Double arm 12 inch frame , Hamilton green medium pile roller sleeves, any scuttles just make sure they take a double arm roller but for me personally go to a dulux trade centre as their gear is no more expensive than the rest and nicer to use.

Karndean looselay and longboard are @ 4.5mm thick and can be glued down albeit with their tackifier.

Lots of Karndean are actually thicker than you stated so just keep an eye out.

Welcome , plenty of knowledge on here not from me though and good luck with your build

Looking good.

Have you tried turpentine ???? I have always had good results with this .

+1 for that being a possible reason, my dad was a bricky his entire life and often spoke of this .

Ever heard of a hospital job it could be yours, Through various trades I heard this spoken often as the tradesman would take the job on and use it in emergency s only i.e: if they were let down on their current job with materials being late or other tradesman not finished so they couldn't do their work or a rain stops play work day then it would be lets go to that job and keep him happy for a day . On a serious note I feel for you and its not good practise when they don't even contact you.

+1 for Nitrile gloves. Unigloves kooltouch are a little thicker and less prone to tearing.

Needs must but since telescopic steps over stairs is never a headache.

For stairs and I have been in a domestic and commercial setting for over 25 years you can't beat a telescopic ladder for stairs . Before they were invented I looked pretty silly taking one half of a full size double ladder through the house to use .

Nightmare when somebody paints upvc there is ways and means to overcome this but the cost of products ,you have made the right and quickest approach - just replace it.
