Water Damage and Timber

How to minimise water damage to your timber articles whether you are a manufacturer or homeowner

Water damage is a problem often encountered in kitchens, bathrooms and other high moisture areas. The problem affects all solid timber and veneers especially Beechwood. Generally speaking, water damage appears as either a discoloured white panel due to delamination of the coating, or black in colour indicating growth of mould or fungi underneath the timber coating.

How manufacturers prevent discolouration

Manufacturers can prevent discolouration of timber by being aware of the causes and taking precautionary steps to minimise its occurrence in this field:

  1. Before coating the timber ensure it is dry, this minimises the presence of moulds and fungi.
  2. Ensure the coating system used has low moisture transmission. This prevents the timber article being exposed to moisture from being hydrated to a level which would support the growth of moulds and fungi. MIROTHANE PU Polyurethane coatings have low moisture transmission.
  3. Ensure sharp edges of the timber articles are removed and apply the coating generously over edges or profiles. Liquid coatings flow away from sharp edges leaving only a thin film. Multiple coats on sharp edges are required to obtain maximum protection.
  4. Avoid the use of single pack lacquers in areas of high moisture especially over Beech or Steamed Beech, solid timber or veneer. The minimum system requirement recommended by Mirotone is a two pack system such as MIROTHANE PU Polyurethane coating system.

Preventative action Information for the Home Owner

The best guarantee for a long life of any coated timber article is the familiar acronym TLC (Tender Loving Care). Take the following precautionary steps to keep water damage at bay:

  1. Avoid high humidity build up by ensuring the room the wooden article is kept in is properly ventilated, open windows or turn on air extractor fans in kitchens and bathrooms.
  2. Wipe up any spills as they occur and try not to miss the spots at the bottom of doors or any other area water may pool. These are the most common points of coating failure.
  3. Avoid damage to the protective coating through physical impact e.g. damage caused by mop handles and vacuum cleaners.
  4. Avoid the use of abrasive materials and cleansers as this will dramatically shorten the life of the protective coating.
  5. The regular use of a wax-based, silicone free, non-abrasive polish can be beneficial in reducing the transmission of moisture through the film. A silicone free polish such as Mirotone’s SPRAYGLOW furniture polish is recommend.
