How the magic of the Riva varnish is achieved


From the number of layers applied, to the methods used yesterday and today, everything has been said about the veneer of the varnished mahogany Rivas. The splendour of a Riva finish has an eternal


fascination. Here’s a quick summary of the process involved in achieving it – one that can take several weeks to achieve perfection. At RAM, a hull undergoes a total of 20 passages in the varnish workshop and receives 19 coats of a clear two-component polyurethane coating generally made by Stoppani or Veneziani. After applying the mahogany tint on the raw wood, the


first step in the varnish process is to apply six layers with a brush, one coat a day after sanding down. This process builds up the thickness of the varnish.


Next, a series of three layers are applied at two-hourly


intervals, using a spray gun, and are then sanded down after three to four days of rest. The operation is repeated three times, resulting in a total of nine layers. Then, a very fine sanding down is carried out before spraying two layers, a process known as final simulation passage, with an interval of between one and one and a half hours between each, before another sanding down. The process continues with the application of two


coats of anti-UV protection, with identical intervals to the preceding applications. The final touch is obtained with a very soft, fine polish that creates the characteristic deep velvety shine of a Riva.
