Hi
strip it the same way as a normal vinly = Stripper- Green or Black pad- Thorough rinse with wet pick up - more clean water and mopping some would say use a little acid neutraliser , frankly little white vinegar will do just to neutralise the alkalinity of the stripper although a few self neutralise - reapply couple coats depending on wear and desired finish , allow 24 hrs before buffing to desired finish high gloss use ultra high speed to finish, if not a standard high speed machine will do. but not slow speed ie, 155 or 175 they are to slow really.
as long as it is not strartica
you can seal it with eternum
