Weber OCR tips?

[Stanbra]

Got a large garage, standard block work for a friend to do. Thinking of trying Weber ocr. Just got a few questions…

Could I use 10mm beads or 15mm, if so the 15mm would you first pass the full panel then drop back and top coat? They’re decent sized areas.

Also would you use a render grip first to help with suction?

I'd go 15mm beads, I normally do one pass and bed mesh to it then second pass wet on wet and rub up.

What blocks?

What spans?

Hand or machine?

What finish?

I wouldn’t use Weber ocr in these temps.

Why use the mesh, just an extra precaution? Wouldn’t normally mesh with traditional s&c

Gona split it up with few expansion beads and I’m hand applying. Think they 7n red band blocks

Also just finishing like normal sand and cement

A couple of days with a pressure washer first , eh?

That'd be my priority.

Once done it's another way of protecting it from cracking that's one, two it helps with doing it in two passes, I normally do first pass at around 10mm thick, mesh, then nice and tight 5mm over the top.

Thanks for the reply. I’ve watched few videos where they’ve used render grip, to help control suction. What’s your thoughts on that?

I’m gona break the big areas up with expansion beads. Doing it on my own with labourer. It’s for a friend and it’s not really going to be seen. So seen it as a good opportunity to use the Weber and bit of experience.

Blast it first.

Those white stains are s**t.

As is the green.

Looking at those branches - I imagine there's alo of greenery surrounding it. Been left a while.

Definitely at least a full day blasting it.

Then grit it if you like.

I'd go minimum 12mm, or you'll get block lines showing.

Work in the shade.

Start on a couple of small sections until you know the timings.

Unless he's a friend you don't like.

Appreciate the advice mate. Tried my very best to get out of it. He knows I’m not confident, and isn’t too fussed. Just seen it as a bit of experience with the product:

When you bed the mesh in is this first or second coat

f**k me it’s like panic stations lol

Base for me, though I've seen it done well in the top.

More importantly, they say the closer to the front (the finish) the more effective it is.

Personally, I like it in the middle, bang in the middle of the total thickness.

 

[spunky]

I’ve only used it a few times I’ve seen videos of lads bedding it lightly into the top coat and floating it through not sure if it’s for a bucket coat finish but I can see that being pretty hard work if it was float finish in the summer and you’re against it

I bed it after the 10mmish first coat and then tight 5mm over the top. The closer to the face the less chances of it cracking.
