how to cut the the best from our film faced plywood?
storage:
always clean and repair the formwork panels before storage, the formwork should then be stacked off the ground on level supports and under cover. framed formwork panels should be stacked alternately face and bac to back to avoid face damage by bolts etc. if panels are wet, do not allow them to dry too rapidly.
sealing of edges:
phenolic film faced plywood edges are fully sealed by the factory and it is the most important that all edges remain sealed. to obtain full value from a phenolic film faced plywood sheet any recut edges should sealed as soon as possible with water proof paint sealing of holes.
any hole made in film faced formwork panels should also be sealed to prevent water entering. if water does enter it may cause swelling around the holes.
cleaning and repair:
to obtain full life, cleaning should be carried out immediately after each use. phenolic film faced plywood may be wiped with release agent or cleaned with water and stiffbrush. it may be necessary to use a hard wood scraper but care should be taken not to damage the plywood face. do no use a wire brush or sharp metal scraper to dislodge hardened concrete.
