We know that you’re madly in love with your cat, but your hardwood floors are also in love. It’s just not a good combination.

The stench of cat urine is distinct, ammonia-like, and unpleasant, and it can pervade the entire house. Whenever you enter the house, the smell of cat urine will greet you.

The porousness of older, more frequently used wood floors exacerbates the problem, allowing urine to seep into the wood.

Cat urine smell removal from wood flooring is not an easy task, but it can be accomplished with the correct cleaning method and preventive measures that we will share with you here.

Pet Urine Penetrates The Deep Layer Of The Floor

Pet urine can damage hardwood floors over time, regardless of whether they are sealed or not. Pet pee can quickly sink into the subfloor, especially if it is urinated on a regular basis in a particular area of the floor.

Why Is It Difficult To Remove The Stain?

Ultimately, it is about the wood’s intrinsic qualities. Porous and hygroscopic, wood is a perfect building material. It’s like a sponge that absorbs liquids quickly if you don’t wipe them off right after the spill.

Usually, this is plywood or some compressed wood. Because of this, the wood will absorb urine if your cat has an established practice of peeing in the same place repeatedly.

You’ve probably come to this page because the subfloor has been breached even though you have carpet, carpet pad, laminate, or tile on top to assist “catch” some of the irritating liquid.

Prevention For Future Stains

Sometimes, your cat’s behavior is beyond your control, as you’ve discovered the hard way.
They may do it all over again.

You can, however, maintain some degree of control over your hardwood floor by refinishing or sealing it.

Is Sealing Really Useful?

Sealing your hardwood floors is a great technique to keep urine from ruining your floors. Choosing a floor sealant or other pre-finishing products for your floor is critical.

Increasing the plywood layer that covers the subfloor is your primary goal. You can consider it as securing your pet’s paws to the hardwood floor with sellotape.

Hardwood flooring, in contrast to tile, is permeable. Even the tiniest amount of moisture can penetrate deep into the wood’s structure.

The damage to the wood fibers is difficult to notice since it is time-consuming. As the moisture seeps into the wood, molds and mildew can grow.

Scratches increase the level of moisture absorption in hardwood flooring from pets’ claws. Urine can seep into the subfloor if the floor seals are scratched.

Even if the outside surface is strong enough to keep liquids out, the small gaps created by nominal scratches can still let in harmful moisture.

Hardwood flooring’ protective finishes and coatings are impermeable by design. They may not be able to avoid scratches, but at least they won’t spread to the wood.

It’s better to apply multiple coats of pet-resistant hardwood flooring rather than just one. Your hardwood floor will be better protected if you use a thick sealer.

Cleaning patterns after a pet has peed on your floor are important when applying a sealant. You should sand the floor before applying multiple coats of floor sealer if the hardwood surface is rough.

Catalyzed cross-linkers can also be used to protect your floor.

Final Verdict

In order to avoid punishing your pet further for making your subfloor stained, you need to find an effective solution. Removing cat urine odor is easier by cleaning up any spills right once to keep them from soaking deeper into the wood.
