means your project most likely will improve in quality, too, thanks to their years of experience and expertise.
One of the most immediate and obvious consequences of forgoing drywall tape is the appearance of visible seams and cracks. You'll have uneven, unsightly lines running across your wall that will make even the most forgiving paint job look terrible. Drywall is not a fan of moisture.
Drywall finishing requires three sequential coats of joint compound (mud): taping, filling, and finishing/sanding. To achieve a seamless finish, work in a specific order: butt joints, flat seams, inside/outside corners, and finally screw heads.
Nails can still be used in certain situations, such as for temporary fixes or small-scale work. However, for all but the most minor drywall jobs—particularly ceilings or permanent installations—drywall screws are the smarter, more modern choice.
Some drywall finishers add a small amount of dish soap (like Dawn) to drywall mud as a workability hack. They do this to act as a surfactant, which reduces the surface tension of the mud.
Applying too little mud can result in a weak, fracture-prone joint. Additionally, it could make it challenging to get a smooth finish. Apply enough mud to thoroughly cover the joint to prevent this error. Spread the mud evenly over the joint using a taping knife, ensuring you fill any gaps or holes.
Yes, a fan will help standard drywall mud dry faster by circulating air and speeding up moisture evaporation. However, it is important to understand the type of mud you are using, as fans work best on standard premixed compounds but won't speed up the curing time of chemical-setting compounds.
The Golden Rule of Sanding means not skipping more than one grit through each step of sanding a surface. This is a basic rule anyone should follow whether they are working with metal, wood, or any other surface. Every scratch you make must be removed by the next finer grit.
Essentially, the 'trick' involves using a pencil to mark a wooden surface before you sand it. Next, you sand it until no more marks remain. And the idea of the technique is to make sanding even and ensure that you don't sand too much.
Before the widespread adoption of drywall in the 1940s and 1950s, older houses used a method called lath and plaster. This technique consisted of nailing thin wooden strips (lath) horizontally across wall studs and coating them in thick layers of plaster.
Neither tape is universally "better"; they both excel in different situations. Paper tape is generally stronger and more crack-resistant, making it ideal for high-stress areas and corners. Mesh tape is easier to use, self-adhesive, and moisture-resistant, making it perfect for quick DIY patches and bathrooms.
Smooth ceilings and knockdown texture are the top choices. Smooth finishes are preferred for modern, high-end, or minimalist spaces, while knockdown (a mottled, dimensional look) is widely used to conceal minor imperfections. Skip trowel is also trending for a rustic, artisan plaster look.
