I would be concerned if i was you, if its getting damper over night they look like cold spots and if this is happening at night when its colder you have problems.Hi , new to forum. The above pic is in my new extension. It has been correctly built with double skinned block and insulation. Everywhere apart from the dab marks has dried perfectly. It was boarded and skimmed 6 days ago. I am getting concerned because the damp spots don't seem to be getting any drier each day. They fade a bit throughout the day and then come back damper overnight . Any comments or advice appreciated. Thanks Andy

how is paint gonna stop the damp coming through?I've had this loads of times, just the dabs drying out. You can paint it, you will cover it no problem with a good quality paint e.g Dulux Diamond Matt.
What will injecting do? I thought your first comment on this thread about painting with gloss was stupid but this is worse.I misread that actually your building is still damp could be a problem with the damp proof course your best bet is get a dehumidifier in there dry them out. If all fails yours next point is to address the damp proof you may need to inject.
Have the facias and roof been put on?Yes, it was rendered yesterday. But it's a double skinned block wall with the required insulation between.
Got any pics of the outside? or any of the build as its happening?Yes, it was rendered yesterday. But it's a double skinned block wall with the required insulation between.

roof insulated with celotex what about the walls?Facials and fibreglass roofing system on Before boarding and plastering done. Insulated with celotex. Roof lantern not complete yet, just covered with polythene so probably getting cold in there at night which might not be helping drying
Do a google search on that im not 100% certain thats what should of been used.Walls with celotex too
