Before waterproofing:

  • Check if the roof already has a previous waterproofing system. It is important that, if the slab was already treated, the new product will be compatible with the one previously applied.
  • Determine if the slab is flat or inclined. The emulsified formulas are not suitable for flat slabs since even the smallest ponding can re-dissolve the system.
  • Consider the type of climate in the area where you live or apply the waterproofing. If it is a place with a cold or extreme heat you have to use specific products for each situation.
  • Thoroughly clean the area to be treated before applying the product. The surface must be free of dust, grease, water, cracks and loose parts. The concrete should be moist but not waterlogged.

Generally, it is used as a complement to liquid waterproofing systems, in roofs, seals leaks and is useful in humid areas.
