Here is a good indication of how good ACF50 is. These are the ends of my mini scaffold tower I cleaned them up well over 2 years ago and on one stem I smeared ACF50 and I left the others. Can you spot the one that had the ACF50 They are stored in a dry area and so are not subject to rain washing off any ACF50 but the area does get damp.
Hey! Surely that is not a wall at 'Sharp Manor' not exactly period is it, iron rubbed in mortar joints is modern, it became popular in the sixties,.
I was expecting lime mortar with pencil joints, big stone arches with massive key stone bricks, tiled Kneelers at the bases of all the gables.
Sharpie have you been bullshitting us as to your heritage.
Oh! The AFC50 has done a great job of protecting the tower.
