Making an outdoor stoned arch effect structure

Recommended Posts

Hi, wondered if anyone would be kind enough to help me with this one...I am designing a structure for an open air venue that would have arches atop columns. The arched area would need to look like it is made of stones. It will need to withstand the elements. I am thinking a wooden frame (3 by 3), skimmed with ply and then with a paint effect on top. For the stone affect maybe exterior polyfilla to allow me to scrape into it to get a stone and grouting effect, then paint. Finally perhaps a sealant of some sort. I haven't designed a structure for open air before. Does anyone know if this sounds faesible? Thank you!! :biggrin:

hi - where are you based? an idea for the stone effect, try peter evans studios they do sheets of plastic vacformed shapes - bricks, stones, leaves, windows etc. ive used them before and although expensive its good stuff, easy to cut to shape and fairly easy to paint. coulds be worth a look.

I would start looking at windloadings first before worrying about the finish.

Unless you are qualified to calculate the required strength for your set, get an engineer to look at it. You may even find that the venue has someone who does that for them.

You may find that you are better off making these arches out of a frame with a painted gauze rather than a solid material.

Hi I agree with Roderick. The wind is a powerful element. With a gauze there is something for the wind to pass through, as opposed to creating a sail. The product to use, would also be dependant on the time the structure is to be standing etc and a standard gauze could not be any good. There are manmade gauzes available to buy.

Probably not much point in posting on this topic.

The OP hasn't been back to the forum after posting her question......

Why do people do that?

 

 

Hi Thanks for the message. Am new to this site, so just finding my way around. :D
