To fix a water-damaged worktop, you typically need to dry the affected area, sand down any swollen spots, clean the surface, and then refinish it with a matching stain or oil.
Water damage on worktops, especially those made from wood or laminate with a wood core, can cause unsightly swelling and discoloration. Fortunately, minor damage can often be repaired using a few key steps.
Here’s a breakdown of how to address water damage on your worktop, based on expert advice:
Steps to Repair a Water Damaged Worktop
Follow these steps carefully to restore your worktop's appearance:
-
Completely Dry the Affected Area
- Before you begin any repair work, it's crucial that the water-damaged section is completely dry. Use cloths or paper towels to absorb any surface moisture. You may need to allow ample time (potentially several days, depending on the severity and location of the damage) for the moisture within the worktop material to evaporate fully. Good ventilation can help speed up this process.
- Ensure there is no ongoing source of water leakage causing the damage. Fix the leak first if necessary.
-
Sand Down Any Raised or Swollen Water Spots
- Once the area is dry, you might notice parts of the worktop have swelled or become raised. Use a robust sander (such as an orbital sander) to carefully sand down these swollen areas until they are level with the surrounding surface.
- Start with a medium-grit sandpaper (e.g., 120-grit) to remove the bulk of the swelling, then move to a finer grit (e.g., 180 or 220-grit) for a smooth finish. Be cautious not to over-sand the unaffected areas.
-
Wipe the Surfaces Clean and Leave Them to Dry
- After sanding, the worktop surface will be covered in dust. Use a clean, dry cloth or a vacuum cleaner with a brush attachment to remove all sanding residue.
- For a thorough clean, you can wipe the area with a slightly damp cloth or a dedicated wood cleaner, if appropriate for your worktop material. Ensure the surface is completely dry again before moving to the next step.
-
Use a Strong Wood Stain or Oil That Matches the Original Colour of Your Worktops
- The sanding process will remove the original finish and colour. To restore the look and protect the wood, apply a wood stain or oil.
- Choose a product that matches the original colour as closely as possible. You may need to test it on an inconspicuous area first.
- Apply the stain or oil according to the manufacturer's instructions, often requiring multiple thin coats for the best result and durability. This step helps to seal the surface and protect it from future moisture ingress.

Practical Considerations
- Type of Worktop: These steps are primarily for wooden worktops. Laminate worktops with significant water damage where the laminate layers have separated may require more complex repair or replacement of the affected section.
- Severity: For severe swelling or structural damage, professional repair or replacement might be necessary.
- Safety: Always wear appropriate safety gear, such as dust masks and eye protection, when sanding. Ensure good ventilation.
By following these steps, you can often effectively repair localized water damage and extend the life of your worktop.
