Supply and fix thick x wide Primo SD non-directional static dissipative vinyl sheeting, manufactured in accordance with EN 649 and laid over an earthed grid of aluminium tape in FloorworX acrylic conductive adhesive which has been spread using a trowel fitted with an A2 notched blade at a rate of between and per litre on a previously prepared Class 1 sub-floor in accordance with SANS 10070, using FloorworX Self Leveller when required, including all cutting and waste. The sheeting must be rolled in both directions with an articulated 68kg three-sectional roller immediately after it has been laid into the adhesive. Joins must be butted, grooved and heat welded using the manufacturer’s welding rod, ensuring that the welding rod bonds to more than 70% of the sheet thickness. After completing the installation the floor must be electrically tested for resistivity in accordance with the requirements of SANS 6160.
Lee experienced hardship during the tough years of the Japanese occupation from 1942 to 1945. During the war, Lee learnt Japanese and first worked as a SAS (Singapore Administration Service) officer in Sentosa islands where he listened to Allied radio stations and wrote down what they were reporting in the Hodobu office (報道部 – a Japanese propaganda department).  Towards the end of the war, by listening to Allied radio stations, he realised the Japanese were losing the war, and fearing that a brutal war would break out in Singapore as the Japanese made their last stand, he made plans to purchase and move to a farm on the Cameron Highlands with his family. However, a liftboy in his office told him his file had been taken out by the security department, and he realised he was being followed by Japanese security personnel (which continued for three months), so he abandoned those plans as he knew if he went ahead, he would be in trouble. Lee set up private small enterprises during the war to survive; among which was one that manufactured stationery glue, branded as "Stikfas".
