Wrong application of marble tile sealer?

[hendricks]

My builder has just finished sealing some tumbled marble tiles around my bath and shower.I was advised by the tile retailer to apply a coat of Fila Hydrorep to seal the tiles followed by a subsequent application of Filafob. My builder has forgotten to initially seal with the Hydrorep and has just applied the Filafob.

I am worried the tiles will not be sufficiently sealed. Should I ask him to strip the Filafob then start again?

Would appreciate any advice as I don't want to have a problem 6 months down the line,

The hydrorep is mainly for exterior and wet rooms.
I'd say just make sure you have at least 2 coats of the filafob.

Just ask him to put another coat of filafob on
