What is the best glue for laying track – Hornby or Peco, it’ll hold both

Today, I’m going to answer one of the most common questions that pops up in my mailbox and in the ModelRailwayEngineer community group. What’s the best glue to fix your track down? It may seem obvious but it’s not.

It’s a question that all railway modellers ask at some point. A £1000 question if you like, if I had £1 for every time I’m asked, etc.

For most of us, whether we’re working in N, OO, HO or any of the other common track gauges, we default to good old PVA — white wood glue. I certainly use this a lot and have suggested it here many times before and for good reason. PVA, Polyvinyl acetate to its friends, is:

  • Cheap: it can be bought in bulk quantity for very little.
  • Easy to remove: track fixed down with it can be lifted relatively easy later.
  • It’s easy to clean off track, even when ballasted, to reuse later.

But it’s not perfect.

For starters, it dries hard. You may think this is a good thing but during periods of hot and cold periods the rails of the track will expand and contract. Allowing them to flex can help prevent resultant problems — bent and buckled rails for example.

And as it dries hard, it can also carry vibration as the trains roll over the rails and create more noise. I’ve covered on this blog before, in this post on reducing noise levels. For many, this is the biggest problem with PVA and why many are dissatisfied with it.

Now admittedly, neither of these are massive challenges for many and for most of us they probably won’t be an issue but if you’re a perfectionist, are concerned about noise, and want the best adhesive for track laying there’s an alternative.

So what’s the best?

Liquid latex — rubber cement and available as Copydex — is now my preferred glue.

  • As easy to work with as PVA.
  • Easy to clean off track.
  • Dries transparent: no white marks as can happen with some brands of PVA.
  • Simple to lift track: no soaking, just warm up slightly and it should lift easily.
  • Sets with an elastic finish so allowing the track to flex when temperatures change.
  • Doesn’t carry sound as much — as shown in the article on reducing sound levels above.

The application is no more difficult than PVA. Just water it down — with a similar ratio to using PVA — and apply as you normally would.

Any problems?

Having considered the benefits of Copydex for track work, there are times where I won’t use it around track.

When fixing points and feeding droppers up through the baseboard for example. When drilling holes through the baseboard for the wires and point motor rods, its rubbery nature can cause it to wrap around the drill and peel off. Here I just use a dab of PVA.

And don’t use it for ballast cement. As Ian Morgan (of the Basingstoke Area Group of the 2mm Scale Association) found, Copydex dries with a stringy finish which means removing stray bits of ballast can end up pulling away far more than wanted.

I’ll also continue using PVA for a lot of my fun and experimental layouts and suggest it for beginners as most people usually have it lying around or can get it really cheap. (Copydex is cheap but not as cheap. You can get a 1ltr of PVA for under £10 while Copydex will cost around £15 for 500ml).


Extra Tip: For this article I recommend Copydex but there are other forms of liquid latex available and some of these can be obtained for much less than the branded solution. Although I haven’t done it myself, carpet fitters will apparently — if asked nicely — sell you liquid latex used for carpet laying in bulk quantities. If this works for you, please add a comment below to confirm this.

And, I’ll still use the good old white gloop elsewhere on my layouts — it’s great for scenery work.

In conclusion, there’s nothing really wrong with PVA for track laying but for a number of reasons it’s not the best. Copydex is a better adhesive, give it a go and let me know what you think.

  1. Thanks for getting back to me 🙂
    The layout is still under construction. Today I finished the underlay of the lower inner loop. No track yet. The incident happened during a test, where I glued some polystyrene to cork and track to the same cork and then left them overnight in a vise! I thing it was tight enough 🙂
    I know for sure that the PVA glue I used was old. it was sealed as new but I’ve had it for about 5 years now or more, never needed to use it. I have used it all up since then and am now using a new batch. Tomorrow I will do another test on a short bit of rail. Will keep you informed 🙂
    Be safe.

  2. I am about to start my layout. I have tested a short piece of N gauge track glued to a 3mm piece of cork which is also glued to some polystyrene. both with PVA glue. BUT, while the cork and polystyrene have bonded for life, I cannot say the same for the cork and track. After handling it for a few minutes, the track broke free. I used PVA is its raw format, thinking it is stronger like this. Maybe I am doing something wrong, I’m not sure but I really wish I can just use PVA glue!

    • Hi Joe, that’s odd. I’ve used PVA to glue cork and track down many times and not experienced this. Are you weighting the track down while the glue sets? Maybe it’s lifting slightly and not creating a strong enough bond. I use plastic bottles filled with water. Just rest them on the rails after gluing. Let me know how you get on. Thanks, Andy

  3. Just to confirm that “carpet layer’s liquid latex” is an excellent choice for fixing track. I’ve been using it successfully for 20+ years.
    Buy it in bulk from your local carpet shop & it will last forever.
