Concrete surfaces can be considered one of the strongest and most durable
Concrete surfaces can be considered one of the strongest and most durable. In one way or another, they are also at risk due to temperature differences, exposure to moisture etc. These issues leads to cracks in concrete. Such defects not only spoil the appearance, but is also dangerous. This leads to moisture penetrating into them more easily, and excess fluid can affect the concrete leading to its destruction. Also, dampness may cause fungus or mold.
In such cases, a companion who will help reliably seal the cracks and seams will be a sealant for concrete. With this tool, you can firmly clog the holes and prevent moisture and gases from entering them.
Features
A sealant is a viscous substance that resembles a paste in its consistency. They are formed on the basis of polymers. In addition, there are differences in composition. So, for example, you can buy a sealant in which acrylic or silicone is added. Depending on what substances are part of this product, the way they are used changes.
These funds are characterized by a wide range of qualities. They have good water resistance, adhesion, impermeability, resistance to many negative environmental phenomena. If you use sealant correctly and accurately, the result will be the durability and strength of your work.
One of the most suitable means for removing joints in concrete is acrylic sealant. Silicone sealant is also suitable. They are highly resistant to various destructive environmental conditions.
n the process of carrying out construction work, concrete processing is a matter of paramount importance. It consists of most of the significant structures of the building: foundation, floor, walls. Needless to say, what happens if an excessive amount of fluid gets into the resulting cracks?
In this process, adhesion plays a special role, that is, the adhesion of different bodies. In our case, the treated surface and sealant.
Other surfaces suitable for processing:
- wood;
- tin;
- a rock;
- brick;
- ceramics;
- plastic;
- non-ferrous and ferrous metals.
Variety of sealants
There are so many concrete sealants and their classifications.
Sealants can be divided by their mode of action.
- As a result of their use, a strong impermeable film is formed on the base, preventing the penetration of external aggressors. Depending on the sealant used, the film can be either matte or glossy.
- They completely cover the hole and protect against various environmental conditions.
They differ in the components that are part of:
- silicone;
- acrylic;
- polyurethane;
- silicate;
- butyl rubber;
- bitumen;
Sealants can also be divided by the criterion of their readiness for use.
- Single-component or single-component. Such tools are already ready for use: they do not require additional intervention before work.
- Two-part or two-component. These sealants need preparation before work. Before applying them, it is worthwhile to study the technology written by the manufacturer on the packaging or bottle.
There are several more criteria by which types of sealants are formed.
According to the method of solidification:
- non-hardening (in properties they resemble rubber);
- drying out (harden in time);
- vulcanizing;
By the method of application:
- spatula (applied using a spatula);
- carpal (a brush is necessary for applying sealant);
- filling (special devices are used, for example, a gun).
Despite the fact that there are a large number of different classifications, most often sealants are divided into one-component and two-component ones. Therefore, their special properties would be more convenient to consider on the example of these particular sealants.
