Knauf Presto Scratch Render

Hello.
Has anyone else used Knauf's Presto range recently?
Knauf say that it is designed for next day scrape but it is absolutely bolt hard. Trying to render the same day with this material is equally as difficult as we are still on site at 8pm as it is not curing quick enough!!
wondered if anyone else is struggling and has any recommendations to help, other than using a different product.
Thanks.
 
Must do everything to help the product when high temps !
Reduce suction to substrate
Spray late and wet
Spray with water when leaving
