Basically, when concrete slabs are exposed to the environment uncovered, they get stained and corroded. This is because they are porous to liquids and chemicals. However, these conditions are reversed when a sealant is applied on top of the slab surfaces. When applied, it blocks all the pores that the slabs uses to absorb water, other liquids, chemicals and salts making the surfaces impermeable to these materials. However, in order to have the application done properly, you need to have a concrete sealer sprayers that is of good quality.

Research conducted as well as information from cement manufacturers, dealers and companies indicate that when these surfaces get exposed to wet, freeze and thawing objects and conditions cause a rapid deprivation of the surfaces abilities. These surfaces are also affected greatly by alkali-silica and intrusion chemicals reactions as well as corrosions from steel reinforcements. The sealants are readily found in the market and are of different varieties.

In the past years, contractors used linseed oils and wax to provide protection for the surfaces. However, due to increased innovations, inventions, and technological advancement, powerful materials have been developed that provide protection for the slabs. One of the materials used is tropical sealants. When applied, they need the surface to be dry and clean so that proper adhesion can be attained.

Penetrating sealers are the other material type used. These materials can have adhesion either in dry or damp surfaces. They require proper matching with the porosity of the substrate so that they can penetrate properly on the surface for proper reaction. This reaction of the chemical and the substrate is what forms a film that blocks any penetration of moisture into the surface.

The sealants are usually composed of various components that contain the necessary properties to provide the barrier. The films that are formed on the surfaces are as a result of a compound known as acrylic resins. Another element that is closely related to this is the urethane systems. Additional compounds include silane and silicates which offer great molecular characteristics.

Silane is another compound used in the manufacture of these sealing materials. They have small particles characteristics and are ideal when penetrating sealants are required. Another element used in manufacture include silicates which have the same small particle characteristic. Materials with medium size particle characteristic include Siliconates. These compounds are water repellent, oleophobic and hydrophobic. These characteristics make these materials to wear once the substrate has is completely worn out.

All these protective cannot be applied without a sprayer or application device. There are various techniques that you can use to make sure that the application has been successful and that you have not destroyed your application equipment. First, choose the correct type of equipment or device to use, then read the instructions on the equipment. After you have read the instructions, choose the correct protective material to use.

Choose the right sealing material that adheres to the instructions on the pump. If the device requires either solvent or water-based sealing material, use the recommended material. Proper cleaning, storage, lubricating and maintenance is important so that the functionality of the device is maintained.
