Design studio Transparent House has a neat new way of dressing up stark industrial bare concrete floors. Supposedly their floral patterns can be applied to both newly poured floor and that where the concrete is already set.
No details on their website, so I'm guessing it's some sort of a sandblasting or acid-etching technique. http://www.transparenthouse.com/main/#/en/2/7/104/354/ [Flash, click on Portfolio, then Industrial Design if you don't see it at first] - via RuebenMiller
paints, sealers and simple repairs can create a
touch of beauty and add years to the life of your home's concrete surfaces.
From driveways to patios to basement floors,
and even landscape stones and edging, you can do simple projects to
customize the look and add protection from weather and harsh chemicals.
In most cases you don't
need to hire a professional to achieve this.
