When talking about sealing seams in a bathroom or gluing objects to a smooth glossy surface, there is no better option. than silicone sealant.
This material provides a high-quality, reliable, and most importantly waterproof durable connection. We will describe in detail its varieties in this article, and we will study in detail the main characteristics and method of application of silicone sealant.
Soft and Plastic silicone sealant is produced from the hardest material that occurs in nature in the form of sand - this is silicon.
Polymers are made from this material, it is on their basis that silicone is made. The starting material also determines the properties of this sealant. Below we will consider them in more detail:
The sealant is also well used for sealing ceramic joints, as well as metal, concrete, wood, glass, plastic and other surfaces.
Studying the characteristics and properties of various types of sealants, it is necessary to pay attention to the special additives used in their production.
There are four types in total:
These additives significantly increase the performance of silicone sealants and their area of use.
According to their classification, silicone sealants can be divided into two groups, which in their the line can be divided into several subgroups, i.e.
two-component and one-component silicone sealants . Two-component sealants are used, as a rule, in manufacturing, and one-component sealants are used in construction and repair. Let's consider this group in more detail.
One-component sealants can be classified according to their chemical composition.
They are of the following types:
The production is based on acetic acid, and during the hardening process you can see for yourself by smelling a specific smell. Sealants of this class are versatile and relatively inexpensive. The marking goes with the letter "A". Their disadvantages are considered incompatibility with non-ferrous metals, since they cause accelerated development of corrosion in them. It is impossible to use them with marble, in the production of which alkali is used.
In addition, all sealants can be classified according to purpose.
A particularly striking representative of this classification can be called sanitary silicone sealant . Its purpose is to seal all threaded water connections, seal shower cabins and bathtubs, as well as other plumbing elements.
An adhesive sealant can also be distinguished, which is often used for the production of glass products, for example, aquariums. In addition to its direct purpose, this silicone has increased strength and resistance to stress.
All sealants of this class differ in color.
Standard color is considered transparent, but white or colored silicone sealant is possible. You can easily buy this sealant on the construction market and use it successfully in repair or construction.
There is nothing difficult in using silicone sealant. In order to seal the seams, you will need a sealant gun, on which a special tube is installed. It is quite simple to open the package, it is enough to cut off the tip of the spout with a sharp knife, and then screw a special dispenser onto it.
To adjust the volume of the sealant supply, the dispenser must be cut off in a strictly defined place.
Silicone sealant should be applied to a well-dried surface free from dust and dirt.
It is worth noting an important detail - silicone sealant will never stick to a wet coating.
An exception can be considered a special silicone sealant, which is used only in a humid environment. Excess sealant is removed from the surface with a wet cloth, and from hands with soapy water.
After the silicone sealant has hardened, it can only be removed mechanically. If the layer is thin enough, it can be removed with a solvent.
We have described the basic principles of working with silicone sealant. You can also say a few words about precautions and safety precautions when working with a sealant. When working and applying silicone sealant, seal all decorative surfaces with masking tape in advance.
This will prevent them from getting dirty. Also, when working, follow the safety precautions written on the sealant can.
In case of contact with eyes, rinse immediately with plenty of cold running water and seek medical attention.
