Tips on Cutting Foam Boards

Although foam boards are quite convenient to use and lightweight too, cutting them with precision isn’t easy. Therefore, it is important to learn the right way and use the appropriate tools to cut foam boards. Following simple techniques can help you overcome or even avoid potential issues while cutting foam boards according to the shape you desire for your project.
Cutting a Straight Line

One of the basic things you need to start with while working with foamboards is to cut a straight line. If you can do that, creating panels won’t be as difficult for you. The panels canthen be glued together to make blocks (or boxes). These can be further used to build a terrain piece or anything else you can imagine.

To cut a neat straight line, first draw a line while holding a metal ruler firmly on the foam board. While you do that, you need to be careful regarding how the thickness of your blade relates to the thickness of the pencil you have used. Ideally, you must cut exactly through the drawn line, and not on one side or the other of it.

Start cutting by holding the blade vertically at the top of the line and pierce the top layer of the foamboard. While moving along the marking, avoid cutting all the way through in one go. Slowly pull the blade down along the line, angling the blade as you go so as to increase the cutting surface.
How to cut foamboard

While doing so, you need not apply too much pressure as the first cut will run through the top layer smoothly all by itself. You will then repeat this cut in order to score the bottom layer. During the entire process, it is important to keep your ruler still lest the alignment falls apart. Always use the specific tools and cutters meant for cutting foam boards and strictly avoid scissors for the purpose.

Common Cutting Mistakes
There are three common mistakes that people make while cutting through foam boards. 

1. Applying too much pressure
Applying undue pressure while cutting will not only make the blades of your cutter blunt but will also result in creased or folded cutting edges. This technique spoils projects demanding finer art work and causes untidiness. The best way to avoid this is to figure out in advance that you would require multiple cuts to get through the board rather than simply exerting pressure while cutting. 

2. Using a dull blade 

If you use a blade that is not sharp, you are likely to tear off the foam center. A dull blade will easily ruin your work no matter how careful you try to be.

To avoid this, always keep spare blades handy while working and replace your blade once you start to see the warning signs. 

3. Cutting at an angle

This is a common problem that most people face while cutting through foam boards. While making cuts at an angle is easy, it usually results in a piece having slanting edges. The only solution for this is to pay due attention to the angle you are holding the blade at. It is possible to fix beveled edges, but certainly not as easy as avoiding them from happening in the first place.
