I was just curious why thistle unifinish was drying up on the shelves of retailers so came across this forum to find lads and ladies having issues with it failing to take to backgrounds.
First time i used this was to skim a full 3 bed bungalow with a newly erected summer room 18 months ago. This included ceilings and walls over plasterboard, fresh backing plaster, painted surfaces and bare plaster. Ive got to say it all went on a dream and never had any shelling or cats facing. The only time i used PVA was when the background was made up of diferent backing and this was just to even out the suction as it recommended
