Rendering with machine

[Ollielake88]

So I’ve been hand balling mono for a few years recently bought a m200 done a days training with Andy at plasterers one stop shop Im just wondering if most people use the same process 15mm beads spray one coat mesh then spray another coat on top and if rendaided and meshed prior do you still do in 2 passes or try get in one? Appreciate any feedback thanks

One 17mm pass on rendaid will sag like f**k with most materials.
I like to bed mesh in 5ishmm then top with 10ish.
The first pass will take a second quite quickly on rendaid in the summer buy obviously not so much as it gets colder

Thanks for the reply. So you wouldn’t put the mesh on with the rendaid?Yeh I did think one pass wouldn’t work as on the training day was spraying real wet. Is rendaid something you would spray on or just hand ball on?

You got it right first time round

You mean stick the mesh in with the rendaid? Never tried it but then the mesh isn't part of the render, you'd essentially have one thick sheet of render sat ontopnof mesh rather than the mesh re enforcing the render.
I've also never tried spraying rend aid. Suppose you could but I wouldn't fancy it

f**k**g spray the lot man, spray your rend aid mesh it stipple it top it with your wank mono and bobs your grandad

Mesh as close to the substrate as possible. That's what the guys on the weber training course told me

Put it on with the Rendaid if poss, if not put it on in the first pass

 

[Ollielake88]

Yeh when I hand ball I just throw mesh on with the rendaid if I’m using it. Just curious if machine guys do any different

Thought mesh was ideally a structural assist in base rather than used as an effort for some kind of mechanical key?

If applied with rend aid then the mesh is applied onto, applied in first pass then it's re enforcing the render and adding strength.
Surely adding it to the substrate is basically using it like scrim tape

Mono is wankety wank

What makes you say that just a s**t product or you prefer using others. I’ve only used Webber mono k Rend and fassacouce all seemed the same to me

I use a ritmo m mate one pass Weber but depending on the building I’d also do two passes if it’s needed only small jobs mainly after hack off
I’ve never seen an m200 spray one pass though like you say they always spray really wet and in two passes on videos I’ve seen

Thanks for reply. So you can spray gear stiffer through the ritmo can you. And one pass with ritmo will cover 15mm beads. If I can get on with the machine might have to look into one of them. One pass must be so much quicker

 

[Hhj]

If it's a new meshed spec then it needs to be done in two passes, if it's a reno/hack off meshed rend aid is essentially your first pass,
spay in one pass on new block work as mesh isn't needed but what a dog s**t method that is.

Mesh close to the substrate eliminates risk of rubbing back to it. That's probably why they've told you that. Understandable.


The mesh is always more effective nearer the surface.


Albeit at a riskier cost.

Another reason why mono is inferior to thin coat, you can't apply the mesh in the surface of the system, with thin coat it's only a few mm back from the surface reinforcing the render,
Mesh ain't doing nothing back by the substrate.

No my name's Frank mate.

The M200 can spray one pass no problem.

If people actually take advice from manufacturers - they even state, apply in two passes. Water content is very important to mix consistency and colour.
Most issues with bullet holes appearing when scratching mono will always be when it’s applied in one “thick” pass.

 

[Vincey]

That’s true mate Weber recommend two passes Tbf you’d be better doing @Ollielake88 as @Plasterers1StopShop says ,I know two lads who use a m200 they spray that way too

Yeah mate I have heard thin coat is the best render and can even be patched in apparently but I’ve only done it once so it’s not really something I can offer atm. Definitely want to learn how to doit though. Do you hand apply top coat or spray with compressor?

 

[Hhj]

Got a machine for top coat, compressors, hoppers, everything can mention for spraying 90% of the time still hand apply it's a quicker better finish job, only bother spraying on big commercial buildings.
