Kitchen Waterproofing is Important?

Imagine you invest all of your life savings to turn your dream of having a dream house into reality and just within a couple of days, it begins getting water damaged? Sounds like a nightmare, isn’t it? Sadly, many people out there are actually living this nightmare just because they have shown minor negligence during the construction phase by not waterproofing the house.

These are the people who think that waterproofing a house is nothing but a waste of time since the environmental humidity and moisture can’t be strong enough to affect the solid building material. However, their misconceptions get cleared in a few weeks, as soon as mould and mildew begin to invade their property secretly, weakening the foundation and all the essential facets of the house, including flooring, cabinets, cupboards, etc.

The worst thing is the homeowner suspects the presence of these secret invaders when they’ve done with their goal of deteriorating the entire property, leaving the homeowners with heftier maintenance. Thus, the only solution to prevent this calamity from occurring is to waterproof your home. However, waterproofing the entire house can add too much to the overall construction budget which not everyone can afford.

In this situation, the best thing you can do to minimize the odds of water damage is to waterproof only those parts of the house that are more prone to getting deteriorated by moisture; the areas that constantly stay in contact with water and moisture like the bathroom and kitchen. Some of you might be thinking to compress down the end cost even further by deleting the name of the kitchen from the list of areas to be waterproofed. Don’t think of doing so since it will end you up with severe consequences. What are those consequences and other important things to know about kitchen waterproofing, let’s have a look!

Why is waterproofing your kitchen important?

Unlike other parts of your home, the factor behind water damaging your kitchen is not only the humidity but there is a huge list of deteriorating factors including a failed garbage disposal system, leaky pipes, blocked drains, spills, and overflowing sinks, steam vapour, and faulty or old plumbing. Sadly, almost every person has to face one of these problems at least once in his life and if you don’t know, only a single occurrence will be enough to ruin your dream kitchen.

Once the water is spilt onto the floor, either due to drain blockage or leaking pipe, it will flow towards the wall through the gaps present between your kitchen tiles. This water, when come in contact with floor and wall cabinets, would affect its timber and turn them into a perfect habitat for mould and mildew. Even if the water damage is not so severe, the wood will become warped, discolored, and brittle. Thus, waterproofing your kitchen is important to protect your massive investment.

Which areas of your kitchen should be waterproofed?

The answer is simple; all those areas that get a massive water activity. Some of these areas are mentioned below

Around and under the sink

Your sink is the main point through which water enters the kitchen so it’s the most important part that needs to be waterproofed first of all. Otherwise, whenever an unusual thing would happen, like blocking off drain holes or cracking of pipes, the water would escape to the cabinets present around and under the sink.

To waterproof these areas, you first need to check for leakage or cracks. On finding any water stain or sign of moisture, you have to fill the crack immediately with a filler like chalk or sealant. Also, you’d need to ensure that your sink has not gotten loosened. If so, tighten it or replace it as soon as possible otherwise, the water will seep through the gaps, into your cabinets.


Although the kitchen countertops usually possess tiles onto their surface so water can’t seep through them to reach the cabinets. Still, when water comes into contact with your countertops, either in the form of backsplashes or spills, it starts accumulating under the countertops to make your kitchen environment unhygienic.

Not only this water accumulation stimulates the growth of germs but it also emits an absurd odour into the kitchen. Thus, to prevent it from happening, you should better fill in the cracks present in linoleum and wood with paint and polyurethane. The paint will cover the cracks whereas the polyurethane will prevent the leakages.


It doesn’t matter how good you’ve maintained your kitchen cabinets, water will make an entryway to get inside them – especially in the cabinets present around the sink. So the first thing is, there’s no way to prevent water from seeping into the cabins. And since water can’t be removed out of cabinets completely, once entered, it will initiate mould growth and wood rotting.

Thus, the only method to protect your luxury kitchen cabinets from the eyesore consequences of water damage is to waterproof them. And for this purpose, you can go with polyurethane, especially the oil-based one.


Last but not least, your wooden kitchen floors are also an important part that needs to be waterproofed. Otherwise, the water will seep through the gaps and cracks of your wooden planks which in turn, will discolouration, soften, and in the worst situation, rot the wood. To waterproof a wooden kitchen floor, usually, two techniques are used; first, to use only the waterproof wood all across the area or refinish the typical wooden floor with polyurethane or any other vinyl product.

What is the Best Material to Waterproof your Kitchen?

The answer varies based on the area of your kitchen you are thinking of waterproofing. For example, if you are up to making your kitchen cabinets water-resistant, you can go with the spray-on rubber coating. Such spray-on waterproofing coatings are widely available in the market but you should go with the product that is heat resistant, durable and dries out quickly.

Similarly, to waterproof your kitchen floor, you can use peel and stick tiles that are not only highly affordable, and easy to use but are also available in a vast variety of designs so you can choose the one according to your kitchen layout and theme.
