A glazing colorless antiseptic for wood is both an impregnation to reduce paint and varnish consumption, and a disinfectant, and a finishing layer. Translucent and transparent products (for example, Teknos TEKNAL 2460 primer for outdoor work) are tinted in any color, are well absorbed into the pores of timber, logs, and picket fences.
For covering or glazing paint, specialists from the LesoBirzha company recommend using the quick-drying composition Teknos AQUA PRIMER 3130, the alkyd-adhesive product Teknos TEKNOL 1881, and the iceland mobile database antiseptic Teknos VISASOL.

Consumption of antiseptic on different types of wood
The consumption of wood preservative per 1 m2 depends on the type of lumber. Edged boards without planing and brushed products have high porosity, so their absorption capacity is high. If you paint such a board without preliminary impregnation, you will need twice as much paint and varnish material as on a surface treated with a primer. The paint will lie unevenly, and after drying, spotting will appear.

When planing wood, its pores close, and absorption decreases accordingly. When buying wood preservative, calculate the consumption per 1 m2 as follows: 100 ml for planed board and 150 ml for edged board.
