To know how to use the foam board sheet,we need to know what is foam board.
 

Foam board is a strong and lightweight material,usually consists of three layers, an inner layer of polystyrene or polyurethane foam that is clad with an outer facing on each side of either a white clay coated paper, cotton archival paper or common brown Kraft paper.


 

According to the usage,the thicknesses from 1mm to 10mm are commonly available.And 3mm,5mm.10mm is the most popular thickness.
 

Foam sheet can be with or without adhesvie in different different colors,but the black,white and fluorecent is the most commons.
 

Actually foam board is easily cut with a sharp craft knife or picture framing mat cutter.But when pepole use the foam board,one problem often encounter when cutting foam board is what we like to call the “snow-plough effect”. When your knife is blunt or used at the wrong angle you can cause the internal foam layer of the board to bunch up causing an unsightly edge and making it increasingly difficult to cut.
 

The sharp part of any trimming knife is the flat surface rather than the tip so smooth cutting is achieved when you present more of that surface to the board. Have a shallow angle rather than a steep one.

 

If you want to cut tight curves use a pointy scalpel or a tool specifically designed to cut foamboards.
 

Foam board is commonly used for the mounting of prints, advertisement,photographs,handicraft, and as backing in picture frames,etc.
 

Here we just take the foam board usage in picture framing for reference.For picture framing use we recommend the acid-free alpha cellulose clad boards as they have a longer lifespan and do not leach acids into the artworks. In high end conservation framing a further barrier of cotton rag boards or alpha-cellulose boards should be placed between the foam board and the original artwork.
