SEALFLEX is a high- build, heavy-duty, flexible and elastomeric waterproofing system for walls. It is especially designed for exterior use under a variety of conditions.SEALFLEX provides the substrate with a strong and durable membrane that protects and waterproofs. The membrane, which can bridge small cracks, has excellent tolerance to movement  and micro-cracks within the substrate.

SEALFLEX is ideally suited for substrates such as concrete  or plaster that contain hairline or shrinkage cracks. SEALFLEX incorporates the latest surface coatings and waterproofing technology and is available in a wide range of decorative colours and finishes.


The SEALFLEX system is multi- layered system that consists of a primer, an elastomeric bodycoat and a durable protective topcoat.

  • Primer

The primer prepares  the substrate for the system and also ensures a good bond between  the substrate and the system can also bind and strengthened the surface. The type of primer used depends  on the substrate and its condition. There are many specialized primers available.
