Hi

Just wondering the best way to airtight the junction between the floor screed and external walls: I have 1 inch of insulation between the screed and external wall.

I’m thinking tape won’t adhere to well to the screed, fleece and airtight paint another option?

Anyone fitted the airtight hoods for downlighters with no access from above? Flat roof minimal void.
Should I install them at the same time as the membrane and just let them sit in the membrane until the slabs go up?

Thanks
