The best PVC glue around!

PVC plastic can be found everywhere, from gutters to electrical conduit to water pipes, it’s possibly one of the most common industrial plastics used today.

As the leading supplier of PVC glue in Ireland, I thought it was time to offer some handy tips and tricks for gluing PVC pipe! So here goes…….

When sections of PVC pipe are joined, the individual lengths are literally welded together. We typically understand welding in terms of metal, but plastic can be welded too and luckily enough, PVC is a very easy plastic to weld. We don’t weld PVC with heat, we weld it with solvent cements!

To briefly explain, a solvent cement is a glue which consists of a small amount of plastic resin which is dissolved in a solvent. When a solvent cement is applied to the surface of the PVC pipe, the solvent contained within the cement, temporarily melts the surface of the PVC. Immediately after applying the solvent cement, the pipe sections are put together and a few seconds later, the melted PVC surface re-solidifies and forms a seamless and water proof joint.

And for gluing PCV pipe, there is only one glue which you should think about, and that is Weld On 725 Wet ‘R Dry.

Weld On 725 Wet ‘R Dry is the ideal choice for use on rigid and flexible PVC pipe and fittings. It is specially formulated for applications where conditions are wet and/or quick pressurization is desired. It was developed to answer specific needs in irrigation, plumbing, and/or pool & Jacuzzis.

The PVC gluing process appears quite simple, and it is, however if a mistake is made, the only solution is to cut the PVC before the joint and start again! Want to make wonderful PVC pipe joints? Let me show you how!

• Measure and cut. To ensure that the pipe will be fully seated in its fittings, measure the distance between the shoulders on the fittings at each end of the pipe. Transfer that measurement to the pipe and make a straight cut with a hacksaw. Scrape the inside of the cut smooth with a craft knife.
• Dry fit. Assemble everything to make sure the pipe is the correct length. On fittings such as elbows, position is critical, so make a reference mark from the pipe onto the fitting.
• Glue. Apply the Weld On 725 Wet ‘R Dry glue to the areas on the inside of the fitting and to the outside of the pipe.
• Push and twist. Slide the pipe into the fitting until it bottoms out against the fitting’s shoulder, then give it a quarter turn to spread the glue and speed its cure. If you’re attaching a fitting, push it in with the reference marks slightly out of register, and turn the fitting to align the marks. Hold for 30 seconds, then wipe up any excess cement with a dry rag.

And there you have it. We stock and supply Weld On 725 Wet ‘R Dry glue, in handy tins of 273 ml and 473 ml. The screw on cap contains a nifty application brush, so no need for a stringy mess.
