ᐅ Reinforcement mesh on discolored insulation?

Hello,

I built a house in 2006-2007, doing all the work myself with friends and family. Unfortunately, I became seriously ill during the construction period and couldn’t finish the build. I was bedridden for many years and was only recently operated on. Now I am feeling relatively well again, but I have a problem with the exterior wall. When I fell ill, we had just reached the stage of insulating the house.

The insulation (12cm (5 inches)) had been applied to the bricks, and one side of the house was completed with the reinforcing mesh. The remaining walls were exposed to the weather for several years. The insulation has now turned yellow instead of remaining white. I’m wondering if I can still apply the reinforcing mesh onto the insulation and later add the plaster, or if the insulation needs to be completely replaced?

I hope I was able to explain myself clearly ;-)

As long as the insulation has remained dry, it is not a problem. Apply an adhesive primer, and it should work. However, if water has gotten behind the insulation, it needs to be replaced. Although this requires significant effort, it is worthwhile.
