2 textures on one object

Hi!
Is it possible to have for 1 object have 2 different textures on one UV…

So the situation is like… i have a building … so first tiled texture is for building material and second texture is for details like dust,paints,bullet holes etc… is it good idea or better use other solution?

Im not sure if one object could have 2 textures, but if your detail texture has transparency you could put a plane as close as posible to the objects side you wantt to texture with the detailed texture, an other way i could thik of is puting one texture over the other with an image editor
