Why do some bricklayers cover their work in hot weather?

I've seen brickies laying brick, block and stone on various occasions in hot weather. They put a wet hessian sack over their work after they're done. Why?

Hi there,

The reason for this is because the sun dries out the cement too fast and makes it go powdery.

Thanks Paul

Hi, This is so the hot weather doesn't dry out the mortar to quick and cause cracking, which will result in a weak product. :)

This is a practice used to delay the rapid drying of the mortar, which will cause poor adhesion between the bricks, as its the moisture in the sand & cement mixture which creates the bond. the hardness of motar is created by chemical process not by the drying action.

This is carried out in the summer month,s to stop the mortar drying out to quickly in the direct sun light and to stop it from cracking or powdering. As in bad weather it is covered to stop the rain from washing the mortar out of the joints.

In the summer months, this is to slow down the drying process, were as in the winter is to protec against freezing. i.e. frost and low tempretures
