Surface preparation

Surfaces must be free from oil, grease, wax, dirt or any other form of foreign matter. Spalled surfaces or those containing large blowholes and other defects i.e. cracks should be repaired using duraflex® or an a.b.e.® approved repair system.



Use a suitable paddle to stir with. (recommend a paddle mixer or other approved spiral paddle attachment on a variable speed drill. 

The preferred drill speed is between 280 and 640 rpm). Fill ¾ of the milky liquid into the bucket and with continuous stirring, slowly add grey powder. Mixing is continued, constantly moving the paddle around the drum, until a lump-free slurry is obtained.

Then add the remaining milky liquid whilst continue stirring. This should take a maximum of 5 minutes.



Use a soft block brush and spread the material to the required thickness. Do not add water to the material but dampen the surface.  Finish in one direction for a neat appearance


More coats

Apply a second coat and third coat of duraflex® to the whole area to be waterproofed. Apply coats at right angles to each other, allowing 16 hours between coats.

Apply 1kg per coat per m2, 3 coats required.

5kg covers approx.1.5m2 and

15kg covers approx. 4.5m2
