In the process of decoration, from the selection of decoration companies to the purchase of building materials products, many homeowners are unavoidable. However, most consumers still decorate the "outsiders". Even if they stay at the construction site every day, many details cannot be found.
The purpose of the wall surface treatment is to make the wall surface smooth, clean and free of cracks. The general wall treatment has the following several steps: Plasterboard leveling, puttying, wall paint (or wallpaper, tile). People often only notice whether the latex paint or wallpaper of the decorative layer is environmentally friendly, but they do not know that if the base layer is not properly handled, it will inevitably lead to a series of problems such as cracking, falling powder, and blistering.
Before the construction, first check the wall. If it is a rough room, check whether the cement wall is solid and flat, whether there are big cracks or holes; if it is a putty wall, check whether the wall putty is a putty for white powder plus glue. If it is, you must scrape it off. Reprocess the wall.
Some of the walls are seriously uneven, which will use a professional leveling repair mortar to level the wall. This is not only effective, but also saves on putty. After the scraping of putty, it starts to grind the putty one to two days; the putty is polished. After clearing the floating dust on the surface, you can apply the primer; the top coat usually has to be brushed twice, each time between them should be separated by 2 to 4 hours; check to see if the wall surface is flat and the angle of the yin and yang is vertical. No cracks, holes, uniform color, full paint film, etc.
Old room renovation corner needs to be re-leveled
In the old house, there will be corner damage, unevenness, etc. Therefore, when performing wall decoration in an old house, pay attention to the leveling of the corner part.
To prevent putty drying in the summer
The weather in summer is sometimes dry. If you do not use the mixed putty for a day, use some tips to keep it dry. Put a layer of plastic cloth or plastic wrap in a bucket filled with putty, and then pour some water on it. When the next day is spent, simply drain the water and remove the plastic sheet or plastic wrap to continue using it.
Glass fiber cloth can prevent wall cracking
In many housing estates, the wall surface of the house is already a putty finish. However, in order to ensure the adhesion of the wall paint to the grassroots, the original wall putty can be removed and then a layer of glass fiber cloth is attached to achieve a firm connection between the base layer and the floor. Prevent surface cracking and other effects.
Putty at least two times
To level the wall first with plaster, make a leveling layer. The number of times the putty is put is determined by the level of the wall surface, which is usually 2 to 3 times. The first pass must be smooth, even, and smooth. After the putty is dry, sand it with a sandpaper to remove scratches. After polishing, the powder is cleaned and the second pass of putty can be performed. If you want to work finer, you can scrape three or four times.
Materials to be placed in categories
During the renovation, the main materials for decoration, base materials, garbage, etc. should be placed in categories and should not be discarded indiscriminately. On the one hand, construction workers are more convenient when picking and placing materials, and on the other hand they also prevent pollution. In addition, fire extinguishing devices should be equipped on the construction site.
