Hi.any dugestions pls.we had loft converted 4yrs ago.outside walls are half stone and render would say render.it was not smooth render though.i do know what it is called.its the kind they put in a small machine and wind it so it throughs it on first coat.at the time of convertion i decided to have old one removed and have new pebble dashed.its only 4years and pebbles has started falling.front and rear is not bad but side is exposed to wind and rain.few large chunks have fallen.i can see the first coat is not scrached at all.i am intrested to have conservatory built on rear side but pebbles are falling all the time whenits windy.i am thing have it done again.should i go for render or pebble dashing.if i go for render then what advise can u give ie,how thick it should be,time between first and second coat etc.thanks
