If you favor an ecological approach you should start from here to preserve your wooden
hardware. The ecological primers are acrylic and replace linoleum. They are the first substances to apply to your material (boxes, bases, caps) before proceeding to paint. You should make one two applications before painting.
The ecological primer should be diluted with water only. Yield 10-12 m2 / Lt / layer.
* If you use ecological primers, you should also use ecological paints.
