House of expanded clay concrete blocks 40cm, plastered on the inside, in the rain the walls inside are wet! Because of financial constraints, the foreman proposes to plaster the walls from the outside and primer and do interior decoration (go inside the house), and in a year or two to insulate the house and apply decorative trim. Can I do this? I'm afraid that in a year or two the interior finish will be ruined.
Can I do the interior of the house first, and only after a couple of years to do the insulation of the facade?
It's cheaper to glue EPS and reinforce right away. Decorative trim should be postponed until better times.
I often see lodges wrapped up in cheap windproofing for a long time. You might want to look in that direction.
Try plastering without insulation.
Rainwater won't get in through the plaster on the wall. If you still see wet spots after plastering the walls, look for leaks from the roof or around window openings.
