Step 1: Clear the wall. There is a small white powder on the wall, indicating that the salt in the wall is “precipitated†during the drying process of the cement. At this time, you can brush it off with a nylon brush or iron brush. After a few days of observation, it is determined that there is no longer a white powder. Precipitate, and wait for the cement wall to dry and flat, you can paint.
If the white powder on the surface of the cement wall is plentiful and continuously precipitated, after cleaning it, you can apply a primer on the surface of the wall to prevent salt erosion and the formation of wall cancer in the future; II Do not use oil paint or water-impermeable wallpaper within three months. Brushing or renovation.
Step 2 In addition: Remove the peeling paint film.
Remove the peeling film with a knife or iron brush, and then use a sandpaper to polish the surface. Step 3 Demolition: Remove paste pasted wallpaper.
Step 4 Repair: Trim the surface. Fill the cracks in the pit with a batch cutter, wait until it is completely dry, and grind it with sandpaper.
Step 5: Treat wall lesions.
Step 6 Primer: Apply primer first. The "primer" coating is used exclusively for wall surfaces that do not require special treatment. For problematic walls, the "primer" that specializes in this particular problem must be selected for the problem.
Step seven finishes: paint again. It is generally used paint.
Step eight brush: brush from top to bottom. After the paint was evenly mixed with a wooden stick, the brushing process started from the ceiling and brushed again, so as not to cause the paint that had fallen from the smallpox to finish the finished wall.
Tips: Calculate the amount of paint Formula One: The total brushing area converted from the floor area Algorithm: Total paint area = four walls of paint + ceiling paint four walls of paint area = ground area multiplied by 2.8 ceiling paint area = floor area multiplied by 1 formula two : Estimated amount of paint on the repainted wall = Total painted area divided by the unit area Painted area Stucco walls Tips To increase the adhesion of the lime slurry, a small amount of salt may be added during the preparation of the mortar (usually 100 parts of quicklime plus 7 parts) salt). This brushed wall is not prone to dust.
If a 0.5% blue starch or blue ink is added to the slurry, the brushed walls can be made whiter. Several key issues for stucco walls:
1. To paint and decorate the newly painted paper gray wall, wait until the outer layer of lime is completely dry before proceeding. Otherwise, the effect of beautification will be caused by the appearance of flower spots on the wall.
2. During the process of brushing the lime slurry, the lime slurry should be continuously stirred, otherwise, the lime slurry will precipitate, and there will be different shades of light on the wall after brushing.
3, when painting, should master the principle of top-down, a set of brushstrokes, vertical brush, but also from the left to the right horizontal brush, but should pay attention, do not miss the pen.
4, in the dark old lime wall (excluding plastic white wall), including the spot more refreshing color on the wall, you should first use white gray water full brush again, until the dry white color refresh.
5. If the painted lime wall is no more than half a year old, add an acidic colored drywall powder. If the color is green, sky blue, etc.

Plasma Drilling & Cutting Machine is two function on one machine .
1. Plasma Cutting Machine :different sheet need different power source, China HUAYUAN or USA Hypertherm power source can choose.
2. Drilling :drilling function is one auxiliary function of plasma cutting machine .if the hole diameter is too small , drilling function is better choose instead of plasma cutting .2mm-18mm is standard drilling diameter
3. This two functions can choose one or two
