Here is a new square set opening. Framed with external angles, 2 x base coats and 1 x top coat. You MUST scratch/scrape plaster down between each coat, usually just before it fully sets.
There’s the square set opening in the background with the external angles on before it’s trowelled. Remember to use a level and builders square when installing or they can look really bad when painted

Right. i am at work at home and i’ve just taped in the corners. These are called in the trade internals. As you can see on the left photo that is a taped in internal. you put the plaster on both sides then you put over that the paper tape which you fold(it has a fold line in the centre of it). Once you have that in you blade it off with a 3 inch (angled) broad knife so you don’t spread the plaster to wide. And that’s it you have a taped in 90 degree corner which later on you top coat with a 4 inch blade and a special corner tool. i will explain that later.
cheers

Ok. I just sanded this job. Notice the 1m wide Butt Join in the Ceiling. I had to trowell this that wide because the owner sheeted this ceiling and he put the join 4m long in the centre of the ceiling. This is not the proper way to sheet. Butt Joins are always staggered at least 600 apart so they are easier to hide when the lights turn on. This ceiling will still be ok because of how wide i troweled it, but usually it shouldn’t be this way.

Ok new job today with something new to explain. I am working here at the St Helens Anchor Wheel Motel and i need to sheet PAINTED brick walls. This is known in my industry as Bonding.
The picture on the left shows a brick wall that has been prepared to sheet. The right when its done. Now to bond the plaster to these bricks, first you must grind(use concrete cutting disc) the paint off back to original brick, because it will not stick to paint. Usually every couple of 200ml spots will do. Secondly you must mix water with bond crete(special bonding agent), and then mix that with cornice adhesive to get a sticky consistency. Once achieved you grab your 4inch blade and put daubs of the mixture onto the grinded back areas.
Its advised you have all sheets cut and ready as the mixture sets quick, once all sheets placed onto brick wall, hit them hard with something straight, no not your level, i use a 2m steel tube, as you can see in background, and your done. You can prop the bottom with timber till mixture sets to ensure architraves go on straight. So thats it you have bonded brick walls and they will not fall off. 🙂
