I've just put up a wall in the back garden, and had a professional builder finish it off with a sand/cement render, as I would never be able to get the finish right.
Only it seems very soft. If I rub my finger along a squared off edge, the edge rubs off leaving a rounded one, and you can easily pick the edge off with your finger nail without any effort. Already (6 weeks after it was done) there are a number of nicks along the edge caused by careless passers by and spoiling the finish. I've also noted that if you rub your hand over the surface of the wall, it feels very sandy and grainy.
Is this normal, or has the builder got the mix wrong with too much sand or something?
Thanks for any advice.
Matt.
