Preparation tips:
Untreated weathered grey decking: To ensure maximum oil penetration, first treat and restore the timbers natural colour with Ronseal Decking Restorer. Use Ronseal End Grain Protector to protect the vulnerable end grain on untreated decking.

Previously finished decking: Remove dirt, dust, grease and oil with Ronseal Decking Cleaner and Reviver, any patchy existing surface coatings should be removed with Ronseal Decking Stripper.

New timber decking: After leaving for up to 6 months to weather, clean the decking with Ronseal Decking Cleaner which opens the pores of the wood allowing for maximum penetration of the oil.
