Instructions
Add a few drops of water at a time to hardened brick compound to soften it. Mix it with a wooden craft stick, or a spoon. Continue to add a few drops of water until it reaches the consistency of a thick paste.
Cover the mixed brick compound when you're not using it. If it dries out, it can be moistened again at any point.
Use a wet rag to remove hardened brick compound from a dollhouse if you find you have made a mistake. Soak a rag in water and wipe the rag against the side of the house, then scrape the compound off with a butter knife or similar object. Use several rags until all the brick compound has been removed.
