Removing Sudlac paints with Topclear


Mix Topclear with the necessary amount of clean water. Apply the solution evenly onto a dry greenhouse surface under dry weather conditions and a minimum temperature of 5°C (40°F) .

Minimal reaction time is 20 minutes before rinsing with water or brushing. Considerable rainfall will wash away the coating. Only apply Topclear if considerable rainfall is expected in the next few days. Removal with roof sprinklers is not recommended.

For removal of Optifuse and Optifuse IR:

Apply Topclear in the advised amount and dilution within 3 days before considerable rainfall. A brushing machine should be available in case the cleaning result is not satisfactory.


First fill the mixing container with half the amount of needed water. Add Topclear 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. Now the mixture is ready to use.


Shake before use. Keep from freezing


Rinse water can run off into surface water if surrounding waterways are suitable in size and water volume. Should the rinse water run into the basin, test suitability before use as the pH might increase.
Sudlac is involved in Responsible Care®. 


The use of safety glasses and mask are recommended when handling or applying Topclear. In case of contact with skin or eyes, rinse thoroughly with clean water. If ingested, seek medical attention.
