spackling process, as it were, qualitatively or executed, does not allow to obtain a perfectly flat surface.On the wall there are traces of the spatula, the transitions between the layers, see small bumps, bumps and hollows.

without grinding the surface you can not do.Grinding is a finishing process that prepares the surface for the final finish.

Run sanding after putty can anyone with the desire, patience and perseverance.The main thing is to choose the right tools, consumables and accessories, to know performance technology.

Grinding is done dry or wet.Wet sand is suitable to drywall, plaster under the rule of the walls.The main advantage of the wet grinding in the relative purity of the process.You will not disturb the dust, always present when dry grinding.subsequent cleaning process is forgiven.

in home repair is more often used dry grinding.

Rule 1
Grinding after spackling done not earlier than 24 hours after the application of putty layer.

Tips on choosing tools, abrasives and accessories

Without properly selected tools and equipment to produce high quality grinding walls after the putty will not work.

You must have:

- sandpaper and sanding mesh;

- sanding sponge with cut edges at an angle that allows you to perform grinding in inaccessible places.
sanding mesh
Immediately note sanding grid is not clogged with dust in the process, but is more expensive sandpaper.

must purchase a grinding bar or mandrel to fix the sandpaper or sanding mesh.This device is properly called manual shkuroterom.

Rule 2
Abrasive paper has a different grain.Rooms 20 ... 220 indicate the coarse structure of the material, in room 250 ... 2500 correspond to the fine-grained sandpaper.

of the devices you will definitely need a stepladder, a lamp or a spotlight, a wide spatula.Suitable and wide table or goats if their height allows you to perform work on the ceiling.

To ensure safety when performing grinding work is required to buy goggles, a mask or respirator, cap, beret or shawl.

Let us turn to the process of grinding the surface after spackling.
Grinding the walls and ceiling after plastering is carried out in a well-lit, ventilated area to dry completely.

technology grinding walls

At the first stage with a spatula walk across the surface of the wall.Remove the bumps, all kinds of projections, nodules.When a large depressions or pits zashpaklyuyte them, do not try to deduce by means of grinding.

Rule 3
To start grinding only completely dry surfaces.

lighting installation

Rule 4
should establish quality lighting on one side at an angle to the surface.Its position can not be changed during the grinding cycle.

The second stage involves treating the surface of the coarse sandpaper or a sanding net.Consumables mounted on a grinding bar.

surface grinding is carried out from top to bottom, treating small areas of rotational motion.Plot size must not exceed 1 × 1 m.

Sand better top-down strips no wider than 1 m. Arm movements are produced when grinding in a circle, but you can move up and down or vlevo˗vpravo.

plays the entire surface with coarse abrasive polishing continue using shallow nazhdachki.When using a fine emery material is required to hold the light source as close as possible to the wall.

Rule 5

Never treat corners and hard to reach places using shkurotera.You just spoil the surface.

Rule 6
Choose the right granularity consumables.The correct sandpaper should not leave deep scratches in the plaster.

If abrasive leaves scratch, choose a fine sandpaper.Under wallpaper permitted on the ground surface after putty minor scratches.But under the surface of the painting of the walls must be perfectly smooth.

grinding process is time consuming and requires considerable effort to implement.It can be mechanized, to use a special grinder.Available grinders that provide connection of a vacuum cleaner, which makes the grinding process is virtually dust-free.

Do not use a belt sander.They are suitable to work with wood.Suitable eccentric or orbital sander.
Although the use of grinder accelerates the grinding process, without having special skills to obtain high-quality polished surface novice builder is very difficult.

It should feel right tool not only to move, but also to regulate the force pressing the tool on the grinding plane.And there is such a tool is quite expensive.

After grinding, remove the layer of dust, make wet cleaning and check the quality of the surface.Before finishing always apply a coat of primer.

Tip 1
novice builder is better to use hand-held grinding

Grinding ceiling does not differ from the grinding wall.Process is more time-consuming and requires patience and accuracy.

again on abrasive material

Sanding mesh is more convenient than sandpaper, because they do not clog with dust and debris during operation.But correctly chosen abrasive paper also gives good results, in addition, it is much cheaper.When the sanding after putty walls with his own hands is better to use sandpaper numbers 120 ... 180 (coarse) and finish grinding to perform abrasive numbers 220 ... 280 (fine-grained).

Tip 2
Imposing the first layer of putty, when grinding use grit №120 ... 180.After the second layer of putty should be used with abrasives №220 ... 280.

Sandpaper mesh and labeled the same, on the reverse side of the material.

How to control the quality of the grinding?

At the beginning of the article stated that the grinding process should be carried out in good light, constantly sent from one location.Properly tuned lighting allows to constantly monitor the process of grinding and the quality for glare on the surface or lumen by applying a flat line, building level.Between control tool and the wall should be no gaps.

When it comes to the ceiling, and he is preparing for painting the ceiling need to grind higher quality.grinding zone illumination light, it will see the surface defects.Visible scratches shpaklyuyut and stripped after drying.

grinding operation ends thorough cleaning of surfaces and premises and applying the primer on the dried and polished surface.
Good luck in the dusty reality!
