## Summary description

## Long description

Astra Masa papierowa 420 g is a dense paper-based modeling sheet by Astra intended for sheet crafting, model making and restoration. The 420 g weight provides a firm, stable surface that holds shape after cutting and shaping, while remaining receptive to common adhesives and paints. The material is suitable for producing structural elements, decorative reliefs, prototypes and hobby models where dimensional stability and surface workability are important.
Advantages
The high grammage delivers rigidity and minimal warping, enabling precise cuts and clean edges. Its paper composition accepts PVA and craft glues, acrylic and tempera paints, and can be sanded lightly to refine edges. The sheet format is easy to score and bend for folded constructions, and it can be layered or laminated to increase thickness and strength. Overall, the material balances workability with structural integrity for a wide range of manual and workshop applications.
Suitable for
Scale models and architectural mock-ups
Decorative reliefs and bas-relief elements
Prototype parts and small structural components
Restoration of interior decorative details and trim
School and hobby craft projects
Key specifications
Material: dense paper-based sheet
Weight: 420 g/m² (high grammage for rigidity)
Format: sheet suitable for cutting, scoring and layering
Surface: receptive to PVA and craft adhesives, acrylic and tempera paints
Workability: can be cut with craft knives, scored, bent, sanded lightly
How to use
Cut sheets to the required shape using a sharp craft knife and a straight edge for accurate lines. Score the material lightly before folding to ensure clean bends. When joining parts, use PVA or suitable craft glue applied evenly and clamp or press until set. For stronger assemblies, laminate multiple sheets with adhesive and allow full drying time before further processing. Prime the surface if necessary and apply acrylic or tempera paints; allow proper drying between coats. Sand edges gently with fine-grit sandpaper to smooth cut lines or refine details.
Usage recommendations
Store sheets flat in a dry environment to prevent moisture-related deformation. Test chosen adhesives and paints on a small offcut to confirm compatibility and drying behavior. Wear appropriate safety measures such as a cutting mat and a sharp blade for accurate cutting; ventilate the workspace when using solvent-based products.
