Self-Leveling And Why It Is Necessary
Self-leveling and why it is necessary
In September a Health and Safety study was released reporting over 1 300 injuries related to work condition. Over a quarter of those cases were caused by uneven floor surface.
That is why a leveled industrial floor is vital for the well-being of the employees. The Flooring Group Ltd recommends all large areas of foot walk or industrial use to be unified using the latest compounds and products on the market to save up tons of efforts and money.
To put it simply – self-leveling is mixing the compound with water and then pouring it over the uneven surface. The new layer will protect and smooth, fill in any imperfections and serve the initial purpose. There a few steps to getting the process done correctly;
Groundwork testing and priming
- The new leveled floor will never be as durable as its foundation. So it is important to evaluate the surface with a tensile test. The compressive strength of the subfloor beneath must be greater than 25N/mm2. Also, the flows of the subfloor (such as holes and scratches) must be removed – via grinding, milling, brushing, etc. Then the need for priming the floor comes into play. That process will be needed to secure full coverage of the self-leveling layer and improve its adhesion.
- Perfect measures and equipment
Measuring the primed floor is vital for the application of the self-leveling layer. Thus the calculations will be made exact and the proper amounts of materials will be used. It is important to consider that the data sheets of all products do not include waste or floor roughness as practical considerations. Also, only clean and pure water should be used. To stir and mix the compound with the water it is better to have suitable equipment at hand.
- The application process.
After mixing the next step is to pour the final product and spread it with adjustable pin-leveler. The rule is “to keep a wet edge”, meaning spread material on top of material before it hardens and dries. This is where professional companies such as The Flooring Group Ltd can help. Significant time lapses may leave waves or bubbles and other uneven areas that are to be avoided.
And to finish with, we would like to stress that this process does not equal new floor installation. It is referred to the improvement of the existing subfloor.
