How to putty drywall

A common material in contemporary construction, drywall provides a level, smooth surface that is ideal for painting or applying wallpaper. However, puttying the drywall correctly is crucial to getting that perfect finish. This method can make all the difference in your home renovation project because it not only covers up the screws and seams but also gives your project a seamless, polished appearance.

It may seem intimidating to putty drywall, particularly if you’re new to do-it-yourself home remodeling. But you can learn this vital skill if you have the right resources and a little perseverance. We’ll walk you through each step in this guide and offer helpful advice to make sure your drywall looks its best.

To achieve a smooth, polished surface, every step is important, from choosing the proper putty type to applying it correctly. Whether you’re repairing an old wall or finishing a new space, being able to apply putty to drywall will help you get the polished look you want.

Now let’s get to work and turn those plain drywall panels into a gorgeously finished wall that improves the overall appearance of your room.

Why putty drywall??

Since it is much easier to putty with rough putty alone, we frequently wonder if it is possible to complete a task without using finishing putty. After all, nobody wants to work extra hard or waste valuable time on pointless work. Indeed, it is feasible in certain situations, but not always.

Every time we work with drywall, we have to smooth out any unevenness that occurred during installation, conceal the screw caps, and seal the joints. Adjustments may also be necessary due to improper transportation or long-term gypsum board storage.

Not just the corners, joints, and screw heads themselves, but also gypsum board sheets can be used without puttying when placed beneath wallpaper or tiles thanks to the Knauf company, one of the industry leaders in drywall production.

They used a unique primer—water-dispersion paint that had been diluted with water—to help them achieve their objective. On the surface of the sheet undergoing processing, this primer transforms into a thin film layer that blends seamlessly with any kind of adhesive and shields the drywall from harm in the unlikely event that the wallpaper breaks.

Therefore, if you go with the Knauf company, the issue of how to putty drywall is moot.

Using a primer for gypsum boards

There are several noteworthy benefits associated with using drywall primer. First of all, it promotes the adhesion of nearby materials, which significantly lowers the likelihood of bubbles and wallpaper or tile peeling off. Secondly, it is uniformly applied across the whole surface, contributing to a lower material consumption.

When finishing a room, primer is a must, particularly when working with drywall, as it helps to increase putty adhesion and decrease the amount of glue needed to adhere wallpaper. In order to improve the sticking power of the finishing layer and prevent issues like rolling or peeling, a primer is also applied after the initial putty.

It is best to select primers based on the kind and degree of the project. Using putties with deep penetration properties is preferable.

Step-by-step instructions for performing the work

You will need to refine the drywall sheets once you have completed installing them. Puttying drywall should be done in two steps or more if painting is your plan.

The following technology is used to putty drywall:

  • Be sure to apply a primer with deep penetration properties to the drywall.
  • Seal the holes left by the screws.
  • We putty the joints.
  • We putty internal and external corners.
  • Apply primer for gypsum boards.
  • Finish the surface with starting putty.
  • Sanding the unevenness.
  • Applying primer to drywall.
  • Puttying with finishing composition.
  • We cover the walls with primer for final work.

We’ll now learn what kind of putty is appropriate for use on drywall. Gypsum and polymer are both utilized. Final finishing uses polymer putties because they help level the surface. On the other hand, depending on the grain size, gypsum can be both starting and finishing.

Dry putty for drywall requires diluting with water, while ready-to-use putty is available in two varieties. Naturally, it is preferable to use the first one since you can be sure that you won’t get lumps if the dosage is off, but it is also ten times more expensive.

Prime the surface

The drywall surface must be prepared beforehand as a dry, clean material, even before puttying. With a vacuum or a moist cloth, we eliminate dust and other impurities. Using painting tools, prepare the primer and lubricate the walls.

It is advised to use a specific primer in high-humidity rooms to stop the growth of mold.

Primarily, drywall is primed in one coat; however, it can be repeated if needed, as in the kitchen or bathroom. The applied layer must dry before beginning the subsequent finishing steps.

Seal seams and screw heads

Special compounds, such as Fugenfuller, Knauf Uniflot, Knauf-Fugen, and their analogues, are used to seal joints. It is advised to dilute these kinds of putties in small doses because they dry out easily.

The ideal way to put putty on screw heads is to use a small spatula to cover the seams as you go.

