Where Do Good Flooring Designs Come From?

Decorative Concrete

Gridding allows the contractor to transfer complicated art in smaller, simpler sections.
Transfer pouncing (above) makes it easy to transfer a design from a template to the concrete surface. With overhead projecting (below), the artwork is first transferred to a transparency, then projected on the ground to be traced.

Obtaining good designs or artwork is just half of the equation when considering using them on your floors. We commonly use three techniques to transfer artwork or images to the substrate on a regular basis: overhead projecting, gridding and transfer pouncing.

Overhead projecting

Overhead projecting is a simple but effective way of transferring your design to the floor. You will need to copy your image or artwork to transparency paper so that it can be used with the overhead projector. You may need to increase the size of the artwork to the largest scale onto the transparency paper so that it does not become distorted when you project the image. Remember, the larger or higher up you project from, the more resolution that can be lost. Once we have figured out our proper projection location and appropriate size, we simply turn out the lights and start to trace the image to the floor.

Gridding

Gridding is an ancient technique that many artisans use on a regular basis. This technique requires a series of grids to be drawn over your artwork. You will need to determine your own scale of grids to draw relative to the actual scale on the floor. An example would be as follows: Draw 1-in. grids (boxes) across the entire surface of your artwork. We usually label the vertical boxes with letters and the horizontal boxes with numbers, although it really does not matter. Using your predetermined scale, 1 in. might equal 1-ft. grids on the floor. Simply chalk a grid pattern at 1-ft. intervals. Using the paper grid, simply transfer the artwork from the designated grid onto the corresponding grid on the floor. For the initial grid transfer, the use of chalk is effective to draw the design because it is easily removed if you need to realign the design.

Transfer pouncing

Transfer pouncing is a great technique we use frequently that I am surprised is not more commonly used in the decorative field. This technique requires you to transfer your design to a template usually made of plastic or paper. We have had good results using our friend the overhead projector to once again project our image to plastic. After tracing the design to the plastic template, I like to lay the plastic on a sheet of plastic foam, which prepares us for the next step. Using a soldering iron with a fine tip, burn holes every inch or so through the plastic. By conducting this process over the foam, it enables the hot tip of the soldering iron to pass through the plastic into the foam leaving a clean hole in the plastic. It is difficult to achieve clean holes when trying to burn over something rigid like concrete or wood. Once all of the holes have been burned, take your template and position it on the floor. It is a good idea to put tape on all four corners of your template so that it does not move during the pouncing process. Take an old sock and fill it half way with orange chalk or baby powder and start to pounce the sock over your holes. Once complete, carefully remove the plastic stencil. If you drag the stencil during the removal it could smear the dots. We then connect the dots using a pencil or chalk.

As you can see, there are many sources of inspiration and techniques to use that can help you take your decorative concrete work over the top. Use each and every day as a learning experience and try some of these techniques. You may be surprised how easy yet effective they are.

Good luck!
