Tried some uni a while back. It was full of white lumps some hard some soft a bit like wet entrinet think that's how you spell it, almost every trowel full had it in it. Managed to sort it in the end but took twice as long . Thought the sell buy date had been changed but b& q swears they didn't do it. Contacted bg had two decent replys , gave the bag I had left to their rep for testing then nothing. I wasn't looking for compo just an explaination. Anybody know if this normal or a one off. End of the day don't think I'll buy it again.
