Many times when we go to buy a mud floor, we are offered the opportunity to purchase this ground with a treatment that is either already applied at the factory or it offers a product that is applied to the slabs before placed.
This could are most often the greatest strategy to cease being concerned about needing to clean and deal with the soil floor after it really has been put by building contractors, it really is much less so.
Pretreatments in clay-based soils arrived at match the subsequent goal: The theory is always to prevent a pretreated soil soak up spots through the location method, in order that it works as a protective buffer within this stage.
Comprehending these pretreatments as defined, from the point of view it is completely wrong to the subsequent reasons:
1. Mason If you connect the mud floor, generally the slab immersed in the bath tub just before putting, with the notion that the cement grip much better with this.
Two. Usually pieces of clay is put employing concrete or sticky glue which everybody knows to be combined with h2o.
In one way or another will be an important moisture both in the slab and below this. That is in both cases we find the same situation. For that reason, this moisture may wish to go slowly evaporating from the on the inside for the exterior.
Normally hidrofugantes pretreatments consist chemical compounds which prevents the intake of liquefied, and get sufficient mini pore to permit water loss of humidity. However, the reality that we face is that this is not always the case, as there pretreatments sold as definitive treatments waterproofing the slab 100% avoiding this moisture to evaporate through the slab and whose only exit either through the board.
This can lead to a problem with which we are unfortunately often with pre-treated soils; is that once they have been placed at the time they begin to appear whitish recercos observe that while trying to clean found in the interior of the slabs and we can not access and therefore clean.
The reason for this is because indoor humidity fails to evaporate through the slab to be the pore is fully closed and thus the moisture is concentrated inside the slab forming particles of salt, and we can not access it since the slab is waterproofed mud.
Another equally important issue is that in the best case, where there appears to us any problems as described above, is that the joints between the tiles of clay will not have any treatment applied and therefore the porosity is 100%; so if we want to have our well protected we have to apply a soil treatment also these meetings.
For almost everything explained to date it will seem that then apply a pretreatment to a clay-based soil yet again we have acquired is throwing money apart. Nicely is not really totally accurate as long as it was actually clear that these particular pretreatments operate satisfy.
From our connection with above 15 years cleaning and looking terracotta surfaces, I suggest pretreatments only when there is a very high danger that during the job we can easily stain a floor. That is certainly, if with regards to a work newest real estate with higher personnel turn over (masons,painters and electricians, …) and know for sure that once the earth placed there will be substantial personnel turn over on him and there exists a high risk that it may grow to be discolored through the use of plaster, acids and paint and so on.; then when this happens, you should work with a clay-based pretreatment.
We must also bear in mind the economic factor is that a pretreated clay is going to be a considerably higher payment than buy the virgin untreated clay.
Furthermore, all pretreatments while we made ? ?crystal clear only fulfills the purpose of preventing the dirt discoloration in the job and also in no circumstance are ultimate therapies. This once so complete the task, the first thing to do is go on to the reduction of this pretreatment to access the inner in the slab and completely neat and enable full water loss of dampness, so once free of moisture fully every one of the surface, begin the use of protecting therapy.
Typically once we work on new and recently set flooring surfaces which have not been pretreated function remedy contains two phases: cleaning and treatment; pretreated soils whilst you will discover a stage far more to eliminate such pretreatment: Pickling.
This may suggest that by the additional expense of investing in a mud surface with pretreatment, add more an expenditure nevertheless in the later on job of garden soil remedy and stage etching described previously mentioned.
Therefore, our conclusions and recommendations are:
Because if you have the necessary concerns in the work, does not have to stain the slabs, in most cases it is not necessary to buy slabs of pretreated clay. The danger of staining emanates from getting hit silicone, oils, acids and paint etc.. However dust and normal traffic will not affect at all the mud.
Think that clay-based garden soil is a fine pavement surface area, ie, no-one would ever place a wood floor or shiny marble and therefore the painters, plasterers, and so on; may not acquire correct safety measures in order to avoid destroying it. So the mud is equal, the ideal is that the placement of it is one of the last things in the works.
In a nutshell, getting standard as with any other delicate area pretreatments are significant extra cost may be eliminated in many instances safety measures.