Gypsum board edges are distinct from one another; they are straight across and thinned along the edge. Naturally, butt joints are a little trickier to seal, but more about that a little later.

Vertical joints

Putty is first applied to the spaces between the longitudinal joints of plasterboard that have a thinned edge.

Next, the wet putty is covered with reinforcing tape, also known as serpyanka. This is required to stop any potential cracks. Pre-soaking for a few minutes is required before using tape. Putty over the tape and then attach it to the joint.

Cut seams

Plasterboard with a straight edge can only be puttied in the areas where the sheets are cut and joined if they are treated beforehand. It is required to wet the plaster at a 45° angle and create tiny grooves after moistening the plasterboard’s edges with water. It’s best to finish this task before priming.

After using a primer to lubricate the resulting joints, fill the seam with putty once it has dried. Using two spatulas, 10 and 20 cm apart, works best. Distribute the mixture, starting with smaller ones. The larger, second one eliminates the excess. It is crucial to properly fill the seam in order to create a tiny bump that rises above the plane. Everything was done correctly if this occurs.

Re-lubricate the seam with recently made putty. The new layer should be roughly half a millimeter thick. Next, we reinforce the seam by adding pre-soaked paper tape to it. With a spatula, scrape off any extra putty.

Making sure that the paper tape is wrinkle-free is essential. Once more, we gather the extra composition and use a thin ball to distribute the putty that is left.

And if so: first tape, then putty?

Some people want to use self-adhesive mesh, paper tape, sickle tape, or glue to cover the gypsum plasterboard in order to save time and money. This junction stays empty in this instance. Such a connection will manifest as cracks and warped wallpaper. Savings are not appropriate in this situation. When wallpapering plasterboard walls, you won’t be disappointed if you use the appropriate technology.

Serpyanka and self-adhesive, incidentally, have serious drawbacks. Serpyanka is stretched and deformed because it is unable to maintain the required rigidity. The fabric’s fibers protrude and cause minor wrinkles when finishing. The self-adhesive mesh separates instantly and doesn’t require any reinforcement.

Puttying external and internal corners

Caulking the corners of drywall is a final but very important step. Paper tape, serpyanka, metal Shitrok, and aluminum corners are used to finish them. Finishing internal corners typically requires the use of serpyanka, or reinforcing tape. The idea is the same as when you finish seams. The excess compound is removed, the joint is puttied, and paper or a sickle is attached on top. The tiniest layer is then applied once more to complete the corner.

External corners are finished with perforated aluminum corners. It is sliced at 45 degrees, or just slightly less. No 90° angle is utilized. In order to prevent the metal from bristling while in use, this is done.

Putty is applied in small amounts at a consistent distance of roughly ten centimeters in order to attach the aluminum corner. It is brought into an even plane with respect to the entire surface by pressing the corner, checking its position, and removing any excess mixture. The edges are sanded again, if needed, once the putty has dried.

Because it has a paper base, the Sheetrock corner is easier to use. Compared to aluminum perforated corners, it is more rigid than paper tape and does not cause abrupt alterations to the surrounding surface.

Installing drywall is an essential step in getting your walls and ceilings finished in a seamless, expert manner. The drywall installation process entails the application of joint compound to the seams and screw holes of the drywall, followed by sanding to produce a smooth, uniform surface that is prepared for painting or wallpapering. Even do-it-yourselfers can accomplish fantastic results by using the right tools and adhering to a few simple steps. From prep to the last sanding, our guide will take you step-by-step through the entire process to make sure your drywall is flawlessly puttied and prepared for the next phase of your project.

Sanding corners and joints

Because sanding is a delicate and dusty task, you should exercise caution. I promise you that you must cover the window with a moist cloth to keep dust from entering adjacent rooms. Using wood shavings or wet rags to cover the floor is also a good idea.

Grinding will take some time if earlier work was done carefully and in accordance with technology.

Initially, all protrusions are removed. The real grinding then starts. The block has a 180–200 mesh sanding mesh attached to it. They carry out the task. Use oblique light for better grinding results. That being said, you can sand wallpaper even less meticulously if it is planned.

Use of personal protective equipment, such as gloves, a respirator, and goggles, is required. Your health will be spared by this.

Prime everything once more after sanding because accumulated dust will obstruct subsequent tasks.
