How to Use UPVC Solvent Cement: Complete Step-By-Step Guide

UPVC Solvent cement is an essential thing in the plumbing system. It helps to create strong, durable joints in pipes. UPVC solvent cement stands for Unplasticized Polyvinyl Chloride solvent cement. It is a specialized adhesive used highly in plumbing and construction bonds, mainly for PVC piping and fittings. It is the chemical cement that works by chemically dissolving the surface of UPVC components and creating a strong and permanent bond.

UPVC solvent cement is not a traditional adhesive. It is a special cement and needs a special process to use. Here is the step-by-step guide on how to use UPVC solvent cement-

Step 1: Gather All the Necessary Materials

Start by collecting all the necessary things like UPVC pipe, UPVC solvent cement, applicator, brush, cutter, etc.

Step2: Prepare the Pipe

Now, prepare the pipe or fitting that you want to fix. You can use a plastic cutter to cut the UPVC pipe. Make sure to cut the pipe in the correct size.

Step 3: Prepare the Surface

Before applying the solvent, it is important to clean the surface carefully.  Clean both the pipe and the inside of the fitting. You can also use a suitable cleaner for cleaning. Make sure, every dirt, grease, and contaminant is properly cleaned.

If you used any wet clothes or something, make sure it dried out completely.

Step 4: Apply the Solvent Cement

Once the surface is clean from both sides. Now, time to apply the solvent cement. Make sure to apply a generous amount of cement on both sides, the pipe, and the fitting. It is suitable to use an applicator or brush to apply the UPVC solvent cement.

Once the application is done on both surfaces, dip your applicator into the cement and apply another layer on it for better safety. It is suggested to apply it on an even surface, so there is no weak spot left on the pipe.

Step 5: Join the Pipes

Once you apply the solvent cement or reapply the solvent cement, quickly assemble the pipe. It is a quick cement, and typically takes five minutes only to start the process for adhesive.  Quick push the pipe and fitting, so that cement distributes evenly in the whole surface. It is suggested to hold it for a few seconds.

Make sure to check the pipe and bottom out inside the fitting hub secured completely.

Step 6: Cleanup Extra Cement

Once you join the pipe and fitting, it is good to remove excessive solvent cement. You can use some tissue or rug to clean it.

Step 7: Allow the Joints to Cure

Once the pipe and fitting at the joint. Allow them to dry out and settle down. It will take time. The recommended time depends on the size of the pipe and the environmental condition, but it is good to give some hours for proper bonding.

Tips for the Best Result of Using UPVC Solvent Cement

If you are using UPVC solvent cement for joining pipe fitting, here are the tips to get the best result-

• Work in a well-ventilated Area: Remember solvent cement emits fumes. It can be harmful if you inhale it. Hence, it is suggested to use it in the ventilator area or you can also use a mask.
  
  
• Check Expiry Date: It is suggested to use the expiry date of your solvent cement. If it expires, it does not work effectively and is a waste of your time. Hence, always verify the product's shelf life before using it.
  
  
• Avoid Overuse: Excessive using solvent cement does not give you a stronger bond. Instead, it weakens the bond. Only use a generous amount of solvent cement. Do not overuse it on the layer. You can wipe it off if you find it excessive.
  
  
• Store Properly: Once you fully use your UPVC solvent cement, then keep it in a cool and dry place. Make sure to close it tightly, so it does not evaporate or oxidize for future use.

Common Mistakes When Using UPVC Solvents

• Using too much or too little solvent: It is important to use the right amount of solvent for a strong bond. Do not use too much or too little solvent. Excessive solvent causes excessive softness in the material and the joint whereas little solvent causes weakened bonds and breakdown easily.
  
  
• Skipping surface preparation: Skipping surface cleaning gives you poor adhesion. It leads to leakage which is why always clean both surfaces properly and make sure all the residues are removed.
  
  
• Not allowing proper cure time: Giving a proper cure time is very important for a strong bond. When using UPVC solvent, patience is the key. Give it a few hours or days for a better or stronger bond.
  
  
• Using the wrong cement: For your UPVC pipes and fitting, make sure you are using the UPVC-specific solvent cement only. You cannot substitute it with PVC or CPVC cement. Always use specified solvent cement for specified pipes and fitting.

Conclusion

Using UPC solvent cement in the UPVC pipes and fitting gives a strong and durable connection. It is effectively used in plumbing systems, irrigation systems, industrial pipes, and many more. For effective results, it is important to follow all the guided steps like preparing material, cleaning your surface, using a generous amount of solvent cement, removing excessive solvent, and at last allowing proper curing time.

Frequently Asked Questions

1. Is UPVC solvent cement used for PVC pipes?

And:No, it is not suitable to use your UPVC solvent cement for PVC pipes. UPVC solvent cement is only ideal for UPVC pipes.

2. How long does UPVC cement take to settle down?

Ans: The exact timing depends on the external condition and length of the pipe. But within 15 minutes, the initial setting starts, and takes about 24 hours to properly settle down.

3. Can I use UPVC solvent cement indoors?

Ans: Yes, you can use UPVC solvent cement indoors but make sure to use it in the proper ventilation space.

4. Can I adjust the pipe after applying the cement?

Ans: Yes, you can adjust the pipe immediately after using the pipe. But do not adjust the pipe after five or 10 minutes.

5. How can I store my UPVC solvent cement?

Ans: After using UPVC solvent cement, close it tightly and store it in a dry or cool place.

6. What is the shelf life of UPVC solvent cement?

Ans: The typical shelf life of UPVC cement is 12 to 24 months. But it is good to check the product label for accurate timing.

7. What happens if I use excessive solvent cement?

Ans: If you use excessive solvent cement, it will weaken the joint and cause weak points to leak.
