It is essential to make sure that the RCC Concrete surface is free from any cracks, debris and major unevenness prior to the coating of Ressicoat X-491. Hairline cracks in the RCC Floor can be treated using Ressi CFM Flexi 2K.

Ressicoat X-491 is to be lavishly applied over the surface. A primer coat can be applied first if the surface is too porous. A Primer coat includes adding an additional 3 to 4 liters of water in a 16 KG kit and 4 to 5 Liters of water in a 20 KG Kit and lavishly spreading it over the lean concrete surface so that the material is penetrated within. Once the primer is done, Apply 2 neat coats of Ressicoat X-491 in opposite directions (First coat from left to right and second coat from top to bottom).

Waterproofing System for Roofs and Balconies

Once the coating is done it is recommended to take a food test of the balcony to make sure that the area is water tight and the coating has been done properly and that there are no leakages. Once the flood test is passed, the coated RCC surface should be covered with a floor screed sandwiching the coating between the RCC concrete and the floor screed. It is essential to make sure that the floor screed is poured in a slope formation towards a drain point so that the rain water is not standing still over the surface and flowing towards the drain points.

It is also recommended to make a chamfer between the floor screed and the balcony wall to prevent any water leaking from the joint. The chamfer can also be made prior to the floor screeding works.

Over the floor screed a treatment of the desired floor finish such as tiles or any other treatment can be done.
