Construction Sealants are essential materials used for sealing joints, gaps, cracks, and connection points in buildings and industrial structures. They help maintain effective sealing where joints may experience movement, moisture, weather exposure, vibration, or regular operational stress.
Choosing the right Construction Sealants is important because different joints and substrates require different performance characteristics. Depending on the application, sealants may be used for expansion joints, construction joints, industrial floors, façades, precast structures, metal-concrete joints, and other movement areas.
Kangaru Polymers, an experienced Construction Chemical Manufacturer, offers different sealant technologies including polyurethane, polysulphide, acrylic, and epoxy-polyurethane systems for specific construction and industrial applications.
What Are Construction Sealants?
Construction Sealants are materials applied into joints, gaps, cracks, or connection areas to create a continuous sealing layer. A suitable sealant can accommodate movement while maintaining adhesion to the required surface.
Joints in buildings and industrial structures can expand, contract, or move because of temperature changes, structural movement, vibration, or operational conditions. Construction Sealants help seal these areas while allowing the required level of movement.
The right Joint Sealant should be selected according to the joint type, substrate, movement, environmental exposure, and required performance.
Types of Construction Sealants
Different construction applications require different types of sealant systems. Kangaru Polymers provides several technologies for specific joint sealing requirements.
1. Polysulphide Sealants
Kangaru Polymers offers Kankol 625 P and Kankol 625 G, which are two-component polysulphide sealants.
These Construction Sealants are listed for applications such as concrete road joints, industrial floor joints, and expansion joints. They provide properties including elongation, UV resistance, cohesion, adhesion, weatherability, and resistance to flame and fuel.
Polysulphide systems can therefore be considered for applications where joint movement and environmental exposure are important factors.
2. Polyurethane Sealants
Kankol PU is a single-component polyurethane sealant available in grey and white.
This PU Sealant is designed for applications including industrial concrete floor joints and expansion joints. Polyurethane sealants can be suitable where flexibility, adhesion, and movement accommodation are important considerations.
The final selection of a PU Sealant should depend on the joint design, substrate, movement requirements, and project conditions.
3. Acrylic Sealants
Kanfill is a single-component acrylic sealant available in different RAL shades.
It is suitable for applications including metal-concrete joints and wall cracks. Acrylic-based Construction Sealants can be considered for appropriate joint and crack sealing applications where the product’s characteristics match the project requirement.
4. EPU Sealants
Kankol EPU is a two-component epoxy-polyurethane sealant available in different RAL shades.
It is listed for floor joints and metal floor joints. This type of Joint Sealant can be selected according to the substrate, joint condition, exposure, and required performance.
Applications of Construction Sealants
Construction Sealants are used across residential, commercial, industrial, and infrastructure projects. Their application depends on the type of joint, substrate, movement, and environmental conditions.
Common applications include:
- Expansion joints
- Construction joints
- Concrete road joints
- Industrial floor joints
- Metal-concrete joints
- Metal floor joints
- Wall cracks
- Façades
- Precast structures
- Movement areas
For industrial projects, Industrial Sealants may be required in areas where floors and joints are exposed to regular movement, traffic, or operational conditions.
Similarly, façades and precast structures may require a sealant selected according to movement and substrate compatibility.
Benefits of Construction Sealants
The performance of Construction Sealants depends on the formulation, substrate preparation, joint design, and application method. A properly selected sealant can provide several benefits.
Movement Accommodation
Certain sealant systems offer flexibility and elongation, allowing them to accommodate movement within suitable joints.
Strong Adhesion
Good adhesion helps a Joint Sealant remain bonded to the intended substrate and maintain sealing performance.
Weather and UV Resistance
Some sealant systems provide UV resistance and weatherability, making them suitable for specific exposed applications.
Surface Protection
By effectively sealing joints and connection points, Construction Sealants can help reduce unwanted pathways for moisture and environmental exposure.
Application Versatility
The availability of polyurethane, polysulphide, acrylic, and epoxy-polyurethane technologies allows construction professionals to select a system according to specific project requirements.
How to Choose the Right Construction Sealants?
Selecting Construction Sealants should begin with an assessment of the actual joint and site conditions.
Consider these factors:
- Joint type: Determine whether the requirement involves an expansion joint, construction joint, floor joint, road joint, or another connection area.
- Substrate: Identify whether the sealant will be applied to concrete, metal, precast elements, or another suitable surface.
- Joint movement: Evaluate the expected expansion, contraction, vibration, or structural movement.
- Environmental exposure: Consider UV radiation, moisture, weather, chemicals, traffic, and temperature variations.
- Application area: Industrial floors, façades, road joints, precast structures, and building joints can have different requirements.
- Sealant technology: Select polyurethane, polysulphide, acrylic, or EPU technology according to the application.
- Application procedure: Proper surface preparation and application are important for achieving the intended performance.
- Technical support: For project-specific applications, professional technical guidance can help with product selection.
Working with an experienced Construction Chemical Manufacturer can make the selection process easier by considering the substrate, joint condition, exposure, and project requirements.
