Wooden furniture, tables accompany us through everyday life—supporting work, meals, creativity, and conversation. But even the best wooden surfaces face a natural challenge: the imperfections that make wood beautiful also require skilled repair. Now, a new Sika technology is transforming how these repairs are done.

Celebrating the Beauty of Natural Wood

Wood Knots, cracks, and unique grain patterns give each piece of wood its own character. Instead of hiding these features, modern furniture design embraces them. When treated correctly, they highlight craftsmanship and turn ordinary tables into distinctive pieces full of authenticity and charm. 

A Joint Innovation for Better Furniture 

To enhance this process,  SikaBiresin® AP350, a new 2‑component polyurethane filler optimized for oak tables, was developed and brought to the market. Powered by Sika’s Curing by Design technology, the filler ensures: 

  • Optimized curing time 
  • Simple use through 2C cartridges (no manual mixing) 
  • Strong, clean filling of cracks and knots 
  • Shorter repair and waiting times before sanding and oiling

Craftsmen can achieve flawless, professional results—faster than ever.
