Aquadur Primer®


Two-component, water based, epoxy coating / primer


AQUADUR is a two-component, water based, epoxy coating. It has a track record of more than 20 years of successful use as primer for the HYPERDESMO® line of products, as well as other Alchimica polyurethane based products.


It is certified as "Class III” water and humidity barrier, which makes it ideal for applications subject to negative pressure / rising humidity.


An easy to use and safe (zero VOC) product with many applications besides priming.


Use as:

  • Primer in applications with rising humidity / negative pressure (tanks, pools, foundations etc.),

  • primer for other systems, e.g. epoxy or polyurethane based, cementitious,

  • sealing coat for concrete,

  • adhesive layer between old and new concrete,

  • water / humidity barrier.


Shelf Life:

with roller in one or two coats with total

Recoat time cannot be determined in terms of hours since it is highly dependent on weather conditions: It can be as low as 5 hours during summer and as high as 24 hours during winter.


Use the following rule of thumb to determine
when recoating should take place. Recoat (with
AQUADUR or HYPERDESMO®) once the colour on the current coat goes from milky white to
transparent. Also check that the current coat has hardened to the degree where it can no longer be punctured by finger nail.
