Kool Ray Liquid Shade Semi-Permanent Greenhouse Shading - 5gal Concentrate

Trusted Since 1953 - Kool Ray Liquid Shade Semi-Permanent Greenhouse Shading, 5gal Concentrate

Kool Ray Liquid Shade is a spray-applied, semi-permanent greenhouse shading concentrate with a proven track record dating back to 1953. When diluted with water and applied to external glazing, it provides an economical and effective alternative to mechanical shading and ventilation systems. Its bright white formulation reduces interior greenhouse temperatures during peak growing seasons while still allowing essential growth wavelengths to reach your plants. Made from pure clays, minerals, and non-hazardous ingredients, Kool Ray is environmentally safe, UV-resistant, and compatible with most standard plastic glazing - helping to prolong its service life with regular use.

Key Features & Benefits

• Semi-Permanent Formula: Adheres to glazing through the growing season and gradually weathers off with precipitation exposure, automatically allowing more light as the season transitions - no manual removal required.
• Natural Ingredient Formula: Made from pure clays, minerals, and non-hazardous components including titanium dioxide, limestone, and silica. Environmentally safe and compatible with most glazing materials.
• UV-Resistant: Resists UV degradation, maintaining its shading effect throughout the season while helping protect plastic glazing from UV-related breakdown.
• Trusted Performance Since 1953: Decades of proven use in commercial and hobby greenhouse operations worldwide provides confidence in its reliability and effectiveness.
• Cost-Effective Alternative: Replaces or supplements mechanical shading and ventilation systems at significantly lower cost per square foot of coverage.
• Compatible with Common Glazing: Suitable for application to greenhouse glass, rigid plastic panels, and plastic films.

Who Should Use This

Kool Ray Liquid Shade is the right choice for greenhouse growers - from hobby greenhouses to large commercial operations - who want a proven, low-cost shading solution that applies easily, performs reliably through the season, and gradually self-removes as growing conditions change. It is especially valuable as a cost-effective substitute for mechanical shade systems on poly or glass-covered structures.

Compatibility

Compatible with greenhouse glass, rigid polycarbonate and acrylic panels, and standard plastic film glazing. Dilute at the standard rate of 1 part Kool Ray to 8 parts water before applying with standard agricultural spray equipment. Coverage varies based on application, applicator, and dilution ratio. For enhanced adhesion and extended service life, use with X-Tra Stick Adhesive Additive (sold separately). pH: 7.25. Signal Word: Danger - review SDS before use.

Frequently Asked Questions

Will Kool Ray Liquid Shade wash off on its own?

Yes. Kool Ray is a semi-permanent formulation that gradually weathers off with rain and weather exposure over the course of the growing season. This natural wear-off allows progressively more light into the greenhouse as the season progresses and temperatures moderate - a built-in benefit for most growing operations.

What is the standard dilution ratio and coverage rate?

The standard dilution ratio is 1 part Kool Ray to 8 parts water. Coverage varies by application method and dilution ratio; consult the product label for current coverage guidelines and adjust dilution based on your specific shading requirements.

Is Kool Ray safe to use on plastic greenhouse film?

Yes. Kool Ray is UV-resistant and compatible with most standard plastic glazing materials. Regular use can actually help prolong the service life of plastic glazing by reducing UV exposure and heat stress on the material.

What are the active ingredients in Kool Ray Liquid Shade?

Kool Ray contains water (72%), titanium dioxide (10%), limestone (10%), amorphous silica (1%), and a small amount of solvent-dewaxed heavy paraffinic distillate (0.10%). It is formulated from pure clays and minerals and is considered non-hazardous in normal use.
