Glaze garden furniture - does it make sense?

The fact that you should protect garden furniture made of wood as possible from the effects of the weather, comes to light. But there are often ambiguities in the difference between paints, wood oil and glazes. What the glazing of garden furniture brings, read here.

Transparency of glazes

A glaze is indeed a coloring, but still transparent coating. This has the advantage over paints that the wood grain still shines through. Especially with high-quality wood species, one would like to preserve the beautiful grain.

Protective function of glazes

Glazes protect the wood surface from damaging influences:

  • UV radiation
  • humidity
  • sometimes also from pests

UV protection

Glazes offer one UV protection for the wood. Sunlight with its UV content causes wood to turn gray over time and become unsightly. The more the furniture is protected from the sun's rays, the longer they stay beautiful. The lignin in the wood does not decompose then and the fading of the wood is missing, as well as the cracking.

Clearly, dark glazes offer more protection to the wood than bright ones, as they block out more UV radiation. For some glazes, a special UV protection is integrated - but you can not always rely on that.


Since even a glaze creates a dense surface layer, it offers consistently good protection against moisture. Here, however, one must distinguish between thin-film and thick-film glazes. The difference is explained below.

pest Control

Most have glazes no blue stain integrated. This remains reserved for "real" wood preservatives. You should always apply a blue stain primer before applying a glaze.

The blue is a fungus that affects many species of wood. Although it does not destroy the wood, it discolors it, but it brings moisture into the wood and makes it swell easily. The affected wood is then very tempting for other pests.

Thin film glaze vs. Dickschichtlasur

The two types of glazes differ - as the name suggests - by the layer thickness. Thick-film glazes form a rather varnish-like, thick seal that protects the wood well. Thin film stains only form a very thin film on the wood surface.

Thick-film glazes usually provide better protection, a thin-layer glaze still allows a small amount of moisture to pass through and the glazed wood can still weather.

Tips & Tricks

Thin and thick film glazes can not be distinguished by the consistency of the product but only by the final result when applied. Therefore always pay close attention to the packing labels.
