Steps to maintain a wooden gate and apply a varnish durably.
Buy a quality varnish, your portal will be protected for a period of between five and ten years.
Before applying the varnish, disassemble the hardware. You can then treat the wood below, but also repaint with a special metal paint (handles, plates, etc.).
The opening must be done during a day without wind. Otherwise, dust and impurities stick to the freshly laid varnish.
Work preferably in the morning and evening (avoid the hottest hours).
Block the open leaves until the varnish is dry.
Promote the adhesion of wood
On some wood (exotic in particular) the varnish adheres more difficult. The application of a layer of bottom preparation, (with a cloth or a brush) reinforces the adhesion.
Stir the varnish and apply it
Pass the varnish in a thin layer, with a flat brush in the direction of the wood grain. Stir the contents of the pot to homogenize the product. Load the brush little to prevent sagging.
Let dry and pass a second layer
Between two coats of varnish, respect the drying time recommended by the manufacturer. Emphasize assemblies and areas most exposed to the weather.
