Plywood is moisture resistant

Why do you need moisture-resistant plywood?

The ability to repel moisture is one of the important properties that expands the scope of plywood sheets. Moisture-resistant plywood is a durable material that can be processed, lacquered, stained, painted, laminated, and veneered. The sheets are easily processed on machines, sanded, cut, drilled, fastened, and combined with different materials. This makes plywood the most popular construction material.

Thanks to its waterproof qualities, moisture-resistant plywood is widely used in frame construction, concrete work, roofing, flooring, and furniture production. Such a strong, wear-resistant material is indispensable in construction and major house or apartment repairs.

You can buy moisture-resistant plywood in Ukraine on the Win-Wood website. The catalog features samples of certified products from manufacturers. Delivery is available to any city in Ukraine.

Moisture-resistant plywood: production and types

The production of moisture-resistant birch and coniferous plywood follows the same technology. Thin layers of wood, processed on a peeling machine, are glued together. Plywood acquires water-repellent properties through the use of various types of low-soluble synthetic resins during production. These not only provide moisture protection but also increase resistance to chemical exposure.

Treating the material with varnishes, paints, and modern chemical impregnations enhances the water-repellent properties of plywood. Impregnation with bakelite varnish significantly increases the water-repellent properties of plywood. However, calling moisture-resistant plywood “bakelite” is not entirely correct, as there are other types of plywood with water-repellent characteristics.

Which moisture-resistant plywood is better to buy?

The building materials market offers moisture-resistant plywood of various grades. Three main types can be distinguished, differing in properties and characteristics. It is better to know the features of each type to use the material correctly for its intended purpose.

• FC – medium moisture resistance, glued with urea resin. The material does not withstand prolonged contact with water, as the inner veneer layers are not treated. The outer layers do not absorb moisture, so the product is positioned as moisture-resistant plywood. Sheets can be purchased in thicknesses from 3 to 30 cm. This plywood can be used for all types of finishing and rough work indoors, for partition construction, and for making furniture and other carpentry products.

Advantages of FC moisture-resistant plywood:

– eco-friendly
– suitable for indoor use
– natural wood texture
– suitable for making furniture
– easy to treat with additional substances
– can be combined with different materials

Disadvantages of FC moisture-resistant plywood:

– may deform with prolonged water contact

• FSF – glued with phenolic resin. Mainly made from birch veneer (beech and pine are less commonly used). This plywood has enhanced moisture resistance. It is used only for exterior work due to the non-ecological composition of the glue – phenol is hazardous to health. The material is resistant to weather and temperature changes, and unaffected by precipitation, so it is widely used in automotive and shipbuilding. If you need to buy waterproof plywood for outdoor construction work, this type is the best choice. Pine plywood differs from birch by being lighter in weight. Laminated FSF can be used indoors.

Advantages of FSF moisture-resistant plywood:

– does not deform under moisture exposure
– suitable for outdoor use
– withstands mechanical loads
– not prone to defects

Disadvantages of FSF moisture-resistant plywood:

– non-ecological, not suitable for indoor use

• FB – so-called moisture-resistant bakelite plywood – a material impregnated with alcohol-soluble resin (BS) or bakelite varnish (FO). Various grades of bakelized plywood can be found on the market. Their main difference lies in the application of alcohol-soluble or water-soluble phenol-formaldehyde resin to the inner or outer veneer layers. Since bakelite plywood can withstand prolonged water contact, it is widely used for yacht siding and in aircraft construction.

Advantages of FB:

– high density (comparable to expanded clay concrete)
– withstands temperatures from -50 °C to +50 °C
– not prone to corrosion during prolonged water contact, as well as in acidic and alkaline environments
– high wear resistance (up to 15 years)
– suitable for both internal (finishing, cladding) and external (formwork, roof finishing) construction work

Disadvantages of FB:

– expensive moisture-resistant plywood. The price of FB is higher than other types.
