CEMIX AQUASTOP is a white, cement based, waterproofing membrane, designed for use on concrete and masonry surfaces in positive and negative pressure applications


CEMIX AQUASTOP can be used as an interior and exterior waterproofer on surfaces including concrete, masonry and exterior use plaster. It can be used as a decorative, white finish. Alternatively, it can be painted over.


• Can be applied to a damp surface

• Does not chalk or dust

• Inhibits mould growth


Varies according to the substrate condition. Approximate coverage per kg of product for concrete 2m2 to 4.5m2, and for stucco 1.5m2 to 4m2.


The substrate should be free of dust, grease, wax, oil, dirt, loose plaster, laitance, curing compounds, paint and all other friable materials and contaminants likely to prevent bonding. New concrete should be left with a wood float finish and sufficiently aged as per manufacturer recommendations.

All substrates should be structurally sound, securely fastened and properly supported to eliminate any movement that may cause cracking.

The substrate should ideally be dry or damp (at most) but not wet.


1. Add clean water to a mixing container. Use approximately 900ml of water per kg of product.

2. Add CEMIX AQUASTOP to the water, mixing constantly with a mixing paddle, until a creamy consistency is achieved.

3. Add further water if required. Do not exceed 1.1 litres of water per kg of product.

4. Allow to stand for 10 minutes.

5. Stir again before applying.

6. If required, stir occasionally while using to prevent the product settling.
