Hey, just wondering if the foam you get of a builders site would be fine to use, its the same as styrofoam except its light green ?
also there are so many opinions on what to use. is it best to use grout for a few coats first then pondtite ? if some one can give me a simple explanation that would be great cheers tallis.
