Product informations - PNZ-YELLOWING-PROTECTOR
Solvent-free wood yellowing protector for inside and outside
Properties:
Preventative, ready-to-use, solvent-free wood enhancement preparation to reduce natural yellowing of wood by UV exposure. Significant reduction in the effect of shrinkage, cracking and swelling caused by crystallisation and hardening due to dampness in the capillaries, serving to extend durability of the wood and subsequent coating systems.
Area of use:
PNZ-VERGILBUNGSBLOCKER ((PNZ-YELLOWING-PROTECTOR) protects against darkening, greying and yellowing for years, especially for light woods, such as maple, birch, fir, spruce and all pines, improving the dimensional stability and lifespan of these timbers. Discolouring due to variable incidence of light is greatly reduced, e.g. with furniture and floors (under carpets), ceilings and wall panelling, garden sheds and wooden houses, as well as other exterior timbers.
Usage:
Untreated wood must be clean, dry (under 18 % wood moisture) and free of grease. Sand off already yellowed timber down to the light bare wood, as PNZ-VERGILBUNGSBLOCKER is not a chemical bleaching agent. Stir PNZ-VERGILBUNGSBLOCKER and apply on all sides by hand rolling, brushing dipping or with an automated roller. May also be applied on a production line. Application temperature not under 8° C. The treated wood can be stacked immediately without sticking and may be reworked with all PNZ products after drying. For exterior use, timber at risk from blue mould and fungi should be treated before the final coat (e.g. with PNZ-IMPRÄGNIERGRUND W (PNZ-IMPREGNATION-PRIMER) W, PNZ-HOLZLASUR (PNZ-WOOD-VARNISH), PNZ-AUSSENÖL (PNZ-EXTERIOR-OIL).
Drying time:
Approx. 12-24 hours, depending on absorbency, humidity and temperature.
Coverage:
Approx. 30-120 ml per sqm. depending on the wood type and surface (planed or rough sawn).
Storage:
Cool, but frost-free, seal can tightly.
Cleaning:
Clean tools with soap and water.

Some red woods, such as rosewood may become lighter.
