Blog, Central Chelmsford, Public Art, Public Realm Central Chelmsford – Large Platform Seat November 25, 2014 Christopher Tipping Leave a comment 25th November 2014 More images in today from Hardscape detailing the manufacture of the large platform seat for Central Chelmsford. Vinyl plotted with the design is applied to the granite slab before sandblasting. AS the process continues, the vinyl is stripped away to reveal areas to be sandblasted. The process is a skilled & precise one for Vlad to undertake. The slabs cannot be moved easily, so he has to move around the work. The sandblast is no more than 2mm deep across the slab. The fine honed finish on the surface will be retained under the vinyl which still covers the letters. The fine work is excellent. All the vinyl stencil which has been plotted and cut has to be weeded out by hand for sandblasting. The four granite slabs which make up the large platform seat awaiting more sandblasting outside. Granite slabs completed. When wet the granite will become almost uniformly dark. As the surface dries, the images and text will begin to reveal themselves. The areas with no sandblasting or shallow detail will dry out first.
