But, in spite of all this, a question that often comes up with regard to plywood is that of water resistance. Can plywood be waterproof? Can plywood be effectively used to create furniture pieces for areas that experience higher water inflows. These questions are genuine, because as we all know, plywood is made of wood veneer, and when the wood is exposed to water for long periods, there can be damage and warping.

But for plywood to be used efficiently in interior spaces like bathrooms, kitchens, patio, etc.waterproofing is essential. There is no other way out, especially in environments where there is excessive moisture. A waterproof ply board is a need of the hour.

And we at CenturyPly are constantly innovating products to make them more efficient and customer friendly in nature. One outcome of which is the waterproof plywood.

MR Grade Plywood

The MR in this plywood refers to “moisture resistant”. This means that the MR grade plywood is well-suited to interior use such as the bedroom, living room or the study room. Here, you should keep in mind that MR grade is not a waterproof ply board. It is treated with resins such as formaldehyde to resist humidity and moisture, and cannot withstand high inflow of water.

To explain more, it is suited for home and office furniture and other uses such as shelves. If there are areas that are likely to get wet very often, such as kitchen shelves, this would not be suitable in the long run.

BWR Grade Plywood

The BWR here refers to “boiling water-resistant”. This is used for both interiors and exteriors, being treated with phenolic resins to make it water resistant.

Unlike MR grade, BWR grade plywood is good for use in areas that have prolonged exposure to water, for example, in kitchens and bathrooms. It is also suited for locations with a lot of humidity or rainfall. The BWR grade plywood will last longer and the furniture piece made from this plywood would remain as good-looking as the day they were first made. Note: BWR grade is a water resistant and not a waterproof ply board. It can sustain water for longer times, and is best suited for interior uses.

What makes these plywood so versatile? It’s the quality of the veneers used, combined with undiluted resins, which give it these excellent properties. Some quality checks, to maintain the standard and get verified certifications, for this type of plywood involve submerging a sample in boiling water for three days and then testing the plywood on the basis of strength and other properties.
