Title: 1.5mm cork sheets
Post by: jonclox on February 12, 2014, 08:33:16 pm
I must say that I was disappointed with the results of my usage of this.
I laid it over a plain board with what I thought was ample glue under it. In use its lifted, stretched and torn. In fact at the moment the baseboard looks a mess.
As I really only intended to use it under track for sound deadening I`m just ripping the rest up and making do without it.
In time it would have all been covered with scenery, buildings etc so the loss isnt devastating but its still a shame.
Next time (??) it will be 3mm cork or nothing for me.
We live and learn by our mistakes  :-\

Which glue did you use, and did you cover all the cork or just some squiggles of glue, and was the board surface varnished?

I just corked under the track, covered the entire underneath surface with PVA, and stuck it to unvarnished bare MDF. No problems.

Yes I have used the same cork on my layout under the track. I have glued it down with copydex and then glued the track to that in the scenic areas with no problems.I have used it on my fiddle yard but have pinned the track, it makes it easy to make any alterations if needed.

Admitted the glue was PVA `squiggled' on over treated plywood. Obviously far to sparingly but that's in the past now and I only want to look forward .
Ive only posted this thread as a warning to others and to see peoples reactions

The warning about attempting to secure large areas of cork with only squiggles of PVA onto treated board with little to key onto is worth sharing now you have expanded on what happened. Sorry you have had this happen to you.

The use of cork just under the rails and glued over its whole surface is really quite useful so, if you haven't gone too far now, having a second go with a more secure method might pay dividends.

The cork is being removed where its not under track but what remains is being firmly glued down before the track is finally glued down .
I might investigate using balsa sheeting another time. I use it now but only in small areas---- and it does get well glued down.
