Hello... I have plastered lots.... what I will say is that you should always use either the paper or the sticky netting tape... never do it without cause it will always crack when the summer is a scorcher or the winter is a freezer.. Always fan out at least 15cm each side of the tape when the joints are cut joints. Never try to do it in one coat... always just give it a filling then do the smooth coat. Use a wide scraper about 10 inches wide. Use paper tape on inverted corners and sticky netting tape on all others.. and use the metal corners on outer corners. Enduit is available from lafarge.. 35...is fast drying..45 medium and 55 is slow. lafarge is the best make.... I have used many. The ready mixed stuff is not worth the saving. For an all over plaster there is something in france called Lettuce 2000 ( forgive the spelling ).. Ok this is not gospel but it is according to me and I have plastered over 30 houses in my life.. Hope this helps...even more music...
