Common Challenges with uPVC Solvent Cement — And How to Fix Them

Plastochem uPVC solvent cement is a high-performance adhesive engineered to create strong, leak-proof bonds between uPVC pipes and fittings. It’s the preferred choice for professionals and homeowners who want flawless, long-lasting installations.

However, like any specialized product, getting the best results requires proper use. When applied incorrectly, common issues can crop up — from leaks and weak joints to messy finishes. Here’s a look at the most frequent problems people encounter with uPVC solvent cement and simple ways to prevent or fix them.

Top Issues & Solutions

🚫 Pipes Not Sticking Properly

Why it happens:

• Pipes or fittings were dirty, oily, dusty, or damp.

• The cement was applied unevenly, too heavily, or too lightly.

Quick fix:
Always clean and dry the surfaces thoroughly before applying the cement. Use a primer if needed to prep the surface for optimal bonding. Apply an even coat with a brush to ensure full coverage.

💧 Leaks at the Joint

Why it happens:

• The cement didn’t have enough time to set.

• Pipes weren’t pushed and twisted together fully.

• Pipes and fittings weren’t the right match in size.

Quick fix:
Push and twist the pipe firmly into the fitting and hold for at least 30 seconds. Then, allow the joint to set for 15-20 minutes before water testing. Always check that pipe and fitting sizes match perfectly.

⏳ Cement Dries Too Quickly

Why it happens:

• Exposure to air or hot weather causes the cement to harden before use.

Quick fix:
Keep the lid tightly closed when not in use. Work quickly, applying cement in small sections. In hot conditions, work in the shade or during cooler hours.

😬 Excess Cement Spills

Why it happens:

• Too much cement was applied, causing it to squeeze out when joining.

Quick fix:
Use only a thin, even layer of cement. Immediately wipe away any excess with a clean cloth before it sets, for a neat, professional finish.

🛠 Weak Joints After Drying

Why it happens:

• The pipes weren’t held together long enough.

• Old or expired cement was used.

Quick fix:
Hold the joint securely for at least 30 seconds. Always check the cement’s expiry date — fresh cement ensures a strong bond.

❄ Slow Setting in Cold Weather

Why it happens:

• Low temperatures slow down the curing process.

Quick fix:
Work in a warmer environment if possible. Otherwise, allow additional time for the cement to fully cure before testing the system.

🌬 Strong Odor or Fumes

Why it happens:

• The solvent in the cement releases fumes during application.

Quick fix:
Use the cement in a well-ventilated area. Open windows or use a fan. For sensitive users, wearing a mask can improve comfort.

🔍 Cracks Near the Joint

Why it happens:

• Excess force during assembly or too much cement may stress the pipe.

Quick fix:
Apply steady, gentle pressure and avoid overloading with cement. Just enough to cover the joint is all you need.

🙌 Difficult to Clean from Hands or Tools

Why it happens:

• The cement bonds quickly to skin and equipment.

Quick fix:
Wear gloves to protect your hands. Wipe tools immediately after use to prevent cement from hardening on them.
