Practically any surface modeled can be weathered with a dry brush technique . Before weathering the card kits it is recomended to pray with Testers dull Cote as this will give the card a protective coating that can then be weathered. Weathering is best carried out with that old tired worn out brush that's been lying at the bottom of your paint box.

Take your brush, which should be a flat faced brush, and rub it into the colour you have mixed up, which should have been mixed up with a very little thinners or water. Gently rub the brush onto a piece of cardboard, removing all but a small amount of paint. Almost immediately gently rub the almost dry brush over the desired area in a soft circular scrubbing motion. This should leave the required faint trace of weathering colour on the wall. For wood affect, the brush should follow the grain of the wood.

These techniques can be used anywhere that requires ageing or distressing. Weathering powders are readily available, but I prefer to grind up my own using artists chalk rubbed over sandpaper. To ensure the powders stay where put, spray the area with thinned down acrylic matt varnish, Remember to highlight any areas that would attract water, like leaking drainpipes, rising damp etc. The acrylic varnish will seal all the powders thus ensuring that the powders do not detach themselves.
