I worked with a friend years ago, he needed to fill in some deep holes, so he said I'll mix up some merlin, this was a combination of basecoat plaster and cement...............It was great, went off in about 15 mins and rock hard. Is it something all you pro's use or does it have drawbacks?
magic merlin?

When working as a jobbing bricklayer in the past I have put a handfull of board finish into the mortar mix to harden it up really quick when needed.
According to the boffins at BRE this mixture can induce a sulphate attack in the mortar joints in damp conditions. It should take a couple of years to come out, so there is enough time for the cheque to clear.
