Decked areas to be treated must be clean, dry and free from traces of dust, dirt, oil, grease, wax and silicone.
New Decking Preparation
For all bare wood decking including tanalised, pressure treated and preservative impregnated decking timbers.
New softwood decking
- Treat the decking with Ronseal Total Wood Preservative for best protection
- If possible, preserve all sides including end grain prior to installation
- Sweep the decking with a stiff broom to remove all traces of surface dirt and debris
- Use a suitable decking cleaner if required, before oiling
New hardwood decking
Hardwood decking usually requires a period of weathering to allow the surface grain to open up. This allows for better adhesion of the decking stain. Check the decking manufacturer's guidance on how long decking should be left to weather before treating.
Old Decking Preparation
Old 'coating' type finishes such as decking paints, varnishes and varnish type stains must be fully removed back to bare wood before oiling. Depending on the condition and type of finish, it may require more than one attempt to fully remove the old coating.
- Ensure that all 'coating' type finishes have been fully removed to expose bare wood by either jet washing or using Ronseal Decking Stripper
- To clean and restore decking that has turned grey or silver over time, treat with Ronseal Decking Restorer or Ronseal Decking Cleaner and Reviver
- Then treat as 'New Decking' above
Please Note: Ronseal Quick Drying Decking Stain is not compatible with garden decking that has been previously oiled as the oil in the timber will prevent the decking stain from bonding. Previously oiled decking boards should be allowed to weather for at least a year and scrubbed with methylated spirit before attempting to apply this product.
