Hi, Scholes,
Well, you can call me, JR here from Soundscape HiFi, Singapore
Anyway, most of us have concrete walls, and most of us use 3M Command Adhesive double-sided tapes, which does not destroy the paint, even those on cornices:
http://www.3m.com/us/home_leisure/command/products/mountingstrips.jhtml3M also has Velcro pieces, interlocking fasteners, and info can be found at:
http://www.3m.com/us/home_leisure/command/products/interlocking.jhtmlHowever, in our weather, some lose effectiveness in about 6 months or longer (not on the wall, but on the 8th nerve), and you have to change the tapes again. For the Corners - you'll need 3 on each edge, Echoes - 4 on each edge, Seams - 8 since it is longer and heavier. You can email me your email id at
[email protected] and I'll send you a rough drawing (handwritten for the moment).
There are even stronger tapes from 3M, double-sided foam tapes (not the black removable ones), or outdoor weather tapes. All can be found at the local DIY shops in the malls - like at Tampines Mall, Bugis Junction DIY shop on the 3rd floor of Seiyu, Takashimaya DIY shop, etc.. or call 3M Singapore - 6 454-8611 . Just note that these are not easily removable from walls, and may pull out the paint when you attempt to remove them.
Now if you want it more permanent to last for years, yet removable, you could find out the spots where you intend to place the 8th Nerve items. Then find some thin and very small wooden pieces - maybe visit a wooden toy shop, or a carpenter's shop, etc. Put small pieces of 3M Command Adhesive tapes on these wooden pieces, and stick them to the wall. Then use thumbtacks with short points to secure the 8th Nerve. Or push pins, we have a lot of 8th Nerve Push Pins at our showroom (free). We didn't include them in the package since they can't be used on solid concrete.
We'll try to have some of these wooden pieces at the showroom next weekend.
