The benefits of ProtoxProtect

With ProtoxProtect you can prevent any attack of mold on porous surfaces both inside and outside. One of the great advantages of the product is the effect on surfaces that occasionally get wet, on thermal bridges in the home and on moist building materials. Here we are particularly thinking of rafters and roof veneers in roof spaces with poor ventilation and condensation due to undercooling and poorly insulated outer walls. Mold grows especially well, but with ProtoxProtect you can protect the surfaces and avoid mold.

ProtoxProtect also prevents the ugly discolorations that mold often leaves behind, even when the mold has been removed. The agent also fights discolouration outdoors on e.g. wood, wooden decking and tiles, so you can remove them completely.

ProtoxProtect has been tested and approved

ProtoxSkimmel is not classified as dangerous, harmful to health or similar. In fact, the product is recorded/registered in the database for building products that can be used in Swan-labelled construction. And according to one indoor climate report made by Eurofins A/S does the product not pollute the indoor climate after use.

ProtoxProtect has MAL 00-1.

Application of ProtoxProtect

What is ProtoxProtect?

ProtoxProtect is a primer to prevent mold and discoloration from mold. The agent is particularly suitable for thermal bridges, damp building materials and building parts that occasionally get wet. ProtoxProtect can be used both indoors and outdoors. The product has a faint acetone-like smell until it dries, after which the smell disappears completely.

Where do you use ProtoxProtect?

  • May be used both indoors and outdoors
  • Is particularly suitable for porous surfaces such as damp wood, plaster, concrete, eternite sheets, masonry and wallpaper
  • Use at a temperature above 5°C

If the product is used on painted surfaces, gloss differences may occur. Make any a small test before use.

NOTE: ProtoxProtect contains a binder that can form a film after drying on non-absorbent surfaces such as glass, plastic and glazed tiles. The membrane can be difficult to remove so remember to uncover non-absorbent surfaces.


Before treating with ProtoxProtect, the surface must be as clean as non-infested surfaces. If there is already discoloration and mold growth, the affected surface must therefore first be disinfected or washed down with ProtoxHysan.

ProtoxProtect is ready to use and must not be diluted further.

The range is 3-5 m² per litres, but up to 6 m² on a very low absorbent substrate.

The product must be stirred before use.

Always read the safety data sheet before using the product.


ProtoxProtect can be applied with a brush, by spraying or by dipping.

The treatment with ProtoxProtect can possibly be combined with mechanical cleaning such as ice cleaning, sandblasting, milling or the like.



The drying time is approx. 8 hours.

Utensils and tools are cleaned with soap and water after use. If there is spillage that has dried in, you can try to remove it with primer, acetone or the like.

ProtoxProtect is stable for at least 2 years from the production date in unopened packaging and must be stored frost-free.

Leftovers and empty packaging must be handed over to the municipal waste management system.

After using ProtoxProtect, it can be treated with most surface products. However, it is the user's own responsibility to test the product's effectiveness for the specific task after treatment with ProtoxProtect.

After finishing treatment outdoors, the surface should be treated with a pigmented (covering) and water-repellent surface product to protect the wood from degradation caused by the sun's UV rays and washing out by rain. The item must be completely dry before finishing. The finishing should be done within a month.
