I'm painting an new kitchen extension (and garage conversion) with screwfix's new plaster paint (doesn't need thinning) but I'm just wondering if there is any advantage in painting hidden plaster? We're having a kitchen installed so lots of the kitchen will be hidden. Is there any point in painting these areas or am I just wasting time/money I don't really have (I've got lots to paint including a bedroom and large garage conversion!)? Anyone any experience in this?
Also any experience in drying new plaster - some of it has been 8+ weeks and still wet (even more so around the metal edging strips in the plaster). Wet cold weather isn't helping so i'm tempted to try a heater and/or dehumidifer... There is good airflow as the garage door still hasn't been replaced but it's not really helping.
