Scratch coat still soft next day?

[Stanbra]

Don’t do much of it, and just helping out friend.

Scratch coated yesterday using 4-1 with feb plasterciser . Didn’t realize but the cement we’ve used had plasticiser in already. (Master grade cement)

Came to mind top coat and still relatively soft. Could scrape off with scraper.

Should I leave to cure few more days before top coating.

Has too much plasticiser caused this?

The scratch coat needs time to cure, leave it about 7 days.

Cheers. Do you think the plasterciser caused this?

No, it is not a time of year for the render to dry.

No, it is not a time of year for the render to dry.

Just out of curiosity, and if you’ve got the time, what’s your method to s&c rendering?

The man I used to work with was:
4-1 with plastersicer top coat
5-1 with waterproofed top coat

Sand and cement render went out with the Ark! I only use OCR bagged material.

Yes oveplasticised.

Leave it a week. But pop back after coating and dampen - not really soak it.

Strength of mix depends on substrate .
