Form, pieces of concrete

Work begins with the removal of the old coating. If it is a cement screed, it needs to be knocked down and taken out. The same goes for a wooden floor. The cement screed is best shot down with a sledgehammer. You just hit it from above, while cracks form, pieces of concrete also exfoliate from the base. You collect them in a bucket and take them. Wooden floors are dismantled with scrap, nail and hammer. Pour the black screed. This screed does not require accurately compliance with levels. But do not allow too large differences, so as not to complicate your work subsequently, so it is better to order an ABB RCD. A sand-cement mortar or skew-cement is suitable for a rough screed-not fundamentally.
