Morning all
Just trying to retain as much heat in my small cold rooms in the house, the two external walls are back brick as per pic. They are dusty now - whats the best way to seal them before i foam insulated plasterboard up
Could i use thompsons water seal which someone's recommended to me, or am i best just brushing as much dust as i can and them use plasterboard foam and crack on.
Thanks for any advice
