Prolonged exposure or excessive concentrations of sodium hypochlorite can damage the wood fibres, potentially causing discolouration, weakening, or surface degradation.
Yes, high pressure from a pressure washer can damage decking and other timber structures. Excessive pressure can strip away the wood’s protective surface, splinter the fibres, and create gouges or uneven patches.
A gentle pre-wash and the use of a suitable chemical are crucial for cleaning decking and other timber structures to ensure effective cleaning without causing damage. The pre-wash helps to loosen dirt, debris, and surface contaminants, making the cleaning process less abrasive. Using an appropriate chemical, such as DeckClean Pro, ensures that stains, mould, algae, or grease are broken down effectively without harming the wood fibres.
Yes, biocides are essential in controlling unwanted organisms, such as algae, and mould, which can make wood appear green. These organisms thrive in damp conditions and can not only affect the aesthetic appeal of the wood but also compromise its integrity over time by retaining moisture and promoting decay.
WoodCareUK’s Expert Stain & Seal penetrating oil is more suitable for wood because it works by deeply penetrating the wood fibres, nourishing and protecting the timber from within. Unlike topical coatings that sit on the surface, forming a layer that can crack, peel, or wear away over time, penetrating oils provide long-lasting protection by enhancing the wood’s natural resilience against moisture, UV damage, and wear.
Yes, removing an existing failed coating can be a straightforward process if you use the correct product. DeckStrip Pro is our specialist paint or coating stripper and is designed to break down old finishes such as stains, varnishes, or paints, making them easier to remove without damaging the wood underneath.
Yes, wearing Personal Protective Equipment (PPE) is essential when using decking and timber restoration products to protect yourself from potential hazards such as chemical exposure, skin irritation, or inhalation of fumes. Common PPE includes gloves, safety goggles, a face mask or respirator, and protective clothing, depending on the specific product and application method. Details about the required PPE can typically be found on the product’s label or in the accompanying Safety Data Sheet (SDS).
The grey appearance of the decking after applying a biocide is likely due to the dead biofilm remaining on the surface after the biocide has killed it. This residue can dull the timber’s appearance, leaving a greyish layer that needs to be removed to restore the wood’s natural beauty. To prevent this from happening, it is advisable to give the surface a gentle clean before applying the biocide.
Identifying rot in decking or timber structures before cleaning is crucial to prevent further damage and ensure safety. Signs of rot can include: Softness or Sponginess: Gently press on the wood with a screwdriver or similar tool. Cracks or Splits: Advanced rot can cause the wood to crack or split, often along the grain.
