Asked earlier today by Yorkie (York Paul) to demonstrate how I go about replicating mortar on my buildings like this below, I produced this short video. This is an inexpensive method that anyone can do, regardless of skill set. Unlike washes that require time and patience, this is easily applied and desired results easily achieved. All you need is white chalk, scalpel, tray and some clear coat, ie Dull Cote or similar. Now if you were after a different coloured mortar, the use of pastel chalks could be utilised. Enjoy the video tutorial... Cheers, Gary.
