A proffessional may not need to worry about the scratch coat, but in the case of a novice, it will i think, be quite important!

Sorry but there is no way you could attempt this if you have not carried out before, Try to get some money together and get a professional in. I don't mean to be rude. The scratch coat and metal beading should be acceptable as this will make the finish coat better to bring to a Nice professional finish.

Put your scratch coat on, and as you say, don't be worried about it. This holds your beads in place. The top finish weaker mix coat is scraped with a straight edge to flatten it and use a square for around the windows. Float off and sponge down as it's setting.

i've seen lots of people ask this type of question and my suggestion from the items in your question addresses a very fundamental point.
you ask about plastering, indoors, and talk about rendering, mostly outdoors. which is it?
whichever it is nonetheless only take this on if you don't mind making a horrible mess of the job, i've seen plenty, and have to take it all off sooner or later. if its later you may cause considerable damage, cement mortar sets really hard and should stick to masonry very well. If it doesn't stick it will crack and maybe fall off, it will definitely let water in and cause damage to your house sometime in the future.
when you learn the craft it's with lime and sand that does not set hard so its easy to take off when you mess up, i mean when. only after much practice and when you can make a decent job of it do you use hard setting plaster.
if you want to learn find someone to practice with or go to an evening class.
you may be someone who has a natural gift to do it right first time, if so you are the first one i've met.
i am not trying to cast a cloud but in my experience please don't practice on your own house, or somone elses! without being able to do it well. Get a pro, one who can prove they can do it to high standards, assuming you want a high standard job? or practice yourself and settle for what you achieve.
may not be what you want to hear but trust me i've seen it.

i normally fix the corner angle beads with galvanised nails before i do the scratch coat as you con see the joints to nail into put scratch coat on all surfaces ........if you dont ..you will see the outline of brick or block in the render as it dries

If it's more than a few sq. ft forget it, I am the last person to discourage you but plastering is a skilled job needing years of experience, you could try on a small area but you will probably be very disappointed, but go ahead, and best wishes.

as a plasterer myself i would advise getting a pro to do it as if done it will look an eye sore + it will cost more to put right if you get a pro to put it right.........hat off to you if you attemp yourself and just remember dont panic
