Can you do brick work in the rain?
In respect to this, can you lay concrete block in the rain?
Do not wet the blocks before installing them. Wet blocks expand, then shrink when they dry. If it rains or rain threatens, cover the blocks. Spread mortar only on the outside edges of the block (a technique called face-shell bedding), not on the cross web.
Subsequently, question is, can you do masonry work in the rain? In general, I do not recommend building masonry walls during rain. In most cases, it is more cost-effective simply to call a rain day than to proceed with work during rain. However, masonry can be installed in the rain if the walls are covered under a temporary shelter and the materials are protected from rainwater.
Keeping this in view, how do you protect bricks from rain?
During breaks in construction, take particular care to keep bricks and brickwork in progress covered with waterproof sheeting. If overnight frost is likely before the mortar within newly constructed brickwork has fully set, it should be protected with an insulating layer of hessian underneath the polythene.
