It is not easy for everyone to cut Styrofoam until you know the right steps and use appropriate tools. To break the Styrofoam material easily, you need to follow the steps given below. Otherwise, it can lead to uneven edges. Things you will need before cutting the Styrofoam are butter knives, credit cards, candle, serrated knife, electric knife, power saw, hot wire cutter, dust mask, safety goggles, and cutting board. Here are the steps to cut Styrofoam.
Create a breaking line
First, you need to create a breaking line using a thin and sharp object. You must penetrate the Styrofoam to make a straight cutting line. Make a groove in the foam using even pressure. You can do this using a credit card or a butter knife or key. In fact, you can use any sharp and thin object.
Now, break the foam along the cutting line. Situate the Styrofoam on the countertop or the table for the effective outcome. The scored line along the surface of the edge on the countertop is the best way to break the Styrofoam.
Next, you need to gently press down along the cutting line to make a clean break. Remove the excess Styrofoam with a craft knife if necessary to create a clean break.
Cut the Styrofoam
Use a waxed kitchen knife for cutting the foam. Wax your serrated kitchen knife. You can do this easily using a candle and running the blade of the knife over time a few times. We suggest using a white candle so that there is no colored candle wax on the Styrofoam.
Next, cut the foam with the knife using sawing long motions. Don’t do this fast, otherwise, you will make an incorrect cut. You must do this steadily and at the same time, apply pressure on the knife while moving the knife to decrease the chances of crushing or breaking the foam.
How to cut Styrofoam with an electric knife?
You can cut the Styrofoam with an electric knife. Make sure you choose a quality product such as a fish fillet or carving knife. This will help you create clean and precise cuts in the foam.
Place the electric knife on the Styrofoam along the cutting line that you have made already. Don’t put too much pressure on the knife. However, you must force it a bit so that the serrated blades can cut through the foam gently.
How to cut Styrofoam using a craft knife?
You can use a craft knife to cut this type of foam easily. A craft knife is great for cutting thin and small pieces of foam. However, if you have foam thickness above 1 inch, we don’t recommend using this tool.
Compared to the serrated blade, which can tear the foam, the craft knife has much sharper blades that compress or flatten the foam. If used skillfully, you can avoid uneven and malformed cuts in the think pieces of Styrofoam.
To have precise cuts, again, we recommend using a craft knife. This cutting tool is good for creating v-cuts and bevel-type cuts in the Styrofoam. Cut through the foam using slow movements and create a shallow mark in the Styrofoam.
Once you make the initial cut, you can run the craft knife easily through the foam. Make sure you do this several times to create deeper cuts. Continue this until you have completely cut through the foam from top to bottom.
While cutting the foam, it is important to change the blades in the knife. For example, if you have dull blades, it will lead to uneven and rough slices in the Styrofoam. This way, you can’t achieve the desired cut.
How to cut Styrofoam using a hand saw?
Another tool you can use to cut Styrofoam is the hand saw. Coping saws, hacksaws, and compass saws can create straight cuts in the foam. Don’t use a saw that has a flexible blade. It is because the flexible blade can wobble in the Styrofoam and result in uneven cuts.
You can cut the foam using a hand saw with long and sawing motions. Make sure you put enough pressure on the saw to increase the probability of accurate cuts. Don’t put too much pressure. Again, balance is key to avoid crushing the foam.
How to cut Styrofoam using power saws?
Power saws such as band saws, jigsaws, and scroll saws are good for cutting wood. At the same time, these tools have been found useful in cutting through Styrofoam. Any of the power saws can create clean and effective cuttings. You can use any of these tools for large and bulky pieces of Styrofoam.
Since there are many types of power saws, you need to follow the instructions for the one you want to use to cut the foam. When using this type of saw to cut the foam, you need to wear safety goggles. Otherwise, the residual sparks can damage your eyes.
How to cut Styrofoam with a hot wire?
You can also use a hot wire cutter to cut through the Styrofoam. If you have don’t have this type of tool at home, you can quickly buy it from your local craft store. This is an essential item when it comes to home improvement projects.
Hotwire cutters can melt through the Styrofoam. The heated wire is useful for creating smooth edges. So, you can use this type of cutter to create your desired shapes and designs of the foam.
To use the hot wire cutter, you need to apply pressure on the tool along the cutting line. The pressure must be consistent. Don’t apply too much pressure and proceed with caution. Otherwise, it can cause burns.
