What is the best way to apply self adhesive deck patches to a boat?
A Add some soft soap, the type than comes in handy dispensers for the washroom, to a little water. Add enough soap to the water to enable a film of water to remain without pulling back when it is applied to the deck flanges. Coat all the areas where the deck patch will stick and also the surrounding areas. Peel off the backing material and add the patch to the wetted area. The soapy water will allow you to move the patch around and stretch it out until it is where you want it. Drying time in the height of summer is less than an hour. Indoors in winter it may take several hours. We use one of our screw top pots to keep the solution in so there is always some handy in the workshop.
