To be protected, the wood must be painted or varnished. The painting will be able to dress an ordinary wood or even to hide a damaged wood, by a decorative white or colored finish. But a beautiful wood, even veneer, will be enhanced by a varnish whose transparency and thickness will strengthen the hue and veining (madrure) of its essence.

Preparation of the door before opening
1. The old varnish of this door, gives obvious signs of aging and no longer assumes its decorative function of enhancement of the door that protects.
2. In the case of a landing door, its release was excluded. On the other hand, the temporary disassembly of the accessories of its closure facilitates the sanding and varnishing work which can thus be carried out without obstacle.
3. Perform a manual sanding (more regular with a sanding block) of the old varnish. Its more or less degraded state will encourage you to either go back to the wood, or just to "watch" the surface. Check your work with the flat of the hand to detect (better than the eye) any remaining defects.
4. Once the sanding is finished, start with a vacuum to remove as much sawdust and dust as possible. Then pass the sanded surface of the door, a sponge very moderately moistened to remove sanding residue and prepare the door to receive its first coat of varnish.
Opening of the door
1. Use a high quality polyurethane varnish to carry out this work, preferably in aqueous phase, which you will dilute to 50% to achieve a first impregnation and attachment layer. Protect the ground, then with a flat brush, called "cod tail" of 30 mm wide, varnish the edges of the door.
2. On this impregnation layer, which will dry quickly, use a light sanding with a fine dry abrasive (00) to make this first layer mat and facilitate the attachment of the second which will be spent pure or very little diluted (5% ).
3. Do not forget to put on a wrinkled chamois skin to remove the remaining dust on the sanded varnish. Sand lightly between each thin layer and wipe the sanded surfaces for a good result.
4. Now pass the second layer with a wider cod tail (50 mm). In case of a thick varnish, it is possible to heat it (with the necessary precautions) to make it more liquid and easier to work rather than dilute it too much to obtain this result. It is always better to pass three thin layers than two thick layers.
5. Always work up and down, avoiding crossing layers at this level. Pass newspaper under the door to protect the entire floor because you have to open the door to varnish, at the same time as the center, the edges hidden by the foliage of the frame when closed. Let the last layer of varnish dry before refitting the closing accessories.
