Special care in the application of waterproofings FAQs

1) Storage

These products must be conditioned in fresh and dry places, protected from rain and sunlight, as well as from wet areas or sources of heat irradiation. They should be stowed in pyramidal form, taking care not to exceed 6 rolls of height per row.

2) Evaluation of the surface

It must be checked whether the roof surface fulfills the necessary conditions for the execution of a waterproofing system, otherwise the time must be allowed or adjusted. Interruptions in the execution of the roof must be made in such a way that no The component materials of the same deteriorate.

3) Weather conditions

Waterproofing work should not be carried out when climatic conditions could be harmful or there is an imminent risk of its occurrence, particularly when it is snowing or snow on the roof, when it rains or the roof is wet or when there is strong wind. Work must be performed when the ambient temperature is below 5 ° C or above 35 ° C ( below 41 ° F or above 95 ° F  ). Any damage that causes leaks should be repaired immediately by specialized personnel, with footwear and appropriate safety measures.

4) Maintenance

Proper maintenance of a membrane contributes to the durability and performance of the waterproofing system. Periodic inspections (at least once a year) should be carried out to verify their condition, taking into account the following operations:

5) Condition and conservation of the load wall throughout the perimeter of the waterproofing

Remember that any fissure in the loading wall - outside the waterproofing area - even on its side profile, can extend to the interior of the masonry, below the visible area, allowing the entry of water or moisture. In this sense, it is recommended to remove loose parts, repair, seal with waterproof material and apply Emacril, acrylic roofing waterproofing, and / or Emacril Muros.

6) Membrane fixation and adhesion test

Note that poor adhesion is likely to reduce tolerance to high impact, punching or other undesired mechanical effect that can attack the surface.

7) Maintenance of protection

Detection of scratches or areas of asphalt exposure - on the surface - by external mechanical action.

In the case of membranes with self-protection aluminum cover, any area that has deterioration must be repaired by applying FitaFLEX, a self-adhesive membrane. The areas of asphalt exudate should be protected with Macá Al, aluminized paint.
In the case of membranes with a self-protection cover made of polyester geotextile, any area that has deterioration must be repaired by applying a membrane cut of similar characteristics, applying Emacril, acrylic waterproofing for ceilings, as a termination.

In the case of membranes with a mineral self-protection cover, any area that presents deterioration must be repaired by the application of natural slate scales (provided with the product at the time of acquisition) by adhering them, with the contribution of heat, to the surface at In the case of membranes applied under a folder, it should be noted that any future fixing of objects to the floor involving the use of screws, screws, etc., will reduce the waterproofing capacity in that area.

It is very important to allow the free flow of water, removing any foreign element that contributes to its stagnation. In that sense, leaves, verdin, mosses and other invasive plant forms, as well as snow, materials and sediments accumulated by the wind that can promote reservoirs of water accumulation or obstruct drains and gutters should be eliminated.
