chimney stack removal
 
I am considering removing my chimney stack right through the house. How should I prepare the bare brick walls for plastering after removal? I have heard of instances where soot from the chimney has reacted with the newly put on plaster and made the plaster "bubble up" after it has cured. Is there any special treatment to combat this? Any help greatly appreciated.

How will the appliances be vented?

hi, no venting needed,we have adequate central heating in the house.

How is the heating system vented or exhausted?
How is the water heater vented?

heating system/hot water is controlled by a gas combi-boiler in the kitchen which is in turn vented through the wall. This boiler then feeds radiators throughout the house.

Is this a brick house or wood structure?

You may want to clean the brick with TSP or other cleaner prior to plaster. It may be in your best interest to seal the brick before the plaster is applied.

If you fur out the area and then install the plaster then that should lessen the condition.
