Start to swell up from moisture and deform in structure/shape. The edges will start to swell up the most and with time will start to crumble and fall apart. Waterlogged Particle board can start to sag under the weight which can be extremely unsafe. , and more items.
When wet, particle board can sag under weight, which is unsafe. It will not take well to sharp objects such as high-heeled shoes or furniture that is being moved around. Wet particle board swells and expands with the moisture.
One source stated that if particle board and furniture made from particle board absorbs moisture and gets water damaged it can cause major problems such as: Start to swell up from moisture and deform in structure/shape. The edges will start to swell up the most and with time will start to crumble and fall apart. Waterlogged Particle board can start to sag under the weight which can be More.
In addition to being weaker, particleboard is also extremely vulnerable to water damage. If even a small part of particleboard is exposed to water, for example when a washing machine overflows onto a cabinet, great damage can occur due to the water “traveling”, via capillary action, inside the piece.
An answer is that particle board should never be used for outdoor applications, because it will not withstand the moisture from rain or snow for long. Once you see signs of particle board water damage, you will most likely have to replace it. Wet particle board provides a fertile ground for mold and mildew.
How do you fix a wet spot on particle board?
Dry the wet spot by using a hair dryer. Sand the water-damaged area with a medium-grit sandpaper by hand or by using an electric sander until the spot is flush with the dry areas. Vacuum or sweep up the sawdust created when sanding down the damaged particleboard.
Damp particle board will crumble and rot, so it is imperative to dry it out quickly, before problems occur. Sponge up any visible moisture on the surface of the particle board.
Can particleboard be repaired after getting wet?
Unless the water damage is significant, particleboard can be repaired after getting wet. Particleboard that will be exposed to moisture should be treated with paint or waterproofing material to prevent further damage.
What happens if chipboard gets wet?
When it gets wet, all chipboard–except for high density–soaks up water due to capillary action from the wood fibers. This causes the wood fibers to swell, and the board will appear bumpy and rough. Because the board is made of many small chips, there are many more open fiber ends to soak in water.
