At 7Mart, you can explore silicone sealants, PU joint sealants and other sealing products for suitable construction projects. Whether you work as a contractor, builder, fabricator or maintenance professional, our catalogue helps you compare available products and find the right solution.

Explore Silicone Sealants for Construction

Silicone sealants help seal window perimeters, glazing joints, curtain walls and exterior gaps. Depending on the formulation, they also provide flexibility and weather resistance for compatible building materials.

When choosing a construction silicone sealant, first identify the substrate and application. Then check the joint movement, curing system, colour and recommended application conditions. For example, neutral-cure silicone may suit certain glazing applications. However, always check the manufacturer’s technical data sheet before making your choice.

PU Joint Sealants for Building Applications

Polyurethane (PU) sealants offer flexible sealing solutions for selected construction joints. Contractors often consider them for applications that require movement accommodation and durable joint sealing.

Before selecting a PU construction sealant, examine the joint design, substrate and environmental conditions. In addition, follow the manufacturer’s recommendations for surface preparation, application and curing. This approach helps you choose a product that matches your project’s requirements.

Concrete Joint Sealants and Weatherproof Sealing

Concrete joints in buildings, warehouses and other structures often need protection against weather exposure and unwanted water entry. Therefore, choosing the correct concrete joint sealant matters for the long-term performance of the joint.

First, determine the joint dimensions and expected movement. Next, check the product’s compatibility with concrete and its resistance to the expected environmental conditions. Although some sealants offer excellent weather resistance, not every product suits continuous water immersion or every waterproofing application.

Frequently Asked Questions

What is a construction sealant used for?

Construction sealants help close gaps and seal joints in buildings. For example, contractors use suitable formulations for glazing, window perimeters, façades and concrete joints. However, each application requires a compatible product.

Which sealant is suitable for concrete joints?

The right concrete joint sealant depends on joint movement, dimensions, exposure and required performance. Therefore, review the product’s technical data sheet before selecting a suitable formulation.

What is the difference between silicone and PU sealant?

Silicone and polyurethane sealants offer different performance characteristics. Silicone commonly serves glazing and weather-sealing applications, while certain PU formulations suit flexible construction joints. Nevertheless, the correct choice depends on the product specification and project requirements.

Where can I buy construction sealants in Pakistan?

You can browse construction sealants at 7Mart and compare available products, pack sizes and current prices. Before ordering, review each listing to confirm suitability and stock availability.

How do I choose a weatherproof sealant?

Start by identifying the substrate and exposure conditions. Then check the product’s weather resistance, movement capability and compatibility with the intended application. This helps you choose a suitable solution for exterior sealing.

Can I use one construction sealant for every joint?

No. Different sealants serve different purposes. For instance, glazing silicone, concrete joint sealant and general-purpose adhesive sealant may have different performance characteristics. Therefore, always select a product that matches the intended application.
