Textured paint

Here's something that didn't exist when I first started making models - textured paint. I found this is in Halfords while getting some primer and after all the PVA and sand work I've done this sounded interesting.

Just to start with I thought I'd see how it looked when sprayed on a few different surfaces. 

Plaster

WOOD

cardboard

The pictures above were taken seconds after spraying. First impressions are OK, it's basically paint with sand in it (not sure what I was expecting). It sprayed OK, smells awful. The sand particles are very fine and you don't get a really high density of sand particles after one coat. The can recommends several light coats and 10 - 15 minutes between coats.

In the interest of fairness, I also re-coated after the first coat was dry, just to see how much difference it might make. The results are down below. A definite improvement, I think.

The picture on the left is a close up of the texture on the building after one coat and two coats on the right.

Can anyone name the kit the bluewheel comes from?

In summary - it's ok, a bit interesting. I do like the texture but even after this one experiment the can is definitely lighter - so I don't think it'll go that far, especially if several coats are needed. I think I'll try it on my current project which is an extension to my previous North African board. I can see it working well over an already based and sanded and probably primed terrain. I think it might also add interest to buildings.

Of course, Halfords sells car paints, this was in the car paint section - none of this explains why you would spray this stuff on your car?
