Adding texture to masonry paint

[Xen]

Hi,
I've just done the first coat on a rendered wall with Sandtext textured masonry paint. The colour is perfect - exactly the shade i was looking for, but the texture is really really fine. Is there anything i can add to the paint for the second coat to give it a coarser texture? I don't really want to have use a different paint as this is just the colour I wanted from all the testers I tried.

Add some fine sand to it..not too much though
