![]() | Question:
Please can you advise the anticipated lifespan of the M922M in a domestic dwelling, protecting the face of a steel column which is partially built into a cavity wall, which is potentially damp. The steelwork will be off-site primed with C400V3 and will receive a brush applied coat of 400 microns M922M to affected surfaces, before being built into the wall. The face of steel will be approx 25mm distance from the inside face of the outer leaf of brickwork (i.e. not in continual contact with outer leaf). |
Answer:
The manufacturer advised the timescale can only be given as a guide in this instance. The difficulty is that during the coatings life it should be inspected and maintained but I believe this will not be possible. Therefore approximately 15 - 25 years | |
