Drawing moisture out of cement

DerbyBorn · 2016-08-09T18:45:36+00:00

My son-in-law has bought a "build it yourself" "stone" firesurround, The instructions are not very clear. For setting the hearth on a bed of mortar it is a bit ambiguous as to whether wetting the stone is a good or a bad thing - it refers to one or the other drawing the moisture out of the mortar without it being clear as toy wheter this is a good or bad thing. What would you suggest?

Yup. Te difference between an 'engineering' brick and a cheap'n'nasty soft brick that 'looks traditional' is immense.
