Commercial Caulking

Caulk or Caulking is a material used to close off joints or seams to prevent leakage in various structures and piping joints to ensure watertight or gas-tight integrity of those joints. Caulking is a general term used in any field of construction.  The earliest forms of caulk consisted of fibrous materials driven into the wedge-shaped seams between boards on wooden boats or ships. Water-tight seams and joints are also essential in underground piping.

Caulking compounds are sealing compounds used to fill gaps in buildings and other structures.

A caulking gun applies the product for accurate dispensing.  This component protects against water, dust, air and insects while providing thermal insulation, controlling water penetration and noise reduction.

Caulk is a flexible waterproof sealant applied to form a hard coating on a porous surface in buildings to provide a watertight cover. Caulks are relatively rigid when dry. There are many types of caulking available, but they are all derived from the four main bases of rubber, latex, silicone or polyurethane. The chosen product is determined by the surface or specific uses of the materials of the construction’s composition. Examples of caulking products include:


One of the two most popular types of caulk is silicone; the other is latex. Silicone features many advantages over different types of caulk, especially when weatherproofing your building. Silicone is exceptionally durable, particularly in direct sunlight and during rapid temperature fluctuations. Being very flexible makes it ideal in situations when you need to fill gaps that contract and expand (e.g. temperature changes). Silicone caulk dries quickly and will stay soft. However, silicone also has a few disadvantages. It is difficult to apply and does not adhere to every surface. Silicone is also almost impossible to paint, so if you need to match your caulking with the paint on your building, a different caulk is required. Acrylic latex silicone caulk is suitable for concrete and is more durable than butyl caulk and can last up to 25 years.

Preformed foam sealants:

These are used for weatherproofing around HVAC systems on the roof, as well as for gaps around windows, and it can be applied to many commercial building materials including, metal, brick and stone. This material is not only excellent for weatherproofing it is also superb for fire protection.

Preformed silicone extrusion systems:

Caulking, like many parts of a building, is likely to fail at some stage. In time, it can start to tear, crack and peel away. When this happens, it will compromise the weatherproofing your building. Preformed silicone extrusion systems have been developed to replace old caulking. These systems are suitable for sealing metal curtainwalls, skylights and windows. It’s an excellent option for commercial building owners who want an attractive weatherproofing system.

What are the differences between caulking and sealants?

Both caulk and sealants are used to fill gaps in building materials. However, caulk is quite rigid when dry, and sealants are made from a more flexible material making them appropriate for areas that experience expansion and contraction. Both are designed to unite two different surfaces together to control water, wind, sediment entry or accumulation. In some cases, a flexible product to give some mobility and other times a firm and solid product to resist damage are required.
