The Importance of Construction Bonding Agents: Ensuring Durability in Harsh Climates Like Edmonton

By April 30, 2023May 6th, 2024No Comments

Construction bonding agents play a crucial role in ensuring that building materials stick together properly, forming a strong and durable structure. Bonding agents are used in a variety of construction projects, from repairing cracks in concrete to creating new structures from scratch. In this blog post, we will explore why bonding agents are important and the different types available, including latex bonding agents.

Why are bonding agents important?

Bonding agents are important because they create a strong bond between two materials that would otherwise not stick together well. This is important for several reasons:

  1. Strength: When materials are bonded together, they form a stronger structure than they would individually. This can make a big difference in the durability and longevity of a building.
  2. Adhesion: When materials are bonded together, they form a tight bond that prevents moisture and air from getting in between them. This can prevent problems like rot and mold from developing.
  3. Aesthetics: Bonding agents can also improve the appearance of a building by creating a smooth, even surface.

One specific application of bonding agents is in parging. Parging is a process where a layer of mortar is applied to the surface of a masonry wall. This layer of mortar can help to protect the wall from moisture and damage, but it needs to be applied properly to ensure that it sticks to the wall and remains durable over time. Bonding agents are often used in parging to ensure that the mortar sticks to the wall properly.


In climates like Edmonton, where the freeze-thaw cycles can cause significant damage to building structures, it is essential to use high-quality bonding agents to ensure the durability and longevity of building structures. By using bonding agents in parging and other construction projects, construction professionals can create structures that can withstand harsh weather conditions and last for many years.

When parging is applied without a bonding agent, the layer of mortar can easily crack and become dislodged from the wall due to the constant expansion and contraction caused by temperature changes. This can result in moisture infiltration and damage to the masonry wall, which can be costly to repair.

Types of bonding agents

There are several different types of bonding agents available for construction projects, each with its own unique properties and uses. Here are some of the most common types:


  1. Cementitious bonding agents: These are bonding agents that are made from cement and other materials. They are commonly used to bond concrete surfaces together.
  2. Epoxy bonding agents: Epoxy bonding agents are made from two-part epoxies that are mixed together before application. They are commonly used to bond concrete and other materials.
  3. Acrylic bonding agents: Acrylic bonding agents are made from acrylic polymers and are commonly used to bond concrete, stucco, and other materials.
  4. Polyurethane bonding agents: Polyurethane bonding agents are made from a two-part mixture of polyurethane resin and hardener. They are commonly used to bond concrete and other materials.
  5. Silane/siloxane bonding agents: Silane and siloxane bonding agents are made from a blend of silane and siloxane. They are commonly used to bond masonry and other materials.
  6. Latex bonding agents: Latex bonding agents are made from a blend of synthetic latex polymers and are often added to cement or concrete mixtures to improve their bonding strength and adhesion properties. They work by forming a thin layer between the two surfaces that need to be bonded together. This layer fills in any small gaps or imperfections in the surfaces, creating a strong, cohesive bond. Latex bonding agents can be used to bond concrete to concrete, concrete to wood, and other materials.

In conclusion, bonding agents play a vital role in ensuring the durability of building structures, particularly in harsh weather conditions like those experienced in Edmonton. By using high-quality bonding agents like latex bonding agents, construction professionals can create strong, cohesive bonds between building materials like parging, ensuring the longevity of structures and preventing costly repairs in the future.
