What's the difference between real stone paint and the external wall putty used in ordinary paint?

True stone paint is currently more popular outside wall decorative materials, it not only has a stone-like decorative effect, but also more popular than stone in the cost and construction and maintenance.
other common coatings, such as real stone paint and latex paint, have any differences other than decorative effects?
01,
color, real stone paint can use dark putty. And ordinary paint is generally white or slightly yellow light-colored putty, if dark, then the coating cover has a higher requirements

.
02, flatness
ordinary paint for flatness requirements are higher, only putty layer flat, paint on the wall after the flatness can be guaranteed. And the real stone paint because it has a certain leveling function, relatively speaking, the requirements are lower.
03, polishing
if part of the wall area is not good polishing, it will lead to the paint on the wall after the matte and highlight effect, the wall effect is not uniform. True stone paint generally does not need to be polished.
04, putty layer hardness
ordinary paint on putty layer hardness requirements are not particularly high, if the appearance of a small area putty layer hardness is not enough, but also because the paint seeps into the putty layer to produce anchor bonding and improve. However, the real stone paint on the putty layer hardness requirements are higher, otherwise it is easy to de-layer the problem.
05, flexible
coating layer for thin organic matter layer, by ultraviolet rays, temperature differential stress, freeze-thaw cycle is more affected, and the coating and putty layer is closely linked, therefore, putty layer also has to have a certain flexibility to resist all kinds of destructive stress.
real stone paint is more flexible for putty, because its own flexibility is better, if the flexibility of the putty layer can not match, it is easy to resist contraction is not equal resulting in cracking.
06, bonding force
coating layer because of the light load, so the bonding force of putty layer requirements in general.
but the bonding force of the putty layer is very high, because if the bonding force is not enough, it is very easy to cause the real stone paint with the putty layer at the same time out of the base.
