At the golden age of “Jin 9 Silver 10†home decoration, wall decoration was the focus of home improvement. However, due to improper construction or material purchase problems, it will cause a series of wall problems, such as chalking, peeling and fading. It is the most common and difficult to use wall decoration, and the wall caused by different reasons. The solution to the problem is not limited, and the same method cannot be used blindly. Otherwise, it is likely to be less effective. In this issue, Xiao Bian will introduce to everyone how to deal with the wall problems and let us know more about it.
| First aid four methods restore home beautiful wall surface |
Eradication of scraped parts
If a white wall or a bare wall is partially drummed or slightly cracked and peeled off, the problematic area can be removed and the edge of the removed part can be smoothed, scraped once, put on the primer, and then painted again, but it may be There is a slight color difference with the original wall.
Professional reinforcement for the grassroots
In the case of severe local flaking, it is necessary to consider whether the basement wall is not ready at all. The original wall is removed to the base of the wall and re-applied with an interface agent or a sealing primer, and then leveled and plastered with a plastering plaster (stiffened and cracked) and polished after three batches of scratching the wall. Grassroots quality will be much better at this time.
Direct rolling brush top coating partially
If it is a simple discoloration, it is generally recommended to use a roller brush to cover a new round of primer and a similar topcoat. However, before construction, the quality of the putty layer on the wall must be judged at first: The worst piece of water is soaked with a spatula and the hard spatula is used. If there is no powdering or shedding, it means that the quality of the original putty layer is good. It can be polished with a fine sandpaper and then cleaned with a new primer and finish. You can.
Demolition of the old wall full construction refresh
Total construction is equal to redecoration. The amount of work is the largest, and it is applicable to walls with cracking, peeling and powdering. First, the walls should all be removed to the cement layer. If the houses are not renovated for a long time (such as before the 1980s), they need to be removed to the surface of the brick wall, and then the wall surface is fully constructed: the flat wall surface - the solidified base layer - Brush interface agent - scrape three times with water-resistant putty - wall grinding - once again on the primer - on the top two effects paint.

Abrasive Flap Disc
Abrasive flap discs, commonly known as flat emery cloth wheels, flap discs, flower impellers or elastic discs, are a large variety of coated abrasive conversion products. It is a method of pressing the cut coated abrasive discs one by one. It is formed by sticking adhesive to the back cover plate along the circumference.
The Flap Disc is mainly installed on hand-held Power Tools for grinding and polishing the welds, burrs, chamfers, surface derusting, surface polishing, etc. of various metal and non-metal parts. Compared with the resin grinding wheel for fixed abrasives, it has Grinding and polishing can be completed at one time, shortening the operation time, saving the cost of grinding, and improving the grinding efficiency. The abrasive self-sharpness is strong and the utilization rate is high. The air cooling does not damage the surface. The surface quality is easy to control and cost-effective, reducing operator fatigue and increasing machine life. And so on, so it is widely used in various industries or fields of manufacturing.
The related abrasive products we can supply is Flap Disc Adhesive, Flap Wheels , bonded abrasives, and Abrasive Sanding Disc, such as Abrasive Fiber Disc, Sanding Screen Disc, abrasive silicon sandpaper, if you have any needs about abrasive tools, please kindly feel free to contact us.
Abrasive flap disc can be divided into flap disc, Mini Flap Disc and Flexible Flap Disc according to their shape. There are subtle differences in usage. The flap disc are relatively hard and not easy to bend; the blades of flexible flap disc can be bent at will. Shape, suitable for grinding the edges and corners of the workpiece; mini flap disc is suitable for grinding smaller workpieces. The following is a detailed introduction of the flap disc.
According to the different abrasives, it can be divided into Zirconia Flap Disc,S/C Flap Disc, Ceramic Flap Disc.
1.Zirconia Flap Disc
Mainly used for high alloy, stainless steel and heat-treated steel; high-tensile, non ferrous metals.
2.S/C Flap Disc
Mainly used for marble, stone, glass, and non-ferrous metals.
3.Ceramic Flap Disc
Mainly used for grinding stainless steel, titanium, inconel, and other hard metals.
At present, flap discs are widely used in automobiles, stainless steel products, metal products, glass manufacturing and other industries, and have special effects on welds, solder joints, flash, rust removal and surface polishing. The reason why the flap disc is so widely used is because it has five advantages that cannot be ignored:
1. The flap disc blades have high hardness, high strength and strong grinding ability during use.
2. The flap disc has low noise, low vibration and long service life during use.
3. The flap disc has strong wear resistance and long service life.
4. It is not easy to generate heat and burn parts during use.
5. The use of flap disc can improve work efficiency.
The flap disc blades can be used instead of resin Grinding Wheels and steel wire wheels. They have a good effect on rust removal, grinding and polishing. It is a good way to polish and remove rust. It is worth choosing!
