How do you close 100mm cavity at the bottom of the door? I have used a cavity closer but this is not strong enough for screed

2 Answers from MyBuilder Bricklayers

the old tradition was to use slate solid and strong enough to accept screed... cavity closer is flexible so not recommended..

Use slate and its never good practice to use cavity plastic closure near a door way as the plaster tends to crack with the continue of the door opening but it can be used for windows.
