Cork tiles are a natural, eco-friendly option that add warm, rustic charm to your home. Whether you’re using cork tiles on your floors or walls, they offer excellent insulation properties, sound absorption, and durability. To maintain their appearance and longevity, it’s essential to seal them properly. In this guide, we’ll explore the benefits of sealing cork tiles, why it’s necessary, and how you can seal them for a long-lasting finish.
Do Cork Tiles Need Sealing?
Yes, cork tiles do need sealing. Cork is resilient but porous, allowing dirt, moisture, and stains to penetrate easily. Without sealing, cork tiles can absorb spills and water, which could lead to swelling, discolouration, or even mould growth.
There are a few situations where you might want to reconsider sealing cork. If you're using cork tiles in a low-traffic area or on walls, the need for sealing might not be as urgent. However, in high-traffic areas or places prone to spills (such as kitchens or bathrooms), sealing is essential for long-term protection.

How to Seal Cork Floor Tiles?
Sealing cork floor tiles requires a little patience, but the results are worth it. Follow these steps for a clean, even finish:
1. Clean the Tiles Thoroughly
Before you begin sealing, it’s crucial to clean the cork tiles thoroughly. First, sweep or vacuum the area to remove any loose dirt and debris. Afterward, mop the floor with a mild detergent and water. Be sure to avoid excess moisture as cork is sensitive to water. Allow the tiles to dry completely before applying the sealer.
2. Choose the Right Sealer
Selecting the right sealer for your cork tiles is essential. There are two main types of sealers: wax-based and polyurethane-based. Polyurethane sealers are the most popular choice for cork floors because they provide a hard, durable finish that resists scratches and moisture. Look for a water-based polyurethane sealer, as it’s easier to apply, dries faster, and has less odour compared to oil-based options.
Wax-based sealers are another option, providing a softer, more natural finish. However, they may require more maintenance and are less resistant to stains and moisture than polyurethane sealers.
3. Apply the Sealer
Once you've selected the right sealer, pour it into a clean container. Then, use a high-quality paintbrush or foam roller to apply an even coat to the cork tiles. Work in small sections to ensure the sealer doesn’t dry before it’s spread out evenly. Be sure to apply the sealer in thin layers to avoid puddles or streaks.
4. Allow the Sealer to Dry
After applying the first coat, allow the sealer to dry completely. Drying times can vary depending on the product used, but it usually takes between 1-2 hours for water-based polyurethane to dry. Check the manufacturer’s instructions to ensure you allow sufficient time for the sealer to cure before walking on the tiles.
5. Apply Additional Coats
For the best protection, it’s recommended to apply at least two or three coats of sealer. Make sure each coat is completely dry before applying the next one. The more coats you apply, the more durable and long-lasting the finish will be.
6. Cure the Tiles
After the final coat of sealer has dried, allow the tiles to cure for at least 24-48 hours. During this time, avoid placing furniture or walking on the floor to allow the sealer to fully set.
How to Seal Cork Wall Tiles?
Sealing cork wall tiles is a similar process, but it doesn’t require as many layers of protection as floor tiles. Here’s how to do it:
-
Clean the Wall Tiles – Dust and wipe down the cork wall tiles using a soft cloth and mild cleaner. Avoid soaking the tiles as excess moisture can damage cork.
-
Apply the Sealer – Use a paintbrush or roller to apply a thin coat of sealer to the cork tiles. Work in small sections, ensuring that the sealer is spread evenly across the surface.
-
Allow to Dry – Wait for the sealer to dry completely before applying a second coat if necessary. As with floor tiles, ensure the surface is thoroughly dry before proceeding.
Waterproofing Cork Tiles
Waterproofing cork tiles is an important consideration, especially in areas like bathrooms or kitchens where exposure to moisture is common. While sealing cork tiles will protect them from light moisture, a specific waterproofing treatment may be required for areas exposed to heavy water use.
A polyurethane sealer can help to waterproof cork tiles, providing a durable barrier against water damage. However, some cork flooring products come pre-sealed or treated with a water-resistant coating, which could reduce the need for extra waterproofing. If you’re unsure whether your cork tiles require additional waterproofing, consult the manufacturer’s guidelines for the best approach.
How to Protect Cork Tiles?
In addition to sealing, there are several ways you can protect your cork tiles from damage:
-
Use Area Rugs – Place rugs in high-traffic areas and ensure they have non-slip backing to reduce wear and surface damage.
-
Clean Spills Immediately – If you spill any liquids on cork tiles, clean them up as soon as possible to prevent the tiles from absorbing the moisture. Use a soft cloth to blot the liquid, avoiding rubbing it into the surface.
-
Avoid High Heels and Sharp Objects – Cork is a relatively soft material, so sharp objects or high heels can leave marks or dents. Try to avoid walking on cork tiles with high heels, and place furniture pads on the legs of your furniture to prevent scratches.
-
Regular Maintenance – Regularly sweep or vacuum cork tiles to remove dirt and grit, which can wear down the finish over time. Occasional mopping with a mild, pH-neutral cleaner will help keep the tiles looking fresh without damaging the sealer.

Frequently Asked Questions
Do cork tiles need to be sealed?
Yep, cork tiles do need sealing. While cork is naturally durable, it’s also porous, so sealing helps protect it from spills, stains, and moisture. This is especially important in areas like kitchens and bathrooms or any high-traffic zones.
What’s the best sealer for cork tiles?
Polyurethane-based sealers are the go-to for cork floors. They’re tough, scratch-resistant, and help protect against moisture. For a quicker, less smelly job, a water-based polyurethane sealer is a solid choice as it dries fast and is easy to apply.
How long does it take for sealed cork tiles to dry?
For water-based polyurethane sealers, the first coat usually dries in about 1-2 hours. Make sure to let each coat dry fully before walking on the tiles. Always check the manufacturer’s instructions to get the drying times spot on.
Can cork tiles be waterproofed?
Yes, cork tiles can be waterproofed with a polyurethane sealer, which gives them an extra layer of protection from water damage. Some cork products come pre-sealed or water-resistant, so it’s worth checking the manufacturer’s info to see if extra waterproofing is needed.
