FAQ - Frequently Asked Questions

1. Is this glue really water-resistant?
   Yes, it is D4 certified, the highest level according to the EN 204 standard. It is resistant to water, prolonged humidity and weathering.
2. Can it be used outdoors?
   Absolutely, this glue is perfectly suited for outdoor applications, including joinery exposed to rain.
3. Is it suitable for structural bonding?
   Yes, its high mechanical resistance allows for durable and strong bonding, including for load-bearing wooden elements.
4. Is she expansive?
   Yes, slightly. This expansion helps to fill small gaps, but it is recommended to tighten the pieces well to avoid excess foam.
5. Can anything other than wood be glued?
   Yes, it also adheres to stone, concrete, metal and some rigid plastics.
6. Is it suitable for damp rooms (bathroom, kitchen)?
   Yes, that's actually one of its main uses thanks to its high resistance to humidity.
7. Can the glue be sanded or painted?
   Once completely hardened, the glue can be sanded. It can also be painted, but a test beforehand is recommended.
8. Should the wood be moistened before application?
   On very dry wood, slight humidification can improve the polymerization reaction, but it is not mandatory.
