I'd like a recommendation on the best/easiest way including products to enable me to remove existing decking stain from my decking to allow me to re-stain. Do I use a high power pressure washer and blast it off (though I'm not sure this would be the correct action!), or is there a product that I can use that will be quick and efficient and not take me absolutely ages (the decking size is approximately 50sqm)?????
It depends on type of stain that was originally used, and just power washing will probably not remove all the original stain. You need to soften up the original stain first with a propriety decking cleaner, Cuprinol, Ronseal etc, or a product called PrepDeck. Apply this to the stain, wait for about 20 mins then try to power wash off at low pressure.
Hope this helps.
