There is no particular preparation for the interior of the floating object, unless it has contained salt water in which case it must be rinsed.
Instructions of use
Mix the product well before application.
TOPFLEX is poured into the interior through the inflating valve thus creating an internal elastic membrane that closes porous areas and seals minor leaks. After introducing the product, the object must be moved in all directions in order to spread the liquid over the totality of the surface to be treated. It is essential that the boat remains inflated while the TOPFLEX dries (3-4 days). Then slightly deflate it, (about 30 %), introduce some talc and move the object in all directions as before, then inflate again so that the airflow finishes spreading the talc.
