Immortality of Wood: Varnish and Impregnation Technologies

Wood is a living organism; it continues to breathe, expand, and interact with its environment even after being cut. Leaving it unprotected causes it to turn gray (UV burn), rot (fungus), and lose its form.

/Enemies of Wood 1. **UV Radiation:** Sunlight breaks down the "lignin" (natural glue) inside the wood. The surface becomes fibrous and turns gray. 2. **Moisture:** Water causes wood to swell and crack when dry. It also prepares an environment for fungus and mold. 3. **Biological Pests:** Woodworms and termites.

/Protection Shield: Varnish or Oil? - **Water-Based Exterior Varnishes:** Renga Plus Aqua-Wood series moves with the wood thanks to its flexible structure, does not crack. Blocks the harmful effects of the sun thanks to UV filters. - **Impregnation Primer:** A chemical solution applied before varnish, penetrating the pores of the wood, protecting it from the inside, preventing fungus and insects. - **Teak Oil:** Natural care that nourishes the wood without creating a film layer for exotic trees (Teak, Iroko). Recommended to be applied twice a year.
