External flat roof/balcony refurbishment. All tiles have been lifted - cleaned and relaid with BAL fastflex - substrate fibreglass. Joints 10-15mm. Area 15m2. There was no expansion joint before...should i put one in? fill one of the joints with silicone?
Also instead of finishing round the edge with grout (large areas to fill) I thought about using sand/cement 6 to 1 with SBR for flexibility - sponge to finish what you reckon?
Thanks
