What is "Putty Straightforward"?

The so-called "putty white" means that the wall decoration only needs to be scraped with putty powder a few times, and no other decoration is required later. In fact, the putty white is almost the same as the previous "lime white". It's just that the construction process of putty is simpler than that of lime, and the decorative effect is better.

In the wall decoration of our self-built houses, the lowest grade decoration now is putty, which is also a relatively popular wall decoration technology! Putty is straightforward, how can I make it smooth and smooth?

In the wall decoration of our self-built houses, it is very common to use putty as the main decoration. To be honest, the walls of our house are decorated with putty. As for the Well, Brother Yu will give you a thorough explanation first, so that all the ugliness can be covered up with nothing!

The putty process is divided into three parts, which means scraping three times to complete the entire process!

The first pass, the first pass of putty is the wall filling stage. Putty powder is used to fill up the uneven potholes on the wall and the sand holes on the mortar layer (blank wall). The first coat of putty is equivalent to roughly leveling the wall. In fact, it is a preparation for subsequent coats of putty.

Brother Yu shares his experience and operation: Although I dare not say shamelessly that I am a master-level plasterer, in fact, I have many years of experience in plastering self-built houses, and my skills are somewhat prestigious in the local area. of!

Although the first coat of putty is just for "rough leveling" (a local dialect, which does not mean it is a misnomer) on the wall, if the first coat of putty is not done well, it will cause damage to the subsequent coats of putty. The disadvantage is that you need to scrape it several times to achieve the desired effect. However, the cost of putting putty on a self-built house does not allow you to waste more times on the process, and ordinary people do not want to spend more on materials.

So the quality of the first putty is crucial! Our operating habit is that cement must be added when scraping the putty for the first time, because this can better ensure the hardness of the putty powder, and it can also bring a lot of convenience to the construction. For example, the bubble problem that naturally occurs after scraping the putty for the first time is to remove the putty powder. If cement is added to the scraper, the occurrence of "bubbles" can be reduced to a great extent.

For the second time, scraping the putty for the first time is "rough leveling", then scraping the putty for the second time is "precision leveling". In our common saying, scraping the putty for the second time is "precision leveling". It belongs to "covering leveling", that is, the second coat of putty is used to cover the defects left by the first coat of putty.

For example, when scraping the first putty, you need to add cement (black cement). In this case, the whiteness of the putty powder will be weakened, so you need to use the second putty to cover the first putty and restore it. The whitening effect of putty powder itself!

Scraping the first coat of putty at the same time will leave a lot of traces, because the first coat of putty is not convenient for finishing. At this time, you need to use the second coat of putty to "cover the remaining defects." .

That is to say, in addition to precise leveling, the second pass of putty also needs to deal with the defects left by the first pass of putty. At the same time, in order to facilitate the next pass of scraping, it should also be properly cleaned. Light treatment to minimize the "grey knife marks" left behind and minimize the occurrence of bubbles!

Technical operation: The second pass of putty can be finished at the same time. Use scraping a wall as a reference. After scraping from top to bottom, go back and finish the finish from top to bottom. If the climate conditions are suitable, you can shave and polish at the same time (there is no detailed answer for this step, it mainly relies on personal experience and technology to control).

The third pass, the third pass of putty is also the last pass of putty. This step completely requires experience and technical support, because this is the last pass, and it needs to be visually inspected (acceptance standards for putty for self-built houses) The qualified flatness needs to be smooth and smooth to the touch, and there should be no powdering!

The requirements are so high, how can we achieve it?

The main material and the auxiliary material are combined. When scraping the putty for the third time, some auxiliary materials must be added to assist, so as to achieve a smooth and delicate feel! We usually use 108 glue because it is cheap and easy to use! If possible, you can use putty powder special auxiliary glue!

Technical experience sharing: The last pass of putty is about technique. Personal experience believes that the last pass of putty should be done in a "vertical scraping" way for better results. The order of formation is the first vertical scraping, the second Scrape horizontally once, and scrape vertically a third time.

After the last putty is added to the glue, even if it is "scraped and wiped", it will have a certain smooth effect after it dries. After scraping, the polishing time must be mastered and repeated "polishing" ", the force is from heavy to light, from fast to slow, and the operation is repeated back and forth from top to bottom until an effect similar to a "mirror surface" is achieved!

Note: The time for the last putty finishing treatment must be mastered, and the timing needs to be determined according to the climate and personal scraping speed. For example, putty scraped in the summer will dry faster. If the scraping speed cannot keep up with the drying speed, you must seize the time to do the polishing treatment, because it is not suitable for polishing treatment after the putty powder dries (it is easy to get rid of it). pink).

In fact, if you want the putty to be smooth and flat, the simplest requirement is that the base layer of the wall must also reach a certain level of smoothness. If the wall is not smooth, you will need to rely entirely on putty powder to repair it in the future. , this will increase the difficulty of construction, and the labor price needs to be increased! It is recommended that the acceptance criteria for self-built houses be “pleasing to the eye, smooth to the touch, and pleasant to the heart”!
