How to choose wood protection with silicon – use, tips and frequently asked questions

What is wood protection with silicon and why choose it?

Wood preservatives with silicon (silicate/silicon-based products) are water-repellent and provide protection for the wood against moisture, dirt and growth without the use of harsh chemicals. Many silicon products are based on natural ingredients and are more environmentally friendly than traditional oil-based or heavy metal-containing treatments. After a few months in sunlight, the wood often develops a beautiful silver-gray patina that many people appreciate.

Common questions users search for

1. Where can I buy wood protection – is it available in large hardware stores like Home Depot or similar?

Many hardware stores and paint and wood specialists stock wood preservatives, but the range varies between chains and countries. In North America, silicon-based options are often available at larger chains or specialty stores for outdoor treatment. In Sweden and Europe, specialist paint retailers and retailers of natural area products are the best place to look for silicon-based wood preservatives.

2. Can wood protection be used for wood that is below ground level?

Wood that is to be below ground level is exposed to constant moisture and biological degradation. Many silicon-based wood preservatives provide good surface-bound moisture repellency and reduce fouling, but buried wood often requires more robust impregnations intended for ground contact, sometimes with pressure impregnation or special preservatives approved for below-ground use. Check the product's technical data sheet recommendations before use on buried wood.

3. Can wood protection be used indoors?

Some silicon-based wood preservatives are formulated for outdoor use and may have properties (scent, binders) that are not optimal for indoor use. For indoor use, you should choose products that are approved for interior surfaces, are low in VOC, and safe for indoor environments. Always read the product label and technical information — products specifically marked for interior use are preferable for furniture and interior panels.

4. Is wood protection with silicon suitable for fences and planks?

Yes. For fences and facades, wood preservatives that are water-repellent and dirt-repellent are very useful. Silicon-based products help keep the wood surface cleaner for longer and reduce the risk of algae and mold growth. They often give a natural, matte finish that ages to an attractive silver-gray tone, which many find well suited for outdoor environments.

5. Are there brown/tinted wood preservative products (home hardware brown wood preservative)?

Yes — wood preservatives are available in both clear, tinted and pigmented varieties. While many silicone products leave a natural or silvery patina over time, there are formulations or combinations with pigments if you want a specific color tone (e.g. brown). If you want color + the benefits of silicone, check to see if the manufacturer offers tinted versions or recommends overcoating with compatible pigmented glazes.

Practical advice for application and maintenance

• Prepare the surface carefully: clean, remove mold and loose dirt before application.
• Apply according to the manufacturer's instructions — often with a brush, roller or sprayer.
• Several thin layers provide better penetration than one thick one.
• Allow the surface to cure/age in an outdoor environment to obtain the desired silver-gray patina.
• Inspect and supplement the treatment regularly, especially for exposed surfaces such as fences and ground-level structures.

Recommendation

If you are looking for an environmentally friendly, water-repellent wood protection that provides a dirt-repellent surface and beautiful aging, consider options based on Nano Silica Silicon. An example of such a product is

— perfect for facades, terraces and fences where you want low environmental impact and long-lasting protection.

Summary

Silicon-based wood preservatives based on Nano Silica offer a good balance between environmental friendliness and performance for many outdoor projects.

For ground contact or highly exposed structures, special impregnation methods may still be necessary. Choose the product and method according to the application — and always read the technical data sheets for detailed recommendations.
