Good morning. I have a condensation issue on my main bathroom interior stud partition wall which has been painted in a hard-wearing easy wipe-over emulsion and is in good condition. However this paint is cold to touch and is the main reason for the condensation issue. Grateful if you could advise whether one of your ant-condensation paints would help; and if so could I overpaint the existing emulsion, and what preparation would need to carry out beforehand? - ie rubbing down or clean with sugar soap etc. Thank you for your help.

We would recommend applying Zinsser Perma-White Interior. Thoroughly clean down the surface, lightly sand to remove the sheen on the existing paint, prime/stain block if required and apply 2 coats. The paint comes in 4,000+ colours so can be matched to your existing decor.
Full application instructions are available on the product page and in the downloadable data sheet.
