im just after some advice as ive had a problem today with rendering after a dpc. 7 days ago i put the scratch coat on and with the house being empty for months ive had 2 dehumidifiers on to get it nice and dry for the top coat. today the walls looked nice and dry so topped them off, after a couple of hours in about 5 places the render started to turn to p*ss and slide down the wall. these 5 places were all at the bottom and about a foot square. the rest of the walls also dryed up very slowly as i had to go back at 7.30 to give it a good hard rub up and rule off and the gear was still pretty soft. do you think its just the weather / conditions and is there anything i can do to speed up the set without effecting its water proofing propertys ?
