Plywood itself isn't really good in water, because it can absorb it. To help make plywood waterproof, you can treat it with a sealant. Sealant is applied just like a paint.

How is premium plywood different from cheap plywood?

Premium plywood is much more different than cheap plywood. The materials involved in making cheap plywood are boards sawn and hewn from trees. Whereas, premium plywood is laminated through the multiple thin layers of wood to form ply sheets. The size of AA grade plywood is generally β€˜4 X 8’ The cheap plywood is often referred to as solid wood to make it different from all the other manufactured wood products. Solid wood is made from logs that are slaughtered from trees, limited in size, and can be made in whichever size a buyer wants. Premium Plywood is dimensionally more stable than that solid wood. The irregular weather conditions and temperature can cause harm to the cheap plywood, and especially in Sydney where the weather remains hot and humid. The cheaper plywood of Sydney might ruin after a few months. On the other hand, premium plywood is resistant against inappropriate weather conditions and maintains its shine and design for a long time. Plywood is typically cross-banded. The layers are alternatively perpendicular to each other that results in reduced expansion and contraction. The plywood is classified in different categories, and it also varies upon the geographical location. The categories include commercial grade plywood, waterproof BWR grade plywood, BWP grade marine plywood and flexible plywood. There is a possibility that plywood served in Sydney won’t match the quality of Plywood Tasmania. The difference depends on the grade and material used in making, also on its thickness and manufacturing brand. A composite board is made by gluing layers of hardwood and also softwood veneer. While the premium plywoods are thicker in layer and structure, and more often used as hardwood, which is stronger and heavier than softwood, and favours a lot of purposes that are to be satisfied through the wood. How to identify whether the plywood is of cheap quality or premium quality? Determine the area of plywood, whether it is moisture-resistant or water-resistant and good for humid areas. Check for the ISI mark. It should be ISI 303 which is a normal one, while an ISI 710 is marine, waterproof and a premium one. The plywood should have a wood face and recon face veneer. If you buy heavy plywood it should be denser. The sides of plywood should reveal core layers as straight lines, without gaps and overlapping. Also, it should reveal wood core and nail-holding ability. If the plywood of 18mm bends or breaks then its quality is poor.


What is the difference between bwp and bwr plywood?

bwp = boiling water proof bwr = boiling water resistant THERE IS NO DIFFERENCE !!!!!!!!!! Source: http://blog.positiveindians.in/plywood/bwp-vs-bwr-grade-plywood.html The acronym BWP stands for 'Boiling Water Proof', While BWR grade means 'Boiling Water Resistant' plywood. The general naming convention used in the industry is that BWR grading is used for marking plywood, while its counterpart BWP grade is used in the case of Blockboards. Technically speaking there is not much difference between these two terms. The quality tests on BWR grade plywood sheets, as well as BWP grade blockboards are quite similar. The glue used in the construction of both these types is synthetic plastic resin (phenol formaldehyde) which is considered better than Urea formaldehyde resins used in commercial MR grade (Moisture resistant) plywood sheets. If a board is marked with BWR it means that it is a waterproof exterior grade plywood, and if it is marked BWP then it should ideally mean that it is an exterior grade waterproof block board. Both BWP and BWR grades are widely used in the construction of furniture that is likely to get some exposure to water. Hence it is a preferred choice of material for making kitchen cabinets and other kitchen furniture. For quick difference between plywood and block board: Plywood -is thin sheets of veneer stuck together Blockboard - is blocks of solid softwood covered by sheets of veneer on both sides Or you can get it in detail at : http://blog.positiveindians.in/plywood/plywood-vs-blockboard.html
