Glue Spread Calculator — Optimal Bond Strength
Work out the correct glue spread rate for optimal bond strength based on joint type and surface area.
Standard PVA spread for edge joints
Recommended for strongest bond
How We Calculate This
This calculator determines the correct amount of glue based on your joint area and the recommended spread rate for your joint type.
Spread rates
Edge joints: 175 g/m² | Face lamination: 150 g/m² | End grain: 250 g/m² | Veneer: 120 g/m².
The formula
Glue needed = Area (m²) x Number of pieces x Sides x Spread rate (g/m²)
