Dnt think there's any trowling involved im guessing u do ur work as you wud tape and joint then u finish it with airless so no need to paint..never done it or seen it up close..i cud c it kicking off in new schools or supermarkets but it wont roll out to everywhere..if I told builders to go airless instead of skim finish but its guna cost x amount more he'd tell me to do 1 there want the cheapest not the bestToo many variables tho...its like learning the trade again.
Can you go over most surfaces like multi or is it just for boards?
Can you spray over set plaster?
Need to PVA or some other new chemical?
Does it trowel up normal?
Is scrim of no use?
What about sh1t boarding that someone else has done?
Where can you buy it?
Etc. Etc. Etc
