Screeding is basically the application of a mixture of cement and graded
aggregates on the concrete floor base. Screeds are of various types and have to
be chosen according to the application and need. After the screed is applied,
no matter whether it is a concrete screed or liquid screed, it should dry and
settle completely before doing any further process on it. After the screed is spread on the floor and after it
is settled and dry, floor sanding is required to be done before installing any
finishing floor above it. Floor sanding is done so as to remove any laitance
having loose surface and various surfaces of the floor seal with each other
effectively. No matter what flooring is to be applied later, but floor sanding
above the screed floor is recommended for all. Liquid Screed Floor Sanding
Limited is a company which provides floor sanding services.
The process of sanding is done by using specialized
machines and is best done by professional service providers. Before commencement
of this process, firstly, the entire floor is cleaned to remove any sort of
nails or other sharp materials. These sharp materials can damage the sanding
machine. Usually drum sanders and large belt sanders using coarse grit papers
are used for the first cut in the initial stages. Apart from the broad main
floor, the narrow regions like corners, edges and stairs remain. The process of
sanding is done for them using edger sander and coarse grit papers of similar
grit used initially. It is in this stage that holes are filled or boards are
cut. A second cut is then carried on using the sand papers having double grit
than used previously. After this is done, a finishing sander or a finishing
machine is used to give the final touch. Finally, the sanded floor is sprayed
with sealants. Sealant can be chosen depending on the flooring to be used
afterwards.
