What Is Kitchen Cabinets Water Damage?

Hardwood, plywood, veneer, particleboard, and MDF are just a few of the wood-based materials used to make kitchen cabinets. Although these are long-lasting materials for kitchen cabinets, they aren’t water-resistant..

Water damage can be tough to avoid, especially if you don’t know it’s already happening until your cabinets have been soaking in water for several hours or days.

The damage could be caused by a leak in the kitchen faucet or under the kitchen sink, water getting in from the outside, or the occasional splash of water throughout the years.

These variables might lead to the spread of water damage throughout the kitchen. As a result, moisture can seep into the subfloor, flooring, and drywall, where it can swiftly spread to other parts of the house.

Cabinet delamination and warping, particularly in plywood or medium-density fiberboard kitchen cabinets, might be severe enough to necessitate a complete overhaul.

When plywood kitchen cabinets are damaged by water, the finish will peel off or the color may alter.

The staining on the cabinet is caused by water resting on it for too long, which will eventually fade the wood’s polish and cause discoloration. When water seeps into wood, it can cause the paint to peel off.

Particle board kitchen cabinets, on the other hand, are particularly vulnerable to water damage. The first giveaway for telling if your medium-density fiberboard (MDF) cabinets have water seeping into them for a while is if they are swollen in some places.

Your kitchen cabinets bubble up and lose their finish because the MDF boards have been wet with water and expanded. When water seeps into your cabinets, the laminate begins to peel away in large sections.

How Long Does It Take For Water Damage To Show

Having an adequate supply of water in the kitchen is a must, but if it leaks into the cabinets, it may be disastrous.

Overflowing sinks, dishwashers, broken refrigerator water lines, cooking steam, and frozen water pipes are the most common causes of water leaks. Damage from water can develop within three weeks.

When a high volume of water leaks through the kitchen cabinet, it is more likely to show up on the lower section of the cabinet, which is closer to the drain or water valves.

However, it might take up to five weeks before visible evidence of water damage can be detected if the leak is minor due to sustained long-term damage from a persistent leak or excessive humidity.

Step #3. Repair as necessary

If the damage is limited to your base, then a new one will suffice. Make a frame for it and place it on the cabinet’s floor first.

After that, take measurements of the old base and compare them to the new one. After that, attach the new floor to the cabinet’s frame. To make the floor waterproof, it is necessary to sand it down and coat it with sealant.

Sand the cabinet doors if they’re damaged. After that, use a shellac-based primer to prep the cabinet doors for painting. Paint it when it has been sanded down again.
