Ay up lads I've had some monocouche done recently by some one who I know I've had the front of my house done and a strip about a foot wide and 8 feet tall down the side of my house by the guttering and in stead of taking the down pipe off he left it on which made it awkward for him and he hasn't filled the bead out which looks quite a mess can he just monocouche straight over the top again or will it all have to be knocked off
