April 26, 20233 yr A family member has asked me to post this on their behalf: Victorian end of terrace house in Cardiff. Has had various damp problems, which have been “fixed” but the humidity levels rarely fall much below 60%. Kitchen is currently being redone and is being plastered. The owner of the house has a dehumidifier on site to aid with drying everything out. Got about two buckets of water out of the air today . He’s worried that the dehumidifier might cause the plaster to crack as it dries. But at the same time, he doesn’t want the 60% humidity in the house to slow the plaster drying as he’s in a hurry to paint. He asked his plasterer who said the dehumidifier won’t crack the plaster. Does everyone here agree?
April 26, 20233 yr Not worth the risk, crack open some windows and get some through air movement. keep the dehumidifier for drying the clothes or after a leak
April 26, 20233 yr Better off trying to create some air movement. Get all the windows and doors open, and if possible hire a big fan and stick it by one of the external doors pointing into the house. Or, just do like Nick Knowles mob, and paint the walls while still wet. Full thick first coat, no watering down.
