Thanks all for your thoughts.
You can use just one coat of zinsser if you like and only 1 topcoat but for outside work and for it to look good you would probably need two

The first coat of the zinser would be the primer, the second coat would provide a decent bonding surface for the top coat to adhere , or stick to

One coat of zinsser , one coat of top coat ? ......well it MIGHT look OK but you want it to last

That's what a decent tradesman would suggest and if I wasn't replacing the tiles and wanted a decent finish and not cut corners or try to do a cheap job that's the proper process
