usually get spec changed ,but architect fell out with builder so nothings being changed now , wanted someone i could trust to work with us on job, so we dont lose out on future work, so dont want to bring in big firms, thing is now with parex products and sps you can buy off shelf where anyone can doe it sto are slowly losing out ,when architects realise sto applicators and products are no different than any others and they can save a fortune , theyll stop specing it,
oh and parex dont have "trainers"
