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.
