ᐅ UV Protection for Wood to Prevent Darkening Over Time

Hello everyone,

what are the practical experiences regarding UV-protective stains/oils/waxes/"products" for interior wood to prevent it from darkening over time? Does this work well, or does it only delay the darkening by a few years?
Product recommendations are also welcome.

Thank you very much

The parquet expert told us yesterday that tung oil is the best option for preserving the wood in the long term.

I have a new solid laminated spruce ceiling. Therefore, mechanical stress can be considered negligible.

It is also supposed to help prevent fading.

The company diotrol offers oil-based products that prevent darkening over time.
