How to remove old paint from a concrete surface?

Here you can find an overview of the different accessories for drills and angle grinders that are good for removing old paint from concrete. How to choose the right tools for removing paint? What you need to pay attention to?

If you are faced with finishing work in an old room, it is likely that in order to paint the ceiling or tidy up the walls, the first step is. removing old paint.

Otherwise, the old layer will not allow the wallpaper or new paint to set well, and the work will be done in vain.

Carefully remove the cutting wheel

Before you start removing a worn cutting wheel (or any other wheel), you need to buy a new one. Choosing a new disc is not a difficult task. It depends on the nature of the work to be performed.

According to the functional purpose of the nozzles are divided into:

  • Cutting (there are abrasive and diamond, created for cutting products from various materials);
  • Stripping (used to remove paint and rust);
  • Stripping (used for sanding various surfaces);
  • sharpening discs (these are used for sharpening all kinds of tools);
  • sanding and polishing brushes used for finishing.

Diamond cutting discs have different compositions and hardness, so there are nozzles for metal, brick, wood, slate, concrete, ceramics. They are considerably more expensive than others. The most popular cutting wheels for metal. Steel discs are noticeably different from other discs. Although they can be used to cut other metals, it does reduce the life of the bits considerably.

Deburring nozzles are metal discs that have steel brushes pressed into them. Metal parts of brushes chipping off over time, so wear protective gear for this type of work.

Deburring nozzle consists of a base, to which the sandpaper with large grit is glued: from 0 to 00 for coarse deburring and from 20 to 80 for fine deburring. Such a disc should not be used until the abrasive has worn off. Otherwise it tears up.

Sharpening discs are used for rough tool sharpening. They are much thicker than smooth cut-off wheels. When using an angle grinder for this purpose, it must be firmly secured to avoid injury.

Grinding and polishing wheels are used on machines with variable speed. They can also be used on special grinders.

Such an abundance of different tools can be confusing to inexperienced users, but it is a treasure trove for any professional.

The external diameter of the rod, to which the nozzle is attached by means of a flange and nut, is the same for all lathes and is 22.2 mm. The disc size depends on the construction of the tool and is selected from a range of diameters recommended by the manufacturer.

Discs have a factory marking on which, among other parameters (abrasiveness of the working surface, grit, hardness, accuracy and unbalance classes) indicates the size and maximum rotation speed. It should exceed the similar parameter of the angle grinder. Most of the above characteristics are clear without comment, except for the unbalance class. This parameter characterizes the uneven weight distribution of the material of which it is made. It affects the amplitude of the “beating” of the bit.

The tool must be disconnected from the 220V power supply before beginning work on replacing the nozzle. To remove the wheel, you need to include a lock on the body of the unit, which does not allow the flange of the product to rotate. Using a special wrench or an open-jaw wrench, you can try to unscrew the nut. If unscrewing still fails, it is better to put the tool on a flat surface so that the drive was parallel to it and drop a small amount of WD-40 on the threads of the rod of the nut side. After that you need to wait for about 10-15 minutes. The nut should unscrew easily. The special key tends to get lost. Therefore, it is a good idea to attach it to the body of the angle grinder on a flexible strap of sufficient length so that it does not restrict the freedom of movement of the working.

Rules of circle changing on the tool

Due to the fact that the discs for angle grinder have the status of consumables, then sooner or later have to replace. They are fixed on the spindle of “angle grinder” by means of clamping flange (or nut) with M14 thread. The special open-ended spanner supplied with the tool, equipped with a pin on one side, is the right choice for the fastening operation. Below you will find step-by-step instructions for attaching the wheel:

  • It is necessary to de-energize the tool (by disconnecting the battery pack or unplugging the plug from the outlet);
  • Press the button at the front of the housing to lock the spindle of the angle grinder (the spindle is fixed in the stationary position after the stopper enters the hole of the disc placed in the gearbox, after pressing the button);
  • Next, you need to insert the pins of the wrench into the clamping flange (or rather. in its holes);
  • Hold the locking device with one hand and turn it to the left with the other until the nut is released. Then it can already be unscrewed without the help of a wrench and remove it from the shaft.
  • Then you can replace the tooling, pre-cleaning the old one (if there is dust and dirt accumulated inside the housing, you must remove the bottom flange and clean dirt from all bearing surfaces with a steel brush;)
  • The next step is to put the flange back in place. Fix it properly, all the grooves on the flange and spindle must necessarily coincide;
  • Then you need to put the gasket on top of the (lower) flange. It is not necessary to install it, but it is advisable, because it will help you easily unscrew the clamping nut in the future, when you need to replace the tooling;
  • Secure the new wheel by placing it with the marked side (side with information sticker) facing outwards;
  • Install the gasket over the abrasive wheel (if the gaskets were not immediately supplied with the “angle grinder“, you can buy them in a construction store or you can make them yourself from cardboard or tin);
  • Finally, the flange must be screwed onto the shaft by hand. The nut should be screwed all the way in until it can no longer be turned without a wrench. Then, clamping the stopper, you need to tighten the nut with a wrench, but not more than 1/4 turn, otherwise it may deform the circle.
  • When all of the above steps are done properly and in the correct order, the replacement will be considered successful.

IMPORTANT! The clamping flange must always be unscrewed in the direction opposite to the shaft rotation!
