Extending Chimney Breast - Plastering Question...
I have a small chimney breast in my new house - more a flue than chimney. It
is only 1 brick deep from the back wall, but unfortunatly its not in the middle. As i am putting an LCD on it i want to make it look central to the room. I am planning to extend it to one side by around 250mm using stud work/plasterboards/plaster. The question is do you build it such that on the outfacing wall the stud work is flush with the current plaster or (as i think you would) do you build it such that its ~3mm back from the current plaster line such that when its plastered its much easer to jet a seamless join? A pic of what I am looking to do is at http://www.convery.me.uk/temp/ChimneyBreast.jpg (Red = addition) |

I would build it flush and skim the whole front including the existing area. If the existing area had been much bigger and not in need of reskimming, then I might consider building it recessed and only skimming the plasterboard. -- Andrew Gabriel |

Once sanded flat you can get a supprisingly good finish. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

But be warned that it's not ideal having a stud partition abutting a brick structure like the chimney breast; you'll probably find that over time it will crack along the junction due to different movement/thermal properties of the different materials. Might be an idea to dryline the whole of the front of the chimney breast (ie clad it all in plasterboard and skim the whole thing, not just the studwork) - I don't know how you plan to fit the TV, but this might be advantageous for other reasons, eg concealing the connecting cables behind the plasterboard.

A pic of what I am looking to do is at http://www.convery.me.uk/temp/ChimneyBreast.jpg (Red = addition) I'd hack off the existing plaster, screw a single length of vertical studding to the wall the same depth as the brick where you want the new end to be and just glue/nail a sheet of plasterboard over the lot. If you try and build right up to the existing brickwork with wood and plaster over the join it'll eventually crack if you use the fire. The plasterboard should stop this happening and there's no need for studwork to fill the small gap (maybe 200mm) between the bricks and the new end. You can then plaster the two opposing faces of the brick and wood on each side to blend in with the plasterboard. It might be an idea to have the plasterboard overlapping the brick/wood ends by a few mm so you can apply plaster into the resulting gap and have a couple of nice straight edges to work to. -- Dave Baker - Puma Race Engines (www.pumaracing.co.uk) |
