2. How to apply putty?
So the first step: observe the grassroots
Before construction we must first carry out grassroots inspection to observe whether the surface of the grassroots level is firm, whether there are cracks, whether there are empty drums, and whether there is dirty pollution, which does not take much time, but is very important and also need meticulousness.
The second step: clean out the dirt and all the pollutions
After the inspection right, we have to treat these places, clean out the dirt and all the pollutions, as well like local leveling, fill pits, bulldoze, honeycombs, hemp surfaces or scraping wall putty or sanding pre-treatment, right?
And in addition we also need to make sure the wall surface is not too dry or too wet.
The third step: scraping putty
it would be the batch scraping putty forward construction begin.
So when the scraping putty begins, you should pay attention if the water absorption of the grass layer is strong. If it is strong you should the seal is done with a ceiling low glue, low viscosity so that the adhesion of the putty can be enhanced. The tool used for scrap putty is a towel which is used from top to bottom from right to left at a 30 degree angle, like this.
So we need to scrape twice. The interval time is not too short. You should wait for the third for the first time to dry. And then you can scrape a second time.
Each pass of the putty should be thin, not too thick, otherwise it will crack and fall off. You can't scrape too much or from back and forth. No, there will be curls and peelings. Or the glue in the putty will be squeezed out, sealing the surface, and drying time will be slower. So that's basically do and don't. Keep it in mind.
The last step: grind the putty
After the base layer of the putty is dried, it needs to be sanded with a sandpaper.
Of course, the thickness of the sandpaper is determined according to the type of the wall putty. The coarse, for example, the coarse sandpaper is used to grind a hard putty and clean the base layer, right? And the sandpaper is sanded ordinarily. And the fine sandpaper is to be sanded with the glossy putty.
When grinding it, it should be known that it can be used to press your two fingers to the ground. But to wrap the whole sandpaper into a pad, and push and pull, push and pull back and forth many times. In this way the wall putty can be completed.
