Emery paper is widely used for preliminary and finishing processing of various materials. It can be wood, metal, plastic or protective coatings. Surface grinding is of particular importance in the woodworking and furniture industries. The final type of processing largely depends on its quality.
This material has a gradation in grain size. The choice is dictated by the task. Coarse-grained paper is suitable for removing large volumes of material or rough finishes. Finishing requires the finest grinding of the abrasive component, after which the surface can be polished.
What it is
This type of sandpaper is a liquid composition that includes special components. It is used for processing various surfaces in preparation for further decoration. Do not confuse it with polishing pastes, usually containing abrasive components.
Composition
The processing material contains three main components:
- naphtha;
- ethyl acetate;
- ethanol.
Essentially, all of these substances are powerful solvents. Ligroin belongs to heavy gasolines, ethyl acetate is a type of essential alcohol, and ethyl alcohol acts as a "classic".
Considering the composition, mainly liquid sandpaper is used to remove paintwork, oil or wax. All of them are used to give the surface a glossy sheen.
After using the solution, the treated area is not only completely exempted from the old finish, but also gets some roughness. This makes it possible for high-quality application of a new coat of paint or other finishing composition.
to contents ↑Pros and cons
The main disadvantage of using this material is the inability to level the surfaces. Its main purpose is to remove old paintwork and other finishing coatings.
However, this material has important advantages:
- minimum physical effort during work;
- lack of dust;
- ease of application.
Most often, liquid sandpaper is used to process wooden surfaces, but it is also used in other areas.
Safety precautions
As with any other job, using this material, you must follow the safety rules. This requirement is important because aggressive chemicals are included. In order not to harm health, the material can be used subject to the following conditions:
- people in contact with the composition must be protected by respirators, gloves and special clothing;
- ventilated area where work is carried out;
- after completion, the container with the solution must be carefully closed and rinsed all the used tool.
Observing these rules, you can work with the material completely freely.
to contents ↑Time
Using classic sandpaper, especially with manual sanding, can take a lot of time before the final result is obtained. The complexity increases in proportion to the area of the treated surface. For this reason, liquid sandpaper has another important plus - the ability to save time.
Using this material allows you to speed up the process of removing old coatings. It is enough to prepare the surface, having cleaned of dirt and dust, apply the solution, let the product dry, clean it again and you can apply a new coating. A base prepared using the composition will have increased adhesion.
to contents ↑Time is also saved when machining small parts or surfaces with complex geometry. It is quite difficult to carry out high-quality grinding in hard-to-reach places using ordinary sandpaper. However, the liquid composition avoids these inconveniences and obtain a qualitative result.
Cost
The price of this material relative to traditional analogues is affordable and is about 150 rubles per liter capacity of the composition. When calculating the budget, it is worth considering the volume of the project and the time for its implementation. If you want to get the treated surface as quickly as possible, the choice of liquid sanding paper is obvious.
If time suffers and there is no requirement to observe increased sterility in the room, then you can give preference to classic sandpaper. Otherwise, it is better to prefer its liquid counterpart.
