What if it rains after rendering?

Exposing render to rain, whether you’re working in it or having rain fall directly on newly applied render, is going to create problems with the colour and texture consistency of the finish. Excessive amounts of water can affect the bond adhesion between the coats which can lead to more serious issues.

These scratches improve adhesion and make it easier for the second coat to bind onto the surface, forming a tight, secure bond with a level finish. Without this coat, the render is more likely to crack and ‘blow’, which means that there is air trapped behind.
