Hi, I've just removed an old conservatory from the back of the house and where it joined the house, it has left long lines of brown mastic. I've tried using mastic eater, but that hasn'et really helped apart from making a mess. Any ideas how to remove it?

dont use brick acid as it only reacts with cement based products(its basically 18% hydrochloric acid and neutralises the cement in mortar concrete etc). so if you dont want to effect the surrounding mortar joints or the slabs/concrete/ block paving below then elbow grease is the answer!

i am afraid noseall is right elbow grease is the answer but if the mastic is oil based then white spirit and a wire brush may help
