Cut STYROFOAM Brand Foam with serrated knife.

How do I cut STYROFOAM Brand Foam?

  • Cut with a serrated kitchen knife. Wax the knife blade with an old candle for easier, smoother cuts. Note: Never let children use sharp knives; we recommend a plastic knife for children.
  • Use an old electric knife to cut thicker pieces or several pieces stacked together.
  • Try dental floss for slicing through sheets – sounds crazy but it works! Stand the sheet on its side, hold one end of the floss at the bottom of the board, and pull the floss down through the foam.
  • Consider an electric or battery-powered cutting tool, such as the Styrocutter® or Styrocutter® Plus.

Can I paint it?  

  • Yes, paint STYROFOAM Brand Foam with an acrylic craft paint. Solvent-based paints may melt the foam.
  • Use a brush with stiff bristles for the best coverage.
  • Place small shapes in a zip-top plastic bag, add paint, seal the bag, and move the foam around until it’s completely covered. Remove from bag with a pick and let dry.
  • Use spray paint with caution; read the label carefully to determine whether or not it’s foam-safe. 
  • Hint: Insert a floral pick or wood skewer into your foam shape to use as a handle while painting. When done, insert the handle into a block of STYROFOAM Brand Foam while paint dries.
Glue STYROFOAM Brand Foam with low temp glue.

When gluing, insert wood picks between pieces of STYROFOAM Brand Foam to strengthen the bond.

Which glue works best?

  • Low-temperature glue guns set fast and hold tight.
  • Hot glue guns bond instantly but may melt the foam.
  • Thick, white craft glue is a tried and true favorite. Be sure it dries overnight.
  • For a snug bond between two pieces, gently rub them together before gluing.
  • Insert toothpicks or florist’s picks between pieces to hold them together while the glue dries.  This will also make the bond stronger.

    I have a tool that heats up and cuts the styrofoam with smooth edges. No little pieces making a mess like when I was using an xacto knife or knife with serrated edge. I bought it at Michael’s incase anyone is interested.

    When you glue picks between styrofoam, do you just break off the tip when dry?

    • Sharon says:

      Unless your pieces are very small, I don’t think there will be any tips showing. You insert half a toothpick into the first piece, and then insert the other half into the second piece of foam. Add some glue between the pieces, too. If you do have tips showing, I would clip them off once the glue dries. Good question! Sharon

    I am having trouble drilling hole completely straight through a 12 inch ball and/or a 12 inch cube. I have tried knitting needles, dowels and they never come through completely straight. Any hints on how to do this?

    • Sharon says:

      Hi Dorothy, I’m sorry you’re having trouble with this. 12″ is deep, so I can see why it would be more challenging. Have you tried using two knitting needles, and starting at the top and bottom? I’m thinking that the tools might meet in the middle. Please give this a try and let me know if it works for you. Thank you, and happy crafting. Sharon

    Hello, I Love the leaf wreath, and I don’t want to sound like a crabby old girl, but you know there are a lot of us smart crafters out here that can’t afford the fancy punches and cutters wit dies, so you should stop and think about us when you are punching, give a pattern of the leaf or whatever you are useing. I have the ability to draw one, but there may be some sweet ladys who can’t so when you are doing a beautful project, by punching out the design, or even cutting one with the expensive cutter, and dies that you have to have and leave something for us to print out. Thank you for reading this. Have a great day, Gerry

    • Sharon says:

      Dear Gerry, Thank you so much for reading Crafts ‘n Coffee, and for your suggestion. It’s a very good idea and I will see if our designer, Kathleen George, can provide a pattern for the leaf. I really appreciate the feedback! Sharon

    • Sharon says:

      Hi Gerry,

      I have the pattern now, and I will e-mail it to you. Have fun making the wreath, and be sure to share a photo on our Facebook page @StyroCrafts. Thank you. Sharon
