are you saying there is a trough to fill where a fire place once stood. if so how deep is the trough?

 

[andrea4g]

its about 10mm deep where the hearth was

 

[noseall]

its about 10mm deep

10mm...ouch! very little tolerance.

You can't go far wrong with Marley bitumen paint and primer, available from homebase. I have used it and have worked a treat. The only trouble is that it doesn't stop condensation. I have tanked an external wall with it and it has stopped the damp, but when I felt the wall today, it was soaking wet due to condesation. It's good stuff though, easy to apply, had no problems to tell the truth.
