Frequently Asked Questions
Find answers to common questions about this product
1000 micron (1 mm) greyboard is slightly lighter and easier to cut, making it ideal for school projects, lightweight backing, or craft applications. 1500 micron (1.5 mm) greyboard is heavier and stiffer, best for model making, mounting artwork, or when extra durability is required.
Yes — all our greyboard is produced from 100% recycled fibres, making it an eco-friendly choice without compromising strength or performance.
Absolutely. Greyboard works well with most PVA and spray adhesives. You can paint directly onto it with acrylics, poster paints, or gouache. For printing, it’s better as a backing board rather than a printable surface.
Use a sharp craft knife with a metal ruler and make several light passes rather than trying to cut through in one go. This ensures straight, clean edges and avoids tearing.
The right size depends on your project:
A5: Small projects, postcards, book covers
A4: School displays, craft sheets, signage backings
A3: Artwork mounting, model bases
A2: Large displays, structural craft, portfolios
SRA1: Oversized sheets (640 × 900 mm) for trimming down or large-scale work
Yes. Greyboard is a safe, non-toxic material widely used in schools and craft classrooms. We recommend adult supervision for cutting, as sharp craft knives are required for clean edges.
