Product description

Q4 White is an extremely weatherproof and optimally adjustable shading agent specifically designed for glass, plastic film, polycarbonate and acrylic. Even at lower shading percentages Q4 White will not cause excessive wear to the ridge and it is very wear resistant, yet easy to remove with Removit. Therefore Q4 White is the best maximum weatherproof screen product on the market. Q4 White is patented.

User experiences show minimal wear off on the apex of the roof with the use of Q4 White. It is very important to shade the top of the greenhouse because the sunlight shines from early morning until late in the evening.

Usage Q4 White

Calculate the number of buckets needed by reading the desired percentage from the table above. Add the shading agent to clean water while stirring. Use enough spraying liquid to evenly divide Q4 White on the roof of the greenhouse. The amount of spraying liquid needed for your roof depends on the manner of application. Use 1.200 to 1.400 liters per hectare when the shading agent is applied mechanically. When the choice for manual application has been made, we recommend to use 1.500 to 1.700 liters per hectare.

We advise to stir the solution during the process of application. Apply Q4 White on a dry and clean surface.

Q4 White can be removed from the greenhouse easly pand safely at any moment with Removit. Some rain will wash off Q4 White after applying Removit in the right dosage. Q4 White also can be washed off manually if it does not rain for a long time.

Please note

Do not use Q4 White in combination with other shading products. Prevent the product from entering the basin during application or removal. Store frost free.
