Normal sand and cement used with a sp11

Hi there I'm looking for advice on using a normal sand and cement mix in a sp11 spray render pump do I need to use any additives to help it flow I tried it once before and added free flo but the pump kept backing up.

If there is a pump you can use for s&c that’s for sure diesel, apart from @theclemo ’s f**k**g Ritmo of course :p

Its down to the sand u get tbh. Extra feb or waterproof will help. Have the mix to wet for a Hawk. If that makes sense.

The man is right, good uniformed grain sand and don't be shy on feb, diesel pump like a P11 horses it on.

Thanks for the reply how much extra Feb buddy,hope I don't sound stupid I usually cut the bottom off a 1.5 volvic bottle and pour in about 50 to 60 mils and what ratio of sand to cement to you use this is my first time using this pump kind a lost at the moment
