You may think that bricks need to laid with cement, with a simple unit like this yeso rapido is more than strong enough to bind the bricks and shelves. First the unit was built up then spot yeso'd to join it together.
Shelves simply resting on two screws, then plasterd in to secure to the wall
Total time for the job was around 5 hours - most of this waiting for yeso to dry before painting. So we have ended up with a practical storage unit for less than €20.00
Tip: when using yeso with bare bricks, wait until the yeso becomes very thick before filling over the ends - the holes that run the length of the brick are quite large so need to be filled with a more dense plaster.
