Quick Answers

Phenolic plywood vs bakelite-coated plywood: what's the difference?
They're the same product under two names. "Bakelite-coated" is the historic Italian commercial term, derived from Bakelite (the first industrial phenolic resin). "Phenolic" is the current technical term.
What thickness of phenolic plywood for vertical formwork?
18 mm is standard for residential walls and column forms. 21 mm for fair-face architectural walls or wide-span forms. Below 15 mm, rigidity is insufficient against fresh-concrete pressure.
How many reuse cycles can be expected?
Depends on the panel: up to 10 cycles for Form Basic (EN 636-2 melamine), up to 15 for Form Extra, up to 20 for Pro Form (EN 636-3 phenolic), and up to 25 for the HDO range. These are maximums under average site conditions with proper release agent and protected storage.
What's the price per m2 of phenolic plywood?
2026 reference: 28-38 EUR/m2 for standard EN 636-3 18 mm panel, 38-52 EUR/m2 for HDO high-density. The most useful number is cost per pour (price / cycles), which levels around 1.65-1.80 EUR/m2 across classes.
EN 636-2 or EN 636-3: which to choose?
EN 636-2 for residential sites with low rotation, sheltered formwork between pours, interior building. EN 636-3 for infrastructure works, formwork exposed for more than a few weeks, fair-face concrete, and any public-tender spec requiring permanent moisture exposure.
How to store phenolic plywood on site?
On dry pallets, off the ground. Under waterproof tarpaulin against rain. Panels stacked horizontally with edges protected. Never stood against a wall — permanent deformation in hours. Never in direct contact with fresh mortar or concrete.
