This will be the office and workshop for the Ice House Diorama I have been working on. The time period is around 1925. I have a set of the Bragdon Chauks which I want to use. Suggestions are gratefully accepted. [;)]
It is hard to say without seeing the structure. Typically brick buildings are stained beneath the window sills. You’ll also have stains where smoke exhausts. Of course, with any brick building you’ll have to provide the mortar. There are two ways to do this. 1) paint the building grey and drybru***he red color over the grey mortar. 2) Paint the building your brick color and wash a diluted grey over the brick wiping off with a paper towel or cloth.
The same grey wash works great for wood and roofs.
Near the groud you will have splashes the same color as the dirt in your area especailly on the weather side of the building.
Mostly drive around and look at the buildings in your area. Find ones the same age as your building (not necessarily the same era) and look at how it has weathered.
Mouse pretty much nailed it. Check photo online or whatever of similar structures. If possible print the photos and use them as a guide while you weather.
Remember those Bragdon Powders are extremely potent. Use them sparingly.
Weathering made EASY !!! from someone who weathers RR and military models. Artists chaulk and water-based paints mix together !! to make a great dull, weathered look, not enough… scrape the chaulk with an X acto blade to make powder and let the powder mix with paint while it is still wet. This technique works on all types of kits and looks great on 1/35 scale military models as well, if you are into that end of the modeling spectrum.
Artists chaulks can be substitutued for with billiard chaulk as a good alternative and the type you mentioned are most likely a good choice. A note about the paints, I have a topic on the forum about paints and you will note I advocate craft paints and why ? They are an inexpensive alternative to matched paints, but that is up to you what you choose, also, you can dry acrylic paints with a hair dryer set on low heat and this will actually " set " the paints.
Hope these ideas help…
