Application of Silvanol wood preservative by coating (brush or roller):
- The wooden elements to be protected shall first be placed on stands or surfaces provided for this purpose.
- Protect the subfloor and flooring with an appropriate waterproof material, e.g., PVC sheeting.
- Start applying the first coat of Silvanol primary wood preservative with a dense, well-absorbing brush. Make sure that you are precise in your work and that you apply a generous coat of Silvanol on all sides of the selected wood element
- After application, wait between 30 and 180 minutes (depending on the time of year and weather conditions) for the Silvanol wood preservative to be properly absorbed into the wood and to dry.
- Next, apply a new generous application of the preservative with a brush over all the wood surfaces.
- When applying the preservative, it is important to adjust the amount of the preservative to the absorbency and processing of the wood surface (the specified application rate of Silvanol wood preservative is 200-250 g/m2, which is usually achieved with two rich brush applications; in case of poorer absorption, the number of applications should be increased accordingly).
- After the Silvanol preservative has been applied and the wood has dried properly (after approx. 48-96 hours, depending on the time of year and weather conditions), the wood can also be stained to the desired colour tone with Silvalazur water-based wood stain.
- The coating process usually ensures the wood preservative to penetrate approx. 1 mm into the wood. If the wood cracks after coating and being exposed to weather conditions, the cracks are often deeper than 1 mm, so it is advisable to repeat the coating process after a while to protect the newly formed cracks as well.
Wood protected with Silvanol, without additional surface protection with Silvalazur, must not be directly exposed to precipitation (possibility of leaching of the protected wooden elements). If you wish to additionally colour the protected wood or prevent patination of its surface, we recommend to use our water-based wood stains Silvalazur, which, in addition to their colouring function, also provide the wood with additional protection against weather conditions.
Application of Silvanol wood preservative by drenching or dipping:
- Before starting work, prepare a suitable wooden or metal frame (trough), lined on the inside with PVC foil (be sure to check the reactivity of the foil with the agent beforehand). If necessary, the trough can also be placed on two wooden or metal stands.
- Then dip or drench each wooden element in Silvanol in the trough previously prepared for this purpose (the wooden elements shall be fully dipped or drenched for approx. 10-30 seconds).
- After the wooden elements have been dipped or drenched, you should place them on the stand prepared for this purpose.
- Wait 30 to 180 minutes after the drenching or dipping process, (depending on the time of year and weather conditions) for the Silvanol primary preservative to be absorbed into the wood and to dry properly.
- After the first drenching process and after the wood has dried properly, repeat the dipping or drenching process once more.
- It is important to adjust the dipping time to the absorption and surface finishing of the wood surface (after the second dipping or drenching the wood must have reached the specified amount of 200-250 g/m2; in the case of poorer absorption, the number of applications shall be adjusted accordingly).
- After the application of Silvanol primary preservative has been completed and the wood has dried properly (after approx. 48-96 hours, depending on the time of year and weather conditions), the wood can also be stained to the desired colour tone with Silvalazur water-based wood stain;
- During the dipping process, the preservative only ensures protection of the surface and cracks of the wooden element, but does not penetrate deeper into the wood. However, the penetration of the preservative into the wood or the quality of the protection can be significantly improved by extending the dipping time.
Wood protected with Silvanol, without additional surface protection with Silvalazur, must not be directly exposed to precipitation (possibility of leaching of the protected wooden elements). If you wish to additionally colour the protected wood or prevent patination of its surface, we recommend to use our water-based wood stains Silvalazur, which, in addition to their colouring function, also provide the wood with additional protection against weather conditions. * If the wood is dipped in Silvanol for a longer period of time, the drying time of the wooden elements before any further work (painting, gluing, etc.) is extended; e.g., after a 24-hour dipping period in Silvanol, the wooden elements dry for approx. 2 to 3 weeks (depending on the drying conditions).
