Hi newbie here looking for advice.
I had a new pvc conservatory erected on an existing single brick dwarf wall. One large wall between my garden and the neighbours is double thickness. The company who erected it suggested I paint the wall internally with a bitumen type paint to damp proof it then dot n dab insulated plasterboard. I painted 3 coats as directed on the tin and once dry I dot n dabbed the insulation board along with hammer fixings then had a plaster skim the walls. As expected lots of condensation as the plaster dried out. Its been two weeks and plaster seems to have dried nicely and all condensation on windows and roof has cleared. The problem i have is on the single brick dwarf walls, condensation still builds up and runs down the wall in the small void created by the adhesive and pools on the floor. Ive not fitted skirting or window ledge yet.
Now for my questions
1. If i fit the skirting and ledges creating a void of none moving air, will this prevent the condensation as the air in the void will be different temperature to the inside temp and the out temp?
Or
2. Could I squirt expanding foam into the small void created by the adhesive in the hope the thicker wall with no void prevent the condensation?
Or
3. Neither of the above and do something completely different that hopefully someone on here will tell me.
Thanks in advance
Colin
