Sombrero liquid is a cost effective liquid shading product that is used for applying a temporary, even shade layer on greenhouses. Sombrero protects your crop against too much heat and sunlight and can be applied in different dilutions. Sombrero has a good wear resistance up to 3-4 months. The shade layer will wear off gradually, which means that the shading effect is reduced slowly and there is no need for a cleaning product. If necessary a second layer can be applied when a more intense or longer shading is needed.

What is Sombrero liquid

Sombrero is a liquid shading product that is used for applying a temporary, even shading coat on greenhouses. Sombrero protects your crop against too much solar radiation.


Mix Sombrero with the desired amount of clean water prior to applying it to the greenhouse surface with the appropriate spray equipment. The wear resistance is dependent on the dilution factor, the intensity of the UV radiation and amounts of rain.


First fill the mixing container with half the amount of needed water. Add Sombrero and start mixing. Add more water to get the total amount of needed mixture. Mix with sufficient force until it has formed into a homogeneous mixture. Scrape the bottom of the container to check that there is no residue. Now the mixture is ready to use.


Only apply Sombrero Liquid in fast drying circumstances to ensure the coating is fully dried before dusk. Rainfall the same day of application can damage the coating. Sombrero Liquid should only be applied at temperatures above 10°C (50°F).


Unopened container of Sombrero can be stored for 2 years. Stir before use if product is older than 1 year. Protect from freezing.
