Hi and some advice please

[Wonderingdonkey]

Hi all

Was looking for some advice on a product that we are being asked to use Alsecco Stockleputz Lp

We are on a block work construction new build and there is an additional area over stone.

The supplier has stated to use this product with 6 mm beads and mesh it spat it and treat it as a thin coat.

But the manufacturer data sheet says to put it on 10 - 20mm thick and treat it like one coat renders ( treat problem areas lintels etc with an adhesion promoter, mesh and scratch) then put the render on and rule it meshing high stress areas (openings etc with additional stress patches)

Not using it before we tried it on a garden wall to be fair it went on ok ruled really well and did not slump or slide we then left it overnight to float in the morning as we do this time of year with other One coats

We were floating it next day and noticed blisters appearing Im wondering if anyone else has ever seen this with this particular product or any other OCRs

I’ve used a lot of different OCRs over the years but never seen it before.

Merry Christmas to all

Thanks

Did you float it last week when it was minus temperatures

Hi Stewie

It hasn’t dropped that low here we’re still around 6-7 maybe down to as low as 3 overnight but we haven’t seen sub zero temperatures

that being said everything is saturated but you would think if it was overly it would be sliding down the wall when trying to rule it.

The Alsecco render that I have used on EWI, had a base coat with full mesh. A coloured top coat that was applied about 2 mm with a stainless trowel finish. never a float finish.

Yeah that would be more then likely something like there armatop mp or uni

The data sheet reads to apply it like a thick coat render

For example Baumit would be Mc55 on lintels meshed with stress points meshed in the base 1 coat work sprayed in 2 passes


The Alsecco data sheet reads to treat the same but in their products treat lintels with armatop mp or aks with mesh and mess stress points and bang it on like KZP

Alsecco slp is an ocr not a thin coat render. It’s nice gear but does need applying minimum 10 mm thick
