Why Elastic Adhesives Lead to a More Powerful Bond Compared to Mechanical Fixing
A big advantage of elastic adhesives or bonding over traditional mechanical fixing with screws or nails is the larger fixing area and consequently, a far more homogeneous and uniform distribution of any load or stress.
The only disadvantage is the lack of penetration depth when compared to screw fixing and therefore, the need for sufficient surface strength of the elements to be joined plus good adhesion of the adhesive for a durable, strong bond.
Ultimately, elastic adhesives lead to a faster, safer and more durable bond.
- Fewer tools
- Clean installation
- No initial fixing
- No object damage
- Installation on uneven surfaces
- Good indoor air quality, lowest VOC
- Stress compensation and transfer
- No humidity bewteen objects
- No corrosion
Sika's Wood Floor Adhesives for Long-Lasting Wood Floors
Sika’s elastic adhesives have now proven themselves over many years, giving wood floors a durable, long-lasting, flexible but firm and resilient bond to the substrate. Our latest products continue the development of this expertise and follow the path of sustainable bonding with adaptable mechanical properties, all to the latest and highest environment, health and safety (EHS) standards.
The adhesive must hold the wood in place, connect it to the underlying screed and transfer stress originating from the natural expansion and contraction of the wood to the generally rigid screed. The undesired but natural movement of the wood can become visible in cupping, joint formation, or in extreme situations failure of the adhesive or screed. Our SikaBond® adhesive line strongly bonds wood to most substrates, including concrete, plywood and levelling or patch underlayments that have been properly prepared.
