Sikadur 732 Epoxy Resin Bonding Agent

Sikadur 732 Epoxy Bonding Agent – Strong Bond Between Old and New Concrete

When carrying out concrete repair work, one of the most common problems is that the new concrete or repair mortar does not properly bond to the existing concrete surface. Over time, this can cause repairs to crack, debond, hollow, or fail completely.

.

Sikadur 732 is a professional-grade two-component epoxy bonding agent specially designed to create a powerful bond between old concrete and new concrete, repair mortar, screed, plaster, or cementitious overlays. It acts like a “super glue” for concrete, ensuring the new repair material becomes firmly attached to the existing substrate.

Widely used by contractors, engineers, and construction professionals, Sikadur 732 helps increase repair durability, reduce repair failures, and improve the lifespan of concrete structures. Contact Us Buildmate Home Living Sdn Bhd

💡 What is Sikadur 732?

Sikadur®-732 is a two-part epoxy bonding primer consisting of:

📦 Part A – Resin

📦 Part B – Hardener

Once mixed together, the product forms a high-strength adhesive layer that bonds old concrete to new concrete.

Unlike traditional cement slurry, Sikadur®-732 provides significantly stronger adhesion and better long-term performance, making it suitable for both structural and non-structural repair applications.

🔨 What Problem Does Sikadur 732 Solve?

Many concrete repairs fail because the new repair mortar cannot properly attach to the old concrete.

Common problems include:

❌ Repair mortar falling off

❌ Concrete patch repairs cracking

❌ Floor topping debonding

❌ Hollow sounding repairs

❌ Weak bonding between old and new concrete

❌ Water penetration through repair joints

❌ Premature repair failure

Sikadur®-732 is specifically designed to solve these issues by creating a permanent bonding bridge between existing concrete and new repair materials.

⭐ Why Use Sikadur®-732?

Imagine repairing a damaged concrete floor without using a bonding agent.

Even if the repair mortar is strong, it may eventually separate from the old concrete because there is no proper bond between the two surfaces.

By applying Sikadur®-732 before placing the repair mortar, you create a powerful adhesive layer that significantly improves bonding performance.

🏭 Why Contractors Prefer Sikadur 732

Many contractors previously used cement slurry as a bonding layer.

However, cement slurry can dry too quickly and may not provide sufficient bonding for demanding repairs.

Traditional Cement Slurry

❌ Lower bond strength

❌ Short working time

❌ Higher risk of repair failure

❌ Not suitable for critical structural repairs

Sikadur®-732

✅ Superior adhesion

✅ Structural-grade bonding

✅ Long-lasting performance

✅ Higher reliability

✅ Better repair success rate

For critical repairs, engineers and contractors generally prefer epoxy bonding systems such as Sikadur®-732.

⚙️ How Does Sikadur 732 Work?

Step 1️⃣

Clean and prepare the concrete surface.

Step 2️⃣

Mix Part A and Part B thoroughly.

Step 3️⃣

Apply Sikadur®-732 evenly onto the existing concrete using a brush or roller.

Step 4️⃣

Place fresh concrete, repair mortar, or screed while the bonding layer remains tacky.

Step 5️⃣

Allow the repair system to cure properly.

The result is a strong bond between old and new concrete that helps prevent future repair failures.
