Bonding small acrylic letters to exterior wall render
Looking for a second opinion on this. I have been asked to produce letters from 3mm coloured acrylic, approx 40mm high, and fixed to an exterior wall (in porch area, very little rain)
My concern is about the fixing method, I consider tape out of the question as it won’t be suitable for a slightly uneven surface, and will be difficult to apply to the back of the letters in production. The other option is a Tec 7 silicone, but run the risk of the silicone pushing out the sides during install. Is there another suitable “cement” style material I can use to achieve this?
I want to push them to just apply everything to a panel but they are not keen. I feel this is the only route though…
Any thoughts welcome
