CEM 2K (Eco)



CEM 2K Eco is a two component waterproof coating specifically designed for use on roofs, water tanks, water retaining structures as well as in bathrooms, showers, kitchens as an under tile protective membrane. CEM 2K Eco is flexible, safe to use, low in odour and toxic free. The products have been uniquely formulated with special polymer to increase its strength. CEM 2K Eco is based on the most advanced acrylic polymer technology and is totally resistant to re-emulsification.

The substrate must be hard, sound and free of dust and other barrier materials such as paint, lime coatings, plaster, curing agents, laitance, adhesive residues etc., which will inhibit adhesion to the substrate.

Use a suitable Degreaser to remove polish, wax, grease, oil and similar contaminating substances prior to mechanical preparation. Contaminated substrates should be mechanically prepared, either by grinding or contained shot blasting equipment or similar, and be vacuumed clean prior to applying CEM 2K.

NOTE : Any joints or cracks in the substrate where differential movement is anticipated e.g. movement joints, should be brought through to the finished surface.


Individual contents of the CEM 2K Eco should be thoroughly stirred before being mixed together. The entire content of the Part A (5 Litres) should be poured into a larger mixing vessel to incorporate water and powder. Add approximately 2.5 Litres of water to the same vessel and mix for one minute. Finally add the Part B to the same vessel. Mix all the three materials with spiral mixing paddle in a slow speed drill, continue until a consistent homogenous mix is achieved. One or more packs can be mixed simultaneously to ensure a quick rate of installation.

Apply CEM 2K Eco by brush or roller. A medium nap paint roller is recommended. New rollers should be dampened with water before being used for the first time. For best results with a paint brush use a good quality, 50mm long bristle variety.

To achieve the required dry film thickness per coat application must consist of laying the product onto the surface and light finish the surface. Do not try to apply in the same manner as a building paint. A conventional building paint is normally applied at 25 - 40 microns for wet film thickness while Acrylic polymer waterproofing needs to be applied at between 0.8mm and 1.0mm per coat depending on product and application.


Wash hands, brushes, rollers, etc, with water while the membrane is still fresh. Remove cured material with mineral turpentine.

In case of contact with the eyes, rinse immediately with plenty of water and seek medical advice and after contact with the skin wash immediately with plenty of soap and water (do not use solvents). Prolonged contact with the skin should be avoided, especially where the user has an allergic reaction to epoxide materials. Always wear gloves and eye/face protection is necessary. Observe personal hygiene, particularly washing the hands after work has been completed or at any interruption whilst work is in progress. Care should be taken when removing gloves to avoid contaminating the insides. In case of accidents seek medical advice.


Spillage of any of the component products should be absorbed onto sand or other inert materials and transferred to a suitable disposable vessel. Disposal of such spillage or empty packaging should be in accordance with local waste disposal authority regulations.
