Glaze wooden doors and emphasize the natural grain

Unlike lacquering, wooden doors are glazed if the natural grain and texture of the wood is to be visible. Glazes can be neutral in color and completely transparent or influence the appearance of added color pigments. Depending on the load, different glazes can be used.

Lasurarten and properties

Who wants to work up old doors and renovated a wooden door, often wants to expose and preserve the natural wood surface. When glazing, doors are painted to preserve and protect the exposed wood look.

Depending on the place of use and the expected loads, there are three types of glazing:

  • Thin-film glaze: Used indoors. Water-soluble acrylic stains with low solvent content produce less evaporation than alkyd resins with high solvent content.
  • Middle-layer glaze: They are mostly used for interior sides of exterior doors and are a compromise in terms of solvent content and effectiveness against wood pests and UV radiation.
  • Thick-film glaze: Used on doors on all exterior surfaces, protects against fungi, wood sponges, moisture, fading and UV light when pigmented. It is highly solvent-containing and odor-intensive.

Penetration depth and outdoor area

Since the glaze penetrates deeper into the wood when glazing than varnishes do, care should be taken to ensure perfect drying of the doors and longer drying time after glazing. If old colors are removed by means of pickling in preparation, a suitable special glaze must be used.

When exterior doors are glazed, transparent glazes without pigments should not be used as they do not provide protection against UV light. In addition, it is recommended to use at least one medi- um layer, better still a thick layer glaze.

This is how you glaze doors

  • Glaze (thin medium or thick layer with / without UV protection)
  • Grit with 400 grit
  • Plastic brush
  • masking tape
  • Grinding machine or block

1. Preparation

The surfaces of the door that you want to glaze must be clean dust-free and show the wood image that should be visible after the glaze. The glazing can influence the intensity, brightness and color of the door surfaces, but does not obscure anything.

2nd primer

Apply the primer recommended by the manufacturer of the glaze and allow it to dry up to three wraps.

3. sanding

Sand the primed surfaces slightly.

4. Glaze

Apply the glaze according to the manufacturer's instructions.

Tips & Tricks

The glazing of doors forgives irregularities in quantity order more than lacquers doing. Nevertheless, you should check the dried order after each operation with an oblique light source.
