However, the cost of emery is less and in self-grinding, it is also suitable perfect. If it is planned to grind on putty on a large area, then you must often change the material.

Grind the walls after putty

Thanks to the table, everything is extremely clear - if the number is greater, the skin will be smaller, and if the number is less, then the skins are coarser.

We carry out work on grinding wall

Now you need to remember the main rule during the grinding of the wall of the post -packing wall: first you need to use coarse-grained skins, and at the last stage - fine-grained.

Grinding after putty

So this work is in such a sequence:

• To begin, it is necessary to wait until the previous layer sucks completely dry and then prepare good lighting and put on a protective mask with glasses
• It is necessary to choose the emery with the right graininess, so the acquired material in the store will not be superfluous to purchase several types of skins. But it comes to understand or not, you can, if you walk with it on a small area of ​​the wall being processed - if the scratches on the putty remain, then we take a big number. Do not worry, after these scratches will disappear
• I have already said that if you want to go around the room with wallpaper, then these defects are not necessary to correct, but it is necessary to get rid of painting from them
• After the emery is selected, fix it on the grinding bar and proceed to the grinding of the surface after putty

• Movements must be circular and uniform. You can still make up-down or left-right - choose a more convenient way for you. The bar must be pressed a little, and in no case do not delay the wall on some kind of wall, otherwise, after that, the putty will appear a new defect
• If you notice the removal on the wall surface, then skip this site, and later apply the required amount of putty and after repeat the grinding again
• All hard-to-reach places of walls and corners should be treated at the very end - a grinding sponge with beveled corners will come to the rescue. Skotroter is not suitable for grinding the corners, as it is rude enough and may need to be needed
• Next, we carry out wet cleaning and view the entire surface, then we apply another layer of putty - the finish putty, and wait until the wall dries
• Now the work on grinding occurs with the help of fine-grained skins. Do not forget that for this you choose the large number of abrasive! The grinding technology has not changed, and all work on the wall is carried out by the same principle as when starting grinding. But there are small nuances: the light is better to put closer, and the movements do not do not smear and more accurate

2. Flat Vibration - Universal Machine
3. Orbital eccentric - thanks to it you can carry out work in the corners
