Long-Lasting Solution For Cracks and Gaps in your house


The properties and many benefits of sealants are often misunderstood, and they are mostly only used as quick fixes when an issue arises. On the other hand, if sealants are combined with other waterproofing and painting products, they will yield far better results than any quick fix solution. 

What is a sealant?

Sealant is a product mostly used in construction to stop liquids and other substances from passing through the surface of materials like joints and openings. They can also prevent the passage of air, sound, dust, and insects. Non-flammable sealants can also act as a fire-stopping component. 

They are typically used to close openings between spaces that are too small for other materials such as concrete, timber, or mortar. While some sealants have adhesive qualities, they are quite different from adhesives in that they tend to have lower strength and higher elongation. This means that they have more flexibility between surfaces with different properties.

Typically in traditional methods of home construction, huge, bulky walls and drainage channels are set up to absorb and shed water before it reaches the inner surface. In modern architecture, however, these huge, bulky aspects are eliminated in favour of airy, minimalistic designs that utilise lightweight masonry walls, rainscreens, renders, and curtain wall systems. All of these materials rely on sealant joints to provide air and weather seals while making room for building movements such as thermal expansion, settlements, etc. 

Typically, the external wall is built with masonry to fill spaces in the concrete frame containing slabs, beams, and columns. The plaster in them often develops cracks, allowing for seepage of rainwater from the external to the internal wall. Cracks in plaster can lead to water seepage in the exterior foundation wall as well. It is therefore necessary to have high-performance waterproof coating that covers the surface and bridges the cracks to prevent seepage of water from the external wall to the interiors of the building.


Basic functions of a sealant

  1. It helps fill gaps between two or more surfaces.
  2. It acts like a barrier to give adhesion to a surface.
  3. It maintains sealing properties for the expected lifetime, service conditions, and environments.

Matching the most suitable sealant to the surface materials (i.e. one that will have adequate bonding properties and be flexible enough to tolerate movement), ensures these properties and functions of a sealant can be achieved. 

Types of sealants

Water-based sealants

Mostly favoured for residential use because of the ease of application and ability to adhere to most substrates. These can be painted on and are suitable for situations where gaps are very small and movement is minimal.


Acrylic sealants

These are UV-stable, making them suitable for exterior applications. Also, they do not shrink easily and are known to have superior properties compared to other sealants.
