ACM adhesive for studs, advice needed please?
I have an issue that some ACM panels that we fitted at a school last week have all fallen off. We used this product Novaweld Signfix 33 to fix the studs to the rear and then chemfixed to the wall. This product claims to be suitable for use on ACM. The ACM has now fallen off and the studs are still in the wall with no adhesive on them at all, they look brand new. The ACM is only 3mm thick and 700 x 600 in size so not even heavy. The adhesive was applied as per the instructions and left over the weekend to cure. What product do you guys use?
I need to get something for tommorow as the school opens on Monday!!
