Removing screed - the right tool makes it easier
The tools needed and how to remove the screed most efficiently are explained in the following paragraphs.
General about Screed
In addition to the later high stability, screed is also characterized by a wide variety of designs. It is made of different materials and with different laying techniques. Most often, cement screed is laid. This is very robust once it has dried out and also resistant to heat and moisture. It can already be seen that when removing screed, much more force should be used than with other means.
When Screed Should Be Removed
Screed is not only flexible when laying it, but also when repairing it later , If, over time, small dents or joints occur, this is usually not a problem and the screed can be repaired relatively easily. Even later smoothing is possible relatively easily. Therefore, the screed should actually only be removed and possibly renewed if the entire structure is damaged. This can be the case, for example, if cracks occur at several points. Also a detachment from the ground or the like would count.
Proper protective clothing
Since the removal is later associated with a great deal of dust, it is essential to resort to appropriate respiratory protection. For the same reason, wearing goggles is often good, so you do not have to constantly clean your eyes. In addition, good and solid steel cap shoes are recommended, as later some rubble clumps arise and also worked with very powerful equipment. Gloves should also be worn. If you are wearing your clothes, you can use old or discarded clothes or normal overalls.
Make sure you have enough comfort when choosing your clothes. The removal of screed is also physically stressful and often very time consuming.
Choosing the right tool
In itself, the removal would work with a lot of hard work with a hammer and chisel. However, this variant is very time-consuming and labor-intensive, which of course discourages it. Therefore, a hammer drill is usually advised. It is a machine that is supposed to break up the surface with regular and strong impacts. However, care should be taken to ensure that it performs properly and is not too strong or too weak. The problem would be that under certain circumstances, the underlying soil can be damaged. Such tools can often be borrowed at hardware stores, making purchasing unnecessary. When renting you can also get some advice. It is also helpful if you use a concrete vacuum cleaner. You can also borrow these many times.
When choosing the right rotary hammer you can orient yourself well by the number of joules. This should be in the range of about two to three Joules to achieve the desired result without damaging the underlying floor.
How to successfully remove the screed
The rotary hammer manages to first wear down the screed. Afterwards this will be broken up. Therefore, it is not difficult in principle. You must hold the hammer in the appropriate places until they are broken. To facilitate and accelerate the work, then the concrete vacuum cleaner is needed. This can be kept next to it and then sucks the debris out directly. This can then be repeated for the entire surface. For small pieces lying directly on the floor and not easily removable, care should be taken not to damage the floor.
Screed is also ideal for installing underfloor heating. Therefore, in these cases it is essential to seek the assistance of a specialist in order not to damage the underfloor heating.
Renovation of the screed
If the screed used to be a satisfactory floor, it can of course also be renewed. In this case, especially the demands on the screed must be observed, so that the right one is selected. Often, insulation and insulation, which previously lay under the screed, must be observed. These can, if they are not damaged, usually continue to be used. The removal also opens the possibility to use completely new floor coverings. These include, in particular, the classic coverings such as parquet, laminate or even tiles.
The removal of screed should only be carried out in the case of severe damage. If it has to be done, it is a very intense job that needs a lot of stamina. The corresponding devices can be borrowed to facilitate removal as best as possible. Afterwards, there are many possibilities to redesign the floor.
A rotary hammer is the best tool for removing screed. This can be used to wear down the screed and thus break up. Afterwards the individual pieces have to be vacuumed before a new floor covering can be laid.
