Generally speaking, there are two types of screed:

• A semi-dry, hand-applied screed, trowelled to finish
• A liquid, free-flowing screed usually pumped over the pipes to a prescribed minimum depth

Regardless of the type, the process is completed by the screed curing and a wearing surface floor finish, then installed to complete the floor zone. When applied over underfloor heating, it is vitally important to let the screed cure before gradually pre-heating the floor as part of the commissioning process. Once this process is completed, the floor finish can be applied.
