Looking to waterproof a 6.84 square metre external balcony on a customer's house. The walkway of the balcony is OSB sheeting which has previously been painted with a waterproofing paint. However it appears this was only one coat and has failed in a number of places. Can you please advise what you feel the best product would be to make good the waterproofing on this OSB board? Once completed composite decking will be laid back down for the customer to walk on. Hope you can help advise on this. Regards Carl
