With the renovation of our living room we have placed retaining walls. As a result, the walls have become wider and the old windowsills no longer fit in their place. That is why we massief beuken window sills from We initially planned to paint the windowsills white, but we liked the wood so much that we opted for a matte varnish. We are very satisfied with the result!

Small adjustment, big effect!

The frame widths were different, so we ordered planks of different widths. We milled a 3mm radius round edge on the protruding part. Then we secured them with polyurethane foam. The plasterer did a good job on it. We finished the seams with the window frame and the walls with acrylic sealant. Finally, we coated it twice with transparent varnish. This brings out the wood color more strongly. Finishing before plastering is recommended, but we wanted to keep all options open in terms of finish.
