Here are some of the best ways to protect hardwood floor from water damage:
• Apply a water-resistant finish.
The most important step is to apply a water-resistant topcoat such as polyurethane or varnish to the floor. These seals penetrate the wood and help protect hardwood floor from water absorption. Re-finishing your floors every few years will help maintain protection.
• Use floor mats.
Place protective mats near entrances to your home, especially in especially rainy or snowy weather. Mats will absorb moisture and dirt from shoes before it gets tracked onto the floor.
• In high-moisture areas, apply a damp-resistant builder’s wax or oil.
In kitchens, bathrooms, mudrooms, etc. apply a coat of wax or wood oil. These provide protection while still allowing the wood to breathe. Reapply periodically.
• Consider a waterproofing additive.
Add waterproofing seals or water repellents to paints and stains before application. These add-in water protections can provide enhanced water resistance. Some also react to water exposure to form a barrier.
• Install vapor barrier and drainage layer.
For basements or other below-grade floors, install a vapor barrier on the ground below the floor and drainage materials like gravel or a drain mat. This prevents moisture from seeping up into the flooring.
• Control indoor humidity levels.
Use an air humidifier or dehumidifier to maintain indoor humidity between 40-50% relative humidity. Extreme dryness or dampness can cause wood floors to expand, contract, warp or even buckle. Proper humidity is key.
• Protect edges and seams.
Apply sealant or weatherstripping tape to edges, seams and expansion joints in the floor. This prevents water from seeping in at seams or edges.
• Place protection under high-moisture furniture.
Use protective pads under high-moisture furniture like pet bowls, plants, grills, etc. This prevents leaking or spills from seeping into the wood flooring.
• For large spills, wipe up immediately.
Apply a water-resistant cleaning agent to any large spills on wood floors immediately. Do not let water pool or soak into the wood. Absorb with cloths or mops and wipe clean.
