Dear Donny

QWhen I recently went to replace a broken tile in my bathroom, I discovered it was on top of another tile. Taking the old tile off would be problematic, so what do I use to fix the new tile back on the old tile? William Devine, by email

A

As it’s only one tile, I would use Bal Floor Tile Adhesive – something like Bal Flex One or a rapid set. Q

Can you recommend a cleaning product for stubborn rust marks on the floor of the health centre where I work, made by the feet of medical beds? Ray Bown, by email A

Bar Keepers Friend is simple to use – just mix the powder with a little water to make a paste. Apply over the rust, leave to dry, then wipe with a dry cloth.

Q

The colour of our composite garden fencing has faded – what should I use to restore it? Mrs Norma Shipley, by email

A

I’d apply a Zinsser primer, such as Bulls Eye 1-2-3 plus, until the existing colour of the fence can no longer be seen. Then use a quality exterior paint for the topcoat which will last a decade – I suggest something like Zinsser Allcoat. Blackfriar also manufacture quality paints/primers.
