Boron salt is used in preventive wood protection, but also in the treatment of pests. It is easy to use and extremely versatile. Our guide shows where the advantages lie.

In a nutshell

  • Boron salts are toxic, so caution is advised
  • simple and versatile wood preservative
  • helps against fungal infestation
  • effective insecticide
  • suitable for combating woodworms

What is boric salt?

Boron salts are so-called borates. These substances are effective against both insects and fungi and are therefore often added to paints and varnishes in their crystalline form. They serve as wood preservatives and are used, for example, in the impregnation of roof structures.

Uses of Boron Salt

The use of boron salts or wood preservatives containing boron salt makes sense for several reasons. Because the substances protect against:

  • Fire
  • insects
  • mushrooms

They are therefore suitable, for example, as impregnation.

Notice: Boron salts, on the other hand, do not help against water damage. This applies at least if they are not added to a paint or a corresponding paint.

possible applications

Boron salts can be applied to different. For example for:

  • insulation
  • Colours
  • wood protection
  • paints

The funds can therefore be attached as a solid substance between the outer and inner wall or spread on. Another option is to immerse the wood in a suitable solution.

Since boron salts can penetrate the natural material very well, the wood is protected all around. Dip impregnation is a bit more complex than painting or using solid building materials. However, dip-impregnated wood can be purchased ready-made or ordered. This is particularly recommended for larger projects, such as building a roof truss or building a tool shed.

Application against fungi

Fungi produce mold and rot, among other things. They can rot the wood and even pose a health hazard.

Boron salt solutions can solve this problem because they change the pH value and therefore do not offer a suitable breeding ground for fungal spores.

Application against insects

Insects can cause considerable damage to the wood. Among other things:

  • drill holes
  • food marks
  • instability
  • impurities

Boron salt makes the wood repellent to insects.

insulating materials

As a substance in insulating materials, boron salts are harmless. However, this only applies as long as they do not come into contact with water. Because otherwise they can be washed out and then pose a risk.

Paints and varnishes

Paints and varnishes that contain boron salts and boron solutions are actually well suited for indoor use. They are easy to use, effective and inexpensive. In addition, they are odorless. So there is no harassment.

However, these substances should not be used outdoors, because there is a risk that borates will be washed out of paint or varnish and thus penetrate the floor. Since it is a toxic substance, it should be avoided.

Paint over boron salt

Whether it is dip-impregnated or kettle-impregnated wood, for outdoor use and for safety, the material should be given an extra coat of varnish. This prevents toxic boron salts from dissolving.

protection during uses

Since borates are dangerous substances, appropriate protective measures must be taken when they are used. That means:

  • latex gloves
  • mouthguard
  • safety goggles

Notice: Direct contact must be avoided at all costs. Comprehensive protection is advisable even when painting wood to avoid risks.

frequently asked Questions

Is boric salt toxic?

Yes, borates or borate salts are toxic. Since these are crystalline substances, however, they do not outgas. However, they can be inhaled in the form of dust, for example. They can also cause problems if they come into direct contact with the skin.

Can boric salt also be used dry?

To protect the wood, the salt must have been dissolved in a liquid. Otherwise the agent cannot penetrate the wood. It should also not be used dry against fungi or insects, as the dust can be dangerous.

What do boron salts not help against?

Borates do not help against the effects of the weather. Appropriate other means must be used for this purpose. However, boron salts can occur in the mixture so that as many dangers as possible are excluded.
