Heat retention through masonry paint
JackLouis99
| Posted in General Questions on
Hi there,
I was looking for some advice. I came across a masonry paint that claims to provide heat retaining qualities by preventing moisture absorption while remaining breathable. Has anyone had any experience with this type of paint and would it assist in retaining heat? – https://emperorpaint.co.uk/exterior-wall-protection

It may well do a good job with waterproofing, but I wouldn't think of it as doing anything to "retain heat". You really need insulation to retain heat, paint alone isn't going to do anything in that regard.

The Energy Saving Trust has a statement here: https://energysavingtrust.org.uk/products/properla-emperor-paint-exterior-masonry-creme/
It doesn't support the paint company's 6 degree C statement as far as I can tell. Maybe that test is somewhere else. The statement does suggest the paint prevents most water absorption when applied to a particular type of brick cladding. So dryer brick is warmer brick, I guess.
