Looking for Plumbers PVC-Primer

[doggie1955]

Has anyone seen this in Thailand, I know Thai's don't even know what it's used for... Been looking for it for some time now.

That is not used in Thailand, they use a clear glue that can be purchased at home pro or any buiders store.

SCG has a primer but very expensive. I by acetone at a chemical shop and prep using that.

You do not need a primer. Just score the male and female parts with a light sand paper and then apply solvent glue. Dead easy.

I after carefully putting a pickaxe through a PVC pipe I was able to mend the pipe again while the water was still flowing. Joint is still good four years later, admittedly not high pressure.

The purpose of the primer is to begin the chemical reaction that softens PVC and to provide an even prepped surface for the solvent cement. As you may know, PVC joints are not glued together exactly but fused through a chemical change. The softer the outer layer of your PVC, the better it will cement in your joint... So yes you do need it.

As you may know, PVC joints are not glued together exactly but fused through a chemical change. The softer the outer layer of your PVC, the better it will cement in your joint. This is how primer helps your joint strength.

In many states, plumbing inspectors will look for primer and only pass you if they see liberal use on all joints. Most primers are a vibrant purple color so that its use is evident, but there are also clear primers. If you're working on an inspected job, find out if that state requires the use of the primer. If it does, choose a brand that offers a colored primer that will be easy to see, and use it liberally beyond where the pipe will meet the socket. If the inspector can't see it, there's no point in using it.

When it comes time to apply your primer make sure you are 100% ready to prime AND cement. Primer is effective only when wet, so you need to move quickly once you begin. Usually, PVC jobs require about half the amount of primer as they do cement.

In short, the primer is your friend. It may not be completely necessary on all jobs, but we recommend you take all the precautions available to ensure your joints are leak-free and as strong as possible.

Joining PVC is considered call solvent welding.
You are making 2 pieces of PVC 1.
The job of the primer is to soften the PVC so when you apply the "glue" it will cause the 2 pieces to combine on a molecular level so the 2 are now 1.
Years back we used to do whole houses not using any primer, then we started using it, then the purple primer was required. The purple primer was a disaster as it would not allow the joints to set right and they would pull apart minutes later sometimes. Then they went away from that and back to the regular primer.
Joints made without primer could be easily taken apart with a hammer and flat head screwdriver

May be in the US of A but not in the UK or in Tingtong land as the video explains. Different countries different methods and materials.

There a right way and a wrong way of doing things... Watch how to do it the right way!

Not really, you have 2 pieces of PVC with a tiny amount of them bonded. It is quite easy to recover the fittings though the pipe section in the fitting is usually toast. All you need is heat, I've used a hot air gun, but there are a few other ways to get them hot enough here is an example

if you want really good joints then welded PPR is the way to go.

Anyone know anything about a primer and where to get it? 

 

Or anything alike this plast aid?
