If the real stone paint falls off in pieces, there are several possible reasons:

One: Improper handling at the grassroots level

Too much ash on the wall will affect the bond between the wall and the mortar layer.

Before construction, remove loose surface and floating dust to ensure that the wall is solid, flat, clean, free of hollow drums and dirt.

Two: Use putty for leveling without mortar

Because the combination of real stone paint and putty is not high, real stone paint should be leveled with mortar.

If you encounter an unprofessional construction team and level with putty, it will cause large pieces of real stone paint to peel off .

Three: Once the mortar is dry, apply the second time, and then apply the primer if the mortar is dry

The length of time for the mortar to dry completely has a great relationship with the climate conditions at that time.

If the weather is good and the air humidity is not high, the time required for the mortar to dry will be shorter, otherwise it will be longer.
In good weather conditions (when the temperature is around 25°), the mortar will generally dry out in three hours once, and usually twice a day is enough.

Four: The primer is useless or the quality of the primer is not good, which is not effective

The function of the primer: First, it seals the alkali to prevent the alkali from penetrating into the surface layer and affecting the surface visual effect.

The second is to solidify the bottom, penetrate into the base layer, tighten the mortar, and play the role of connecting the mortar and the real stone paint.
If the primer cannot fix the mortar, it will lose the function of this code, and the real stone paint can be torn off the wall after painting.
