What to expect from Marine Plywood
Marine plywood is purpose built structural plywood with a permanent Type A bond glue, and come under the standard of AS 2272 or BS 1088. It is intended for use in marine or high moisture environments. Each face veneer should be a minimum of 1.0mm and not thicker than 3.8mm, each core veneer shall be no thicker than 4.8mm.
Marine plywood is made from selected species and therefore has known and consistent structural properties. AS2272 assigned stress grade is F14 and is manufactured with 2A grade veneer faces, these must present a solid surface that is free from open defects and free of knots other than pin knots, which will readily provide a surface that will accommodate a clear or painted finish.
All timber products may be subject to decay and termite attack under certain conditions, which is why all plywood must be treated with 3 coats of epoxy on every surface for a waterproof finish.
Defective bonds, pleats, overlaps, and gaps in faces should not be present. Occasional gaps may be repaired using veneer inserts bonded with the proper adhesive. Further information is available on our website ask us for the article from AABB titled “Plywood Idiosyncrasies”
NOTE: ALWAYS PURCHASE 2 X 3 MM MDF SHEETS WHEN HAVING PLYWOOD SHIPPED TO PROTECT THE FACES DURING TRANSPORT
Hoop pine Timber
Hoop pine ply is made from Australian plantation grown hoop pine. It is by far the best plywood manufactured in Australia today. The veneers are of an even thickness and the marine plywood is made to AS 2272 which is a more stringent standard than BS 1088 but like all good things you pay a premium for it. The B-B hoop exterior plywood is manufactured to AS 2271 and is superior to many of the imported marine plywoods to BS 108
