What equipment is needed to apply SABA sealants?

There are various methods for applying our sealants. The choice of using a sealant gun, pressure vessel or pump depends on the type of sealant, the quantity and the application. Various factors influence the choice of equipment. We discuss these three application methods in detail below.

Sealant Gun

Among our application methods, the sealant gun is the most common. This tool, often referred to as a caulking gun, is suitable for applying sealant from cartridges, sausage packs (400 ml as well as 600 ml) and canisters. Caulking guns can also be used to process 2-component systems, although this will require a forced action mixer in some cases.
 
A high-quality sealant gun includes a drip-free system that prevents flow after use, which counters leakage and contamination. Various models and types are available in different price ranges. We make a distinction between the following three types of caulking guns: manual, compressed air and electric.

Manual Sealant Guns

Manual sealant guns are perfectly suited for applying smaller quantities of sealant to joints. Manual caulking guns are relatively cheap, lightweight and allow for well-controlled application with a great deal of flexibility in movement. Another advantage is that a cordless caulking gun can be used anywhere, even on a scaffold. Keep in mind that manual use can strain the applicator’s hand.
 
For thicker sealants with higher initial tack there are special sealant guns with a delayed transfer mechanism to reduce the force needed to be exerted by the applicator.

 

Compressed Air Guns

Compressed air guns, also known as pneumatic caulking guns, are easy to operate. The biggest advantage of pneumatic caulking guns in comparison to manual caulking guns is faster application. This enables the applicator to complete more meters per day. The constant outflow ensures uniform application of the sealant.
 
However, a potential drawback is the compressor’s supply line, which can constrain mobility at the worksite. In other words, the distance from the compressor must be taken into consideration when this method is used.

 

Battery-Powered Caulking Gun

The battery-powered caulking gun is an excellent solution that ensures uniform sealant application. The cordless operation offers freedom of movement without the constraints of lines. This method combines the advantages of a compressed air gun, as well as a manual caulking gun. However, it is somewhat heavier and can be in a higher price range.
 
The ideal sealant gun for your project depends on the application, joint length and budget. Our experts are happy to help you choose the right equipment. Do not hesitate to contact us without obligation for custom advice.

Pressure Vessel

An often used sealant application method in the civil-engineering and environmental sectors involves the use of a pressure vessel. A lance is used to easily apply the sealant, for example to seal expansion joints at airports. This approach is ideal for more liquid sealants.
 
SABA has extensive experience in applying its sealants using a pressure vessel system. This method makes it possible to apply sealant over lengths of up to 1500 meters.
 
A major advantage of a pressure vessel in comparison to a pump is that the required equipment is relatively simple: all that is needed are a generator, pressure vessel and compressor.

 
 

Pump

An ideal sealant application method for largescale projects in the civil-engineering and environmental sectors involves the use of a pump. Compressed air, as well as electric systems can be used, to which large vessels can be connected. This technologically advanced method can be used to process joints up to a length of 700 meters per hour, which amounts to approximately five kilometers per day.
 
Aside from the impressive speed and efficiency, pumps also provide for a continuous flow. The possibility of using 20 to 200-liter IBCs reduces the frequency at which the packaging needs to be changed. Furthermore, this method provides better control over mixing 2-component systems. A drawback of this method is that mobility is constrained by hoses and that it requires an investment in a mobile pump.

Nozzles

Nozzles are an indispensable accessory in every application method. They are available in various shapes, such as V-shaped, round or angled. Choosing the right nozzle depends on various factors. Our specialists are ready to contribute ideas and help you find the ideal nozzles for your project.
