Has anyone ever used self-made, eco-friendly sealing compound for outdoors?
- What recipe?
- How long does the recipe you used last?
I intend to use this sealing compound to stop wasps from getting in and out of my walls and removing styrofoam insulation (damn wasps) to build their nest.
- The gaps are no more than 2 centimeters wide;
- Environment is central Europe, not too warm, not too moist climate;
- It is to fill the gaps between wood planks and concrete.
