On new concrete slabs it is recommended to use StretchSeal membrane covering the complete slab to help strengthen it and to absorb movement and hairline cracks that may appear.
The membrane is embedded using Repello. Repello gets absorbed into the sub-straight where it cures in the pores of the surface, sealing it and forms a protective film that has excellent adhesion qualities.

Step1 – Concrete Roof Slab
Clean the surface of the roof slab and make sure it is smooth & free from debris and loose or flaking particles.
Step 2 - Priming
Apply Penetrar to the concrete roof slab. Penetrar will penetrate the porous concrete, bind any loose particles or dustiness. Penetrar will strengthen the concrete surface, seal it, and enhance the adhesion for the waterproofing system to follow. It will dry quickly in hot weather but allow 30 min to an hour before starting with the waterproof coating.
Step 3 – Membrane
On new concrete slabs, it is recommended to use StretchSeal membrane covering the complete slab to help strengthen it and to absorb movement and hairline cracks that may appear. The membrane is embedded using Repello. Repello is a polymer-based product used to seal & protect concrete. Repello gets absorbed into the sub-straight where it cures in the pores of the surface, sealing it and forms a protective film that has excellent adhesion qualities. Allow 1 to 2 hours to dry.
Step 4 – Waterproofing
Apply 3 layers of HydroSeal HF over the entire concrete roof slab. Apply using a block brush. Alternate the direction of each coating. Allow time between each application. Each layer must be touch dry before applying the next coat. HydroSeal HF is a co-polymer, high-performance universal waterproofing membrane specifically developed for long term protection of all types of roof surfaces, concrete roof slabs, parapet walls, tiled roofs, valleys, ridges, vents and flashings.
Step 5 – Curing
It is recommended that the waterproofing system must have at least 4 hours to cure before being exposed to light rain. Allow at least 48 hours before flood testing or heavy rain. The product will fully cure and reach optimum strength within 7 days.
