Topclear

Topclear is a cleaner for Sudlac shading and diffusion coatings. With Topclear, the grower picks the moment when the roof is cleaned.

It is diluted with clean water, then sprayed onto a dry roof, by hand or by machine. The rain then does the rinsing. Topclear goes onto any greenhouse type.

Topclear cleans the roof when the crop needs it

Sudlac coatings are applied to optimise light conditions under glass. In early autumn, natural light intensity drops and crops then need all the light they can get. Topclear cleans off the coatings on the greenhouse roof.

The range holds two cleaners, one for each family of coatings. Topclear cleans off shading coatings such as Eclipse LD, Eclipse LD² and Transpar. Topclear Fuse cleans off the Optifuse and Optifuse IR diffusion coatings.

20 minutes

of working time

Once sprayed, Topclear needs 20 minutes at least to work before the rain rinses the roof.

1 application

is enough

The rain finishes the job after spraying, so 1 application is enough to clean the roof.

2 versions

for the whole range

Topclear handles the shading coatings and Topclear Fuse the diffusion coatings, which makes 2 versions for the whole Sudlac removable range.

Frequently asked questions

What is Topclear?

Topclear is a cleaner for Sudlac shading and diffusion coatings. The grower sprays it onto a dry roof, then the rain carries the coating away. That way the grower picks the moment when the greenhouse gets all its light back.

Which coatings does Topclear remove?

Topclear cleans off the coatings of the Sudlac removable range, including Eclipse LD, Eclipse LD² and Transpar. For the Optifuse and Optifuse IR coatings, Topclear Fuse takes over.

When should Topclear be applied?

Topclear is applied at the moment the grower chooses, usually in early autumn, when the crop needs all available light. Rain must be forecast in the following days, since the rain does the rinsing.

What types of greenhouse can it be applied to?

Topclear goes onto any greenhouse type, on glass and plastic roofs alike. The surface must be dry at the moment of spraying.

How is Topclear applied?

Topclear is diluted with clean water, then sprayed by hand or by machine onto a dry roof. It takes 12 jerricans per hectare, diluted in 1,760 L of water for manual application or 1,260 L for machine application.

Is rinsing needed after the application?

No, the rain does the rinsing. Topclear is therefore applied only when rain is forecast in the following days, after a working time of at least 20 minutes. Roof sprinklers are not suitable for that rinsing.
