How to remove sealant from the baseboard

How to wipe silicone sealant off the tile?

Silicone sealant is very often used in construction or repair work. It is applied to the surface in a liquid state, but it tends to harden quickly. In this regard, there is a problem of rubbing encrusted sealant off various surfaces.

Why and how is silicone used?

Of course, it is best to remove the excess of this substance immediately after using it. But if that moment is missed, don't despair. Cured silicone sealant can also be removed, washed, and scrubbed even if you have to do it in the bathroom or kitchen where the tiles were laid, and there is a risk of damage to the surface during cleaning.

This substance will allow you to perfectly fill the space between the wall and the tile., all kinds of joints and seams, such a composition perfectly seals the space between the tiles, as well as the surface to which it is attached, preventing the ingress of dust, liquids and dirt. This, in turn, does not allow various fungi and molds to develop in the room.

But over time, the traces of the selected sealant will become contaminated, giving the room a sloppy look. Then it is necessary to wash off the remains of the old substance.

In fact, the dried sealant is quite difficult to remove as it sticks very tightly. But there are several ways to solve this problem.

There are three ways to clean the surface of the gasket composition:

  • Mechanically. You will need special tools: a knife, a construction spatula, a sharp razor, soda or salt in burlap, a kitchen wire mesh.
  • Chemically Special chemical agents are used that dissolve and destroy sealants. Here it is necessary to use means for individual protection, and it is necessary to observe precautionary measures. These drugs include "white spirit" or gasoline, solvents, "Penta-840", Dow Corning OS-2.
  • Combined. It is more effective because the above two methods are used right away. Using this method, the composition can be removed as soon as possible.

You need to start editing. Use a stationery knife or handy razor to remove a thick layer of sealant. Then apply the solvent for several hours. If the silicone is transformed into a gel-like substance, it is more convenient to remove it.

To do this, pry the edge with a knife and remove the solid tape. If a piece of tape breaks, you'll have to start at a new edge.

It is important to ensure that the surface of the tile is not damaged and that no sharp objects are injured.

Next, rinse the surface with water and wipe it with a dry cloth. Remove small residues of silicone. If it is eaten deep into the surface of the tile, there is no need to scrape it hard so as not to irreversibly damage the surface. It is necessary to act gradually and carefully. Remove or erase the composition of the tile is not difficult.

When using a chemical composition to be applied to the ears with a cotton swab or stick for 30 minutes, dull traces of the preparation can remain on the tile, they are removed with a degreaser. Then the surface is washed with water.

Before using any particular drug, a test should be carried out on a small area of ​​the surface in order to avoid unpleasant moments, since some tools are too aggressive for the material from which the tile is made.

All drugs come in three forms: aerosol, paste, and liquid. Aerosols should be shaken and copiously sprayed onto the sealant before starting work. It is convenient to apply the paste with a spatula and completely cover the areas to be cleaned. The liquid should be moistened with a cloth or sponge and process sealant with it.

Dow Corning OS-2 is a fairly mild substance that hardly damages the surface of the tile, but is non-toxic. Under its influence, the sealant becomes soft and easily removed.

"Penta-840" has a similar effect, but with prolonged use it can destroy silicone and damage the surface of the tile. This should be taken into account when using. In addition, "Penta-840" is perfect for cleaning the old sealant.

Special precautions should be taken when using the solvent; it is a flammable and toxic drug, the vapors of which are narcotic. Therefore, it can only be used in a well-ventilated area and with due consideration of personal protective equipment.

Specialized drugs can be bought at any hardware store.

All of them are divided into two groups:

  • Two-component mainly used in manufacturing or construction;
  • One-component - they are designed for removing silicone sealants from small areas and have several variants.

70% acetic acid is used to dissolve the acidic form of silicone. Alcohol types of sealant perfectly removed by the same composition: medical or technical. Sealants on a neutral basis can be treated with acetone, gasoline or "white spirit".

Of course, all of these specialized chemicals aren't cheap. As a result, there are simpler and cheaper methods of cleaning silicone sealants. For example, regular acetone. It should be applied to the areas that need to be removed and a piece of cloth dipped in acetone for about 1 hour; silicone will turn into a jelly to be removed in large pieces or all at once.

Vinegar can also be used. Small residues of sealant that may remain on the tile surface after cleaning can be removed with the help of kitchen wire netting, burlap. Baking soda put in a linen bag, or common salt soaked in water on a damp cloth will work well. Such savings are suitable for sensitive coatings that can suffer from more aggressive drugs.

You can try heating the sealant to a high temperature: from 400 degrees. In this case, the silicone softens and can be easily removed with a conventional sponge soaked in detergent.

It happens that the treated sealant does not remove the entire strip. Most often this happens due to an incorrectly chosen detergent or the poor quality of the sealant itself. In this case, you should process the silicone layer several times until it dissolves and peel off.

If it is known on what basis the sealant, then it is more logical to use the appropriate means to remove it, otherwise you will have to choose the drug at random and experiment. To avoid this, it is better to make a note beforehand about the sealant used in this room.

The tile can have a porous surface. To clean it will be much more difficult because of the uneven base. The task can also be made more difficult by the fact that the material is not covered with enamel, since in this case the silicone is much stronger and digs deeper into the surface of the tile. To clean the porous surface of ceramics, the process must be divided into several stages and repetitions: apply solvent to the tubercles and cavities, carefully remove the softened layer and reapply the liquid. Perform the sealant removal process.

Safety precautions

A few precautions should be observed when working with a silicone sealant.

It is necessary to use rubber gloves to protect the skin of the hands from getting substance on them. The room where repairs are carried out should be regularly and well ventilated.

Whenever you apply a sealant, you should immediately wipe spilled liquids and drips off the surface with a damp sponge or cloth dampened with soapy water, as this problem is much more difficult to resolve once it has hardened.

Before applying the substance to the grout, you can cover the uncured surface with tape. This not only preserves the clean surface of the tiles, but also the contours between the tiles.

When using an aerosol cleaner, you need to be very careful. The product is sprayed around the perimeter and care must be taken not to fall on the skin or the clean surface of the tile, which can be damaged: the liquid can affect the paint and enamel. Some types of surfaces can blister or crack. To avoid this, cover the area of ​​the tile that should not be edited.

Before doing any work on applying or removing silicone sealant, you need to decide on the method of cleaning: you will use a mechanical method, or you will have to resort to chemical preparations.

In any case, you will need the following tools:

  • Rubber gloves;
  • Respirator;
  • Fan;
  • Spatula;
  • Office knife, razor blade;
  • Masking tape;
  • Tassel;
  • Cleaner and instructions for it.

All of the above methods are used to remove old putty. Everyone decides for himself which method and which drug to use.
