Drill Nozzle For Paint Removal
Method of removing paint by mechanical action
Mechanical methods of stripping paint include cleaning with hand or power tools. The most common tool for removing paint from large surfaces is an angle grinder or an angle grinder (angle grinder). If an angle grinder is used, a special wire brush (brushes) is fixed on it instead of a disc. You can also use a drill with a metal tip. This method is suitable for cleaning wood and metal from oil paints.

Removing old paint angle grinder with power brush
To clean concrete, stone, plastered walls from water-based paints, surface grinders with coarse-grained sandpaper, with a grain size of 250-600 microns, are used.
The manual method of removing paint with a spatula or scrapers is also referred to as a mechanical method. This process is quite long and laborious, but the most affordable. Removing the paint by hand will not give you a completely cleaned surface, so use it in combination with other methods, or at the stage of finishing preparatory work. The advantage of the manual method is the ability to remove any paintwork.
Such devices in production remove various errors in working with structures made of various metals and concrete products, for example, sagging formed during floor pouring. The grit size of the fixture significantly affects the quality of grinding or polishing work.
Variety of attachments
Also for such purposes it is convenient to use old Soviet metal spatulas. there is a fairly thick blade, it does not bend and, with good sharpening, turns into an excellent scraper. But such a tool can also be made from a modern metal spatula, only for this you have to shorten the blade (this will make it more rigid), leaving only 2-3 cm in length.
But a scraper, even if it is a factory nozzle, is not always suitable for cleaning, and there is a practical confirmation of this. The author of this article had to face a situation where the cement-sand plaster in the bathroom was painted with oil paint.
So, the coating had to be removed with a hatchet, centimeter by centimeter (the paint smeared from the scraper), which took two days when two people were working!
Perforating chisel, shovel and lance
Some people use a nozzle on a perforator to remove paint, but this method is too ineffective and the main reason here is the impact force, due to which the plaster is more destroyed than its coating. And this cannot be avoided, even if you sharpen a chisel or a blade very sharply. they will cut even more deep into the surface of the wall, and not pry off a thin layer of coating.
The only option when this method brings tangible benefits is when the wall is painted with nitro-enamel. there, from the force of the impact, layers small in area simply fly off and after that the surface will only need to be processed in places with a spatula.
No matter what they say or come up with, the most reliable and proven method at the moment is the manual method of removing paint. here you will not miss a single millimeter of the coating, and, moreover, you will do it efficiently. The main problem of cleaning the surface with your own hands is a very low productivity and a huge laboriousness of the process, since the layer is not always removed easily, one can even say that easy dismantling is an exception to the rule.
Very often you have to scrape or knock down the surface literally one centimeter at a time, since the old paint holds very well.
Often, drill bits are used to remove paint, although, exactly the same, only with a different mounting method is put on an angle grinder (angle grinder).
Such a device is made in the form of a rotating brush with metal bristles, and while the wire is new (not bent), the processing is quite effective, but not for any paint. it happens (especially with oil coatings) that the metal bristles are not able to peel off the paint, but only smoothes it over the surface.
For such complex coatings, it is better to select brushes with a shorter nap, then the grout turns out to be tougher, although even such actions do not always provide one hundred percent cleaning.
At the moment, many consider the best attachment for automatic cleaning to be a chain on a rod, which is inserted into a drill instead of a drill (the price of such a nozzle is perhaps the lowest). During operation, the drill is held along the plane of the wall and the chains methodically and with high speed beat on the surface, breaking the paint on it.
Advice. After processing the surface with any nozzle in an automatic way, it is best to go through the scraper again, especially if the instructions for installing the cladding require a clean rough base.
Removing adhesive tapes
Another problem that repairmen face is removing adhesive tapes from the surface (those on which moldings and emblems are attached).

If earlier they were removed mainly by manual scraping, spending a lot of time, nerves and not entirely censorship expressions on this, now they can be quickly and efficiently removed with the help of special rubber circles in a matter of minutes.
It is desirable to operate at rpm 2000-4000. Too high revolutions and strong pressure of the sander can lead to overheating of the paintwork, so be careful.
Cleaning is carried out with confident reciprocating movements with moderate pressure to the surface. There is a direct relationship between the pressure on the wheel and the processing speed: the stronger the clamp, the higher the processing speed. However, at the same time, the circle itself will wear out faster. Therefore, do not press too hard on the clipper.
Hold the sander at a slight angle (15-20˚) for effective sanding.
Smooth the boundaries of the transition of the metal into the old paintwork to the most smooth state.
Remember to switch the tool on and off over the work piece. First attach the machine to the surface, then turn on.
Do not use the end face. this can lead to premature wear or damage to the wheel.
Observe the recommended rpm for each lap. If the recommended rotation speed is exceeded, the wheel will quickly wear out and lose its abrasive properties.
To process the paintwork before the subsequent filling, use the P80 gradation discs in the main area of the defect and P150 in the peripheral.
When sanding surfaces that have already been repaired and have thick layers of putty masses on them, the main task will be to get to a reliable coating layer. Indeed, as a result of damage and deformation of the element, the elastic metal could lose its adhesion to the inelastic filler. Sometimes there may be no visible signs of this, however, after you start sanding, all this ins and outs (cracks, peeling of the putty) are found.
Here our surface is already shining with a metallic sheen and treated with sandpaper for better adhesion of subsequent layers. It’s time to start filling the damage. About this. next time.

What nozzle is needed for removing paint from the walls
Almost all craftsmen will agree that it is much easier to build something new than to repair the old one, since you have to get rid of the old finish, which takes up extra time and effort. So, to prepare the surface for painting, you may need a paint stripper, which can be powered by an angle grinder, drill, hammer drill or simply by hand.

Anti-gravel coatings are a headache for many bodybuilders, as most abrasives are quickly clogged with particles of this synthetic rubber coating. However, there are still materials on the market that will help to cope with anti-gravel. special scraping discs based on bulk polymer fibers. At Sia they are called siastrip and have a gradation K040. At 3M, these are Clean Strip discs.
The rough structure of these discs ensures trouble-free removal of old anti-gravel coatings, while they are almost not clogged and heat up less. In terms of efficiency and durability, such circles surpass even metal brushes, and their size, shape and elasticity allow you to work in the most inconvenient and hard-to-reach places.

The operating speed of siastrip discs should not exceed 6000 rpm. Optimal. 3500. Work is carried out by the end part of the circle.
These circles also have a variety. sia-powerstrip circles. The working material on these discs is applied in a circle, which allows you to work faster and over large areas. Recommended working speed. 6000 rpm.

In soft attachments for drills, felt, felt, twisted threads, woven materials and foam rubber are used as working material. As a rule, such a tool is used for polishing metal, wood and paints and varnishes, including those with polishing pastes and suspensions. Soft tips are disc, ball, cylinder shaped and are attached to the shank with two clamping washers. One of the most common examples of their use in everyday life is polishing car paintwork with a drill and foam discs.
Abrasive end nozzles for drills are one of the varieties of cones. a locksmith tool that is used for manual grooving of profile surfaces, expanding holes and removing excess metal in hard-to-reach places. Such a roller cutter is a cylindrical shank, at the front end of which an abrasive head is pressed. And the name “face” is associated with the fact that processing with such a tool is most often performed in the perpendicular direction. End bits are available with a wide variety of heads: round, conical, cylindrical, parabolic, etc. Therefore, you can always choose a cutter, the geometry of which is most consistent with the processed profile. The material of the abrasive heads is various grades of high hardness emery stone. In a fixed drill, cylindrical cutters can be used to sharpen bench tools.
