One of the most crucial stages in preparing to paint drywall is puttying. In order to achieve a finish that looks professional, this process makes sure that the surface is flawless and smooth. Even the best paint job can become uneven and flawed without proper puttying.
Although puttying drywall may seem simple, there are a few important guidelines to remember in order to do it correctly. Each step, from selecting the proper putty type to applying it correctly, affects the outcome. Knowing these guidelines can mean the difference between a wall that requires no further work at all and one that does.
Knowing the best practices can save you time and frustration when doing drywall puttying, regardless of your level of experience with do-it-yourself projects. To make sure your walls are prepared for painting, let’s examine the fundamental guidelines for puttying drywall.
| Rule | Description |
| Clean the Surface | Ensure the drywall is free of dust, dirt, and debris before applying putty. |
| Use Quality Putty | Choose a high-quality putty designed for drywall to ensure a smooth finish. |
| Apply in Thin Layers | Apply putty in thin, even layers to avoid cracking and ensure a smooth surface. |
| Sand Between Layers | After each layer dries, sand it lightly to create a smooth base for the next layer. |
| Final Sanding | Once the final layer of putty is dry, sand the surface to remove any imperfections before painting. |
| Prime the Surface | Apply a primer to the puttied drywall to ensure even paint coverage and adhesion. |

What to putty GKL with
The vast array of putty mixtures available in hardware stores can make it difficult for a novice finisher to select an appropriate one. Certain compositions are used for work on the ceiling, while others are used on the walls. There are also beginning and decorative putties. We offer both dry mixtures that need to be mixed with water and solutions that are ready to use.
Buying a pre-made solution might be the best choice if the task is minimal, like when we are talking about finishing a single small room. This is particularly true for work done by non-professionals, who are less likely to make mistakes in preparation. This approach’s drawback is that the application-ready solution cannot be kept in storage for an extended period of time.
The binder claims that the putties that make up their composition are:
- cement;
- gypsum;
- polymer.
Cement It doesn’t shrink much and is not very elastic, but it is resistant to moisture. Putties made of it are used in damp areas, such as kitchens and bathrooms. d.
Gypsum dries quickly and is flexible. extremely simple to work with. Such putty’s main drawback is its intolerance for extremes in humidity and temperature.
The compositions of polymer binder are highly adaptable. They lack the majority of the drawbacks of cement and gypsum mixtures and are simple to apply to the surface. The higher cost of the product in comparison to dry compositions is the price paid for quality.
Common putty concoctions:
Knauf High Performance. Brand of putties for starting and finishing that are based on gypsum. It takes 24 hours to dry. Layer thickness ranges from 0.5 mm to 15 mm at its maximum. filled with 30 kg bags. The presence of impurity particles complicates the finishing putty, which is a disadvantage.
SCANMIX TT. composition resistant to water on a cement binder. withstands cold temperatures with ease. Ideal for finishing projects both inside and outside, including those in arid climates. Layer minimum: 4 mm, maximum: 20 mm. Drys in a day, but it takes 48 hours to apply the finishing. Its primary drawback is that it shrinks easily and frequently cracks.
STANDART SCANMIX LH. composition of polymers used in finishing putty. Because of its extremely high adhesion index, it can be used on nearly any surface. It does not shrink in the presence of water. One drawback is the expensive cost.
Osnovit Ekonsilk. Russian manufactured gypsum putty. Drys in roughly five hours. It is easily leveled and has good plasticity. The thickest layer that can be is 5 mm. economical use of the combination. attractive cost. One drawback is that occasionally, cracks show up once the solution dries.
Standard Volma. composition of gypsum plus additional special modifiers. Good flexibility and adherence. minimal heat conductivity. The solution’s lengthy drying time is a drawback.
Vetonit LR+ Weber. Putty made of superplastic on a polymer binder. It serves as a finishing touch. is applicable both manually and mechanically. 5 mm is the maximum layer thickness. After mixing, the solution can be used for 48 hours. Cons: It takes a while to dry, and the 0.3 mm filler size prevents putty from being applied in layers thinner than 1 mm.
Required tool
To execute superior puttying, the ensuing equipment is required:
- Spatula. Necessary for applying and distributing the paste over the surface. Finishers usually have several of them. Wide spatulas are used for processing areas, narrow ones for hard-to-reach places.
- Drill with a mixer attachment. It will be much easier to obtain a solution of uniform consistency from a dry mixture with its help.
- Bucket. For mixing the mixture and preparing the putty solution.
- Plaster float. Needed for leveling and sanding the surface.
- Roller or brush. Required for priming the walls.
It’s critical to follow the correct procedures when priming drywall for painting in order to achieve a smooth, faultless finish. Putty must be applied and sanded correctly to hide seams, screws, and other flaws, leaving the surface flawlessly smooth and primed for painting. To prevent obvious defects in the finished painted surface, meticulous attention to detail is essential at this stage.
How to putty correctly
The master demonstrates in the video how he uses his own hands to putty plasterboard walls before painting them:
Getting the mixture ready. The dry mixture, which weighs about 2.5 kg per 1.2 liters, is poured out of the bucket after water has been added. The manufacturer lists the components that make up the putty on the packaging, and this information determines the ratio. The solution is then agitated with a mixer to achieve a uniform consistency.
Getting the putty started. All gypsum board joints are leveled and the screw heads are hidden with putty. Using a spatula, apply the solution along and across the seams to ensure proper distribution. Tie up the corners can be a little challenging. There are two phases to it. Putty one surface next to the corner joint first, then allow it to dry. The process should then be repeated on the other side. Wait for the solution to dry after completing the step.
Sanding. Sandpaper is used to smooth out any imperfections in the starting putty and enhance its adherence to the finishing layer.
Important: Wearing a respirator or protective mask is required when sanding the wall because a lot of dust that is harmful to health is created.
Putty finishing. In comparison to the first finishing, the solution is diluted slightly thinner. The mixture doesn’t change. The substance is evenly distributed over the whole surface of the gypsum board in a thin layer. Using a wide spatula is the most practical way to do this. The wall is sanded after the solution has dried.
Cleaning the spatula is required once the task is completed. Before the mixture that adhered to the tool dries, this needs to be done. A rag is used to wipe the metal portion dry after any leftover solution has been removed.
Such preparation will leave the plasterboard ceilings and walls smooth and ready for painting.
Before painting, puttying drywall is an essential step in creating a perfect, smooth surface. You can make sure that the outcome is both long-lasting and aesthetically beautiful by using the right techniques.
Make sure the surface is clean and ready before beginning. Apply putty evenly and thinly using the proper kind. Sanding in between coats facilitates the creation of a smooth surface that is prepared for painting.
Recall that persistence and focus on details are essential. An exquisitely painted wall that lasts for years can be achieved by taking the time to putty your drywall correctly.
