Andrejštajn: renovation of wooden window frames

Video with Andreshtjan · Slovenian and English versions

When the old polish no longer performs its function

Old wooden windows have character, but a cracked and peeling dark brown coating needs reconstruction. In a close-up episode, I show the wear of the varnish, an overview of the wood and a gradual preparation of the window frame for new protection.

Review and careful preparation of the basis

First I look at the state of the wood. Before removing the old coating on the less visible part, I try the selected procedure. The animation shows pulse laser, protected glass and suction. I check the suitability of the process and setting for concrete wood, coating and frame state.

Removal of varnish does not remove damaged or decayed wood. After cleaning, therefore, I arrange the damaged parts and prepare the substrate for the new coating.

New protective coating

On dry and properly prepared frame I apply an outer protective coating suitable for this wood and intended exposure. I follow the manufacturer’s instructions regarding the application conditions, the number of layers and the drying time. The final scenes show wood structure and raindrops on the protected surface.

The sun, rain, wind and temperature changes gradually burden the coating. I regularly review the frameworks and restore protection in time. Video is an illustration of the workflow, and the concrete implementation is adapted to the state of the object.

Equipment and additional instructions

Below are links to renting a pulse laser, preparing settings, documentation for wood and protective equipment. At the Council of Blacks we can also check the implementation of the renovation by agreement.
