Sorry need one more post to see this....

Yes. I also think it would likely be unsuitable over some of the other chalky finish coats f&b etc.

Yes, it does a grey job of staying on tiles/windows etc once dried. Unfortunately just not on top of contract Matt paint!

Great, thanks.

Now planning on using zinnser guardz on the problem patches to try to sort it out.

Actually, the instructions on the paint are quite specific that you must use the scrubbable paint for the mist coat.

I had this problem - mist coated (with airless sprayer) using cheap contract Matt. Then applied matt scrubbable paint which is flaking and coming off in areas. Learning point for me - no more cheap mist coat.

Hi, is the anemometer still available to hire? I need to balance my MVHR. Thanks, George

Cheap and cheerful, but it worked well.

Hi - I'm looking to fit mineral wool or similar between pitched rafters. Is there any reason I can't use Knauf Loft roll instead of frametherm (ignoring u-values)? Will have vcl, 40mm Kingspan and then plasterboard below. Thanks!
